To prevent the cake pops from sticking to the mold, grease it with cooking spray or butter before adding the batter.
Refrain from filling the mold all the way, as this will prevent the cake pops from expanding too much and losing their shape. Fill the mold about 2/3 to 3/4 full for the best results.
Before removing the cake pops from the mold, let them cool completely. This will make it easier to remove them and prevent them from breaking.
