Preheat the oven to 350 degrees and line a 12-count muffin tin with the black cupcake liners. Combine the chocolate cake mix, eggs, vegetable oil and water.
Fill each muffin well about ⅔ full. Bake for 18-20 minutes. Insert a toothpick into the cupcakes around 18 minutes, if it comes out clean the cupcakes are done.
Remove from the oven and let cool.
Place the mold in the fridge for 2-3 hours or until set.
Once the Jell-O has set, remove from the fridge.
Now to Frost the Halloween Cupcakes.
Use a toothpick to apply a small amount of frosting on the back of the small candy eyes.
Give each Blobby/Slimer (2) eyes and place on top of the frosted cupcakes.
Repeat with each Halloween cupcake.
Notes
Use a silicone mold for the slime. This helps create a consistent, gooey shape that sits perfectly atop each cupcake.
Chill the slime before assembly. Refrigerating the slime ensures it holds its shape and adds a cool contrast to the cupcake.
Add candy eyes for a spooky touch. Placing candy eyes on the slime gives your cupcakes a playful, eerie character.
