Prepare and bake the cake mix according to the boxed directions.
Immediately after taking the cake out of the oven, pour the hot cake into the bowl of a stand mixer. (Do not over cook the cake! if so, it will have a harder time coming together)
Add in the powdered sugar and vanilla extract and using the paddle attachment, mix on low speed until a dough forms that can be pressed together into a ball.
Portion out the dough and press into a ball in the palm of your hands or with a cake pop press.
Place the cake balls on a cookie sheet and then into the freezer to chill.
Melt the colormelts.
Once the chocolate coating is melted, remove the cake balls from the freezer.
Dip each lollipop stick into the candy melt and then press the stick into the center of each cake ball. This will help avoid the cake pop falling off of the stick.
Return to the fridge or freezer to help speed up the process of the stick and chocolate setting.
Once the chocolate is set on the sucker sticks, pour the remaining melted candy melt into a tall, skinny jar or glass.
Dip the cake pops one by one in the candy melt and gently shake the cake pop to remove any excess melted chocolate. Tip right side up and add sprinkles, if desired.
Allow the candy melt to set while the cake pop is right side up, you can poke holes into a cardboard box or foam block to help them stand up straight to dry, if desired.
Serve as is or package up individually in bags with ribbon if desired.
Enjoy! Store at room temp for up to 3 days.
