A classic turned gluten-free! These Gluten-Free Peanut Butter Cookies are soft, chewy and delicious!

I realized I have a lot of peanut butter recipes, but I don’t have one for just a classic, good ol’ peanut butter cookie. I made these gluten-free but you can just sub regular flour if you like. These cookies are soft and easy to make, plus you just need one bowl and a spoon to mix everything up. Let’s make them!

Gluten-free Peanut Butter Cookies

These are the simple, pantry staples you’ll need to make these gluten-free peanut butter cookies:

  • Peanut butter: I use the more processed type of peanut butter for baking, save the natural stuff for toast, sandwiches and smoothies.
  • Sugar: this recipe calls for regular granulated sugar as well as brown sugar. Either dark brown sugar or light brown sugar are fine.
  • Eggs: Use room temperature eggs for best results in baked goods.
  • Dry ingredients: salt, baking soda and oat flour.

What kind of peanut butter is best for peanut butter cookies?

For most any baking, I use JIF natural. Now I know I just said above not to use the natural kind but the JIF natural is not really natural. It’s still processed, there’s oils and sugar added and it doesn’t separate. I might deviate from this rule for no-bake goods, but any time a baking recipe calls for peanut butter, it’s best to go with the more processed types unless another type is mentioned.

Is peanut butter gluten-free?

Generally, yes. Peanuts and the usual additional peanut butter ingredients are naturally gluten-free foods. If you are concerned, just make sure to check labels as I suppose it’s always possible for a brand to add some sort of sneaky ingredient that contains gluten, but the majority of peanut butters you’ll see on grocery store shelves are certified gluten-free.

How to make

To make these cookies, start by measuring peanut butter and adding it to a large mixing bowl. Add both sugars, oat flour, baking soda and salt and stir until fully combined. Then add the eggs and stir again.

Use a cookie scoop (affiliate link) to place dough by the 1.5 tbsp onto a parchment-lined baking sheet.

Dip a fork in oat flour to get that classic cross-hatched pattern on your peanut butter cookies.

Bake cookies at 350F for 9-10 minutes and allow to cool on the baking sheet for about 5 minutes before transferring to a wire rack to cool.

How to make oat flour

This recipe calls for oat flour, but the good news is you don’t necessarily need to go out and buy store-bought.

If you have plain oats in the pantry (quick-cooking or regular are fine), just place them in a blender or food processor and blend until ground to a powder consistency. Voila!

    Question: Do I grind enough oats to make 1/4 C, or do I measure it out and then grind it?
