You can use any cake mix and frosting flavor you like. For a healthier option, try using yogurt instead of frosting. Experiment with different coatings such as white chocolate or colored candy melts, and try adding flavor extracts for an extra kick (e.g., peppermint or almond). Store in an airtight container at room temperature for up to 3 days, or in the fridge for up to a week. They can also be frozen for later enjoyment.
