Monster M&M Cookies

Monster cookies are an amalgam of oats, peanut butter and chocolate chip cookies with an assortment of nuts, candy and raisins thrown into the mix. All the stuff cookie monsters dream of.

I wonder if the cute, fuzzy cookie monster inspired the name or if they were named so because they are a monstrosity in and of themselves?! I like to think it’s a little of both.

I found two types of recipes for monster cookies; flourless and with flour. I made both. The flourless turn out flat and more on the crunchy side. My preference was for the soft, chewy, chunky, floury ones. They are far more fitting and deserving of the monster name.

Use any assortment and combination of candy, nuts or flavored chips: 3 and 1/2 cups worth. With this versatility the possibilities for flavors are endless. These have peanut m&m’s, chocolate chips and caramel pieces. What would go in your monster mix?

 Monster M&M Cookies

Monster cookies are an amalgam of oats, peanut butter and chocolate chip cookies with an assortment of nuts, candy and raisins thrown into the mix.


1 cup peanut butter
1/2 cup butter, softened
1-1/4 cups packed brown sugar
1 cup sugar
1/2 teaspoon salt
3 eggs
2 teaspoons baking soda
1 teaspoon vanilla extract
4 cups quick-cooking oats (not instant)
3 1/2 cups of chocolate chips, candy, nuts, and/or raisins
I used:
1 cup peanut or regular m&m’s
1 + 1/2 cups chocolate chips
1 cup caramel or toffee bits
2 cups all-purpose flour or white whole wheat flour


  1. In a large bowl, combine peanut butter, butter, sugars and salt, beat until light and fluffy. Add eggs, one at a time, beating well after each addition. Beat in baking soda and vanilla. Stir in oats, M&M’s, chocolate chips and caramel. Let stand for 10 minutes. Stir in flour.
  2. Shape scant 1/4 cupfuls into balls. Place on greased baking sheets and gently flatten cookies. Bake at 325° for about 15 minutes or until edges are lightly browned. Cool on wire racks.
