Sometimes you just need a giant cookie.... one that the is loaded with M&M's, peanut butter, and oats. These flourless cookies are so easy to mix together and bake up a batch! Ours are a little different from other Monster Cookie recipes because we use chunky peanut butter. It adds another crunch texture that really works..... you are going to love these cookies!
Monster Cookies
Makes 4 dozen
1 1/2 cups chunky peanut butter
1/2 cup butter, softened
1 cup sugar
1 cup packed brown sugar
3 eggs
1 1/2 teaspoons vanilla
4 1/2 cups quick oats
2 teaspoons baking soda
2 cups M&M candies
Preheat oven to 350°F. In a large mixing bowl, cream together peanut butter, butter, and sugars. Add eggs and vanilla; beat well. Add oats and baking soda; mix until well combined. With a wooden spoon, carefully stir in M&M candies. Drop by largest cookie scoop (I use my muffin scoop; about 1/3 cup size) onto parchment lined baking sheets. Flatten slightly with the back of a spatula. Bake for 12-14 minutes or until edges start to brown. Remove to cool on wire racks.
Step-by-step tutorial:
Gather your ingredients. You will need butter, crunchy peanut butter (creamy works great too), brown sugar, sugar, eggs, vanilla, quick oats, baking soda, and M&M's.

In a large mixing bowl, cream together the stick of butter, 1 1/2 cups peanut butter, 1 cup sugar, and 1 cup packed brown sugar. Add 3 eggs and 1 1/2 teaspoons vanilla and beat until creamed.
Add 4 1/2 cups quick oats and 2 teaspoons baking soda. Mix until well combined. Remove from mixer and stir in 2 cups M&M's carefully with a wooden spoon.
Now try your best not to eat all the cookie dough before baking!

Place large balls on baking sheet. I use my largest cookie scoop which is also the one I use for muffins. I like to take a spatula and flatten the cookie dough balls slightly before baking.

Bake at 350°F for 12-14 minutes, or until the edges start to brown. Allow to cool a few minutes on the baking sheet.

Transfer to a wire rack to cool completely.

These cookies are AMAZING warm with a tall glass of milk!
