- 1 and 1/2 teaspoons pure vanilla extract
- 1 teaspoon espresso powder (optional)
For the Vanilla Whipped Cream Filling:

Instructions
- Prepare your pan
Preheat oven to 350°F (177°C). Line a 10×15-inch jelly roll pan with parchment paper, leaving an overhang for easy removal. Lightly grease and dust with cocoa powder. - Mix dry ingredients
In a bowl, sift together the cake flour, cocoa powder, baking powder, and salt. Set aside. - Beat egg yolks and oil
In a large bowl, whisk the egg yolks with 1/2 cup (100g) sugar, vegetable oil, buttermilk, vanilla extract, and espresso powder (if using) until combined and slightly thickened. - Whip egg whites
In a separate, clean bowl, beat egg whites on medium speed until soft peaks form. Gradually add the remaining 1/4 cup (50g) sugar and continue beating until stiff, glossy peaks form. - Combine wet and dry
Add the dry ingredients to the egg yolk mixture and fold gently until just combined. - Fold in egg whites
Carefully fold the whipped egg whites into the batter in thirds, preserving as much air as possible. - Bake the sponge
Pour batter into the prepared pan and spread evenly. Bake 12-15 minutes or until the cake springs back when lightly touched. - Roll the cake while warm
Immediately after baking, sprinkle a clean kitchen towel with cocoa powder. Invert the cake onto the towel, peel off parchment, and roll the cake up in the towel from the short end. Cool completely rolled up. - Prepare whipped cream filling
Beat the heavy cream with sugar and vanilla until soft peaks form. If using marshmallow creme, fold it in gently. - Unroll and fill
Carefully unroll the cooled cake. Spread the whipped cream filling evenly over the cake, leaving a small border. - Re-roll the cake
Roll the cake back up without the towel, using the filling as glue. - Prepare chocolate topping
Heat cream until just simmering and pour over chopped chocolate. Let sit 1-2 minutes, then stir until smooth. Stir in corn syrup for shine if desired. - Glaze the cake roll
Pour or spread the chocolate topping over the rolled cake. Refrigerate at least 1 hour to set before slicing.
Notes
Use room temperature eggs for best volume when whipping whites.
Don’t overmix when folding in flour or egg whites to keep the sponge light.
Roll the cake while warm to prevent cracks.
For easier slicing, chill the cake after glazing to firm it up.
