  • 1 cup packed brown sugar
  • 1 cup granulated sugar
  • 1/2 cup salted butter, softened (1 stick)
  • 1 1/2 cups creamy peanut butter
  • 3 large eggs
  • 1 tablespoon vanilla extract
  • 1 1/2 cups quick oats
  • 3 cups old-fashioned oats
  • 1 teaspoon baking soda
  • 1 1/2 cups mini m&m's
  • 1 cup mini chocolate chips


  1. Heat oven to 350 degrees. Prepare a jelly roll pan or large cookie sheet by lining it with parchment paper or baking mat. (A baking mat works the best when spreading out dough. See the link in the blog post for the baking mats I use.)

  2. In large bowl add the brown sugar, granulated sugar, peanut butter, and butter. Then beat until pale in color and fluffy.

  3. Add the eggs and vanilla extract and continue to mix.

  4. Add in the oats and baking soda. If using a stand mixer use the paddle attachment. Otherwise you may want to mix by hand or wooden spoon.  The mix will be very thick.

  5. Set aside about 1/4 cup of M&Ms for the top. Add in the rest of the M&Ms and chocolate chips. Mix together until well blended.

  6. Dump onto your baking mat lined cookie sheet and spread out. Sprinkle the reserved M&M's on top. Press down into dough.

  7. Bake for 17-19 minutes. Let cool for 30 to 45 mins before slicing.  Do not overcook.  It should brown slightly around edges.
