To make this treat... follow the recipe for spongefon cake, using the jelly roll method (bottom of recipe).

To get the decorative strips on the cake: after making the cake batter, remove about 3 tbs of batter and mix in some food coloring. Pour the rest of the batter into a jelly roll pan. Fill a sandwich bag with the colored batter and cut a small hole in the bag. Pipe the colored batter into long strips on top of the batter already in the ban. Use a knife or toothpick to "drag" the lines together to create the pattern (if the colored batter is piped on horizontally then drag the toothpick vertically). Bake and fill/assemble as you would for any jelly roll.
