Monster Cookies

Total Time

Prep: 15 min. + standing Bake: 15 min./batch


about 2-1/2 dozen

This recipe combines several favorite flavors—peanut butter, butterscotch and chocolate—in one big cookie. Before baking, I like to press a few extra M&M's on top for added color. —Patricia Schroedl, Jefferson, Wisconsin

  • 1 cup peanut butter
  • 1/2 cup butter, softened
  • 1-1/4 cups packed brown sugar
  • 1 cup sugar
  • 3 large eggs, room temperature

  • 1 teaspoon vanilla extract
  • 4 cups quick-cooking oats
  • 1 cup M&M's
  • 1 cup butterscotch chips

  1. In a large bowl, cream peanut butter, butter and sugars. Add eggs, 1 at a time, beating well after each addition. Add baking soda and vanilla. Add oats, M&M's, butterscotch chips and peanuts; let stand for 10 minutes. Stir in flour (the dough will be crumbly).
