Chewy Brown Butter Peanut Butter Cookies
These brown butter peanut butter cookies get a deep, nutty layer of flavor from toasted butter and plenty of creamy peanut butter. They bake up thick and chewy, with crisp edges that crackle when you bite.
No chilling, no stand mixer, just a little patience while the butter browns. The extra five minutes on the stove makes the whole kitchen smell like roasted nuts and melted sugar.
What Makes These Chewy Cookies Work So Well
Brown butter does two things at once. It adds a toasty, hazelnut depth that flatters the peanut butter, and the warm fat helps dissolve the sugars so the tops get that thin, shiny crackle.
I use a shelf-stable peanut butter (the sweetened kind, not natural) because it keeps the dough soft without needing extra oil. The centers stay tender and the edges set just enough to hold the cookie together.
Ingredients
- 1/2 cup (113 g) unsalted butter: you will brown it, so start with cold or room temp, either is fine.
- 3/4 cup (150 g) light brown sugar, packed: gives the chew and a soft molasses note.
- 1/4 cup (50 g) granulated sugar: helps the edges crisp.
- 1 large egg, at room temperature: cold egg can firm the butter too fast, so pull it out early.
- 1 tsp vanilla extract
- 3/4 cup (190 g) creamy peanut butter: use a commercial brand like Jif or Skippy. Natural peanut butter can separate and make the dough oily.
- 1 1/4 cups (160 g) all-purpose flour
- 1/2 tsp baking soda
- 1/2 tsp fine sea salt
- Flaky sea salt, for sprinkling (optional)
Variations / Substitutions
- Dark brown sugar: swap the light brown sugar for dark brown for a stronger molasses taste.
- Crunchy peanut butter: replace the creamy peanut butter with crunchy for extra peanut pieces in every bite.
- Chocolate chips: stir 1/2 cup semisweet or dark chocolate chips into the dry ingredients.
- Dairy-free: use a vegan butter that browns (like Miyoko’s) and a flax egg.

How to Make Brown Butter Peanut Butter Cookies
Step 1: Brown the Butter
Cut the 1/2 cup unsalted butter into a few chunks and drop them into a light-colored saucepan. Melt over medium heat, then keep cooking, swirling the pan often. The butter will foam and sputter, then settle as the solids start to toast. In 3 to 5 minutes, it will turn amber and smell rich, like toasted hazelnuts. Small brown flecks at the bottom are exactly what you want.
Take the pan off the heat right away and pour the brown butter into a large heatproof mixing bowl. Scrape in every dark speck from the pan. Let it cool for 10 minutes, just until warm but not hot. You can stir it once or twice to help the heat escape.
Step 2: Mix the Wet Ingredients
Add the 3/4 cup light brown sugar and 1/4 cup granulated sugar to the cooled brown butter. Whisk vigorously until the mixture looks like wet sand and no sugar streaks remain. Crack in the 1 egg, then add the 1 tsp vanilla extract. Whisk again until smooth and glossy.
Spoon in the 3/4 cup peanut butter and switch to a sturdy spatula or wooden spoon. Beat it into the butter-sugar mixture until you have a thick, uniform paste. It should look like soft cookie dough already.
Step 3: Fold in the Dry Ingredients
Scoop the 1 1/4 cups flour into a medium bowl, then whisk in the 1/2 tsp baking soda and 1/2 tsp fine sea salt. Tip the dry mix into the wet ingredients all at once.
Fold with a spatula, scraping the bottom and sides, until no dry flour is visible. The dough will be soft and slightly sticky. Stop as soon as it comes together. Overworking the flour will make the cookies tough.
Step 4: Shape the Dough
Line two baking sheets with parchment paper. Scoop the dough by the tablespoon and roll each portion into a ball. You will get about 24 balls. Place them on the sheets 2 inches apart.
If you want the classic crosshatch look, press a fork dipped in a little sugar or flour into each ball, once horizontally and once vertically. You can skip this and the cookies will still spread into thick rounds.
While you shape the dough, preheat the oven to 350°F (175°C) so it is ready the moment you finish.
Step 5: Bake and Finish
Slide the first sheet into the hot oven and bake for 10 to 12 minutes. The cookies are done when the edges are set and lightly golden, and the centers look puffy and crackly. They will still be soft in the middle, which is what you want for chewiness.
Pull the sheet from the oven and immediately tap a tiny pinch of flaky sea salt onto each warm cookie if using. Let them rest on the sheet for 5 minutes before moving to a rack. The centers will sink and crinkle as they cool. Serve them warm or at room temperature.
Tips for the Best Texture
- Measure the flour the baker’s way: spoon it into the cup and level with a knife. Too much flour makes dry, cakey cookies.
- Use a light-colored skillet to brown the butter. You can see the color change clearly, and it is less likely to burn without warning.
- A 30-minute chill firms the dough and gives you thicker, taller cookies. If you want them extra thick, roll the balls and pop the tray in the fridge while the oven heats.
- Sprinkle the flaky salt right after baking. It sticks to the warm surface and gives that salty-sweet bite.
Bake times shift a bit with cookie size:
| Size | Dough per cookie | Bake Time |
|---|---|---|
| Small | 1 tbsp | 8-10 minutes |
| Medium | 2 tbsp | 10-12 minutes |
| Large | 3 tbsp | 12-14 minutes |
Keeping Them Fresh
Store baked cookies in an airtight container at room temperature for up to 5 days. You can also freeze the unbaked dough balls on a tray, then bag them. Bake straight from frozen, adding 2 to 3 minutes to the time.
Frequently Asked Questions
Can I use natural peanut butter?
Natural peanut butter (the kind that separates) can work if you stir it very well until the oil is fully blended. The cookies will spread more and taste less sweet, but the peanut flavor will be strong.
How do I make these gluten-free?
Substitute a 1-to-1 gluten-free baking flour that contains xanthan gum. The texture will be a bit softer, but still good.
Can I freeze the dough?
Yes. Roll the dough into balls, freeze them solid on a sheet, then transfer to a freezer bag. Bake from frozen, adding 2 to 3 extra minutes. No need to thaw.
What if I only have salted butter?
That is fine. Omit the fine sea salt in the dry ingredients and still sprinkle flaky salt on top if you like the contrast.
Ingredients
Method
- Melt the butter in a light-colored saucepan over medium heat. Cook, swirling often, until amber with brown bits and a nutty smell, about 3 to 5 minutes. Pour into a large bowl to cool for 10 minutes.
- Whisk the cooled brown butter with both sugars. Add the egg and vanilla, then beat in the peanut butter until smooth.
- Fold in the flour, baking soda, and salt until no dry streaks remain, being careful not to overmix.
- Roll the dough into tablespoon-sized balls and place on parchment-lined sheets. Press with a fork for crosshatch marks if you like.
- Bake at 350°F (175°C) for 10 to 12 minutes, until edges are set and centers are puffy. Sprinkle with flaky salt warm, cool on the sheet 5 minutes, then transfer to a rack.
