HEALTHY PEANUT BUTTER COOKIES
There’s nothing more classic than freshly baked homemade peanut butter cookies. They were always a favorite when I was growing up and I couldn’t wait to make a flourless version ever since going grain free due to my autoimmune condition.
We’ve had so much remaking some classic desserts like Peanut Butter Chocolate Bars, Chocolate Chip Cookies and Brownies.
INGREDIENTS TO MAKE 3 INGREDIENT PEANUT BUTTER COOKIES:
It honestly doesn’t get more easier than 3 ingredient peanut butter cookies. Like I said, you probably already have all of these simple ingredients in your kitchen and if not, you can simply use what you have instead.
- peanut butter (use smooth or crunchy)
- granulated or golden monk fruit sweetener (or use your favorite low carb sweetener such as SWERVE, erythritol etc)
- egg
OPTIONAL BUT HIGHLY RECOMMENDED TO HELP BRING OUT THE FLAVOR:
- vanilla
- pinch of sea salt
HOW TO MAKE FLOURLESS PEANUT BUTTER COOKIES:
PREHEAT THE OVEN AND PREP THE BAKING SHEET: You’re going to start off by preheating the oven to 350 degrees F. Line a baking sheet with parchment paper or a silicone mat.
MAKE THE BATTER: In a large bowl, beat together the peanut butter and monk fruit sweetener until smooth. Add the egg and mix until well combined. At this point, you can also add vanilla, cinnamon, or a pinch of salt to bump up the flavor.
ROLL INTO BALLS: Scoop out tablespoon-sized dough balls. Roll into an extra bowl of granulated monk fruit sweetener, if desired, to coat the outside of the dough ball.
Place dough balls on prepared baking sheet at least 2 inches apart, and then use a fork to flatten and form a criss-cross pattern.
BAKE: Bake in preheated oven for 9 to 14 minutes, until the cookies are just slightly browned on the bottom. Be careful not to over-bake. Allow to cool on the baking sheet for 3 minutes, then transfer to a wire rack to cool completely.
WHAT OTHER MIX-INS CAN I USE TO MAKE GLUTEN FREE PEANUT BUTTER COOKIES?
If you’re not opposed to tossing in more add-ins to your gluten free peanut butter cookies, some delicious options include:
- chocolate chips
- chopped nuts
- shredded coconut
ARE FLOURLESS PEANUT BUTTER COOKIES PALEO?
These soft peanut butter cookies are naturally gluten free but if you want a paleo friendly nut butter cookie, you can switch out the peanut butter with almond butter, cashew butter or pecan butter instead.
For a nut free version, use sunflower seed butter, tahini or pumpkin seed butter.
WHAT OTHER SWEETENERS CAN I USE IN GLUTEN FREE PEANUT BUTTER COOKIES?
Monk fruit sweetener is my preferred sweetener I use in my low carb desserts. I find it mimics the taste of regular sugar the most without any aftertaste or cooling effect like I get with other sugar free sweeteners.
If you don’t have monk fruit sweetener, feel free to use erythritol or SWERVE if those are your preferred sugar free sweeteners. You may have to adjust the amount according to your taste.

Yes, absolutely! I always make a double batch of grain free cookies since they are perfect for making ahead and they’re freezer friendly!
HOW TO FREEZE GLUTEN FREE PEANUT BUTTER COOKIES?
To freeze your sugar free peanut butter cookies, simply place the entire baking sheet of baked cookies in the freezer for 30 minutes. After 30 minutes, transfer the cookies to a resealable bag or an airtight container and store it in the freezer for up to 3 months.
