Monster Cookies
Giant chewy peanut butter oatmeal cookies topped with colorful M&M candies.
Ingredients
- 1 cup butter
- 3 cups peanut butter
- 2 cups sugar
- 2 cups brown sugar
- 1/2 tablespoon corn syrup
- 6 eggs
- 4 teaspoons baking soda
- 1 1/2 teaspoons vanilla
- 9 cups oatmeal old-fashioned
- 1 1/2 cups chocolate chips
- 2 lbs. M & M's plain (or candy-coated chocolate pieces)
Instructions
-
Preheat oven to 350 degrees. Spray cookie sheets with nonstick spray or line cookie sheets with nonstick parchment paper or silpat liners. Set aside.
-
In a large mixing bowl blend butter and peanut butter. Add sugar and brown sugar until smooth for 2-3 minutes. Mix in eggs, corn syrup, and vanilla. Stir in baking soda. Add oats and chocolate chips.
-
Using a medium-sized ice cream scoop, drop cookie dough onto an ungreased or parchment-lined cookie sheet. Flatten the dough slightly with your fingertips. Place a handful of M&M's on top of each cookie pressing into the dough.
-
Bake for 10-12 minutes or until barely browned. Let cool on the cookie sheet for 5-6 minutes before transferring it to a cooling rack.
Recipe Notes
NOTES:
- This is a huge recipe and makes 72 large cookies. The recipe can be easily cut in half. For smaller cookies use 2 tablespoons of dough. Form into a ball and place on a prepared cookie sheet.
- For gluten-free cookies be sure to use gluten-free oatmeal.
- I use old-fashioned rolled oats because I love the chewy texture. Quick-cooking oats can be used as well.
- M&M's can be substituted with any candy-coated chocolate pieces or omitted altogether.
- If using a large-size ice cream scoop bake for 14-16 minutes.

My 3yr son and I made these this evening. He loved every little bit that fell over the side of the bowl as I stirred and we shared the first warm cookies right out of the oven. Thank you for posting this recipe.

My husband's grandmother used to make monster cookies. Alas, she is not with us anymore. Cant wait to try them and pay homage to a great lady.

Oh that's sweet. My greatest recipes come from my grandmothers. They are the "tried and true" recipes that work every time. Thanks for sharing that.

Hahaha Thanks Elizabeth. I really appreciate you referring my link. I'm so happy the cookies were a success. They are completely addicting and I started freezing them so I wouldn't eat the entire batch. Then I realized how good they were frozen.

Hi Julie. Cookies are for sharing. Now I would have frozen them and ate them over the next few weeks. You did good! Way to go!

I envision making these with the all-one-color M&M's you can buy now. Then they can really be monster cookies. Red for Elmo, blue for Cookie Monster, green for Oscar?
