Start by gathering your cake pieces! (note: this can be from leftover cake trims, homemade cake, or store bought pound cake!) Line a plate or baking tray with parchment paper. In a large bowl, use your hands to crush your cake pieces into moist crumbs.
Add 1 tbsp of frosting to your cake crumbs (note: this can be leftover frosting from your last cake or store bought). Mix together with your hands. Continue adding 1 tbsp at a time until you achieve a slightly moist, playdough consistency.
Scoop 1 tbsp portions of cake dough and place on a baking tray.
Roll dough portions into balls and refrigerate for at least 30 minutes (or 15 min in the freezer).
Place your white chocolate wafers/candy melts in a small, deep bowl or glass measuring cup. Melt chocolate in the microwave (note: this is done in 15s increments until chocolate is fully melted).Add your popping candy and stir until all popping candy is coated.
Remove cake balls from the fridge.
Drop one cake truffle in the melted chocolate, cover completely, and remove using 2 forks (note: this will allow excess chocolate to drip off while you are removing the cake truffles).
Allow your cake truffles to cool in the fridge for an additional 15 minutes or until their surface is hard to the touch.
Enjoy your "pop"-tacular Cake Pop Truffles!!
