These Sugar-Free Peanut Butter Cookies are so simple and tasty! With only four ingredients, they’re low-carb, gluten-free, and dairy-free, too!

I love baking cookies. There are so many cookie recipes on FFF, simply because there can never be too many!
That’s why today is the perfect day to bring you a new, easy, delicious, and sugar-free peanut butter cookie recipe! These cookies are incredibly easy to make, protein-packed, and HEALTHY for you and your crew.
They are also naturally gluten-free and dairy-free, with no flour in the recipe at all! These cookies are certainly a WIN all around and are the perfect high-protein treat any time of day.

Are sugar-free peanut butter cookies Healthy?
Not only are these cookies free of all gluten, sugar, and dairy, they’re also keto-friendly. When on the keto diet, it’s important to keep your intake of carbohydrates to the lowest amount possible to bring your body into a state of ketosis, where it’s burning fat instead of glucose (the main form of sugar found in carbohydrates) for energy.
Plus, these cookies use peanut butter as the main ingredient, which is packed full of protein, healthy fats, fiber, and vitamin E. Just make sure to buy a high-quality peanut butter with no added sugars, oils, or hydrogenated fats.
If you’re worried about the sweetener in this recipe, you can reduce the amount you add, or omit it entirely. Peanut butters have a natural sweetness to them, so these cookies will taste just fine without it!
Which Sweetener is the best for these Cookies?
For these sugar-free cookies, I used Truvia sweetener. I attempted to make a batch using baking Stevia, but they turned out horrible so I do not recommend it! You should be able to use any other granulated sweetener replacement, such as Swerve, but you may want to cut back on the sweetener as Swerve can be very sweet. Just bake a trial half-batch and see how they taste, then adjust the sweetener amount accordingly.

How to make ahead and store
These cookies last well when stored in the refrigerator or freezer. If you plan to store them in the refrigerator, I recommend placing them in an airtight container and storing them for up to a week. If you want to freeze them, go for it! Simply place the cookies on a baking tray and freeze them until solid. Then store them in an airtight container or freezer-safe bag labeled with the date you made them for up to 3 months. To thaw, leave them in the refrigerator overnight and gently warm them through in an oven the next day.

Serving Suggestions
If your diet allows for sugar, there’s nothing better on a hot day than some Frozen Yogurt or this Chocolate and Pomegranate Ice Cream with some peanut butter cookies. In the colder months, swap the ice cream for a mug of Vegan Hot Chocolate and you have a warming, filling treat!

Ingredients
- 1 cup peanut butter
- 3/4 cup granulated Truvia
- 1/2 teaspoon salt
- 1 egg
Instructions
- Preheat your oven to 350°F and line a cookie sheet with parchment paper.

- In a large bowl, beat together the peanut butter, Truvia, and salt with an electric hand mixer.

- Add in the egg and beat until the mixture thickens up and forms a dough. It's okay if it seems a little wet!

- Use a tablespoon measure to portion out a heaping tablespoon of dough per cookie, and place each one an inch apart on the parchment paper. Use a fork to press out the dough to about 1/3 inch thick, and make a cross-hatch pattern on the surface.

- Bake in the oven until set, about 16 to 18 minutes. They will feel soft at first, but will firm up as they cool.

- Let cookies cool on the pan completely for crunchier cookies or for about 10 minutes for softer cookies, and then transfer them to a cooling rack to cool completely.
