1cupM&M’s chocolate candies, plus more for sprinkling on top
Instructions
Preheat oven to 350° F. Line an 9x13 baking pan with parchment paper and set aside.
In a medium bowl, whisk together flour, oats, baking soda and salt. Set aside.
In the bowl of a stand mixer (or using a hand mixer), beat butter, brown sugar and sugar on medium-high speed until light in color, about 3 minutes. Add peanut butter, egg, egg yolk and vanilla. Mix until incorporated. Add flour mixture to wet ingredients and mix just until combined. Stir in chocolate chips and M&M’s by hand.
Transfer dough to prepared baking dish and press down evenly using a spatula or your hands. Add some extra M&M’s on top and press down slightly.
Bake for 25 to 30 minutes or until the edges are set and the center is soft. Allow bars to cool in the pan for 10 minutes before lifting out of the pan and letting them cool completely. Slice and serve.
Notes
Oats: Rolled oats work best for a chewy texture, but quick oats may be used as a substitution.Store bars in an airtight container at room temperature for up to 5 days.Freeze bars in an airtight container or freezer bag for up to 3 months. For best results, wrap bars in plastic wrap.
