Equipment

Ingredients

  • 1 egg
  • 1 cup Splenda or your favorite sugar substitute
  • 1 teaspoon baking powder
  • ½ teaspoon vanilla
  • 1 cup creamy peanut butter
  • 1 teaspoon water

Instructions

  • Preheat the oven to 350 degrees.
  • In a mixing bowl, beat together the egg, sugar substitute, baking powder and vanilla for about a minute.
  • Add the peanut butter and water and beat together.
  • The mixture will be pretty dry; just make sure the peanut butter is blended in with the other ingredients.
  • Measure out a heaping teaspoon of batter for each cookie and place on a baking tray that has been sprayed with non-stick cooking spray or lined with parchment paper.
  • Then using a fork, make indentations into each cookie. Spray the fork with cooking spray so it doesn't stick to the cookie.
  • Bake 8-10 minutes until cookies feel firm and are slightly browned.
  • Transfer the cookies to a baking rack and cool.

Notes

Tips
  • The mixture comes together quickly and may look a little dry; just be sure the peanut butter is fully blended in with the other ingredients.
  • Use a fork to make the classic criss-cross pattern on top of each cookie.
  • Since these cookies are flourless, lightly spray the fork with non-stick cooking spray to prevent sticking instead of dipping it in flour like traditional peanut butter cookies.
Storage & Make Ahead
  • Store cookies in an airtight container at room temperature for up to 3 days.
  • For longer storage, refrigerate for up to 1 week.
  • The dough can be made ahead and chilled for up to 24 hours before baking.
