The Simplest Ingredients

Sugar, peanut butter, egg, and vanilla extract that’s all that is needed for a quick dessert. Do use the best quality of each for amazing flavor.

Becuase there is so very much sugar in the recipe as written, use an unsweetened peanut butter here.

If use you an unsalted peanut butter, you may want to add 1/4 teaspoon salt to flavor the cookies just slightly.

Subsitute most any nut or seed butter to make the cookies suitable for food allergies.

Gluten-Free Without Trying

As there is no flour at all in these cookies, they are perfect to give to gluten-free friends and family. While also skipping gluten-free flours or baking needs.

They also make great treats for potlucks where food senstivities might be an issue (substitute almond butter or sunflower seed butter to avoid peanuts, too).

Optional Additions

These flourless peanut butter cookies are quite amazing just as written. However a person could do a few things to customize and make them even more decadant:

  • Drizzle the tops of the cooled cookies with melted chocolate.
  • After pressing the raw dough with the fork, top each cookie with a few chocolate chips before baking.
  • Sprinkle the tops of the raw dough with finely chopped nuts before baking.
  • Make small cookies and sandwich some chocolate frosting or melted chocolate between two cookies.

Great Keepers

These cookies will stay fresh and tasty for about 5 days at room temperature. For longer storage, put them in bags or other airtight containers and freeze for up to 6 months.
