To make this delicious all-in-one lemon mascarpone cake, just toss everything together, pour into two pans and bake. Then sandwich together with a ridiculously easy 2-ingredient lemon mascarpone cream. It’s classic Victoria sponge meets lemon cake – perfect for a special occasion or just a simple afternoon tea.
Why this is a great layer cake
Is there such thing as a layer cake snob?
I don’t mind if it doesn’t look perfect (rustic rules), but I want it to taste as good as it sounds. Like this really good, really simple chocolate orange cake. Or this peanut butter, banana and chocolate chip cake which hits the spot every time.
This makes the cut because:
- It’s essentially the most basic vanilla cake recipe (otherwise known as Victoria Sponge). Traditionally you make it with equal amounts of butter, sugar and flour. Except I like to reduce the sugar just a little… 😉
- It’s what’s called an ‘all-in-one’ cake. In other words, throw everything into the bowl and mix! No creaming of butter and sugar first, I promise. Just a bit of careful mixing either in a food processor (= super easy) or with a hand-held whisk (=pretty easy too).
- It’s sandwiched together with a mascarpone and lemon curd cream. Just those two delicious ingredients. How easy is that? Also great for people who aren’t fans of a fresh cream filling (like myself). And no cream whipping necessary!
In summary, this must be the easiest Victoria sponge cake recipe. Perfect if you aren’t into fussy baking recipes, but you still want an impressive and crowd pleasing layer cake.
What’s a Victoria sponge? (just in case you aren’t British and were wondering) It’s an airy vanilla cake traditionally filled with fresh cream and jam.
This lemon mascarpone cake has all the yummy-ness but is even easier to make.
About the ingredients
For the easy cake batter
Butter: Use real, unsalted good quality butter. Get it out of the fridge a little while before you’re ready to bake your cake. If you live in a hot country like I do, it’s a fine balance. You want soft but not melted butter!
Sugar: Fine/Caster sugar is best. But I sometimes use regular sugar, and the cake still turns out fine.
Eggs: You need 4 for this cake. I like to use the best quality I can get!
Vanilla: I usually use a teaspoon of vanilla essence but if you want to be a bit fancy pants, you can use a real vanilla pod instead.
Self-raising flour: Just a reminder that self-rising flour (US) is not the same as self-raising flour. If you’re in the USA and using self-rising flour, add an extra teaspoon of baking powder.
Alternatively you can use all-purpose/plain flour and add 2 teaspoons baking powder.
Baking powder: Just a teaspoon for extra ‘oomph’!
Milk: You only need a few tablespoons. Add it little by little until you have the right consistency. The batter should easily drop off a wooden spoon without being too runny.
For the lemon mascarpone cream and topping
Mascarpone cheese: Here in Australia mascarpone usually comes in 250 gram tubs (a UK/Aussie cup). The amount doesn’t have to be exact though so don’t buy another tub just to make it up to 250 grams.
Lemon curd: Here’s where the magic happens. All you have to do is roughly mix a few tablespoons of lemon curd into the mascarpone cheese. Voila – you have a stupidly simple (but amazing tasting) cake filling that’s a bit different to ‘just’ fresh cream.
Icing sugar: No fussy toppings here. Just sprinkle a little icing sugar over the top of the cake to serve. Do this just before serving so it doesn’t have time to dissolve into the cake.
How to make it
In a food processor
Steps 1 and 2: I usually start by pulsing the softened butter with the sugar for a few seconds until well combined.
Strictly speaking you could throw all the batter ingredients in together, but I like to make sure the butter is well mixed in before adding the flour. This avoids overmixing and making your cake too dense.
Steps 3 and 4: Throw in all of the other batter ingredients, including the flour, and process for a few seconds. Just until well combined. As with any cake, you don’t want to overmix.
Steps 5 and 6: Divide the batter roughly in two and scrape into two prepared cake pans. Smooth down with a spatula and bake for about 25 minutes.
With a hand-held whisk
There isn’t too much difference in the method. Just use a hand-held whisk to combine the softened butter and sugar first. Then briefly whisk in the other batter ingredients.
The only difference is that there’s no need for the extra teaspoon of baking powder if you mix by hand. I have to admit that I don’t know why!
Step 7: Mix a few tablespoons of lemon curd into some mascarpone cheese.
Step 8: Spread it all over one of the cakes. Don’t be shy!
Step 9: Dollop more lemon curd over the top. Again, don’t be shy!
Step 10: Place the second cake over the top and push down a little. Some lemon curd might drip down the sides, but this adds to the rustic effect!
Last but not least, sprinkle over a bit of icing sugar. Then serve and impress with your simple but classy cake.
- It’s best to use slightly softened butter so that it combines with the sugar easily. Just try to remember to get it out of the fridge shortly before you’re ready to make the batter.
- Whether you make the batter with a hand-held whisk or food processor (or even a stand mixer), only mix until the ingredients are well combined. If you overmix your cake can end up a bit tougher and heavier than it should be.
- When you think the cakes are cooked, quickly flip them over and check they’re cooked on the bottom. If they aren’t quite done, pop them back into the oven for a few more minutes.
Absolutely! Just follow the instructions for the hand-held whisk method. Again, don’t overmix.
Actually, no. Self-raising flour contains more baking powder. You can use self-rising flour – just add an extra teaspoon of baking powder. Or just use plain/all-purpose flour and add a teaspoon of baking powder per cup.
I have to be honest. This cake is best eaten the same day. If there are any leftovers, you’ll have to store it in the fridge because of the mascarpone cheese filling. But if you cover it well, the cake shouldn’t dry out overnight. Take it out of the fridge a while before serving to let it come back to room temperature and it’ll still be very tasty.
You can. Wrap the cakes really well individually and make and add the filling when you’re ready to eat the cake. You can also freeze it after you’ve added the filling – either whole or in separate pieces. Just wrap well and freeze for up to 3 months. Defrost and enjoy!
Alternative ways to make this cake
If you wanted to you could quite easily make this very simple lemon layer cake a bit fancier.
Here are some ideas:
- Add some blueberries into the cake batter. You’ll end up with a simple lemon blueberry cake.
- At the last minute, top the cake with some freshly sliced strawberries.
- Spoon passionfruit pulp over the lemon mascarpone cream instead of extra lemon curd. Either fresh passionfruit or canned works.
- Similar to the above! There is also a blueberry passionfruit version of this cake that will blow your mind. Full instructions with the recipe below!
- Be really fancy. Make a little extra lemon mascarpone cream and pipe little swirls around the edge of the top of the cake. Leave like that or top the cream with extra lemon curd or fruit.
- Make extra filling for the top and sides of the cake. Decorate with fruit.
