Three ingredients. One bowl. No mixer, no flour, no chilling the dough. These 3-ingredient peanut butter cookies are done from start to finish in under 20 minutes — and they’re so good that nobody needs to know how easy they were.
Peanut butter. Sugar. One egg. That’s it. The recipe has been around forever and it keeps coming back because it actually works. The cookies come out with crispy edges, a slightly chewy center, and that deep peanut butter flavor that makes people reach for a second one before the first is finished.
They’re naturally gluten-free. They’re the easiest thing you can make with your kids. And they require zero equipment that you have to wash afterward except one bowl and a fork.
Christie’s take: My kid requests these constantly. I’ve made them at 8 p.m. when I’d promised cookies and had nothing to show for it. From pantry to plate in 18 minutes. This recipe has saved me more times than I can count.
Roll, press, bake. The whole recipe fits on one baking sheet.
🥜 The 3 Ingredients
1 cup peanut butter
Creamy works best for even mixing. Use good natural peanut butter if you have it — the flavor is noticeably better. Avoid the no-stir varieties with added oils, they make the cookies spread too much. Standard Jif or Skippy works perfectly fine.
1 cup granulated sugar
Plain white sugar. Some people swap half for brown sugar to get a chewier cookie with deeper flavor — both work. You can also reduce to ¾ cup if you prefer less sweet, though the texture changes slightly.
1 large egg
The egg binds everything together and gives the cookies structure. Room temperature is ideal but straight from the fridge works fine. This is the only ingredient that actually matters for the science — don’t skip it.
In a medium bowl, stir together the peanut butter, sugar, and egg until a thick dough forms. It will come together quickly — about 30 seconds of stirring. The dough will look almost too thick. That’s right.
3
Roll and place
Scoop about 1 tablespoon of dough (a cookie scoop makes this fast and even) and roll into a ball. Place on your prepared baking sheet about 2 inches apart. This recipe makes roughly 24 cookies.
4
Press the crosshatch
Use a fork to flatten each ball with a crosshatch pattern — press once, rotate 90 degrees, press again. This is the classic peanut butter cookie look and it also flattens the cookies to the right thickness for even baking. This is the job kids love.
5
Bake and cool
Bake for 10–12 minutes until the edges are just set and the tops look slightly underdone. They will firm up as they cool — don’t overbake. Let them sit on the baking sheet for 5 minutes before moving to a cooling rack. They’re fragile straight from the oven.
The fork-pressing step is the one kids ask to do every single time. Let them.

💡 Tips, Variations & Storage
Add a pinch of salt
Technically a 4th ingredient, but a pinch of flaky salt on top right before baking takes these from good to actually great. Salt and peanut butter are one of the best flavor combinations in baking. Do it.
Mix-in ideas
The base recipe is intentionally simple — which makes it a good canvas. Stir in a handful of chocolate chips, a teaspoon of vanilla extract, or a tablespoon of cocoa powder to make them different each time. All of these still only add one or two things to the bowl.
Don’t overbake
Pull them out when the edges look just barely set and the centers still look soft. They continue cooking on the hot pan for a few minutes after they come out. Overbaked peanut butter cookies go dry and crumbly fast — underbaked ones are chewy and perfect.
Make them gluten-free for company
These are naturally gluten-free as written — no flour means no gluten. If you’re baking for someone with celiac disease, just confirm your peanut butter is certified GF (most natural peanut butters are, but some processed brands share equipment).
Storage
Store in an airtight container at room temperature for up to 5 days. They also freeze beautifully — freeze baked cookies in a single layer, then transfer to a bag. Thaw at room temperature for 20 minutes or microwave for 15 seconds.
👧 Why This Is the Perfect Recipe to Make with Kids
There’s no hot stove involved until the oven (which you handle). The dough comes together with a spoon — no mixer to supervise. Rolling the balls and pressing the fork pattern are easy, satisfying tasks that even a 3-year-old can help with. And the payoff — warm cookies in 12 minutes — is fast enough to hold a kid’s attention.
This is one of the few recipes where the mess is minimal, the steps are genuinely kid-sized, and the result is something they’ll be proud of. Save it for a slow Saturday morning when you have 20 minutes and want to feel like a good-day mom.

3-Ingredient Peanut Butter Cookies — Questions Answered
Why do peanut butter cookies only need 3 ingredients?
Peanut butter already contains fat, protein, and binding properties that normally require butter and flour to achieve in a cookie. When you add sugar for sweetness and an egg for structure, you have everything you need. The fat in the peanut butter gives you the crispy edges; the protein gives you the chew; the egg holds it all together.
Are 3-ingredient peanut butter cookies gluten-free?
Yes — there’s no flour in this recipe, so the cookies are naturally gluten-free as written. If you’re baking for someone with celiac disease or a gluten intolerance, check that your peanut butter brand is certified gluten-free, as some are processed in facilities shared with wheat products.
Can I use crunchy peanut butter instead of creamy?
Yes — crunchy peanut butter works and adds a nice texture. The cookies will have small peanut pieces throughout and a slightly more rustic look. Creamy gives you a more uniform, smooth cookie. Both are good. Use whichever you have open.
Why are my peanut butter cookies falling apart?
The most common reason is moving them too soon after baking — these cookies are very fragile straight from the oven and need to sit on the pan for at least 5 minutes before you touch them. If they’re falling apart after cooling, you may have overbaked them slightly. Next batch, pull them out a minute earlier than you think you need to.
How many cookies does this recipe make?
Using 1 tablespoon of dough per cookie, this recipe makes about 24 cookies. If you make them slightly larger (1.5 tablespoons) you’ll get around 16. The bake time stays roughly the same — just watch for the edges to set and the tops to lose their shine.
The Recipe That’s Always in Your Pantry
The best thing about 3-ingredient peanut butter cookies is that you almost always have what you need. No special trip to the store, no planning ahead, no complicated steps. Just one bowl, three things, and 20 minutes.
Keep this recipe saved somewhere easy to find. It’s the one you’ll reach for when you need a quick dessert for company, a rainy afternoon activity with the kids, or just a moment that feels like you made something — because you did.
