ingredients
For the Brownie Base:
- 1 cup (226g) unsalted butter
- 2 cups (340g) semisweet chocolate chips
- 1 1/2 cups (300g) granulated sugar
- 4 large eggs
- 2 teaspoons vanilla extract
- 1 cup (127g) all-purpose flour
- 1/2 cup (43g) unsweetened cocoa powder
- 1/2 teaspoon salt
For the Peanut Butter Filling:
- 1 cup (250g) creamy peanut butter
- 1/2 cup (60g) powdered sugar
- 1/4 teaspoon salt
Directions
Prepare the Peanut Butter Filling:
- In a medium bowl, mix together the creamy peanut butter, powdered sugar, and salt until completely combined.
- Line a small baking sheet with parchment paper.
- Drop tablespoon-sized scoops of the peanut butter mixture onto the parchment paper, creating about 12-16 mounds.
- Place the baking sheet in the freezer for at least 30 minutes until the peanut butter scoops are firm.
Make the Brownie Batter:
- Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving some overhang for easy removal.
- In a large microwave-safe bowl, combine the butter and chocolate chips. Microwave in 30-second intervals, stirring between each, until completely melted and smooth.
- Whisk in the granulated sugar until well combined, then let the mixture cool slightly.
- Add the eggs one at a time, whisking well after each addition. Stir in the vanilla extract.
- In a separate bowl, whisk together the flour, cocoa powder, and salt.
- Gradually fold the dry ingredients into the chocolate mixture until just combined. Be careful not to overmix.
Assemble and Bake:
- Pour half of the brownie batter into the prepared baking pan, spreading it evenly.
- Remove the frozen peanut butter scoops from the freezer and arrange them evenly across the brownie batter, pressing them in slightly.
- Carefully spread the remaining brownie batter over the peanut butter scoops, covering them completely.
- Bake for 30-35 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs (but not wet batter).
- Allow the brownies to cool completely in the pan before lifting them out using the parchment paper overhang.
- Cut into squares and serve.
Frequently Asked Questions
1. Can I use natural peanut butter for this recipe?
While you can use natural peanut butter, traditional creamy peanut butter (like Jif or Skippy) works best for the filling as it holds its shape better when frozen. If using natural peanut butter, you may need to add a bit more powdered sugar to achieve the right consistency.
2. How do I know when the brownies are done baking?
Insert a toothpick into the center of the brownies. They’re done when the toothpick comes out with a few moist crumbs attached but not wet batter. Be careful not to overbake, as this will result in dry brownies instead of fudgy ones.
3. Can I make these brownies ahead of time?
Absolutely! These brownies actually taste even better the next day as the flavors have time to meld. Store them in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
4. Can I freeze these peanut butter stuffed brownies?
Yes, these brownies freeze wonderfully. Cut them into squares, wrap individually in plastic wrap, then store in a freezer-safe container for up to 3 months. Thaw at room temperature before serving.
5. Can I add other mix-ins to the brownie batter?
Certainly! Try adding 1/2 cup of chopped nuts, extra chocolate chips, or even peanut butter chips to the brownie batter for added texture and flavor. Just fold them in gently before assembling the brownies.

Tips
