Step‑by‑Step Instructions for 3-Ingredient Gluten-Free Peanut Butter Cookies
Step 1: Preheat Your Oven
Begin by preheating your oven to 350°F (175°C). This ensures a perfect baking environment for your 3-Ingredient Gluten-Free Peanut Butter Cookies. While the oven is heating, gather your baking sheets and line them with parchment paper, creating a non-stick surface for the cookies to rest on once formed.
Step 2: Mix the Ingredients
In a large mixing bowl, combine 1 cup of peanut butter, 1 cup of sugar, and 1 egg. Using a sturdy spoon or a hand mixer, stir the mixture until all ingredients are well blended and smooth, usually around 2-3 minutes. The dough will be thick and slightly sticky, which is perfect for shaping your cookies.
Step 3: Shape the Cookies
Once your dough is ready, use a tablespoon to scoop out portions and roll them into balls. Place these balls about 2 inches apart on your lined baking sheet. You should have enough for 12-15 cookies. This spacing allows for the cookies to spread while baking, ensuring even cooking and a delightful chewy texture.
Step 4: Create the Crisscross Pattern
To add a classic touch to your cookies, take a fork and gently press down on each dough ball to flatten it slightly. Then, make a crisscross pattern by pressing the fork down in the opposite direction. This not only creates a beautiful design but helps the cookies bake evenly, ensuring they are light and chewy.
Step 5: Bake to Perfection
Slide your baking sheet into the preheated oven and bake for 10-12 minutes. Keep an eye on your cookies; they will be ready when the edges turn golden brown but the centers remain soft. This slight underbaking gives you that perfect chewy texture characteristic of great peanut butter cookies.
Step 6: Cool and Enjoy
After baking, remove the cookies from the oven and let them cool on the baking sheet for about 5 minutes. This allows them to set up properly. Then, carefully transfer them to a wire rack to cool completely. Once they’ve cooled, enjoy your delightful 3-Ingredient Gluten-Free Peanut Butter Cookies with a glass of milk or coffee, savoring the sweet, nutty aroma that fills your kitchen!

Expert Tips for 3-Ingredient Peanut Butter Cookies
-
Room Temperature Peanut Butter: Ensure your peanut butter is at room temperature for easier mixing. Cold peanut butter can lead to a lumpy dough.
-
Watch the Baking Time: Do not overbake your cookies. They will continue to firm up as they cool, so aim for soft centers with golden edges for the best texture.
-
Even Spacing: When placing dough balls on the baking sheet, give them enough space (about 2 inches apart) to allow for spreading while baking. This helps to achieve a chewy cookie.
-
Extra Flavor: For added depth, consider mixing in a pinch of salt or a splash of vanilla extract. This can elevate the delicious taste of your 3-ingredient cookies.
-
Cooling Is Key: Allow cookies to cool on the baking sheet before transferring them to a wire rack. This prevents them from breaking apart and ensures they set properly.
How to Store and Freeze 3-Ingredient Peanut Butter Cookies
Room Temperature: Store cookies in an airtight container at room temperature for up to 7 days. This keeps them soft and fresh, ready for snacking at any moment!
Fridge: If you prefer them chilled, you can refrigerate your cookies in an airtight container for up to 2 weeks—great for a refreshing treat on warm days.
Freezer: For longer storage, freeze the cookies for up to 3 months. Place them in a freezer-safe bag or container, separating layers with parchment paper to prevent sticking.
Reheating: To enjoy your cookies warm again, reheat them in the oven at 350°F (175°C) for about 5 minutes. You’ll be greeted with that deliciously fresh-baked aroma!

3-Ingredient Gluten-Free Peanut Butter Cookies Recipe FAQs
What type of peanut butter should I use?
Absolutely! You can use either smooth or crunchy peanut butter, depending on your texture preference. Smooth peanut butter will give you a more uniform cookie, while crunchy adds delightful bits of peanuts for a unique texture.
How should I store the cookies?
For the best freshness, store your cookies in an airtight container at room temperature for up to 7 days. This keeps them soft and chewy! If you’d like them to stay fresh for a bit longer, you can refrigerate them in an airtight container for up to 2 weeks.
Can I freeze the cookies?
Very! To freeze your cookies, let them cool completely first. Then place them in a freezer-safe bag or container, layering parchment paper between them to prevent sticking. They can be frozen for up to 3 months. When you’re ready to indulge, simply thaw them at room temperature or reheat in the oven for 5 minutes!
What should I do if my dough is too sticky?
If you find your dough is overly sticky, it could be due to the temperature of your peanut butter. Try chilling the dough for about 30 minutes before shaping the cookies. Alternatively, adding a little extra sugar can help stiffen the mixture.
Are these cookies safe for people with nut allergies?
Unfortunately, they aren’t safe for those with nut allergies, given the primary ingredient is peanut butter. As a substitute for a nut-free option, you could try sunflower seed butter, though it may alter the flavor slightly. Always check for any potential allergens if serving to guests.
