Prepare and bake brownies as directed. Cool completely, then crumble into a bowl.

Mix in ¼ cup of frosting to create a moldable dough.

Melt candy melts or chocolate until smooth.

Spoon a layer into each cakesicle mold and use the back of a spoon or pastry brush to coat the bottom and sides.

Insert popsicle sticks and let chocolate set (refrigerate for 10-15 minutes).

Press brownie mixture into each mold over the hardened chocolate layer, leaving a little room at the top for sealing with chocolate.

Spoon more melted chocolate over the brownie layer to completely cover and seal the cakesicle.

Smooth the top and refrigerate again until set (about 15-20 minutes).

Once fully set, gently pop the cakesicles out of the mold.

Decorate as desired with chocolate drizzle, Halloween sprinkles, candy eyes, or themed candies.
