Monster Mash Cookies

Who else is pumped for Halloween? I know this year is going to look different, but I still can’t help but be excited – Halloween is one of my favorite days. I’m planning lots of fun eats and crafts at home. We’ve got our costumes and we’re ready!

I have a lot of cookies on this blog, but Monster cookies are one of my favorites – and when you add candy eyeballs, they become deliciously perfect for Halloween.

Ingredients

  • 1/2 cup unsalted butter, at room temperature
  • 3/4 cup packed brown sugar
  • 1/4 cup granulated sugar
  • 1/2 cup creamy peanut butter
  • 1 large egg, at room temperature
  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 1/4 cups old-fashioned oats
  • 1/3 cup peanut butter chips
  • 1/3 cup semi-sweet chocolate chips
  • 1/3 cup mini M&Ms + additional for topping
  • Candy eyeballs, optional

Monster cookies are what I call clean-out-the pantry cookies. Whatever chips, nuts, and candy I have to use up are what get dumped in!

Directions

  • Preheat the oven to 350 degrees. Line a baking sheet with baking parchment.
  • Using a mixer, cream together the butter and sugars until thoroughly combined. Beat in the peanut butter, egg, and vanilla.
  • In a separate bowl, whisk together the flour, baking soda, and salt. Add to the wet ingredients and beat until thoroughly combined, scraping down the sides as needed.
  • Beat in the oats.
  • Fold in the peanut butter chips, chocolate chips, and mini M&Ms.
  • Roll into 1-inch balls and place 3 inches apart on the baking sheet. Push several candy eyeballs into each cookie, and some additional mini M&Ms.
  • Bake for 10-11 minutes. Let cool on the baking sheet for 5 minutes before transferring to a wire wrack to cool completely.

If you want cookies that look smooth and round, roll the dough into balls. If you want a more lumpy, abstract look, drop the dough by tablespoons full onto the prepared cookie sheet.

More Treats for Halloween

Halloween is one of my favorite holidays so I love cooking up fun treats for it! Shrunken Head Punch and Halloween Caramel Corn or Halloween Muddy Buddies are my go-tos for crowd snacks.

For special Halloween desserts, we love Candy Corn Ice Cream and Candy Corn Chocolate Chip Cookies – combining them into ice cream sandwich is absolutely perfect!
