Ingredients
Method
Batter and topping
- Beat the eggs with the sugar in a bowl using a mixer until light and fluffy. Add the flour with the baking powder and stir to combine.
- Divide the batter in half: stir the lemon zest into one half and the cocoa powder into the other. You now have two batters.
- For the topping, stir the mascarpone, sugar and eggs in a separate bowl until smooth.

Assembly and baking
- Pour the batters into the pan in layers, alternating with berries: chocolate batter first, then currants, the lemon batter, currants again - and the mascarpone topping last.

- Bake in an oven preheated to 180 °C (350 °F) until done - mine took an hour.
- Let the cake cool completely before serving. Enjoy!

Notes
A fully cooled cake slices much more neatly - the mascarpone layer sets as it cools.
