1 jar: Makes 12 monster cookies or 36 regular cookies


  • 1 ¼ cup rolled oats

  • ¾ cup all-purpose flour

  • ½ cup packed brown sugar

  • ¼ cup granulated sugar

  • ½ teaspoon baking powder

  • teaspoon baking soda

  • ½ cup coarsely chopped dry roasted peanuts

  • 1 cup miniature chocolate-covered peanut butter cups, halved


  1. In a 1-quart jar layer oats, flour, brown sugar, granulated sugar, baking powder, baking soda, and peanuts. Place peanut butter cups in a plastic bag. Set on top of peanuts in jar. Seal jar; include directions for making cookies.


Preheat oven to 350°F. Line a cookie sheet with parchment paper or foil. Remove peanut butter cups from jar; set aside. Empty the remaining contents of the jar into a large bowl. In another bowl, whisk together 1/2 cup creamy peanut butter, 1/4 cup softened butter, 2 eggs, and 1/2 teaspoon vanilla. Add to flour mixture; stir until combined. Gently stir in peanut butter cups. Use a 1/4-cup measure or scoop to drop mounds of dough about 4 inches apart onto prepared cookie sheet. Flatten dough mounds to about 3/4 inch thick. Bake for 12 to 14 minutes or until edges are brown. Cool on cookie sheet for 1 minute. Transfer to a wire rack and let cool. (For regular-size cookies, drop dough by rounded teaspoons 2 inches apart on cookie sheet. Bake for 9 to 11 minutes.)


Store jar of mix in a cool, dry place for up to 1 month.
