Mix the cake mix with the eggs, pudding mix, and milk.
Then add a little bit of the batter at a time to a pastry bag; this will make for easier filling of the cooking reservoirs in the cake pop maker.
Heat up the cake pop maker, and wait for the green light to show that it's ready.
Give a light coating of cooking spray to each reservoir in the cake pop maker; then fill each cooking reservoir with about 1 tablespoon of cake batter, trying not to overfill. If you overfill, instead of a round cake pop “planet,” you might end up with “Saturn.” I love using the cake pop maker because it shapes the cake pops for you, as long as you fill the reservoirs appropriately.
Lower the lid on the cake pop maker, latching it shut. Now it's just a waiting game, about 4-6 minutes per batch of cake pops. Definitely use a pot holder to lift the lid because it can be quite hot to the touch. When done, you should have nice, round cake pops.
The cake pop maker comes with a fork, so you can easily remove the cake pops and place them in a spot to cool.
