He did the Mash, the Monster Mash, it was a graveyard smash! The Creepy Monster mash whoopi pies may not be part of cheesy song lyrics, but they are a great Halloween snack!
Moist and colorful cakes sandwiched between whipped buttercream frosting and then decorated with the crazy monster candy eyes! I had a lot of fun making these whoopi pies and can't wait to hand them out to the neighborhood kiddos later! My eldest gave me his approval yesterday.

Tips and tricks
This recipe is pretty easy to make and super kid friendly.
- A spoon or piping bag can be used to put the batter onto the baking sheets. I have done it with both. This time around I used a spoon and a wooden skewer to help make the batter a more round circle.
- Adding the monster candy eyes soon after the whoopi pies have cooled will allow them to stick better since they are still somewhat warm.
Substitutions and variations
- Use different flavored cake mixes, but be sure they are dark as the colors will not be as vibrants when making the monsters
- Use unsalted butter if you don't have salted, and add an extra pinch of salt in there
- Different flavors of buttercream can be used to change up the flavor
- Make larger whoopi pies to create larger monsters
