Ingredients
- 1 box (18.3 oz) fudge brownie mix – I love using Ghirardelli, but any brand will do!
- 2 large eggs – For binding and richness.
- ½ cup unsalted butter, melted – Adds moisture and flavor.
- ½ cup creamy peanut butter – The star of the show!
- ½ cup granulated sugar – For extra sweetness and browning.
- ½ cup semi-sweet chocolate chips – Because more chocolate is always better.
- 1 teaspoon vanilla extract – Enhances the overall flavor.
- ¼ cup unsweetened cocoa powder – Deepens the chocolatey goodness.
- ¼ teaspoon salt – Balances the sweetness.
- Optional: peanut butter for drizzling – For an extra touch of peanut butter heaven!
How to Make It
- Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper – this makes cleanup a breeze!
- In a large bowl, combine brownie mix, melted butter, eggs, vanilla extract, cocoa powder, and salt. Stir until well combined. Don’t overmix; a few lumps are okay!
- Fold in the chocolate chips. I like to reserve a few for sprinkling on top later.
- Scoop teaspoon-sized portions of peanut butter onto a parchment-lined plate. Freeze for 15 minutes. This step is key for keeping the peanut butter centers firm.
- Scoop 2 tablespoons of dough, flatten slightly, and place a frozen peanut butter portion in the center. Wrap dough around the peanut butter, seal the edges, and roll into a ball. Place on your prepared baking sheet.
- Bake for 10-12 minutes, or until the edges are set and the tops are crackly. Keep a close eye on them; ovens vary!
- Cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely. Drizzle with warmed peanut butter, if desired.

Substitutions & Additions
Feel free to experiment! Try different types of peanut butter (crunchy!), add chopped nuts, or swap the semi-sweet chocolate chips for milk chocolate or dark chocolate.
Tips for Success
- Don’t overbake the cookies! Slightly underbaked cookies will be gooey and fudgy in the center.
- Make sure your peanut butter portions are truly frozen before adding them to the dough to prevent them from melting too quickly.
- For perfectly smooth peanut butter drizzle, microwave your peanut butter for short intervals, stirring until it’s smooth and pourable.
- These cookies are best enjoyed fresh, but you can store them in an airtight container at room temperature for up to 3 days (if they last that long!).
How to Store It
Store your cooled Peanut Butter Brownie Cookies in an airtight container at room temperature for up to 3 days. They are best enjoyed fresh, but they’ll still be delicious the next day!
FAQs
- Q: Can I use a different type of brownie mix? A: Absolutely! Any fudge brownie mix will work great.
