Instructions

Step 1: Bake the Cake

Prepare and bake the white cake according to the package directions. Allow the cake to cool for at least 30 minutes.

Step 2: Poke the Holes

Using the handle of a wooden spoon, poke holes all over the cake about 1/2 to 3/4 of the way deep. Be careful not to poke completely through the cake.

Step 3: Prepare the Red Jello

In a small bowl or large measuring cup, dissolve the red Jello in 1 cup of boiling water. Stir until completely dissolved, then add 1/2 cup cold water.

Step 4: Prepare the Blue Jello

In another bowl or measuring cup, dissolve the blue Jello in 1 cup of boiling water. Stir until dissolved, then add 1/2 cup cold water.

Step 5: Fill the Cake

Carefully pour the red and blue Jello into alternating holes throughout the cake. Avoid mixing the colors together so the cake keeps its patriotic red and blue pattern.

Step 6: Chill

Cover the cake and refrigerate for at least 2 hours to allow the gelatin to fully set.

Step 7: Make the Topping

In a medium bowl, whisk together the whipped topping and powdered sugar until smooth and fluffy.

Step 8: Frost & Decorate

Spread the whipped topping evenly over the chilled cake and top with festive sprinkles.

Step 9: Serve & Enjoy

Slice and serve cold for a fun, colorful summer dessert perfect for holidays and parties.
