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 that when you place your cookies in, they will bake evenly and come out with a golden edge. As the oven heats, prepare your baking sheet by leaving it ungreased to allow for the perfect cookie slide later.
Step 2: Mix Ingredients
In a large mixing bowl, combine 1 cup of creamy or chunky peanut butter, 1 cup of sugar, and 1 egg. Using a wooden spoon, gently mix until the ingredients are just combined, taking care not to overmix. You want a thick and slightly sticky dough that's well-blended but still maintains its texture.
Step 3: Form the Dough
With the dough ready, scoop out golf ball-sized portions and place them on the ungreased baking sheet, spacing them about 2 inches apart. Using the tines of a fork, gently press down each ball to create a cross-hatch pattern, flattening them slightly. This will help the cookies bake evenly and give them that classic look.
Step 4: Bake the Cookies
Carefully place the baking sheet in your preheated oven. Bake the cookies for 8 to 10 minutes or until the edges are lightly golden. Keep an eye on them; they should be set but still slightly soft in the center, as they will continue to firm up while cooling.
Step 5: Cool Before Transferring
Once baked, remove the cookies from the oven and let them cool on the baking sheet for at least 5 minutes. This resting time allows them to firm up, making it easier to transfer them without breaking. The cookies will have that wonderful warm, nutty aroma that fills your kitchen.
Step 6: Transfer to a Cooling Rack
After cooling slightly, use a spatula to gently transfer the peanut butter cookies to a cooling rack. Allow them to cool completely before enjoying. This final step is crucial for the best chewy texture, so resist the temptation to indulge right away.

Make Ahead Options
These 3 Ingredient Peanut Butter Cookies are fantastic for busy home cooks who want to savor homemade treats without the last-minute rush! You can prepare the cookie dough up to 24 hours in advance; simply mix the ingredients and refrigerate them in an airtight container. For even more convenience, scoop the dough into golf ball-sized portions and freeze them individually on a baking tray. Once frozen, transfer the dough balls to a zip-top bag, and they can be stored for up to 3 months. When you’re ready to bake, just preheat your oven and bake the frozen cookie dough for an additional minute or two until they’re golden and chewy. This way, you'll enjoy freshly baked 3 Ingredient Peanut Butter Cookies with minimal effort!
How to Store and Freeze Peanut Butter Cookies
Room Temperature: Store your cookies in an airtight container at room temperature for up to 1 week. Place parchment paper between layers to keep them from sticking together.
Fridge: For extended freshness, you can refrigerate the cookies in an airtight container for up to 2 weeks, but note that they may become a bit firmer.
Freezer: Freeze the baked cookies in a zip-top bag for up to 3 months. Layer them with parchment paper to avoid sticking. Just thaw at room temperature before enjoying.
Make-Ahead Tip: You can also freeze the cookie dough balls; bake directly from the freezer, adding an extra minute or two to the baking time for perfectly fresh peanut butter cookies.

3 Ingredient Peanut Butter Cookies Recipe FAQs
How do I choose the right peanut butter?
Absolutely! A good peanut butter is key to these cookies. Choose a creamy peanut butter for a smooth texture or a chunky one for a delightful crunch. Always go for natural peanut butter with minimal ingredients for the best flavor—just peanuts and salt is ideal!
How should I store my cookies?
Very simply! Store your peanut butter cookies in an airtight container at room temperature for up to 1 week. Be sure to put parchment paper between layers to prevent them from sticking together and losing that delicious texture. If you're looking to keep them longer, refrigerating can extend their freshness to about 2 weeks!
Can I freeze the cookie dough or baked cookies?
Absolutely! Freezing is a great option. To freeze the cookie dough, scoop out the dough balls and place them on a baking sheet lined with parchment. Freeze for about 1-2 hours until firm, then transfer them to a zip-top bag. They can be stored this way for up to 3 months. When ready to bake, simply add an extra minute or two to the baking time from frozen. For baked cookies, layer them with parchment paper in a zip-top bag and freeze for up to 3 months as well. Just thaw at room temperature before enjoying!
What should I do if my cookies come out too dry?
If you find your cookies dry, it might be due to overmixing or overbaking. Make sure to mix just until combined and check your cookies a minute or two earlier than the suggested bake time. If they seem dry, you can also try adding a bit more peanut butter or a touch of oil next time to keep them moist.
Can I make these cookies vegan?
Yes, you can! To make vegan peanut butter cookies, just replace the egg with flaxseed meal. Mix 1 tablespoon of flaxseed meal with 2.5 tablespoons of water and let it sit for about 5 minutes until it thickens. This works as an excellent binder in place of the egg without sacrificing any of that rich peanut flavor!
