With Liliya!
Peanut butter cookies bring back the sweetest memories for me. My mom used to press them down with a fork in that criss-cross pattern, and I thought it was the most magical touch. When I learned you could make them with only three ingredients, I was hooked. These cookies are the kind of recipe that make you feel like a kid again, standing by the oven waiting for that irresistible peanut butter smell to fill the kitchen.

Ingredients Needed for 3 Ingredient Peanut Butter Cookies
- Peanut butter. Smooth peanut butter works best for even mixing, but you can use crunchy if you want added texture. Natural peanut butter is fine, just be sure to stir it well so the oil doesn’t separate.
- White sugar. Sweetens and helps the cookies get that slightly crisp edge. You can also substitute brown sugar for a softer, chewier cookie.
- Egg. The binding ingredient that holds the peanut butter and sugar together while giving structure.
How I Make 3 Ingredient Peanut Butter Cookies
(This is a quick overview of how I make 3 Ingredient Peanut Butter Cookies, with tips along the way. You’ll find the full ingredients & instructions in the recipe card below.)
- Preheat the oven. Set your oven to 350°F (175°C) and line a baking sheet with parchment paper.
- Mix the dough. In a medium bowl, stir together peanut butter, sugar, and egg until smooth and fully combined.
- Shape. Roll dough into 1-inch balls and place them on the baking sheet, leaving space between each.
- Press. Use a fork to press each cookie down in a criss-cross pattern — this gives them the classic peanut butter cookie look.
- Bake. Bake for 6–8 minutes, just until the bottoms are set and lightly golden. Don’t overbake, or they’ll turn crumbly.
- Cool. Let them rest on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
Expert Tips for 3 Ingredient Peanut Butter Cookies
Choose the right peanut butter. Creamy peanut butter works best for even mixing. Natural peanut butter can be used, but make sure it’s stirred well to avoid oily or dry dough.
Avoid overbaking. These cookies only need 6–8 minutes. If you bake them longer, they’ll become crumbly instead of chewy.
Make them uniform. Roll the dough into even 1-inch balls so the cookies bake at the same rate.
Use a fork for pressing. The criss-cross pattern isn’t just traditional — it flattens the dense dough for even baking.
Cool on the sheet. Let cookies sit for a few minutes before moving them to a cooling rack. They’re very soft straight from the oven and need time to set.
Sweetness levels. If you prefer a less sweet cookie, reduce the sugar slightly, but keep enough to hold the structure.
Line with parchment paper. This prevents sticking and helps the bottoms bake evenly.
3 Ingredient Peanut Butter Cookies Variations and Substitutions
- Brown Sugar Peanut Butter Cookies. Replace white sugar with light brown sugar for a deeper caramel flavor and chewier bite.
- Crunchy Peanut Butter Cookies. Use crunchy peanut butter instead of smooth to add peanut bits for extra texture.
- Peanut Butter Chocolate Chip Cookies. Fold ½ cup of mini chocolate chips into the dough before baking.
- Keto Peanut Butter Cookies. Swap the sugar for erythritol, stevia blend, or monk fruit sweetener for a low-carb option.
- Nut-Free Peanut Butter Cookies. Replace peanut butter with sunflower seed butter. This creates a similar texture but keeps the recipe nut-free.
- Peanut Butter & Jelly Cookies. Press a thumbprint into the center before baking, and fill with your favorite jam after baking.
- Peanut Butter Sandwich Cookies. Spread frosting, Nutella, or even marshmallow fluff between two cookies for a fun twist.
- Chocolate Dipped Peanut Butter Cookies. Dip half of each cooled cookie in melted chocolate and let set for a pretty and indulgent treat.
- Salted Peanut Butter Cookies. Sprinkle a pinch of flaky sea salt on each cookie before baking for that perfect sweet-salty balance.
Storing / Freezing 3 Ingredient Peanut Butter Cookies

FAQs About 3 Ingredient Peanut Butter Cookies
Why do these cookies only need three ingredients?
Peanut butter provides fat and protein, sugar adds sweetness and structure, and the egg binds it all together. No flour needed!
Do I have to use white sugar?
No, you can use brown sugar for chewier cookies or coconut sugar for a more natural option.
Can I use natural peanut butter?
Yes, but stir it thoroughly. If the dough feels too oily or loose, add an extra tablespoon of sugar.
Why do peanut butter cookies have fork marks?
The dough is dense and needs to be flattened before baking. The fork pattern helps them bake evenly and gives the classic peanut butter cookie look.
Do they spread in the oven?
Not much. That’s why pressing them with a fork is important.
