Peanut Butter Sandwich Cookie Filling
Peanut butter filling for sandwich cookies.
  • ½ cup creamy peanut butter
  • 3 cups confectioners' sugar
  • 1 teaspoon vanilla extract
  • 5 -6 tablespoons milk
  1. In a large mixing bowl, beat the peanut butter, confectioners' sugar, vanilla extract and enough milk to achieve spreading consistency. Spread filling on half of the cookies and top with another cookie.
I’m keeping my sandwich cookies refrigerated because of the milk in the filling.
