I’m always looking for ways to cure my sweet tooth, without tipping the scale. These flourless peanut Butter cookies are naturally low calorie – about half of a traditional peanut butter cookie.

That means they make an incredible snack without all the guilt.

I’ve been creating “skinny” versions of my favorite dessert recipes for years, with great success! These cookies are no exception.

Healthy Flourless Peanut Butter Cookies

They’re such a great fix for a last minute craving or sweet tooth. They are perfectly tender with a little chew.

Why You’ll Love It

  • Lower Calorie – These cookies are just 80 calories each! However, this recipe is so incredible, you may have a difficult time stopping at just one.
  • Gluten Free – They’re naturally gluten free, but you’ll never miss the flour. They stack up to traditional peanut butter cookies without all the calories.
  • Irresistible – Maybe you have more willpower than I do? You should probably make them and find out!

Ingredients and Substitutions

  • Peanut Butter – Creamy or crunchy, your choice. For best results, don’t use natural peanut butter.
  • White Granulated Sugar – If you really want to reduce the calories, you can even use a little less than indicated in the recipe card.
  • Egg – the glue that holds it all together. 
  • Salt – salt brings out the flavors of all the ingredients in these cookies, making them the ultimate sweet and salty treat!
  • Vanilla – I like to use homemade vanilla, but any will do!
  • Baking Soda – the leavening agent that makes them rise.

Variations

  • Add chocolate chips
  • Add nuts

  1. Prep – Heat oven and prep cookie sheets with parchment or silpat.
  2. Make Cookie Dough – Combine sugar, peanut butter, salt, baking soda and vanilla until smooth. Add egg until just combined.
  3. Roll into Balls – Use a dough scoop or roll into balls and bake as directed.

Tips

  • I use a cookie scoop to achieve a perfect portion.
  • Always bake cookies in a pre-heated oven.
  • Bake the cookies on a parchment lined baking sheet. They will stick if you bake them directly on the sheet and it also makes clean up a breeze.

Frequently Asked Questions

What does baking soda do for flourless cookies?

Baking soda helps keep them soft and chewy without adding flour. It gives them just enough rise that they still have that perfect chewy texture you crave!

Is peanut butter gluten free?

Most brands of peanut butter are gluten free! With that said, it’s so important to check the label on any peanut butter you pick up, especially if you’re living with a gluten sensitivity or allergy.
Some brands are also processed in facilities that process wheat, so there could always be risk of contamination. Carefully choose your peanut butter brand if this is an issue for you!

  • Freeze – They will freeze well for up to three months. Simply thaw them out before serving.
