Storage: Keep finished pops in an airtight container in the fridge for up to 1 week. You can freeze the undipped cake balls for up to 3 months, or finished pops for up to 2 months (thaw in fridge before serving).
Swaps: Use chocolate cake mix + chocolate frosting for chocolate cake pops. For strawberry/birthday cake, use strawberry cake mix or add 3 tbsp strawberry jam to the vanilla crumb mixture. For gluten-free, use a 1:1 gluten-free vanilla cake mix (Cup4Cup or King Arthur work well).
Tips: Don't skip the freezer time – it's what prevents cracking. Thin your coating with coconut oil for a glossy, snappy shell. Use a tall glass for dipping to get an even coat. Tap your wrist, not the stick, to avoid losing the pop in the coating.
