Monster Cookies

Updated: Mar 11

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! They make the perfect after school snack with a glass of milk. You are going to love these cookies!


Monster Cookies

Makes 4 dozen

1 1/2 cups creamy 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, creamy peanut butter (crunchy 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!
