This Swedish chocolate cake is not only one of the best I’ve ever eaten, but the easiest, too. One pan only and no whisking required. Just melt the butter and stir everything else in and you’re only 20 minutes away from oozy, gooey, richly chocolaty heaven!

Easy chocolate desserts like this always call my name, so when I saw it in one of those free supermarket food magazines recently, I filed it away in the ‘to make’ section in my head.Usually these ideas float around there for a long time before they (maybe) make it to the blog, but I couldn’t get this one out of my head.

Because, well, chocolate. And can you see how gooey and oozy and chocolaty it is? How could I resist? How can YOU resist?

What’s kladdkaka, anyway?

The recipe in the magazine was called Swedish chocolate cake, which in Sweden is called Kladdkaka. Apparently this is a very famous cake in Sweden and everyone has their favourite recipe for it. The cake should be very rich and chocolaty with a delicate crisp and chewy top but soft and gooey inside. A bit like a cross between fudgy brownies and a chocolate soufflé.

The easiest chocolate cake you can imagine… all in one bowl!

After I began to do a bit of research on this special-sounding Swedish chocolate cake, I found out from Top With Cinnamon’s Izy Hossack that there is a much easier way to make it than in the supermarket recipe I saw. So ridiculously easy that it only took me about 5 minutes to get it into the oven.

ALL you do to make this kladdkaka is:

  1. Line and grease one 18-20cm cake pan (a spring form pan is best).
  2. Melt the butter in a saucepan.
  3. Stir in sugar, cocoa powder, vanilla essence and flour.
  4. Bake for 20 minutes.

But look how incredibly chocolaty it looks!

I really think this easy chocolate cake is hard to beat … certainly as a quick chocolate desert to whip up for guests that looks quite impressive even though it’s only one tier and doesn’t have any kind of frosting.

So how do you serve kladdkaka?

Swedish chocolate cake doesn’t need any frosting or topping. Just turn it out and sprinkle generously with powdered sugar/icing sugar or cocoa powder.

There. It looks quite impressive just as it is, doesn’t it?

If you like, you can serve it with whipped cream and ice cream and some strawberries or raspberries.

I’ve made similar sticky chocolate things to this that tasted quite good too but they took 3 or 4 times longer to make. This cake only has SIX ingredients in it.

Just try not to overbake the kladdkaka because you don’t want to lose that lovely sticky gloopy-ness in the centre. The cake is done when the top is firm but breaks quite easily when you put a bit of pressure on it.

Can you make this Swedish chocolate cake ahead?

Yes! Make it a day or two in advance and keep it in the fridge if you like, then simply warm each piece separately in a microwave for about 20 seconds.

If there are any leftovers (and this is a big ‘if’!) pop them into the fridge and steal little bits every time you open the fridge. Well, this is what I always do. Oops. You’ll find when cold this chocolate cake tastes just like fudge! You could even cut it into small squares and tell your friends that it actually IS fudge!

Even Mr. Scrummy, who doesn’t usually like chocolaty cake things of any kind, loved this quick chocolate dessert. It was so scarily good that we ate half and froze the rest to stop ourselves from eating it all in one go.

This yummy chocolate cake would be perfect to serve to guests at Easter with mini chocolate eggs sprinkled over the top, or really for any special occasion.

To help you with this recipe: 

I like to use a 7 to 8 inch springform cake pan like this one to make this gooey chocolate cake. Because it’s such a gooey cake, it’s quite delicate when just cooked and this makes it really easy to turn out onto a plate or cake stand.

6-ingredient Gooey Swedish Chocolate Cake (Kladdkaka)

Quite possibly the quickest, easiest, gooey-est (and so best) chocolate cake you'll ever make. This has only 6 ingredients and takes only 30 minutes to make and bake from start to finish. A cake that is so perfect for serving to guests... or just scoffing at home in front on the TV!
Prep: 10 minutes
Cook: 20 minutes
Total: 30 minutes
Servings: 8 to 10

Ingredients 
 

  • ounces salted butter, (US = just over ½ cup, or just over 1 stick)
  • ½ cups cocoa powder, (plus 1 tablespoon) unsweetened, plus extra for sprinkling
  • cups sugar
  • 1 cup plain flour, (actually, just less than a full cup, about 0.85 cups)
  • 1 teaspoon vanilla extract
  • 3 eggs, lightly whisked

Instructions 

  • Pre-heat the oven to 180C/355F. Line the bottom of a 7-9 inch (see note below) springform cake pan with a circle of baking paper, then grease the paper and the sides of the pan.
  • Melt the butter in a medium saucepan, then take off the heat and set aside.
    4¾ ounces salted butter
  • Add the cocoa, sugar, flour and vanilla to the butter and stir a little. Then add the eggs and stir everything together until well combined.
    ½ cups cocoa powder, 1¾ cups sugar, 1 cup plain flour, 1 teaspoon vanilla extract, 3 eggs
  • Pour the mixture into the cake pan and bake for 20 to 25 minutes (see note below) until the top is set but the centre is still gooey (the top should be firm but crack under a little pressure from your finger).
  • Let the cake cool in the pan, then run a knife between the pan and the cake to loosen it. Turn out onto a plate or cake stand (see note below). Dust generously with cocoa powder and serve warm with ice cream or cream.

Notes

Recipe barely adapted from Izy Hossack’s recipe for Mail Online.

A note on which cake pan to use

I usually use a 9 inch spring form cake pan for this cake, because that's what I have, and it comes out as you see in the photos.
The original recipe that I adapted this from, however, states to use a 7 inch pan. I'd say that anywhere from 7 to 9 inches will work well. 
You might need to make the recipe a couple of times to get the baking time just right (yes, it's one of those recipes, but once you've nailed it, you've nailed it). See below for more hints on getting your cake just right!

Getting your cake just right

Although this is a super quick, easy and delicious cake, it can 'sometimes' (not always) take a bit of perfecting. If your cake still isn't cooked on top after 20 minutes, keep checking it every couple of minutes until it is. I usually find 20 minutes is about right, but of course it depends on your oven/the exact size of your cake pan etc.
One reader reported that the cake took 30 minutes in her oven. So the first time you make this might be a bit of an experiment to see how long you need to cook it in your oven!
You want to avoid overcooking the cake though, because then it won't be as deliciously gooey. 

After your cake is cooked...

You'll find that your cake is quite delicate just after cooking. Let it cool in the pan, then turn it out onto a plate or cake stand.
I usually hold a plate on the top, then invert it quickly. Your cake will then be on a plate, but it will be upside down. To turn it back the right way, I put another plate on the bottom of the cake and turn it back the right way.

Can you make this chocolate cake gluten free?

Yes! I officially tested this recipe using just almond flour in February 2020. It works just as well as it does with ordinary flour.
In fact if anything it's slightly more delicious (if that's possible) because you can very slightly taste the almonds. 
I haven't tried the recipe with gluten free plain flour, but I'm pretty sure you'd have no problem doing a straight swap. The recipe doesn't contain a lot of flour, so flour substitutions tend to work well. Good luck!
Serving suggestion: I like to serve this cake warm with ice cream on top. It's also delicious with fresh raspberries! Or elevate the dessert even more with this 5-minute raspberry puree - you won't believe how easy it is to make.
Love gooey chocolate cakes? If you love kladdkaka, you'll love this slightly less sweet and arguably slightly fancier Italian equivalent - torta tenerina. Try these gooey strawberry brownies as well.
Also love layer cakes? Try this easy chocolate orange cake with 3-ingredient ganache.

    I’ve made this twice in the past week! Such a great recipe. I’ve made other kladdkaka before but this one is the best. Thank you for sharing it!

    1. Thanks for the feedback, Bob. It’s good to know how it compares. I appreciate the feedback and hope you make this many times more! 🙂

  2. Hi, I was wondering if it is ok to use melted chocolate instead of cocoa powder in the recipe?

    1. Hello Nadine! I’ve never tried this so can’t say whether it would work or not but if you experiment with it, do let me know! I wouldn’t be surprised if it turned out amazingly! Definitely reduce the amount of sugar if you do try it, though. Ooh yum! 🙂

  3. Horrible, pure, raw & runny in the inside with very thin crust outside which fell apart when cut (even after cooled) It was like eating raw brownie mix.

    1. Hi Joy! I’m sorry you didn’t think much of your first attempt. This recipe is definitely worth persevering with, though. It sounds like yours was underbaked. Give it another go but just leave it in the oven for a bit longer. It’s done when it’s set around the edges but a skewer poked into the centre comes out with a few sticky crumbs on.

  4. AMAZING!! So delicious my partner and I ate half in no time!! It took closer to 30 mins in a 7 inch pan. I’ll definitely make this again and share it. Thank you!

    1. Thank you! So happy you liked it enough to make it again. It’s still a firm favourite in our house after many many years of making it.

  5. Hi! I have a 10-inch springform pan, do you think I’d need to make any modifications or should the recipe as is be okay? Thanks!

    1. Hi Corinne! What I’d do is increase all the ingredients by a quarter, apart from the sugar (you don’t need any more!). Lucky you, you’ll get a bigger cake! You may not need to bake for any longer but what I’d do is check after the stated cooking time and check again every few minutes from there. I find you sometimes have to have a trial run with this recipe anyway to check exactly how long the baking time is in your particular oven. Just don’t overbake! Runnier is better than overbaked! Good luck! 🙂

      1. Thank you so much! I can’t wait to try it out this week for my fiancé’s birthday!

    I’ve made this many times. My family loves it and requests it often. Tonight I’m trying it with almond flour instead of regular flour. It’s in the oven now. Can’t wait to see how it turns out!

    1. Hello Michelle. So good to hear this! I’ve made it with almond flour before and it works really well!

    Hi Helen
    I live in South Africa & we are currently experiencing a very cold winter. Tonight I made a beef & veg soup, but needed something rich to balance the menu!!
    I took you at your word that this was a quick, delicious recipe, and decided to go for it.
    Guess what?
    You were SO right!!
    It took me 10 minutes to mix the ingredients, and I baked it for 22 minutes, and it was very yummy!
    My hubby kept sighing & muttering “this is great”! He even licked the bowl clean!!!
    This recipe is a winner & a keeper.
    Thank you!

    1. Reading this on a Monday morning in Perth, Debbie, and so you’ve got my week off to a great start!

      I’m so happy this went down so well at your house. It’s a great easy dessert for when you’re cooking something special and want something yummy afterwards.

      Thanks so much for the feedback, and have a great week. P.S. I hope you get some warmer days soon! 🙂

    1. Hello Lauren! You don’t have to refrigerate it – it’ll last for a good few days just covered well on the counter. But if you do pop it in the fridge you’ll find it tastes more like fudge when chilled. Delicious either way really – still warm from the oven or chilled 🙂

  8. This looks incredible! I haven’t seen it mentioned anywhere but am wondering if you use natural or Dutch processed cocoa powder? Also, would this still be as good texture/baking wise with 1.25 cups of sugar instead of the 1.75 cups specified? Thank you!

    1. Hi Andrea! I’d stick with natural, but to be honest I don’t think it would matter if you used Dutch processed. It’s more of an issue if you have baking soda or baking powder in the recipe, which this recipe doesn’t (it relies on the eggs to rise a little). As for the sugar reduction, go for it! Some people have tried it and still ended up with a great result, so I feel confident saying you can do that. Good luck! Enjoy!

        Thanks so much, both for the recipe and your reply! It was outstanding using regular cocoa and 1.25 cups of sugar. I’m thrilled today’s test run went well, I’ll be making another for my Mom’s birthday next week. So grateful that I found your site!

      2. Hello Andrea! Thank you so much for taking the time to report back. I’m so glad it worked out well with the reduced amount of sugar. This is never going to be a ‘healthy’ cake (!!) but no harm in reducing the sugar a little. I really hope your mom enjoys it!
        P.S. I also have this recipe, which actually is a ‘healthy’ cake. Just in case you’d like to try it some day too. You’d never know it’s healthy: https://scrummylane.com/30-minute-healthy-chocolate-cake/

      I used Dutch process cocoa, 1.5 cups sugar, and cake flour instead of regular and it was perfect!!!!! I personally can’t imagine it without Dutch process!

      1. That’s good to know, Lucy. In the UK and Australia Dutch process isn’t so much of ‘a thing’ but it’s really helpful to know it works really well with it. Thank you for the feedback and I’m so glad you enjoyed the recipe! Mmm!

    I haven’t used a spring form pan in along time and have three brand new Teflon ones that I’ve had probably ten years and I’m wondering if you put yours in water just like making cheese cake? Although, I have it almost ready to go in the springform Pan! Idk how soon you’ll answer! 🤣

      1. I didn’t put it in water like you do cheesecake and it turned out great. I used special dark chocolate cocoa, it needed a bit more sugar with that cocoa and some salt. But it was soooo good anyway.

  10. Hi
    After adding all the ingredients and mixing I’ve got lumps, is that normal? Thanks

  11. I like the idea of serving it warm but I would like to make it a day in advance. What would you say is the best way to warm it up?

    1. Hi Jennie! Apologies for the late reply – we’re in the process of moving so things have slowed down a bit this week. I hope you either found a solution to this or you’re still game to try the recipe. I’d warm up individual pieces in the microwave (or oven if you don’t have one) but only for a very short time. Start with about 15 seconds per piece in the microwave. That will warm it up without it melting everywhere. Enjoy!

      1. Hi, I tried microwaving it for 15 secs for one slice as per your suggestion and it was still very tasty but had unfortunately lost a lot of its squidge. Maybe if I try undercooking it in the first place …
        Hope the move went ok!

      2. Ah really? Yes you could try slightly underbaking because it will harden in the fridge enough for you to cut it into slices and then microwave. Alternatively you could heat it slightly in an oven instead. Might be easier to keep an eye on than in the microwave?

    I’ve made this twice in two weeks. I cooked it for 18 minutes and it turned out perfectly. Added one tablespoon of coffee to enhance the cocoa flavor. My family’s new “sweet treat”….thanks for sharing!

    1. Hi Holly! Thanks so much for reporting back. It’s so good to hear it worked out perfectly for you first time. Sometimes it does and other times it needs a little bit of refining depending on your oven. I like your idea of adding coffee. Yum!

  13. Thanks for sharing and I’d like to try it. We are hosting 10 adults. I’m a little confused with the serving size. How many people will 1 cake serve if using the standard ingredients in the recipe? Would I need to make 2 cakes for 10 adults? Thank you.

    1. Hi Jimmy! So glad you’re thinking of making this. One cake will be enough for 10 people as it’s very rich. Serve dusted with some cocoa or icing sugar and with a bit of cream or ice cream, and berries if you like, and it’ll be quite enough for everyone 🙂

  14. I’m trying to cut my intake of sugar, is it possible to use stevia/truvia instead?

    1. Hi Jordan! I’ve never tried doing this, but I don’t think it would work as this recipe relies on the sugar for the texture. What you can do is reduce the amount of sugar in the recipe by around 25%. You could also try using coconut sugar or raw/organic sugar. It’s still sugar of course, but debatably a little healthier 😉 Overall, this recipe probably isn’t for you if you’re trying to watch your sugar intake (although I only ever serve small pieces!). I also have this recipe for a 30-minute healthy chocolate cake which you may enjoy better (maple syrup not sugar). It also gets excellent reviews!

  15. Another variation of this is that we also sometimes use licorice powder, added together with the kakao powder, in kladdkaka recipes.

  16. One recipe says to use eggs but the other recipe doesn’t say eggs. So do you add eggs or not?

    1. Hi Simona! Scroll down to the bottom and you’ll find the recipe in its on special box. That’s the recipe you want to be following. There are definitely eggs in it. Good luck. This is a great dessert for entertaining!

  17. This is not the time to cut back on the salt, half a tsp is minimum. Please don’t leave the kladdkaka in the oven for more than 15, maximum 17 minutes. The center is supposed to be almost liquid. And you have to leave it in the form, it will not work trying to get it out before it has set. Put the kladdkaka in the refrigerator, and get thy glorious reward the next day, with a dense, sticky chocolate dream. Serve with whipped cream and maybe som fresh raspberries or other sour berries as a contrast. /a swede

    1. Thanks so much for the tips, Nina. There’s definitely sometimes a bit of a learning curve to this cake. I agree that it’s really good the next day! Tastes like fudge. Mmmm, making me hungry!

      1. 5 stars
        You’re welcome, and thanks for sharing the recipe and the beautiful pictures!

        The great think about kladdkaka, is that you can adjust the recipe and add whatever you have at hand, here’s some more tips I’ve tried with yummy results: Chopped hazelnuts/walnuts on top, crushed candy cane pieces in the batter, warm peanut butter slightly to make it liquid and drizzle in the batter in a spiral from center and out. Or you could leave out the cacao and make a white sticky cake, +/- lemon peel or saffron (the saffron one is delicious served with lingon berries at Christmas). The white cakes need a bit more time in the oven. Also, I have experimented with the vanilla, I find vanillin in vanilla sugar a better option compared to pure vanilla extract, since you get a cleaner and stronger vanilla taste, which is needed to cut through the dense flavored cake.

      2. Oh wow Nina you truly are a kladdkaka expert! Thank you so much for the extra tips. I especially like the idea of trying it with white chocolate, although I can imagine the cooking time could be very different. I also love the idea of adding peanut butter swirls. 🙂

      3. Can I ask what type of sugar you use I’m going to make this today. Thank you

      4. Hi Lisa! I hope this message reaches you in time! It’s just ordinary white sugar. Caster sugar would work too. I think I’ve even used organic raw sugar successfully. So you shouldn’t have a problem, whichever sugar you use. Good luck! 🙂

      5. Hi Helen, thank you. I used caster sugar but it worked really well and went down a treat yesterday. Such an easy recipe! Absolutely delicious 😋
