Ingredients
Directions
Prepare the pan and oven
Heat oven to 375°F.
Line a 15-1/2x10-1/2x1-inch jelly-roll pan with foil; generously grease foil.
Make the batter
Beat egg whites in a large bowl until soft peaks form; gradually add 1/2 cup sugar, a tablespoon at a time, beating on high speed of mixer until stiff peaks form.
Beat egg yolks and vanilla in a medium bowl on high speed about 3 minutes; gradually add remaining 1/3 cup sugar. Continue beating 2 additional minutes or until mixture is thick and lemon-colored.
Stir together flour, cocoa, baking powder, baking soda, and salt.
Gently fold the dry mixture into the egg yolk mixture alternately with water until smooth.
Gradually fold the chocolate mixture into the egg whites.
Spread batter evenly into prepared pan.
Bake and roll
Bake 12 to 15 minutes or until top springs back when touched lightly in center.
Immediately loosen cake from edges of pan.
Invert cake onto a clean linen towel sprinkled with powdered sugar.
Carefully peel off foil.
Immediately roll cake in towel starting from narrow end.
Place rolled cake on wire rack.
Cool completely.
Fill and finish
Prepare white cream filling.
Unroll cake.
Remove towel.
Spread filling over cake.
Reroll cake.
Spread chocolate glaze over top and sides.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites and beaten yolks provide the airy structure that lifts the sponge.
- Sugar
- Sweetens the cake and stabilizes the whipped egg whites into a firm foam.
- All-purpose flour
- Provides the starch and gluten that set the sponge's crumb once baked.
- Hershey's cocoa
- Gives the sponge its chocolate flavor and dark color.
- Baking powder
- Releases gas during baking to help the cake rise.
- Baking soda
- Reacts with acidic components to help the cake rise and brown.
The step that matters
Folding the batter. Whites hold the cake's lift, so folding gently and not stirring keeps the foam from collapsing and the sponge from turning dense and flat.
Flavor stand-ins for the cocoa
How well each one fits the dish's main ingredients (egg, sugar, vanilla, flour):

- Chestnutbetter flavor fit
- Macadamia nutbetter flavor fit
- Cocoathe original
Fit is the average pairing score against egg, sugar, vanilla, flour. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
