Flourless Peanut Butter Cookies Recipe

Our gluten-free peanut butter cookies are one of my favorite dessert options. But, because they contain gluten-free flour, they’re not suitable for those with sensitivities or allergies to flour-based products. So when that sweet tooth kicks in, these flourless peanut butter cookies are the perfect solution.

You can use crunchy or smooth natural peanut butter for this recipe, or make a batch of both and see what texture you prefer. I don’t add any butter either, so these cookies are not only gluten-free but also dairy-free. Instead, the egg, sugars, and peanut butter bind everything together to create these deliciously soft and chewy cookies!

Ingredients

  • Unsalted Natural Peanut Butter: Be sure to use unsalted. If, for some reason, there is salt in it, just omit adding extra salt.
  • Brown sugar: Used to sweeten the cookies and add to the golden brown coloring.
  • White sugar: Another simple sweetener.
  • Egg: Helps to bind together the dry ingredients to form the cookie dough.
  • Vanilla extract: Pure vanilla extract has a great flavor.
  • Baking soda: This helps to give the cookies their texture and chewiness.
  • Salt: Add only if you use unsalted peanut butter.

Tips and Suggestions

  • Don’t try to move the cookies right when you take them out of the oven. They need to cool before moving, or they’ll break apart. As they cool, they’ll firm up.
  • Even though you might be tempted to add more peanut butter, pay close attention to what the recipe calls for. Adding too much peanut butter can cause issues with the texture of the cookies, making them crumbly.
  • You can use almond butter or other nut butters for this recipe, too.

Why Are My Cookies Still Soft?

If your flourless peanut butter cookies aren’t hardened after cooling, place them in the fridge for a short amount of time. This will help them firm up so they won’t fall apart.

What Else Can I Add?

There’s always room for more ingredients in these cookies! Adding mini chocolate chips, crushed walnuts, shredded coconut, or even some mini marshmallows would be fun additions.

Can I Freeze Them?

You can! Once they’ve cooled down to room temperature, wrap the cookies in plastic wrap or aluminum foil, then store them in a freezer-safe bag. They’ll be good for up to 2-3 months. Let them thaw at room temperature, and enjoy!

Storage Instructions

Once your homemade flourless peanut butter cookies have cooled down completely, place them in an airtight container or in a ziplock bag. They’ll stay fresh for 4-5 days at room temperature.

  1. I’ve made this recipe twice now and intend to continue with it in the future. It’s flavorful and delightful. I sprinkled the tops with a pinch of salt to cut some of the sugar, and that worked quite well both times. Thanks for this tasty recipe!

  2. Thank you very much. I can now have something to munch when i feel like a cookie. I have IBS so I find it difficult to take anything with flour. 🙏🏿
