Prepare the strawberry and chocolate cake layers according to the recipe instructions. Let each cool completely.
In a large bowl, beat the butter, vanilla, powdered sugar, and 2 tablespoons heavy cream until light and fluffy. If needed, add an additional 1-2 tablespoons cream to achieve the proper texture.
Crumble the strawberry cake into a large bowl. Scoop half of the buttercream into the crumbs and, using clean hands or a large wooden spoon, stir together until the cake easily sticks together when rolled. Gather 1 tablespoon sized mounds of dough and form into balls. Set onto a large parchment-lined baking sheet.
Repeat the above process with the chocolate cake and remaining buttercream. Set the balls in the fridge for at least an hour, or the freezer for 30 minutes.
In a glass measuring cup or heat-safe bowl deep enough to dunk the cake pops, microwave half of the candy melts for 1 minute. Stir, then heat an additional 20-30 seconds until completely melted.
Dip the tip of a cake pop stick into the candy melt, then slide about halfway into a cake pop. Stand the cake pops in a large piece of styrofoam or a cake pop stand if you have one. Repeat with half of the remaining pops.
Dip a cake pop completely into the candy melt, let excess drip back into the bowl or glass, then stand back up in the styrofoam. Sprinkle with your choice of decorative jimmies. I left a few plain white to drizzle with the pink candy melts later.
If the cake pops are starting to feel too soft from sitting out, place the tray back into the refrigerator for 10 minutes to resolidify.
When the white candy melts are used up, microwave the remaining melts along with 1-2 drops of red or pink food dye. Repeat the decorating process with the remaining cake pops, sprinkles, and doodads. Have fun with it!
