Mix all ingredients together, making sure your batter is fairly stiff, about the consistency of brownie batter. Do not add oil to the mixture.
When cake batter is ready, add a little bit 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 cooking reservoir in the cake pop maker; fill each reservoir with about 1 tablespoon of cake batter, trying not to overfill. Lower the lid on your cake pop maker, latching it shut. Then wait approximately 4-6 minutes per batch of cake balls.
Use a pot holder to lift the lid because it can be quite hot to the touch. Use the provided fork to lift each cake ball out of the maker and onto a place to cool.
Before decorating, place cake balls into the freezer for about 10 minutes.
To decorate your cake balls as Truffula Trees, use candy melts and cotton candy. Melt the candy melts according to the directions on the package. Then remove cake balls from the freezer, and start decorating.
Take a cake pop stick, dip it into the melted candy, and insert into the cake ball.
Then dip each cake pop into the melted candy, coating well and allowing excess candy to drip before placing upright.
Place each cake pop into a cake pop stand.
Wrap your cake pops in cotton candy before the candy coating dries.
Serve immediately after adding cotton candy and enjoy!
