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
  1. Mix all ingredients together in a medium mixing bowl.

  2. Divide the resulting dough into 12 equal portions (a little larger than a walnut) and place on a baking sheet.

  3. Using a fork, press the cookie to about 1/3 inch thickness.

  4. Bake at 350 for 18-20 minutes.

  5. Cool completely before serving as they fall apart when still warm.

  6. 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.

  7. 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.
