Here’s why these flourless cookies will leave you spell bound:

  • SO MUCH PEANUT BUTTER. Almost an entire 16-ounce jar! The peanut butter gives the cookies richness and makes them ridiculously soft without the need for flour or any other added fat, such as butter or oil. (Peanut Butter Protein Cookies are another PB-packed, flourless cookie option.)
  • One Bowl. Low dishwashing commitment for maximum cookie bliss. (Loving the one-bowl situation? Try my One-Bowl Brownies.)
  • No Mixer! A whisk and maybe a rubber spatula are all you need.
  • Minimal Ingredients. This recipe calls for just 7 simple ingredients, most of which you already have in your pantry.

How to Make Flourless Peanut Butter Cookies

Like these Peanut Butter Banana Cookies, this healthy dessert recipe will satisfy even the most intense of cookie cravings.

In fact, these peanut butter cookies taste so decadent and utterly peanut-buttery, I forgot I’d left out the butter until I went back and reviewed the recipe for today’s post.

The Ingredients

  • Peanut Butter. The signature ingredient that gives these ooey gooey cookies their decadent taste and melt-in-your-mouth texture.

Baking with Peanut Butter

  • I recommend classic peanut butter for this recipe and most baking recipes (think Skippy or Jif). Natural style, drippy peanut butters will make the cookies too oily and they will spread too much on the baking pan.
  • You can use creamy or crunchy peanut butter, depending upon your preferences. Creamy is our go-to.
  • Brown Sugar + Granulated Sugar. A mix of the two gives the cookies a caramely flavor and keeps them from spreading out too much.
  • Egg. An essential binder in flourless cookies.
  • Baking Soda. To help the cookies rise.
  • Salt. An essential ingredient to help sweet recipes pop.
  • Chocolate Chips. While these are optional, flourless peanut butter chocolate chip cookies are especially irresistible.

Substitution Tip

You can use up to 1/2 cup of any of your favorite mix-ins. Try peanut butter chips for a double hit of PB or chopped dried cherries or cranberries for a PB&J twist.

  • Pure Vanilla Extract. Can you even bake cookies without it?


Want to trim down the ingredients even more? You can make flourless peanut butter cookies with 3 ingredients!

  • The 3 ingredients you need are peanut butter, eggs, and sugar.
  • Make the flourless peanut butter cookies with brown sugar only (add an additional ¼ cup brown sugar in place of the granulated sugar). Omit the other ingredients.

Heads up: If you use only these 3 ingredients, the cookies won’t have the same depth of flavor or identical texture due to the lack of salt, baking soda, granulated sugar, and vanilla, but they will still be yummy.

The Directions

  1. Stir in the peanut butter, followed by any mix-ins (I do some with chocolate chips and some without). Chill the dough for at least 30 minutes.


Yes, chilling the flourless cookie dough is mandatory or your cookies will spread too much during baking. For a no-chill option, try these Flourless Peanut Butter Oatmeal Bars.

  1. Scoop the cookies into balls, then lightly flatten. Bake flourless peanut butter cookies for 7 to 8 minutes. Let cool a few minutes on the sheet, then ENJOY!

Storage Tips

  • To Store. Store leftover cookies an airtight storage container at room temperature for up to 3 days or in the refrigerator for up to 5 days.
  • To Freeze. Place baked leftover cookies in an airtight freezer-safe storage container in the freezer for up to 3 months. Let thaw over night in the refrigerator.

Meal Prep Tip

Keep prepared cookie dough in your freezer for cookie “emergencies.”

  1. Scoop the dough into balls as directed and arrange them on a parchment-lined baking sheet. Place the baking sheet in the freezer until the cookie dough is hard.
  2. Transfer the cookie dough balls to an airtight freezer-safe storage container or ziptop bag and freeze for up to 3 months.
  3. Bake directly from frozen, adding a few minutes to the baking time. Fresh cookies on demand!
