Brown butter starts this recipe off, filled with lots of oats, M&M's and chocolate chips they are the perfect cookie. Bite-size these Brown Butter M&M Oat Cookies are dangerous to have around! 

  • Total Time: 32 minutes

Ingredients

Units Scale

  2. Preheat oven to 350F and line baking sheet with a silpat liner, if using.
  3. Whisk the flour, oats, cornstarch, baking powder and salt. Set aside.
  4. In the bowl of an electric mixer cream the butter and sugars for a few minutes. Add in egg, yolk, and vanilla. Mix until fully incorporated. Slowly add in dry ingredients, mixing until no flour streaks remain. Mix in M&M's and chocolate chips.

Notes

I personally brown butter in batches and keep some in fridge but if you can do it this way too.
