Kitchen Tools You’ll Need

How to Make 3 Ingredient Sugar Free Peanut Butter Cookies
Step 1. Preheat your oven to 350 degrees Fahrenheit and get your cookie sheet ready by greasing it or lining it with parchment paper to prevent the cookies from sticking. Prepping your baking surface is essential for an effortless release once they’re done baking.
Step 2. In a large mixing bowl, cream together the peanut butter and sugar alternative. Mix until the mixture is light and fluffy. This is an important step that helps incorporate air into the batter, which contributes to the finished cookie’s texture.
Step 3. Add in the egg and mix until everything is well combined. The egg acts as a binder, holding the ingredients together and giving the cookies structure. You’ll know you’re done when the mixture is smooth and uniform in appearance.
Step 4. Using a cookie scoop, portion out the dough and roll it into balls. Place them on the prepared baking sheet, spacing them about two inches apart. This distance is key to allow for some spreading as they bake, resulting in nicely shaped cookies.
Step 5. Gently press down on each dough ball to flatten them to half their thickness. This not only shapes the cookies but allows them to bake more evenly.
Step 6. Take a fork and create a crisscross pattern on top of each cookie by pressing down gently. This step adds a rustic look and further flattens the cookies, which helps them bake properly.
Step 7. Bake the cookies for 7 to 10 minutes, monitoring closely until the edges are golden brown. The centers may still look slightly soft, which is perfectly fine, as they will firm up as they cool.
Step 8. Once baked, let the cookies sit on the cookie sheet for a few moments before transferring them to a cooling rack. This resting period helps them set up, making it easier to move them without breaking.

Serving Suggestions
These peanut butter cookies are perfect for various occasions. Enjoy them with your morning coffee for a quick breakfast treat or pack them in lunch boxes for a sweet afternoon snack. They also make great additions to family meals or gatherings. Leftovers can be stored and enjoyed over the following days—if they last that long!
Pro Tips for Best Results
- Make sure to thoroughly cream the peanut butter and sugar alternative together to achieve a light texture.
- Keep an eye on the cookies as they bake—ovens can vary, and slight differences in time can change the final product.
- Allow the cookies to cool completely to enhance their flavor and texture.
- Store cookies in an airtight container to maintain their freshness.
Common Mistakes to Avoid
- Not measuring ingredients accurately. Using a heaping cup of peanut butter or sugar alternative can make cookies too dense. Always level off your measuring cups for the most accurate results.
- Skipping the cooling time. Moving cookies too soon to a cooling rack may lead to them breaking apart. Let them sit briefly on the baking sheet to firm up before transferring.
- Overbaking the cookies. If you leave them in the oven too long, they can become dry and hard. Look for golden brown edges and remove them at that point.
- Not spacing the cookies properly. Placing the dough too close together can cause them to merge while baking, leading to irregular shapes. Ensure you leave adequate space on the baking sheet.
- Using the wrong type of peanut butter. Natural peanut butter without stabilizers might make the dough too oily or dry. Stick with a standard creamy peanut butter for the best consistency.
- Forgetting to preheat the oven. Baking in an unheated oven can lead to uneven baking. Be sure to give your oven time to reach the right temperature before starting.
Variations & Substitutions
While the original recipe is simple and satisfying as is, you might consider experimenting with the following variations. You could try adding a tsp of vanilla extract for extra flavor, or sprinkle in a few chocolate chips if you’re okay with adding a bit of sweetness. Chopped nuts can also be stirred in for added texture, enhancing the rich peanut butter experience.
Storage & Reheating
These cookies can be stored at room temperature in an airtight container. They will stay fresh for about a week. If you wish to keep them longer, you can refrigerate them for a couple of weeks or freeze them for several months. For reheating, place them in a microwave for a few seconds. This warms them up, softening the texture while keeping their charm intact.
