Peanut Butter Brownie Swirl Cookies Ingredients
For the Peanut Butter Dough
• Creamy Peanut Butter – Offers an irresistibly nutty richness; use almond butter if you have allergies.
• Butter (softened) – Brings moisture and richness; substitute with dairy-free butter for a dairy-free version.
• Brown Sugar – Adds sweetness and chewiness; light brown sugar works best, but coconut sugar is a great alternative.
• Egg – Binds everything beautifully; for a vegan option, try a flax egg or another egg substitute.
• Vanilla Extract – Gives a delightful depth of flavor; it’s best left in but can be omitted if needed.
• All-Purpose Flour – Provides structure; swap with a gluten-free flour blend if you prefer.
• Baking Soda – Helps the cookies rise for a lighter texture; can be skipped if using self-rising flour.
• Salt – Balances the sweetness; essential for enhancing flavor, but you can reduce it if your butter is salted.
For the Brownie Dough
• Melted Butter – Adds indulgent fudginess; for dairy-free options, use dairy-free butter.
• White Sugar – Contributes to chewiness and sweetness; coconut sugar can make this refined sugar-free.
• Cocoa Powder – Delivers a deep chocolate flavor; be sure it’s unsweetened for the best results.

Step‑by‑Step Instructions for Peanut Butter Brownie Swirl Cookies
Step 1: Make Peanut Butter Dough
Begin by preparing the peanut butter dough. In a mixing bowl, beat together ½ cup of creamy peanut butter, ¼ cup of softened butter, and ½ cup of brown sugar until the mixture is light and fluffy, approximately 2-3 minutes. Next, mix in one egg and one teaspoon of vanilla extract until well combined. In a separate bowl, whisk together 1 cup of all-purpose flour, ½ teaspoon of baking soda, and a pinch of salt. Gradually combine the dry ingredients with the wet mixture until a soft dough forms.
Step 2: Make Brownie Dough
Now, move on to the brownie dough. In another mixing bowl, whisk together ¼ cup of melted butter with ½ cup of white sugar until smooth and creamy. Add in ¼ cup of cocoa powder, mix well, and then incorporate one egg and one teaspoon of vanilla extract. Slowly fold in ½ cup of flour, ½ teaspoon of baking soda, a pinch of salt, and ½ cup of chocolate chips, stirring until fully combined. The brownie dough should be thick and fudgy.
Step 3: Chill Doughs
Once both doughs are prepared, it’s time to chill them for optimal consistency. Cover each dough in plastic wrap and place them in the refrigerator for about 30 minutes. This chilling step not only firms up the doughs, making them easier to handle but also helps the flavors meld together, ultimately enhancing the deliciousness of your Peanut Butter Brownie Swirl Cookies.
Step 4: Scoop and Swirl
After chilling, preheat your oven to 350°F (175°C) and prepare your baking sheet by lining it with parchment paper. Using a cookie scoop, portion out the peanut butter dough and brownie dough, placing them side by side on the baking sheet. Aim for the same dough amount for each scoop to create balance. With a toothpick, gently swirl the two doughs together to create a marbled effect, being careful not to overmix.
Step 5: Bake
Now it’s time to bake your delicious cookies! Place the baking sheet in the preheated oven and bake for 9-11 minutes. Keep an eye on the cookies; they are ready when the tops appear lightly crackly and the edges are just set while the centers remain soft. This baking time ensures a delightful chewiness, perfect for your Peanut Butter Brownie Swirl Cookies.
Step 6: Cool
Once baked, remove the cookies from the oven and allow them to cool on the baking sheet for about 5-10 minutes. This cooling period lets the cookies set properly, making them easier to transfer. After cooling slightly, gently lift the cookies onto a wire rack to cool completely. Your irresistible Peanut Butter Brownie Swirl Cookies are now ready to enjoy!
