Prep oven. Preheat your oven to 350 degrees.

Line cupcake pan. Place 24 cupcake liners in you cupcake pans.

Make batter. In a medium mixing bowl combine your cake mix, water, oil and eggs. Stir until well combined. Pour the cake batter into the baking dish.

Bake cake layer. Bake the cupcakes for 15-20 minutes until a toothpick inserted comes out clean.

Cool cakes. Set the cupcake aside to cool. Once cool remove them from their liners.

Make the base layer. Put a cupcake into each cauldron, you will have to squish them down into the cauldrons and make sure you leave a little room for the pudding.

Make Pudding. In a medium bowl combine the instant pudding and milk. Whisk until smooth. Add a few drops of neon green food coloring and stir together until desired green shade.

Make the second layer. Top off each cauldron with a spoonful of pudding, careful not to overfill.

Make Rice Krispies. In a large pot melt your butter and marshmallows together. Stir in a few drops of green food coloring until you get the green color you like.  Make it a little darker than you want because it will lighten when you add the rice krispies.

Assemble the cauldron. Working quickly spoon rice krispies on top of each cauldron. If it drips down the side, that’s okay we are going for a bubbling cauldron look. Top with sprinkles.
