Ingredients You’ll Need
The beauty of this Flourless Peanut Butter Cookies (Gluten-Free) Recipe is in its simplicity—each ingredient is straightforward and plays a crucial role, whether it’s enhancing flavor, texture, or helping the cookies rise just right.
- 1 cup creamy peanut butter: The star player that provides richness, moisture, and that irresistible nutty taste.
- ¾ cup granulated sugar: Adds sweetness and helps create a slightly crisp cookie exterior.
- ¼ cup brown sugar (lightly packed): Brings a subtle caramel note and chewy texture to the cookies.
- 1 large egg: Binds all the ingredients together and adds structure.
- 1 teaspoon vanilla extract: Enhances the overall flavor and adds warmth.
- ½ teaspoon baking soda: Gives the cookies a slight lift and lightens the texture.
- ¼ teaspoon salt (optional): Balances sweetness, especially if using unsalted peanut butter.
How to Make Flourless Peanut Butter Cookies (Gluten-Free) Recipe
Step 1: Prepare Your Oven and Baking Sheet
Start by preheating your oven to 350°F—this ensures it’s hot and ready when your dough is mixed. Line a baking sheet with parchment paper to prevent sticking and to help the cookies bake evenly.
Step 2: Mix Ingredients Thoroughly
In a medium bowl, combine the creamy peanut butter, granulated sugar, brown sugar, egg, vanilla extract, baking soda, and salt if using. Stir everything until the mixture is smooth and all ingredients are fully blended. This uniformity is key to getting that classic peanut butter cookie texture.
Step 3: Form Your Cookies
Using a tablespoon, scoop out portions of dough and roll them into balls. Arrange these on your prepared baking sheet, spacing them about 2 inches apart to give the cookies room to spread as they bake.
Step 4: Create the Signature Crisscross
Gently flatten each cookie ball with a fork, pressing down to create a crisscross pattern. This step not only adds charm but helps the cookies cook evenly and achieve a perfect texture.
Step 5: Bake Until Perfect
Bake in the preheated oven for 9 to 11 minutes, watching closely for the edges to set and the top to start cracking. This indicates the cookies are baked through but still tender inside.
Step 6: Cool and Enjoy
Allow the cookies to cool for about 5 minutes right on the baking sheet—this helps them firm up. Then transfer them to a wire rack to cool completely, ensuring they keep their delicate texture without becoming soggy.
How to Serve Flourless Peanut Butter Cookies (Gluten-Free) Recipe

Garnishes
A simple sprinkle of flaky sea salt on top just before baking can elevate the sweet and savory contrast beautifully. For a bit more indulgence, consider drizzling melted dark chocolate or adding a few mini chocolate chips on top after baking for that extra wow factor.
Side Dishes
These cookies pair wonderfully with a cold glass of milk (dairy or plant-based) or a warm cup of coffee or tea. Their rich peanut buttery flavor balances perfectly with creamy or slightly bitter beverages, creating a truly comforting treat.
Creative Ways to Present
Serve these cookies stacked with a dollop of whipped cream and fresh berries for a quick dessert. You can also sandwich them with a layer of chocolate ganache or your favorite jam for fun, bite-sized cookie sandwiches that will impress guests.
Make Ahead and Storage
Storing Leftovers
Store your leftover Flourless Peanut Butter Cookies (Gluten-Free) Recipe in an airtight container at room temperature. They’ll stay fresh and chewy for up to a week, making them perfect for quick snacking throughout the week.
Freezing
If you want to keep these cookies longer, freezing is a great option. Arrange them in a single layer on a baking sheet to freeze initially, then transfer to a freezer-safe bag or container. They can be frozen for up to three months without losing their deliciousness.
Reheating
To bring back that fresh-baked warmth, pop the cookies in a preheated oven at 300°F for about 5 minutes or microwave them for 10 to 15 seconds. This revives their soft center and makes the peanut butter aroma even more inviting.
