“Delicious cake. Friends were impressed. Better than using butter icing. I mixed the lemon curd with the mascarpone and it worked out fine – very light sponge. I will definitely do this again maybe with different fruit. Ideal for parties and any event really!” (Sue)
About the ingredients
The full ingredient list and amounts are in the recipe card below. Here’s a concise overview.
For the cake batter
- Butter: Use good-quality unsalted butter, softened to room temperature so it blends easily.
- Sugar: Fine or caster sugar works best, though regular granulated sugar is fine too.
- Eggs: Four large eggs give the sponge structure and lift.
- Vanilla: A teaspoon of good vanilla extract enhances flavour.
- Self-raising flour: If you use plain/all-purpose flour, add baking powder (about 2 tsp per cup) to replace self-raising flour.
- Milk: A few tablespoons to adjust consistency; add gradually until the batter drops from a spoon but isn’t runny.
Optional: Add lemon zest to the batter for extra citrus brightness.
For the lemon mascarpone cream and topping
- Mascarpone cheese: A smooth Italian cream cheese available in most supermarkets; it makes a rich yet light filling.
- Lemon curd: Stir a few tablespoons into the mascarpone for a bright, tangy filling. Store-bought lemon curd keeps the recipe quick, but homemade works equally well if you prefer.
- Confectioners’ sugar: A light dusting just before serving adds a pretty finish—don’t powder too early or it will dissolve.
What’s mascarpone cheese?
Mascarpone is an Italian cream cheese made from fresh cream. It’s smooth, mildly sweet and very rich—commonly used in tiramisu and in creamy dessert fillings. In this cake it creates a luxuriously soft filling when blended with lemon curd.
How to make lemon mascarpone cake
You can make the batter in a food processor or with a hand-held mixer. Both are straightforward—just avoid overmixing.
Food processor method
Pulse the softened butter with the sugar briefly until combined. Add the vanilla, eggs, flour, optional lemon zest and baking powder, then pulse until just smooth. Scrape the batter into two prepared pans, level the tops and bake for about 25 minutes.
Hand-held whisk method
Cream the softened butter and sugar with a hand mixer, then whisk in the remaining ingredients until just combined. When whisking by hand you’ll incorporate a little more air, so you can omit the extra teaspoon of baking powder if you prefer.
After baking and cooling, mix about 4 tablespoons of lemon curd into the mascarpone to make the filling. Spread generously over one sponge, dollop extra lemon curd on top of the cream, then sandwich the second sponge on top. A little drip down the sides is part of the cake’s rustic charm.
Finish with a light dusting of icing sugar just before serving and enjoy a simple yet impressive cake.
Helen’s Top Tips
- Use slightly softened butter so it blends quickly with the sugar—take it out of the fridge about 30–60 minutes before you start, depending on room temperature.
- Mix only until combined: Whether using a food processor or mixer, stop as soon as the batter is smooth to avoid a dense cake.
- Check the underside: If the skewer looks clean but you’re unsure, lift a cake to confirm the bottom is cooked; return to the oven a few minutes if needed.
FAQ
Yes—use the same steps as the hand-held whisk method and be careful not to overmix.
Eat the cake the same day for best texture and flavour. If you keep leftovers, store covered in the refrigerator to protect the mascarpone filling. Bring to room temperature before serving for the best taste.
Yes. Wrap cake layers well and freeze, then assemble with filling when ready to serve. You can also freeze the assembled cake or slices for up to three months—wrap tightly and thaw before serving.
Whipped cream is the easiest substitute; crème fraîche also makes a similar, slightly tangy filling.
Alternative ways to make it

Measure notes: Cup measurements in this recipe use US cup sizes. If using larger AU/UK cups, reduce the flour and sugar slightly as noted in the recipe card.
