The 3-Ingredient Peanut Butter Cookies You'll Make Every Week

Here's the thing that surprises people: peanut butter is doing the job of both the fat AND the flour in this recipe. It's packed with protein and natural oils that give the cookie structure and richness without needing any grain at all. The egg is your binder — it pulls everything together and gives the cookie a proper chew. Get the mixing right (cream the peanut butter and both sugars until the mixture lightens just a little before adding the egg) and you'll have a smooth, cohesive dough that bakes up beautifully. Skip that step and the texture can turn dense and crumbly. One more thing: peanut butter dough is thick and doesn't spread much on its own, so that fork press isn't just for the classic look — it's actually flattening the cookie so the center bakes through evenly before the edges get too set. Press in both directions for uniform thickness.

These cookies skew sweet — that's just the nature of a sugar-forward dough with no salt built in. If your peanut butter is unsalted, you'll really notice it. The fix is dead simple: grab some flaky sea salt and sprinkle a tiny pinch on each cookie right before they go into the oven. It wakes everything up, balances the sweetness, and makes the peanut flavor pop. It's a two-second move that makes a genuinely noticeable difference. Don't skip it.

With only three real ingredients, the quality of each one shows up directly in the final cookie. For peanut butter, go natural and stir-type if you can — the kind where the oil separates and you have to mix it. Commercial brands load in extra sugar and hydrogenated fat, which throws off the balance of the whole recipe. For the brown sugar, make sure it's fresh and soft. If it's dried out and clumping, it won't cream properly and your dough will be crumbly instead of smooth. Fresh, moist brown sugar is the difference between a cookie that spreads just right and one that bakes up like a hockey puck.

Once you've got the base down, this recipe is a great canvas to play with. Press a chocolate chip or two into each ball before baking for a peanut butter–chocolate situation. Swap the peanut butter for almond butter or sunflower seed butter and the whole flavor profile shifts — still works beautifully. You can also roll the dough balls in a little extra granulated sugar before pressing them for a slightly crispier, sparklier exterior. And if you want to go richer, a teaspoon of cocoa powder mixed into the dough adds a subtle chocolatey depth that plays really nicely with the peanut butter.
