Step‑by‑Step Instructions for 3 Ingredient Peanut Butter Cookies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures your cookies will bake evenly and achieve that perfect golden hue. While the oven warms up, prepare two baking sheets by lining them with parchment paper to prevent sticking and make cleanup a breeze.
Step 2: Mix the Ingredients
In a large mixing bowl, combine your peanut butter, sugar, and egg. Using an electric hand mixer, blend the ingredients on medium speed until the mixture is thoroughly combined and smooth, about 1-2 minutes. You want a consistent batter that showcases the rich, creamy texture of the peanut butter—a telltale sign you’re on the right track with these 3 ingredient peanut butter cookies.
Step 3: Form the Cookies
Using a tablespoon or a cookie scoop, drop rounded tablespoonfuls of the dough onto the prepared baking sheets, ensuring you leave about 2 inches of space between each cookie to allow for spreading. Flatten each dough ball gently with a fork, creating a delightful criss-cross pattern that adds a bit of character and ensures they bake evenly.
Step 4: Bake the Cookies
Carefully place the baking sheets in the preheated oven and bake for 9 to 11 minutes, or until you see the edges turning lightly golden. Keep an eye on them to avoid over-baking; you want that beautiful gold without losing the chewy texture distinctive of these 3 ingredient peanut butter cookies.
Step 5: Cool and Enjoy
Once baked, remove the cookies from the oven and let them cool on the baking sheets for about 5 minutes. This resting time allows them to firm up before transferring. Gently move the cookies to a wire rack to cool completely, which helps maintain their delicious texture while you patiently await their irresistible taste!

Make Ahead Options
These 3 Ingredient Peanut Butter Cookies are a fantastic treat for busy home cooks, and prepping them ahead of time saves you precious moments during hectic weeks! You can mix the dough and refrigerate it for up to 3 days in an airtight container—this also allows the flavors to meld beautifully. When you’re ready to bake, simply scoop and form the cookies as usual, then bake them fresh for about 9-11 minutes. If you’re in a hurry, you can also bake the cookies and store them in an airtight container for up to 1 week or freeze them for up to 3 months. Just make sure to let them cool completely before storing to maintain their delightful texture. Enjoy the convenience of homemade sweetness whenever you crave these delicious 3 Ingredient Peanut Butter Cookies!

Expert Tips for 3 Ingredient Peanut Butter Cookies
• Choose Your Peanut Butter: Use creamy or crunchy peanut butter based on your texture preference. Each will yield a delicious cookie, but they will have different bites.
• Perfect Sugar Balance: For thicker cookies, reduce sugar to ½ cup. This helps avoid overly thin cookies that may spread too much during baking.
• Consistent Size Matters: Use a cookie scoop to ensure uniform sizes. This will help your 3 ingredient peanut butter cookies bake evenly, resulting in a better texture.
• Watch the Bake: Keep an eye on the cookies during baking. Remove them when the edges are lightly golden to prevent over-browning, which can change the texture.

3 Ingredient Peanut Butter Cookies Recipe FAQs
What type of peanut butter should I use?
Absolutely! You can use either creamy or crunchy peanut butter based on what texture you prefer. Creamy gives you a smooth consistency, while crunchy adds little bits of peanut for extra bites of flavor. They both create delicious cookies, so pick your favorite!
How should I store my cookies?
To maintain their freshness, store your 3 Ingredient Peanut Butter Cookies in an airtight container at room temperature for up to one week. This keeps them soft and delectable. If you’d like to keep them longer, consider freezing them!
What’s the best way to freeze these cookies?
To freeze your cookies, start by allowing them to cool completely. Then, place them in a freezer-safe bag or container, gently separating layers with parchment paper to prevent sticking. They can be stored this way for up to three months. When you’re ready to enjoy, simply thaw at room temperature for about 30 minutes or pop them in the microwave for a few seconds until warm—perfectly gooey!
How can I prevent my cookies from being too thin?
If you’re looking for thicker cookies, I recommend reducing the sugar to ½ cup instead of ¾ cup. This helps achieve a denser texture. Additionally, using a cookie scoop can ensure uniform sizes, which aids in even baking and prevents excessive spreading!
Can I alter this recipe for dietary restrictions?
Definitely! If you’re looking for alternatives, you can substitute peanut butter with almond or cashew butter—just keep in mind that the flavor will change slightly. For egg-free cookies, try using a flax egg (1 tablespoon of flaxseed meal mixed with 2.5 tablespoons of water) as a binder. This will keep the cookies vegan and still delicious!
How do I know when my cookies are done baking?
Keep an eye on your cookies while they bake—removing them when the edges are lightly golden is key! The centers should look a little soft but will firm up as they cool. If they start to turn dark, they may lose that memorable chewy texture we adore!
