Ingredients
Method
Preheat the oven.
- Set your oven to 350°F (175°C). Line a baking sheet with parchment paper.
Make the sponge batter.
- In a mixing bowl, beat the egg yolks, sugar, and vanilla until pale and creamy.
- Gently fold in the flour and cornstarch until smooth. Don’t overmix.
Make the meringue.
- In a clean bowl, beat the egg whites until soft peaks form. Gradually add sugar, one spoon at a time, and continue beating until the meringue is glossy and holds firm peaks.
Pipe the layers.
- Spoon both batters into separate piping bags. On the prepared baking sheet, pipe alternating stripes of sponge and meringue next to each other — like zebra stripes. They should touch lightly but not overlap.
Bake.
- Bake for 20 minutes, or until the sponge is golden and the meringue is crisp on top.
- Let it cool completely on a rack.
Prepare the coffee cream.
- In a bowl, whip the heavy cream, instant coffee, and powdered sugar together until soft peaks form. Taste and adjust the coffee flavor if you like it stronger.
Assemble the cake.
- Cut the baked sheet in half lengthwise. Spread the coffee cream evenly over one half. Gently place the second half on top, meringue side up.
Chill and serve.
- Dust with powdered sugar and chill for at least 1 hour before serving.
- Slice with a sharp knife and enjoy!
Notes
- Use room temperature eggs — they whip up better and give a lighter texture.
- You can swap the coffee filling for vanilla or berry cream if you prefer something milder.
- The cake keeps well in the fridge for up to 2 days. Cover it lightly so it doesn’t dry out.
- For the neatest slices, use a sharp serrated knife and clean it after each cut.
