Ingredients

For the Cookies:
  • ½ cup butter softened
  • ½ cup peanut butter
  • ½ cup white sugar
  • ½ cup light brown sugar packed
  • 1 teaspoon vanilla extract pure
  • 1 egg
  • ¾ cup all-purpose flour
  • ½ teaspoon baking soda
  • ¼ teaspoon baking powder

  • 1 cup oats quick cooking
For the Filling:
  • 3 tablespoons butter softened
  • 1 cup confectioners' sugar
  • ½ cup peanut butter smooth
  • 2 ½ tablespoons heavy whipping cream

Instructions

For the Cookies
    Cup of Yum
  1. Preheat oven to 350F.
  2. In the bowl of a stand mixer, cream together the butter, peanut butter, white sugar, brown sugar, and vanilla until light and fluffy. Beat egg separately by hand, then add to the mix and beat again.
  3. In another bowl, combine the flour, baking soda, baking powder, salt, and oatmeal. Whisk them to combine equally. Add these dry ingredients to the creamed mixture and mix on low until evenly combined.
  4. Pull by teaspoons and form into round balls with your hands. Drop onto a greased baking sheet, and press each mound down with a fork to form 1/4 inch thick cookies. Bake for 7 minutes, or until light brown.
For the Filling
  1. In a stand mixer or with a hand mixer, cream together the butter and peanut butter.
  2. Add confectioner's sugar a little at a time until fully incorporated, then add the cream a little at a time until you reach the desired consistency. You may not use all the cream.
  3. Spread the filling onto cooled cookies, then combine with a second cookie to form sandwiches.

Notes

  • Store the peanut butter sandwich cookies in an airtight container for up to three days to keep them fresh and soft.
