Method
Baking Steps
Preheat your oven to 350°F (175°C) and prepare two 9-inch round cake pans.
Sift together the flour, cocoa powder, baking powder, baking soda, and salt.
Beat the egg yolks with half of the granulated sugar until pale and thick.
Stir in the vegetable oil and vanilla extract until well combined.
Gradually add the dry mixture and boiling water to the egg yolk mixture, mixing until smooth.
Beat the egg whites in a separate bowl until soft peaks form, then gradually add the remaining sugar until stiff peaks form.
Fold the whipped egg whites into the chocolate batter gently.
Divide the batter evenly between the prepared cake pans.
Bake for 25–30 minutes, or until a toothpick comes out clean.
Cool the cakes in the pans for about 10 minutes before transferring to a wire rack.
Frost your cooled cakes with chocolate frosting or serve with whipped cream and berries.
Slice and savor your delicious chocolate sponge cake.

For an added touch, top with fresh berries for a burst of flavor.
