Step 1

Prepare the cake mix in a 9x13 pan as per the instructions on the box. Bake until golden and a toothpick inserted in the center comes out with only a few crumbs (not wet batter). Allow the cake to cool for 15 minutes after removing it from the oven.

Step 2

In a medium-sized bowl, combine the strawberry jello mix with 1 cup of boiling water. Whisk for 2 minutes, or until the powder is completely dissolved. Whisk in 1/2 cup of cold water and set aside.

Step 3

Repeat the process in a second bowl to prepare the lime jello.

Step 4

Using the handle of a wooden spoon, poke holes throughout the top of the cake.

Step 5

Spoon or pour the prepared jello mixtures into each of the holes, alternating the colors as you go.

Step 6

Refrigerate the cake for at least 3 hours to allow the jello to set.

Step 7

Frost the cake and top with sprinkles before slicing and serving.
