You’re in luck today — I’m sharing my version of the best peanut butter cookies: black-bottom triple peanut butter cookies. Inspired by a friend’s solid recipe, I intensified the peanut flavor and added a chocolate “black bottom” for balance.
The cookies turned out great! Thank you! Have tried 3-4 of your recipes, always amazing!

Why These Cookies are So Excellent
Peanut butter lovers — these cookies are built for you. I layered three peanut elements to maximize flavor without overwhelming texture:
- Natural peanut butter for intensity and creaminess.
- Peanut butter powder to deepen peanut flavor and add texture.
- Finely chopped peanut brittle for crunch and caramelized peanut notes.
Beyond ingredients, a long rest in the refrigerator overnight is what elevates the cookie. Chilling improves flavor melding, hydrates flour for better chew, helps sugar dissolve into the dough, and allows fats to firm up to prevent overspreading.
Pro-Tip
Chilling cookie dough concentrates flavor as some moisture evaporates and improves texture. Even an hour helps; overnight or up to a couple of days is ideal. This step can transform a good cookie into a great one.
How to Make Them
Ingredients
What you’ll need:
- Butter: 1 stick unsalted (the peanut butter supplies a lot of fat).
- Sugar: granulated for sweetness and browning.
- Brown sugar: adds moisture and depth; dark or light is fine.
- Optional syrup: 1 tablespoon sorghum, honey, or maple syrup for a hint of complexity.
- Vanilla extract: rounds the flavors.
- Salt: use kosher salt; peanut cookies benefit from a good pinch.
- Egg: 1 large at room temperature for structure and browning.
- Natural peanut butter: 1 cup (or your favorite peanut butter).
- Baking soda: balances acidity and aids spread.
- Peanut powder: about 1 oz to reinforce the peanut taste.
- All-purpose flour: about 1 cup (5 oz) for structure.
- Chopped peanut brittle: ~3 oz, finely chopped for crunch.
- For rolling: granulated sugar mixed with a bit of fine sea salt.
- For the black bottoms: 1–1½ cups coating chocolate (dark or milk) or chocolate chips plus about 10% coconut oil by weight.
Procedure
This is a creaming-method cookie and is straightforward:
- Cream the butter, sugars, optional syrup, vanilla, and salt until smooth.
- Beat in the egg until incorporated.
- Add the peanut butter, peanut powder, and baking soda; mix another minute.
- Mix in the flour on low speed until just combined.
- Stir in the chopped peanut brittle by hand.
- Wrap the dough and refrigerate at least 1 hour or up to 2–3 days.
To Bake
Portion dough into even pieces about 3/4 ounce (roughly 1 1/2 tablespoons) — a 1.5 tablespoon scoop works well. This batch yields about 40 cookies.
Rolling in Sugar
Mix granulated sugar with a touch of fine sea salt for rolling. Roll dough into balls, coat in the sugar mixture, place on lined baking sheets about 1½” apart, flatten slightly, then press a crosshatch with a fork.
Pro tip: Put the sugar mixture in a large zip-top bag, drop in a few dough balls, and shake to coat for minimal mess.
You’ll need three half-sheet pans; if you only have two, cool a hot pan under cold water for a few seconds before reusing. Bake at 350°F with racks in the upper and lower thirds: bake 5 minutes, rotate racks and pans, then bake another 5–7 minutes until edges are golden. I baked mine about 11 minutes total.
For the Black Bottoms
Melt coating chocolate or chips with about 10% of the chocolate weight in coconut oil to make a glossy, easy-to-spread coating that sets without tempering. Spread a thin layer on the bottoms of completely cooled cookies with a small offset spatula. Place on Silpat or parchment until set, about 15 minutes. If you used parchment, place chocolate side up to avoid any sticking risk.
I just made these cookies and we are inhaling them! I used all the accoutrements and the whole process was entirely enjoyable. Thank you so much! I’m off to share with neighbors!

Q & A
Yes. Substitute a flax egg (1 tbsp flax meal + 3 tbsp water, let thicken) if needed.
Yes. Swap almond butter or sunflower seed butter, use a compatible brittle or omit it, leave out peanut powder and add about 1 oz more flour.
No. The chocolate bottoms are optional. You can drizzle chocolate on top or skip it altogether.
Store tightly covered at room temperature for 4–5 days or freeze for longer storage.
Cool completely, place in freezer bags with air pressed out, and freeze up to 3 months. Thaw in the bag at room temperature.
More Goodies You May Enjoy!
For a simpler peanut butter cookie, try a recipe that uses browned butter and lots of peanut butter for a rich, roasted flavor. If you prefer other classic treats, try chewy sugar cookies or a peanut butter mousse pie for an intense, airy peanut dessert. For breakfast lovers, peanut butter sweet rolls pair perfectly with coffee.
A Note About Measurements
I write most recipes by weight for accuracy. A kitchen scale makes baking more reliable and cleanup faster — it’s a worthwhile investment for consistent results.
The Best Peanut Butter Cookies in the World
Ingredients
For the cookies
- 4 oz (1 stick) unsalted butter, cool room temperature
- 3.5 oz granulated sugar (about 1/2 cup)
- 3.5 oz packed dark brown sugar (about 1/2 cup)
- Optional 0.75 oz (1 tbsp) sorghum, honey, or maple syrup
- 2 tsp vanilla extract
- 1/2 tsp kosher salt
- 1 large egg, cool room temperature
- 9 oz (about 1 cup) natural peanut butter
- 1 oz peanut powder (about 1/3 cup)
- 1/2 tsp baking soda
- 5 oz (about 1 cup) all-purpose flour
- 3 oz finely chopped peanut brittle
To finish and bake
- 1 cup granulated sugar (for rolling)
- 1/2–3/4 tsp fine sea salt (mix with sugar)
For the black bottoms
- 1–1½ cups dark or milk coating chocolate or chips plus ~10% coconut oil by weight
Instructions
- Cream butter until smooth. Add sugars, optional syrup, vanilla, and salt; cream until uniform.
- Beat in the egg, scraping the bowl as needed.
- Mix in peanut butter, peanut powder, and baking soda until combined.
- Beat in flour on low speed until just combined. Stir in chopped peanut brittle by hand.
- Wrap dough and refrigerate at least 1 hour or overnight.
To finish and bake
- Preheat oven to 350°F and arrange racks in upper and lower thirds. Line three sheets with parchment.
- Mix sugar and fine salt in a large zip-top bag. Portion dough into 3/4 oz pieces (about 1″ diameter balls), roll in sugar-salt mixture, place on sheets 1½” apart, flatten slightly, and make a fork crosshatch.
- Bake in upper and lower thirds for 5 minutes, rotate pans and racks, then bake 5–7 more minutes until edges are golden. Cool on sheets 1–2 minutes, then transfer to racks to cool completely.
For the black bottoms
- When cookies are completely cool, melt coating chocolate with about 10% coconut oil by weight. Spread a thin layer on cookie bottoms with a small offset spatula. Place on Silpat or parchment until set, about 15 minutes. Store sealed at room temperature for a few days or freeze for longer storage.
Notes
If you bake two sheets first, move a rack to the center for the third or cool a hot pan under cold water before reusing. If you don’t have coating chocolate, melt 150 g chocolate with 15 g coconut oil as an easy coating. If you lack a Silpat, cool chocolate sides up on parchment.
