Quick 3-Ingredient Peanut Butter Cookies
These 3-ingredient peanut butter cookies come together in about 15 minutes with nothing more than peanut butter, sugar, and an egg. They’re soft in the middle with a salty-sweet chew.
No mixer, no flour, and no chilling unless you want extra thick cookies. If you have those three things in the kitchen right now, you can have warm cookies before the oven even cools down.
Why These Cookies Just Work
This recipe leans entirely on the peanut butter for richness and structure. Without flour, the peanut flavor stays bold and concentrated instead of getting lost in the background. The sugar melts just enough in the oven to create a crumb that’s tender at the center, while the egg pulls everything into a dough you can scoop and press.
The edges crisp up a little, the tops crack, and the fork marks hold their shape. They stay chewy for days on the counter, and the whole thing feels like a shortcut that doesn’t taste like one.
Ingredients
- 1 cup creamy peanut butter: use a no-stir commercial brand like Jif or Skippy; natural peanut butter with separated oil makes the dough too loose.
- 1 cup granulated sugar: plain white sugar works best here for texture.
- 1 large egg: straight from the fridge is fine.
Variations / Substitutions
- Brown sugar: swap up to half the granulated sugar with packed brown sugar for a softer, molasses-like chew.
- Nut-free option: creamy sunflower seed butter works, but the cookies may spread more; add 2 tbsp oat flour to the dough if needed.
- Mix-ins: fold in 1/2 cup chocolate chips or chopped roasted peanuts right after mixing the dough.
- Less sweet: use an unsweetened, no-stir peanut butter and reduce sugar to 3/4 cup; the texture will be slightly drier.

How to Make Quick 3-Ingredient Peanut Butter Cookies
Step 1: Mix the Dough
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. In a large bowl, stir together the 1 cup peanut butter, 1 cup sugar, and the egg until the mixture forms a thick, smooth dough with no streaks. This takes about a minute by hand, and the dough will look a little oily around the edges, which is exactly what you want.
Step 2: Scoop and Press the Cookies
Scoop rounded tablespoonfuls of dough and roll them briefly between your palms into balls. Place them on the prepared sheet, leaving about 2 inches between each one. Dip a fork into a small bowl of granulated sugar, then press each ball in a crosshatch pattern, flattening the cookies to about half an inch thick. The sugar on the fork keeps it from sticking and adds a little extra crunch on top.
Step 3: Bake and Cool
Bake the cookies for 10 to 12 minutes, until they look puffed and the edges are set with a hint of gold. The centers will look a little underdone, which is fine. Let them rest on the sheet for 5 minutes so they firm up, then transfer to a wire rack to cool completely. They’ll be soft and chewy the whole way through.
A Few Notes for the Best Cookies
- Choose the right peanut butter. No-stir creamy peanut butter gives you a dough that holds its shape. If you use a natural peanut butter that separates, the cookies will spread into thin, lacy puddles.
- Don’t overbake. At the 10-minute mark the cookies should still look soft in the center; carryover heat on the sheet will finish setting them up.
- Toss in chocolate chips if you want a classic combo. A big pinch of flaky sea salt on top right after baking works wonders, too.
- These cookies are naturally gluten-free as long as your peanut butter is processed in a certified gluten-free facility.
Bake times for different textures:
| Texture | Time |
|---|---|
| Soft all the way through | 9-10 minutes |
| Chewy with a set edge | 10-11 minutes |
| Crispy edges, soft centers | 12 minutes |
Storing Leftover Cookies
- Room temperature: store baked cookies in an airtight container on the counter for up to 5 days. Slide a piece of bread into the container if they start to dry out.
- Freezing the dough: roll the dough into balls and freeze them on a tray. Once solid, move them to a zip-top bag. Bake straight from the freezer, adding 1-2 minutes.
- Freezing baked cookies: layer cooled cookies between sheets of wax paper in an airtight container and freeze for up to 3 months. Thaw at room temperature.
Frequently Asked Questions
Can I use natural peanut butter?
Natural peanut butter that separates isn’t a good swap here. The thinner, runnier consistency makes the dough spread too much and the cookies turn out flat and greasy. Stick with a no-stir brand.
Do I have to chill the dough?
No, you can scoop and bake right away. If you prefer thicker cookies that spread less, pop the bowl of dough in the fridge for 30 minutes before scooping.
Why did my cookies spread too much?
Usually it comes down to the peanut butter. Using natural peanut butter, measuring too loosely, or baking on a hot, greasy sheet can all cause excess spread. Line your pan with fresh parchment and stick with a classic creamy peanut butter.
Are these cookies gluten-free?
Yes, the dough has no flour, so it’s naturally gluten-free. Just check that your peanut butter is made in a facility that avoids cross-contamination if that matters to you.
