There’s something magical about peanut butter brownie swirl cookies — the way they bring two beloved classics, peanut butter cookies and rich brownies, together in one irresistible bite. I remember the first time I made these: it was a rainy autumn afternoon, and the kitchen smelled like childhood, nostalgia, and pure comfort. These cookies are the kind you bake when you want to wrap someone in a hug without saying a word.
Peanut butter brownie swirl cookies have a charming history rooted in the marriage of two great American dessert traditions. Peanut butter cookies, with their iconic fork-cross tops, have been around since the 1910s, while brownies have been gracing dessert tables since the early 1900s. Combining them into a swirl cookie creates not only a beautiful marbled pattern but also a balance of sweet, salty, fudgy, and nutty — a texture and flavor experience that’s hard to beat.
Whether you’re baking these for a holiday cookie platter, a weekend treat, or just to make a regular Tuesday feel a little special, they promise to win hearts and leave your kitchen smelling incredible.

INGREDIENTS YOU’LL NEED:
- 1 cup creamy peanut butter
- 1 cup granulated sugar
- 1 large egg
- 1/2 cup unsalted butter, softened
- 1/2 cup brown sugar, packed

How to Make Peanut Butter Brownie Swirl Cookies
Making peanut butter brownie swirl cookies is like creating edible art — a fun, hands-on process where you get to play with dough and make beautiful, tasty patterns.
STEP-BY-STEP INSTRUCTIONS:
Start by preheating your oven to 350°F (175°C) and lining your baking sheets with parchment paper.
Step 1:
Make the peanut butter dough by mixing peanut butter, granulated sugar, and one egg in a bowl until smooth. This dough is delightfully simple, with the peanut butter doing most of the heavy lifting for flavor.
Step 2:
For the brownie batter, cream together softened butter and brown sugar in another bowl. Beat in the egg and vanilla extract. In a separate small bowl, whisk together the flour, cocoa powder, baking powder, and salt, then slowly add the dry mix to the wet ingredients until just combined.
Step 3:
Now comes the fun part: take small spoonfuls of each dough and gently press them together, lightly swirling without overmixing. You want the two doughs to keep their character while beautifully marbling. Roll into balls and place on the baking sheet.
Step 4:
Bake for about 10–12 minutes, or until the edges are set but the centers still look slightly soft. Let them cool on the sheet for a few minutes before transferring to a wire rack. As they cool, they’ll set up perfectly, giving you that dreamy chewy texture.
HELPFUL TIPS:
- Don’t overmix the doughs when swirling — gentle folding creates the prettiest marbled effect.
- Use a cookie scoop for evenly sized cookies.
- Slightly underbake for ultra-soft, fudgy centers.
- For extra indulgence, sprinkle a few chocolate chips on top before baking.
