Seven-Layer Soda Pop Rocks Cake



Seven-Layer Soda Pop Rocks Cake

We tested the cake using Betty Crocker Super Moist White Cake Mix and 9-inch cake pans.

4 (16.25-ounce) boxes white cake mix (enough for 8 cake layers)

5 cups 7-Up or similar soda, divided, to substitute for the water in the cake mix

11/3 cups vegetable oil, divided, or as needed to prepare boxed cake mix

12 egg whites, divided, or as needed to prepare boxed cake mix

Assorted food coloring

About 20 cups (10 pounds) prepared white frosting

24 packets assorted Pop Rocks

Candy wax soda bottles, for decorating

Skewers, for decorating

Soda straws, for decorating

Working in batches if necessary, prepare the boxed cake mix according to package directions, substituting soda for the amount of water given and incorporating the vegetable oil and egg whites as instructed (cake mix ingredients may vary slightly by brand).

Divide the batter among prepared 8- or 9-inch cake pans (you will end up with one extra layer of cake not needed for this recipe). Add food coloring to enhance each of the seven layers separately with bright color: turquoise, pink, yellow, orange, purple, aqua, lime. Bake according to package directions.

When the layers are cool, begin assembling the final cake. Place the first layer on a cake stand or platter and top with a layer of frosting. Sprinkle over a packet of Pop Rocks. Top with a second layer of cake, and repeat until the cake is seven layers. As the layers are built, the cake will become top-heavy and may start to slide and/or fall; to help stabilize it, run skewers or cake dowels (available at cake and cooking supply stores) through the layers.

Frost the outside of the layers and sprinkle over the remaining Pop Rocks to decorate. (The Pop Rocks will become sticky shortly after the package is opened and if handled. To decorate the sides, it might be easiest to empty each package onto a sheet of paper, then curl the paper and blow the Pop Rocks onto the side of the cake.)

To assemble the decorations, place the wax soda bottles on skewers and cover each skewer with a soda straw. Arrange the bottle-topped skewers on top of the cake. Makes 30 servings.
