It started with a craving — the kind that lands somewhere between a rich brownie and a soft-baked cookie. I was halfway through stirring up a classic chocolate cookie dough when I spotted the jar of peanut butter on the counter, left from a sandwich earlier that afternoon. You know how it goes: one glance turned into an idea I couldn’t shake.
So I scooped a spoonful, swirled it gently into the chocolatey dough, and hoped for magic. When the cookies came out of the oven — slightly crackled on top, gooey in the center, and streaked with golden ribbons of peanut butter — I knew I’d hit on something special.
These cookies are indulgent without being fussy. Fudgy like a brownie, chewy like a cookie, and layered with that salty-sweet swirl that peanut butter fans will fall hard for.
Short Description
These Swirled Brownie Cookies With A Peanut Butter Twist are soft, rich, and chewy with a fudgy chocolate base and luscious peanut butter swirls — perfect for dessert lovers who can’t decide between a brownie and a cookie.
Key Ingredients
- 1 cup semi-sweet chocolate chips
- ½ cup unsalted butter (1 stick)
- ¾ cup granulated sugar
- ¼ cup brown sugar
- 2 large eggs
- 1 tsp vanilla extract
- ¾ cup all-purpose flour
- ¼ cup unsweetened cocoa powder
- ½ tsp baking powder
- ¼ tsp salt
- ⅓ cup creamy peanut butter (not natural style)
Tools Needed
- Mixing bowls
- Saucepan or microwave-safe bowl
- Whisk or electric mixer
- Baking sheet
- Parchment paper
- Cookie scoop or tablespoon
Baking Instructions
Step 1: Melt chocolate and butter
In a saucepan or microwave-safe bowl, melt the chocolate chips and butter together until smooth. Let it cool for 5 minutes.
Step 2: Whisk in sugars and eggs
Stir in granulated sugar, brown sugar, eggs, and vanilla extract until the mixture is thick and glossy.
Step 3: Mix dry ingredients
In a separate bowl, whisk together flour, cocoa powder, baking powder, and salt. Gradually fold into the chocolate mixture until just combined.
Step 4: Swirl in peanut butter
Drop small dollops of peanut butter over the cookie dough. Use a knife or spatula to gently swirl it in — don’t overmix. You want thick ribbons of peanut butter, not a fully blended dough.
Step 5: Chill the dough
Chill the dough in the fridge for 20–30 minutes. This helps the cookies hold their shape while baking.
Step 6: Bake
Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper. Scoop 1.5 tablespoon-sized balls of dough onto the sheet, leaving space between each. Bake for 9–11 minutes, just until the tops are crackly and the centers are soft.
Step 7: Cool and enjoy
Let cookies cool on the pan for 5 minutes, then transfer to a wire rack. Enjoy warm or store for later!

Mistakes to Avoid & Solutions
1. Overbaking
→ Solution: Pull them out when the centers still look slightly underdone. They’ll firm up as they cool.
2. Peanut butter disappearing
→ Solution: Swirl gently and don’t overmix — you want bold ribbons, not blended-in flavor.
3. Cookies spreading too much
→ Solution: Chill the dough for at least 20 minutes before baking.
4. Using natural peanut butter
→ Solution: Stick to classic creamy PB (like Jif or Skippy). Natural ones are too oily and separate in the oven.
