Peanut Butter Cookies

  • 1 cup creamy peanut butter
  • 1/2 cup erythritol
  • 1 teaspoon pure vanilla extract
  • 1 large whole egg
  • 1/4 teaspoon salt

Cream Cheese Frosting


  • Mix all ingredients together in a medium mixing bowl.
  • Divide the resulting dough into 12 equal portions (a little larger than a walnut) and place on a baking sheet.
  • Using a fork, press the cookie to about 1/3 inch thickness.
  • Bake at 350 for 18-20 minutes.
  • Cool completely before serving as they fall apart when still warm.
  • Meanwhile cookies are cooling, prepare frosting. Take a medium mixing bowl and using a hand mixer beat together cream cheese and butter. Slowly add powdered sweetener in until creamy.
  • Pipe frosting onto bottom of one peanut butter cookie and top with another peanut butter cookie. Continue until all whoopie pies are made. Makes 6 whoopie pies.
