• Uses pantry staples you likely already have on hand
• Stays chewy: soft centers with lightly crisp, set edges
• Freezes beautifully: dough balls or baked cookies keep up to two months

Ingredients

• 1 cup unsalted butter, softened — room temp for easy creaming
• 1 cup creamy peanut butter — well-stirred for uniform texture
• 1 cup granulated sugar — fine grain dissolves evenly
• 1 cup packed light brown sugar — adds moisture and chew
• 2 large eggs, room temperature — incorporate more smoothly
• 2 teaspoons vanilla extract — pure, not imitation
• 2 cups all-purpose flour — measure with spoon-and-level
• 1/2 cup Dutch-process cocoa powder — for deep chocolate flavor
• 1 teaspoon baking soda — guarantees proper spread
• 1/2 teaspoon baking powder — boosts lift slightly
• 3/4 teaspoon fine sea salt — balances sweetness
• 1 1/2 cups dark chocolate chips — 60–70% cacao preferred
• 1/2 cup chopped roasted peanuts (optional) — adds crunch and nuttiness
• 2 tablespoons milk (optional, as needed) — moisten if dough seems dry
• Flaky sea salt for topping (optional) — sprinkle on hot cookies for contrast

Step-by-Step Method

Cream the Fats and Sugars

Beat softened butter, creamy peanut butter, granulated sugar, and brown sugar until pale and fluffy, about 2 minutes.

Scrape the bowl. Aerate well to promote lift and tender texture. Make certain no visible lumps remain. Proper creaming helps the cookies spread evenly while staying soft in the center.

Whisk the Dry Ingredients

Combine flour, Dutch-process cocoa powder, baking soda, baking powder, and fine sea salt in a separate bowl.

Whisk until uniform with no cocoa streaks. Break up clumps for even mixing later. This prevents overmixing the dough and makes certain consistent rise and chocolate flavor throughout.

Incorporate Eggs and Vanilla

Add eggs one at a time to the creamed mixture.

Beat well after each addition until fully emulsified. Mix in vanilla extract until smooth and glossy. Scrape down the bowl and beater. A well-emulsified base keeps cookies tender and prevents greasy pockets.

Combine Wet and Dry

Add dry ingredients to the wet mixture.

Mix on low just until the flour disappears. Avoid overmixing to reduce toughness. If the dough seems dry or crumbly, drizzle in milk a tablespoon at a time. Aim for a soft, scoopable dough that holds shape.

Fold in Mix-Ins

Gently fold in dark chocolate chips and chopped roasted peanuts, if using.

Distribute evenly without overworking the dough. Keep the mix-ins suspended so each cookie has bits of chocolate and crunch. Chill the dough 20 to 30 minutes for thicker cookies, if desired.

Portion and Flatten

Preheat oven to 350°F (175°C). Line baking sheets with parchment.

Scoop 1.5-tablespoon mounds using a cookie scoop. Space about 2 inches apart for proper spread. Gently flatten each mound slightly with fingertips or the bottom of a glass for even baking.

Bake to Doneness

Bake one sheet at a time for 9 to 11 minutes.

Look for set edges and slightly soft centers. Remove promptly to avoid overbaking. Sprinkle flaky sea salt immediately, if using, for contrast. Cool on the sheet 5 minutes to set structure without overbaking.

Cool and Set

Transfer cookies to a cooling rack.

Let rest about 15 minutes until set and easy to handle. The centers will finish cooking on the rack, yielding a chewy, fudgy texture. Serve warm for melty chips or at room temperature for neat edges and clean bites.

Ingredient Swaps

• Gluten-free: Substitute the all-purpose flour with a 1:1 gluten-free baking flour blend; add 1–2 teaspoons milk if the dough seems dry.
• Dairy-free: Use vegan butter and dairy-free dark chocolate chips; omit milk or use a plant milk as needed.
• Peanut-free: Swap creamy peanut butter with almond, cashew, or sunflower seed butter (well-stirred); consider adding 1–2 tablespoons extra flour if dough is too loose.
• Cocoa: Natural cocoa can replace Dutch-process; add 1/4 teaspoon espresso powder to boost chocolate flavor (optional).
• Sugar: Use coconut sugar in place of brown and granulated sugars for a less refined option (cookies may be slightly less chewy).
• Mix-ins: Replace dark chips with chopped dark chocolate, milk or white chips, or budget-friendly baking chunks; swap peanuts with toasted seeds for nut-free crunch.

You Must Know

Doneness • If edges look set but centers seem puffy and matte, pull the tray once a few surface micro-cracks appear and the centers wobble slightly; carryover heat finishes them in 5 minutes on-sheet for a fudgy center without drying.

Troubleshoot • If dough feels greasy and spreads too much, chill 20–30 minutes and add 1 tablespoon flour; warmer butter or natural PB oils loosen structure—cooling re-firms fats and the small flour bump raises viscosity.

Swap • For natural peanut butter, stir thoroughly and add 1–2 teaspoons cornstarch per cup of flour; it compensates for lower emulsifiers, yielding thicker cookies with cleaner edges while keeping tenderness.

Scale • For 12 cookies, use half of every ingredient and keep scoop size (1.5 tbsp); time stays the same (9–11 minutes) because thickness, not batch size, drives doneness.

Flavor Boost • Toast the cocoa: sift, then warm it in a dry skillet over low heat 2–3 minutes until aromatic; enhances chocolate depth. Finish with 2–3 flakes of Maldon per cookie right out of the oven for contrast.

Serving Tips

• Serve warm with cold milk or lightly sweetened oat milk.
• Plate with vanilla ice cream and a drizzle of warm peanut butter.
• Pair with hot coffee or espresso; sprinkle extra flaky salt before serving.
• Crumble over chocolate pudding or yogurt parfaits for texture.
• Gift in cellophane bags tied with ribbon and a salt packet.

Storage & Make-Ahead

Store cookies in an airtight container at room temperature for 3–4 days.

Refrigerate for up to 1 week.

For make-ahead, scoop dough balls and chill 24–48 hours to deepen flavor.

Freeze dough balls or baked cookies for up to 2 months.

Bake frozen dough, adding 1–2 minutes.

Thaw baked cookies at room temperature.

Reheating

Reheat gently: microwave 8–12 seconds per cookie.

Oven at 300°F for 4–6 minutes on a sheet.

Stovetop skillet on low, covered, 1–2 minutes per side to refresh softness.

Bake Sale Classic Cameo

Fresh from a gentle warm-up, these cookies steal the spotlight at any bake sale like little velvet moons—dark, glossy, and freckled with flaky salt.

I tuck them into a parchment-lined tin, and the scent of cocoa and roasted peanuts drifts out like a whisper that says, “Come closer.” Kids point at the crinkly tops; grown-ups hover, eyes softening at the sheen of melted dark chips.

I price them simply—two for a dollar—and stack them in staggered rows so the salt catches the light.

One bite sells the next: tender edges, a fudgy center, and that peanut butter hum, warm and nutty.

If you’re stocking a table, I suggest a handwritten card and a bowl of samples—small quarters that guarantee a quick sell-out.

Final Thoughts

Give these dark chocolate peanut butter cookies a try and let me know your favorite spin—extra flaky salt, a mix of chips and chunks, or a handful of roasted peanuts.

Bake a batch, tweak to taste, and enjoy every gooey, chocolaty bite!

Frequently Asked Questions

Can I Make These Cookies Gluten-Free With Alternative Flours?

Yes—you can. I swap the all-purpose flour for a 1:1 gluten-free blend with xanthan gum. I add a splash of milk if dry. The dough feels sandy, then bakes into tender, fudgy, peanutty moons.

How Do I Adjust for High-Altitude Baking Conditions?

Reduce sugar 1–2 tablespoons, increase flour 1–2 tablespoons, add 1–2 teaspoons extra milk, and shorten bake time slightly. I watch edges set like mountain sunsets, smell cocoa bloom, and pull them soft, letting crisp air finish.

Are These Cookies Safe for Dogs or Pets?

No—they’re unsafe for dogs. I keep these human-only: dark chocolate, sugar, and salt whisper danger to pets. For your pup, I’d bake plain peanut butter treats, warm and nutty, with no chocolate, xylitol, or excess salt.

What’s the Best Way to Ship These Without Crumbling?

Pack them snug: I layer cooled cookies between parchment in a tin, bubble-wrap the tin, then box with filler. I ship fast, cool days, fragile-marked. They arrive like warm hugs—whole, tender, and deliciously intact.

Can I Reduce Sugar Without Affecting Texture Too Much?

Yes—trim sugar by 20–25% without major texture loss. I’ll bolster moisture with 1–2 tablespoons milk, add extra vanilla, and a pinch more salt. The dough stays tender; cocoa blooms, peanut butter hums, chocolate pools warmly.
