Mix white cake mix, egg whites, oil, water and sour cream for three to four minutes on medium speed. Split cake batter into three equal amounts, adding red and blue food coloring to two of the portions. Coat three, 4 x 9-inch bread pans with cooking spray and lightly flour the bottoms. Add the three batters to the pans and bake at 350 degrees F for 18-23 minutes. Allow them to cool and remove from pans.
Guaranteed to be the most POPular dessert at your 4th of July party, these Pop Rocks-filled treats will surprise everyone's taste buds. Made with a dense, sponge-cake-like recipe, the colored cakes stack nicely and hold together with just a dab of frosting.
Put a portion of the red cake plugs back into the bottoms of the red cake circles. Pipe a line of frosting around the centers of the red and white cake circles. Stack the white cakes on top of the red cakes and the blue cakes on top of the white cakes.
For maximum popping potential, pour the Pop Rocks into the cake centers no earlier than one hour before serving. The moisture in the cakes will cause the Pop Rocks to slightly snap and crackle on their own. In fact, they make a great sizzling sound on the plate. But after about four hours the Pop Rocks lose most of their popping power, so plan accordingly. Yields 10-14 cakes.
