Step 4: Shape & Swirl
- Scoop 1 tablespoon of peanut butter dough and 1 tablespoon of brownie dough, placing them side by side on a parchment-lined baking sheet.
- Use a toothpick or skewer to gently swirl the two doughs together in a circular motion. Avoid overmixing—you want distinct swirls, not blended dough.
Step 5: Bake to Perfection
- Preheat oven to 350°F (175°C).
- Bake for 9-11 minutes, until the edges are set but the centers are still slightly soft.
- Remove from the oven and let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack.

Baking Tips for the Best Swirl Cookies
Achieving the perfect Peanut Butter Brownie Swirl Cookies is all about technique! Follow these expert tips to get chewy, fudgy, and beautifully marbled cookies every time.
1. Use Room Temperature Ingredients
- Butter and eggs should be at room temperature before mixing. This ensures smooth incorporation and prevents the dough from being too stiff or greasy.
- If you forgot to take your egg out in advance, submerge it in warm water for 5 minutes.
2. Chill the Dough for Defined Swirls
- Chilling the dough for at least 30 minutes prevents the cookies from spreading too much and helps maintain distinct peanut butter and brownie layers.
- If the dough gets too hard, let it sit at room temperature for 5 minutes before scooping.
3. Don’t Over-Swirl the Dough
- Use a toothpick or skewer to gently swirl the two doughs together. Over-mixing will blend the flavors instead of creating the marbled effect.
- A few light swirls are all you need for a perfect pattern!
For another beautifully swirled treat, try Caramel Cheesecake Cookies—they have a rich caramel swirl that complements their soft, buttery texture.
4. Bake Until the Edges Are Set
- Bake at 350°F (175°C) for 9-11 minutes.
- The cookies should have set edges but slightly soft centers—they will continue baking as they cool.
5. Store for Maximum Freshness
- Keep cookies in an airtight container at room temperature for up to 5 days.
- For longer storage, freeze baked cookies for up to 3 months—just reheat in the microwave for a warm, gooey treat!
