Preheat the oven to 350°F (175°C). Grease a baking pan or line it with parchment paper.

Prepare the cake mix according to package instructions, mixing in eggs and oil until smooth.

Pour into the pan and bake for about 30 minutes or until a toothpick comes out clean.

Allow the cake to cool completely on a wire rack.

Once cool, crumble the cake into fine pieces in a large bowl.

Mix in buttercream frosting until the mixture holds together like damp sand.

Form small balls from the mixture, about one inch in diameter, and place on a parchment-lined baking sheet.

Melt chocolate melts according to package instructions.

Dip each cake ball halfway into the melted chocolate before returning them to the baking sheet.

While the chocolate is still wet, sprinkle each pop with crushed cookie crumbs and insert a gummy worm into each pop.

Let set in the refrigerator for about an hour before serving.
