M&M Cowboy Cookies

  • Total Time: 15 minutes
  • Yield: 0 about 2 1/2 dozen 1x


  • 1 cup butter, softened
  • 1 cup light brown sugar
  • 1/2 cup granulated sugar
  • 1 large egg
  • 1 large egg yolk
  • 1 tablespoon vanilla extract
  • 1 3/4 cups All-Purpose Flour
  • 1 cup quick-cooking or old-fashioned oats
  • 1 teaspoon baking powder
  • 1 teaspoon baking soda
  • 1 teaspoon salt
  • 1 cup Rice Krispies (or Cornflakes will work too)
  • 3/4 cup shredded sweetened coconut
  • 1 1/4 cups chocolate chips (I use half milk & half semi-sweet)
  • 1 1/4 cups miniature M&Ms


  1. Preheat oven to 325ºF.
  2. Beat together the butter and sugar until smooth and creamy.
  3. Add the egg and the egg yolk and mix well. Add the vanilla and mix well.
  4. Add the flour, oats, baking powder, baking soda, and salt, mix until just combined. Add the Rice Krispies, coconut, and chocolate chips and mix well. Finally, add the mini M&M’s and stir in gently by hand (the M&M’s are so tiny and fragile, they break too easily if you mix them in with your mixer) .
  5. Scoop the dough onto lined baking sheets, about 2 inches apart.
  6. Bake for 12-15 minutes until edges are lightly golden. Let cool on the baking sheet before transferring to a wire rack.
