Step‑by‑Step Instructions for Fudgy Peanut Butter Brownie Cookies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (180°C). While the oven warms up, line two baking sheets with parchment paper to prevent the cookies from sticking. This simple preparation step is essential for achieving those beautiful edges and ensuring an easy cleanup afterward.
Step 2: Melt the Chocolate
In a microwave-safe bowl, chop the bittersweet chocolate and melt it in the microwave, stirring every 15 seconds until smooth. Once fully melted, mix in your neutral oil until well combined, and then allow the mixture to cool slightly. This rich chocolate base is key to the depth of flavor in your fudgy peanut butter brownie cookies.
Step 3: Beat the Eggs and Sugar
In a stand mixer fitted with a whisk attachment, combine the large eggs, an extra egg yolk, and granulated sugar. Beat on high speed for 2-3 minutes until the mixture is light, airy, and pale in color. This step creates the perfect structure for your cookies and a lovely shine on their tops, enhancing their decadent appeal.
Step 4: Combine Chocolate and Vanilla
Once your egg mixture is fluffy, pour in the slightly cooled melted chocolate along with the vanilla extract. Mix on medium speed until thoroughly combined. This indulgent blend will give your fudgy peanut butter brownie cookies a luscious flavor that’s hard to resist.
Step 5: Add Dry Ingredients
Gently fold in the all-purpose flour, Dutch-processed cocoa powder, and salt until just incorporated. Be careful not to overmix, as this could lead to tough cookies. The dough will be thick and fudgy, indicating that you’re on your way to creating the best peanut butter brownie cookies!
Step 6: Incorporate Chocolate Chips
Using a spatula, fold in the chocolate chips, ensuring they’re evenly distributed throughout the cookie dough. These chocolatey bursts will complement the rich peanut butter center, making each bite of your fudgy peanut butter brownie cookies deliciously indulgent.
Step 7: Shape the Cookies
With a cookie scoop, form balls of dough and place them on the prepared baking sheets, spacing them about 2 inches apart. Create an indent in the center of each ball, fill it with creamy peanut butter, and then cover with a small amount of dough to seal it. This step is crucial for achieving that gooey peanut butter surprise in every cookie.
Step 8: Bake the Cookies
Place the baking sheets in the preheated oven and bake for 10-12 minutes. Keep an eye on them; you’ll know they’re done when the edges are set, but the centers appear slightly soft. This balance of textures is what makes these fudgy peanut butter brownie cookies truly delightful.
Step 9: Cool Before Serving
Allow the cookies to cool on the baking sheets for 5-10 minutes before gently transferring them to a wire rack. This helps them firm up while retaining their chewy centers. Once cooled completely, you can savor these rich, marbled treats that perfectly blend chocolate and peanut butter bliss.

Fudgy Peanut Butter Brownie Cookies Recipe FAQs
What type of peanut butter should I use for these cookies?
I recommend using creamy peanut butter for a rich, nutty flavor and a gooey center. Natural brands with no added sugar can work, but avoid oily ones that may affect the texture of the cookies. If you prefer a chunkier texture, feel free to use crunchy peanut butter!
How should I store my peanut butter brownie cookies?
For optimal freshness, store your cookies in an airtight container at room temperature for up to 4-5 days. Make sure they’re completely cooled before storing to prevent sogginess. If you’re planning to keep them longer, freezing is a great option!
Can I freeze the cookie dough?
Absolutely! To freeze the dough, scoop out balls and place them on a baking sheet lined with parchment paper. Freeze until solid, then transfer the cookie dough balls to a freezer-safe bag. They can be stored for up to 3 months. When you’re ready to bake, you can bake them directly from frozen—just add a couple of extra minutes to the baking time!
What should I do if my cookie dough is too sticky to handle?
If your dough seems sticky, don’t worry! Chill it in the refrigerator for about 15-30 minutes. This will firm it up, making it easier to scoop and shape without any mess. Alternatively, you can lightly oil your hands to help roll the dough balls.
Are there any dietary considerations for these cookies?
Yes, if you’re preparing these cookies for someone with allergies, make sure to use allergy-friendly substitutes, like gluten-free flour or vegan eggs. It’s important to check the chocolate and peanut butter brands too for hidden allergens. Always inform anyone consuming them if they contain common allergens like nuts or gluten.
