In a small bowl, mix together all the frosting ingredients until light and fluffy.

Remove the edges from the baked cake to avoid any crust in the cakesicles.

Break up the cake into large pieces or crumbles in a large bowl.

Add the frosting, starting with 2 tablespoons, and mix until combined.

Test the mixture to see if it holds a ball shape when squeezed together; add more frosting if too dry.

Set aside the cake mixture once it is soft and moldable.

Melt the candy melts or chocolate in the microwave in 15-second increments, stirring in between.

Add about 1 ? tablespoons of melted candy to each mold cavity and spread evenly.

Insert a popsicle stick into each cavity to create an opening; chill the molds in the fridge for 15-20 minutes or until set.

Gently press the cake mixture into each mold, leaving a 1/16" gap at the top.

Smooth out the top of the cake with your fingers or the back of a spoon.

Add a dollop of melted coating on top of the cake and smooth it out.

Use a bench scraper or the back of a flat knife to scrape off excess coating from the top.

Insert the popsicle sticks into the openings at a slight downward angle for secure fit.

Chill for 15-20 minutes or until set.

To remove the cakesicles, stretch the sides of the mold away from the cakesicle and carefully push underneath to pop it out.

Use a sharp knife to trim any excess coating on the edges if necessary.

Decorate as desired with drizzled chocolate, candy melts, sprinkles, luster dust, etc.
