Monster Cookies

Preheat oven to 350°F. Line a baking sheet with parchment paper or a silicone mat.

In a bowl, whisk flour, baking soda, cornstarch, baking powder, and salt. Set aside.

In a large bowl, cream butter, sugar, and both kinds of peanut butter until light and fluffy. Mix in egg and vanilla. Scrape down the sides if needed.

On slow speed on a hand mixer or stand mixer, add flour mixture to wet ingredients. Stir in oats, chocolate chips, and M&Ms.

Measure out the dough into 2-inch balls and place on a baking sheet. Add more M&Ms to the top of each cookie.

Bake for 11–13 minutes or until edges start turning golden brown. Allow to cool for 10 minutes before moving to a cooling rack. Grab a glass of milk and enjoy!
