CHOCOLATE MARBLE CHIFFON CAKE
Combine ¼ cup unsweetened cocoa powder and 2 tablespoons packed dark brown sugar in small bowl, then stir in 3 tablespoons boiling water and mix until smooth. Follow recipe as directed, dividing batter equally into 2 separate bowls at end of step 2. Mix scant ½ cup batter from 1 bowl into cocoa mixture, then partially fold mixture back into same bowl (so that you have 1 bowl of white batter and one of chocolate batter). Sift 3 tablespoons flour over chocolate batter and continue to fold until just mixed. Pour half the white and then half the chocolate batter into the pan; repeat. Do not tap pan on counter before baking. Bake as directed.
