Ingredients and Preparation
Before diving into the preparation, let’s take a look at the ingredients and what each one brings to the table:
Peanut Butter Filling:
- Peanut Butter: This is the creamy filling that gives these cookies their rich, nutty flavor. You can use either creamy or natural peanut butter. If you’re looking for a healthier alternative, natural peanut butter is a good option, though it might be a bit firmer to work with.
- Confectioners’ Sugar: This sugar gives the peanut butter filling its sweetness and helps it hold its shape, making it easier to form into balls.
Brownie Cookie Dough:
- Semi-Sweet Chocolate: This provides the main chocolate flavor in the cookie. Using high-quality baking chocolate will elevate the taste, creating a smoother, richer result than chocolate chips alone.
- Flour, Cocoa Powder, Baking Powder, Salt: These dry ingredients are essential for structure and balance, ensuring your cookies turn out chewy but not too dense.
- Butter and Sugars (Brown and Granulated): These add moisture, richness, and sweetness to the dough.
- Eggs and Vanilla Extract: These ingredients help bind the dough together and enhance the overall flavor profile.
- Espresso Powder: This is optional but highly recommended for deepening the chocolate flavor, making the cookies taste even more decadent.
Alternatives: If you’re looking for a nut-free alternative to peanut butter, you can use sunflower seed butter or Biscoff cookie butter. Additionally, you can experiment with bittersweet or unsweetened chocolate for a darker, more intense flavor.
Step-by-Step Instructions
Step 1: Begin by preparing the peanut butter filling. In a small bowl, mix together equal parts peanut butter and confectioners’ sugar. Stir until the mixture is smooth. Roll the mixture into teaspoon-sized balls and place them on a tray lined with parchment paper. Once all the peanut butter balls are rolled, freeze them for at least an hour.
Step 2: While the peanut butter filling chills, prepare the brownie cookie dough. Melt the semi-sweet chocolate in a double boiler or microwave. Let it cool slightly before adding it to the dough mixture. In a separate bowl, combine the flour, cocoa powder, espresso powder, baking powder, and salt. Set aside.
Step 3: In a large bowl, cream the butter and both sugars until smooth and creamy. Add the eggs and vanilla extract and beat until well combined. Gradually mix in the melted chocolate, followed by the dry ingredients. Once the dough is mixed, cover it and refrigerate for at least an hour to firm it up.
Step 4: Preheat the oven to 350°F (177°C) and line baking sheets with parchment paper. Scoop a tablespoon of cookie dough and press your thumb into the center. Place a peanut butter ball into the indentation and then cover it with more brownie dough, rolling the whole thing into a ball. Repeat this for the rest of the dough, making sure to space the cookie balls three inches apart on the baking sheet.
Step 5: Bake the cookies for 12-13 minutes, until the edges are set but the centers are still soft. Let the cookies cool on the baking sheet for 10 minutes before transferring them to a wire rack to cool completely.

Beginner Tips and Notes
- Chill the Dough: The cookie dough needs to be chilled before shaping to prevent it from being too sticky. This will make it much easier to work with and shape into balls around the peanut butter filling.
- Handling the Peanut Butter Filling: The peanut butter filling should be very cold before you handle it. If it starts to soften too quickly, return it to the freezer for a few more minutes.
- Don’t Overmix: When you mix the dough and the peanut butter filling, there’s no need for perfection. The marbled effect is part of the charm of these cookies, and it’s okay if they don’t look identical.
Serving Suggestions
These peanut butter-filled brownie cookies are rich enough to stand alone, but they pair well with a glass of milk or a scoop of vanilla ice cream for a truly indulgent treat. For a fun twist, you could also use these cookies as the base for ice cream sandwiches. Leftovers can be stored in an airtight container at room temperature for up to a week. If you want to save them for later, freeze the unbaked cookie dough balls and bake them fresh when you’re ready for a sweet treat.
Conclusion
These peanut butter-filled brownie cookies are a simple yet indulgent dessert that anyone can make, regardless of experience level. With their rich chocolate flavor and creamy peanut butter filling, they’re sure to become a favorite in your baking repertoire. I encourage you to give them a try and share your results in the comments – I’d love to hear how they turn out! Happy baking!
