Monster Cookies
Meet the vintage kitchen-sink cookie packed with chewy oats, rich peanut butter, and melty chocolate under a confetti of mini M&Ms. They bake up bakery-big with crisp edges and soft centers that vanish the second they’re cool enough to grab. I press a few extra candies on top before baking for extra color.

Ingredients
Instructions
- Step 1
Preheat oven to 350℉. Line cookie sheets with parchment paper and set aside.
- Step 2
Cream the butter, brown sugar, and white sugar in a large mixing bowl with an electric mixer until light and fluffy.
- Step 3
Add the eggs one at a time and beat until incorporated.
- Step 4
Use a mixer to beat in the peanut butter, corn syrup, and vanilla and mix well.
- Step 5
Stir in the flour, baking soda, and oats.
- Step 6
Fold in the mini M&Ms and mini chocolate chips just until combined.
- Step 7
Each cookie is 3 tablespoons in size. Drop 3 tablespoons of dough right next to each other and squish them together to form one cookie. I flattened mine for a larger, flatter cookie. You can keep them mounded for a softer cookie.
- Step 8
Space cookies 2 inches apart.
- Step 9
Bake at 350℉ for 9-12 minutes.
- Step 10
Press a few M&Ms into the top of each cookie right away, if desired.
- Step 11
Let the cookies cool on the cookie sheet for 5-10 minutes before moving to a cooling rack.
