Monster Cookie Skillet

Stop. Right now, go raid your kid’s Halloween candy stash and steal all of the peanut butter candy – I’m talking Reese’s Peanut Butter Cups, Reese’s Pieces, Peanut and Peanut Butter M&Ms, anything that is peanut butter or chocolate take it and make these Monster Cookie Skillets!

Or, if you are like me and left with just a giant bag of Snickers πŸ™ go pick up a bag of your favorite peanut butter candy!

What’s the deal with kids not liking Snickers? Serves me right for trying to be cool and let them pick their own candy from the bowl… never again. 

The Sour Patch Kids were the obvious winner this Halloween… Walter thinks it’s because of the bright packaging, but I think it’s just that kids know what they want… sweet sugar rolled in sour sugar. Even the big kids over here love them… we may have stashed away the last 4 bags to save for ourselves πŸ˜‰

Anyways… back to these cookies! There is something about eating a cookie warm out of the oven, loaded with chocolate and peanut butter, topped with ice cream, out of a skillet that makes your heart melt. 

The skillet makes them perfectly gooey on the inside and crunchy on the outside. I recommend these 6.5″ Lodge Cast Iron Skillets for the best results πŸ™‚ 

I used Peanut Butter M&M’s, but any chocolate peanut butter candy will do!

  • 1/2 cup white sugar
  • 2 eggs
  • 1 tsp vanilla
  • 1 1/2 cups flour
  • 1 cup oats
  • 1/2 tsp sea salt
  • 2 tsp baking soda
  • 1 cup chocolate chunks
  • 1 cup Peanut Butter M&Ms (or Resse’s Pieces, Resse’s Peanut Butter Cups, Peanut M&Ms, or all of the above!)


  1. In the bowl of an electric mixer fitted with blade attachment, add butter, peanut butter, brown and white sugar, mix on high for 2 minutes
  2. Add eggs 1 at a time
  3. Mix in vanilla
  4. In a small bowl, whisk together flour, oats, sea salt and baking soda
  5. Slowly add dry mixture to mixing bowl, mix until just fully combined
  6. Fold in chocolate chunks and M&Ms
  7. Chill dough at least 1 hour
  8. Pre-heat oven to 350Β°F
  9. Grease *4 – 6.5 inch skillets
  10. Fill each skillet 3/4 full with cookie dough
  11. Bake for 18-20 minutes
  12. Serve warm and top with ice cream or whipped cream if desired


*I only have 2 skillets so I make them 2 at a time and freeze the rest of the dough. You can also make them as normal cookies instead of skillet cookies, reduce bake time to 10-12 minutes for cookies.
