With just 3 ingredients, these easy gluten free peanut butter cookies without flour will become your favorite quick and simple sweet snack.

Why you'll love these 3 ingredient cookies!
As someone who doesn't eat gluten or dairy, these 3 ingredient peanut butter cookies are my go to when I'm craving something sweet that's super easy to make. We've been making these for years!
You can make the cookies by using crunchy or creamy peanut butter (we show both in the photos), you can sprinkle extra sweetener on top after baking, or add a Hershey's kiss on top as a fun holiday variation. Make them sugar free by using a sweetener like monkfruit.
Main ingredients
- peanut butter - creamy or crunchy; other types of nut butter can be used too
- granulated sugar - brown sugar will also work and will give the cookies a stronger molasses flavor. You can use monk fruit as a 1:1 substitute for a low carb sugar-free version.
- large egg - or a vegan substitute like chia eggs
- optional - vanilla extra add's a nice punch of flavor!
Variations
During the holiday we use the gluten-free peanut butter cookies as a base and add a Hershey's kiss on top. To make this version, just shape the dough into small balls, and to the baking pan without making the criss cross pattern, and press the Hershey's kiss down into the ball. Bake as the recipe states below.
How to make 3 ingredient peanut butter cookies
To start, preheat your oven to 350F degrees and make sure your rack is in the center of your oven. Grab your favorite cookie sheet and line it with some parchment paper for easy clean up (optional).
In a medium-sized mixing bowl combine your peanut butter, sugar, and egg and stir until just combined.
Roll the batter into balls about 1-inch in diameter. You should be able to make about 16 cookies.
Using a fork, gently smoosh the balls to create that classic criss-cross peanut butter cookie pattern.
Bake in a preheated oven for 8-9 minutes. Allow the cookies to cool for a few minutes before digging in! As an optional idea, you can sprinkle on a little sweetener like we did in some of the photos.
Jenni's tips
- Use natural peanut butter instead of regular peanut butter to make these cookies even healthier than they already are.
- Mix things up by using other nut butters including sun butter and almond butter.
- Add some mini-chocolate chips or dip half of the cookie in melted chocolate for an extra-special cookie.
- Instead of using a fork for the criss-cross pattern, consider adding a Hershey's kiss to the top of your cookies. Bake as usual.
- These freeze well for later!
