- In a separate bowl, cream together the softened butter, granulated sugar, and brown sugar until fluffy.
- Mix in the egg, vanilla extract, and peanut butter until smooth.
- Add the flour, baking soda, and salt, and mix until a soft dough forms.
Step 3: Swirl the Doughs Together
- Take 1 tablespoon of brownie dough and 1 tablespoon of peanut butter dough and gently press them together.

Step 5: Serve & Enjoy!

Tips & Tricks for the Best Swirl Cookies
✅ Chill the Dough – This helps the flavors develop and prevents the cookies from spreading too much.
✅ Don’t Overmix the Swirl – You want distinct swirls, so gently press the two doughs together instead of fully mixing.
✅ Use Creamy Peanut Butter – Avoid natural peanut butter, as it can make the dough too oily.
✅ Underbake Slightly – The cookies will continue setting as they cool, giving them that soft and chewy texture.
✅ Make Them Extra Fancy – Sprinkle with flaky sea salt or mini chocolate chips before baking!
