Preparation
- Preheat your oven to 375°F (190°C). Line a jelly roll pan with foil and grease it.
- Beat egg whites until soft peaks form, then gradually add 1/2 cup granulated sugar until stiff peaks form.
- In another bowl, mix egg yolks and vanilla extract, adding the remaining 1/2 cup sugar until smooth.
- Combine flour, cocoa powder, baking powder, baking soda, and salt in a bowl; add to the yolk mixture alternately with water.
- Fold the beaten egg whites into the chocolate mixture gently to maintain volume.
- Spread the batter in the prepared pan and bake for 12-15 minutes, until the top springs back.
- Invert the cake onto a powdered sugar sprinkled towel and roll it up to cool.
- Whip butter, powdered sugar, vanilla extract, and marshmallow fluff until smooth; add milk if needed.
- Unroll the cooled cake, spread filling, and re-roll it without the towel; wrap in plastic wrap.
- Melt chocolate chips, butter, cocoa powder, and milk together, then stir in powdered sugar for glaze.
- Pour glaze over the chilled cake on a wire rack and spread evenly.
- Chill the glazed cake for 30 minutes before slicing and serving.

Notes
For best results, ensure egg whites are free of yolk and fold gently to maintain volume.
