Method
Preparation
- Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper, dusting it with cocoa powder.
- In a bowl, sift together the flour, cocoa powder, baking powder, and salt.
- In another bowl, beat the egg yolks and half of the sugar until pale. Stir in the oil, buttermilk, vanilla, and espresso powder.
- Add the dry mixture to the wet ingredients until combined.
- Whip the egg whites to soft peaks, gradually add the remaining sugar, and beat to stiff peaks. Fold into the batter.
- Spread the batter in the prepared baking sheet and bake for 12-15 minutes until springy.
Rolling the Cake
- Invert the cake onto a clean towel and roll it up tightly. Allow cooling.
Making the Filling
- Whip the heavy cream with confectioners' sugar and vanilla until soft peaks form; fold in marshmallow creme if using.
- Unroll the cooled cake, spread with whipped cream filling, and roll it back up.
Preparing the Ganache
- For ganache, heat heavy cream and pour over chopped chocolate and corn syrup, stirring until smooth.
Serving
- Serve by slicing and drizzling with ganache, optionally pairing with berries or ice cream.
Notes
This cake is best served chilled, with a drizzle of rich chocolate ganache on top. Add fresh berries on the side for a colorful touch. Store the cake tightly wrapped in plastic wrap in the refrigerator for up to 3-4 days.
