Instructions

Step 1

In a large bowl, mix the melted and cooled butter, brown sugar, sugar, vanilla, peanut butter, and eggs using a whisk.

Step 2

Mix in the flour, baking soda, baking powder, salt, and oats. Use a rubber spatula to mix until just combined. Add in the mini chocolate chips, M&M's, and mini M&M'S.

Step 3

Preheat the oven to 350°F. Line two cookie sheets with parchment paper. Bake 6 cookies at a time for 12-15 minutes or until the edges are a light golden brown. The middle will still look soft, but will continue to bake from the warmth of the pan after it's out of the oven!

Step 4

Cool the cookies on the baking tray for 10 minutes and then transfer to a cooling rack. Enjoy!
