  • 1 cup all-purpose flour (130 grams)
  • cup old-fashioned rolled oats
  • 1 ½ teaspoons baking powder
  • ½ teaspoon salt use ¼ if using salted butter or spread
  • 1 cup crunchy peanut butter
  • 1 stick unsalted butter, room temperature (114 grams)
  • 1 cup firmly packed light brown sugar (200 grams)
  • cup granulated sugar (65 grams)
  • 1 large egg
  • 1 -¼ teaspoons vanilla extract
  • 1 cup milk chocolate chips plus another cup of Reese's chips -- optional
  • cup M&Ms, in holiday colors or peanut butter chips


  • Preheat oven to 350°F.
  • Combine flour, oats, baking powder and salt in a bowl and set aside.
  • Cream the peanut butter, butter, and both sugars in large mixing bowl with electric mixer on medium-high speed until fluffy. Beat in egg and vanilla. Using lowest speed of mixer or by hand, stir in the flour mixture.
  • Stir in chocolate chips and peanut butter chips (if using). Form mixture into 1-inch balls. Place 3 inches apart on nonstick baking sheets and flatten with tines of fork in criss-cross pattern. Bake 10 to 12 minutes or until edges are lightly browned and centers are still soft.
  • As soon as you pull the cookies from the oven, scatter holiday M&Ms on top. Cool 1 minute on baking sheet; transfer to wire racks. Cool completely. Makes about 36 cookies depending on what your idea of a 1 inch ball is.
