Ingredients
- 1 cup unsalted butter
- 2 cups granulated sugar
- 4 large eggs
- 1 cup all-purpose flour
- 1 cup unsweetened cocoa powder
- 1/2 teaspoon salt
- 1 teaspoon vanilla extract
- 1 cup peanut butter
- 1/2 cup chocolate chips
- 1/2 cup peanut butter chips
Instructions
- Step 1: Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish or line it with parchment paper.
- Step 2: In a medium saucepan, melt the butter over low heat. Remove from heat and stir in the sugar, then beat in the eggs one at a time, mixing well after each addition.
- Step 3: Stir in the vanilla extract.
- Step 4: In a separate bowl, whisk together the flour, cocoa powder, and salt. Gradually add this dry mixture to the butter mixture, stirring until just combined.
- Step 5: Pour half of the brownie batter into the prepared baking dish and spread evenly.
- Step 6: In a microwave-safe bowl, soften the peanut butter for 20-30 seconds until easy to spread. Spread it evenly over the brownie batter layer.
- Step 7: Pour the remaining brownie batter over the peanut butter layer and spread it smoothly.
- Step 8: Sprinkle the chocolate chips and peanut butter chips evenly on top.
- Step 9: Bake for 30-35 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
- Step 10: Let the brownies cool completely in the pan before cutting into squares and serving.
Tips & Variations
- Use creamy peanut butter for a smoother layer or chunky for added texture.
- For extra richness, add a handful of chopped peanuts inside the batter or on top before baking.
- Swap out peanut butter chips for white chocolate chips to change up the flavor.
- Make sure not to overmix the batter to keep brownies fudgy rather than cakey.
Storage
Store the brownies in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for up to a week or freeze for up to 3 months. To reheat, warm in the microwave for 10-15 seconds to bring back their soft texture.

FAQs
Can I use natural peanut butter for this recipe?
Yes, natural peanut butter works, but it may be a bit runnier and oilier, so the peanut butter layer might be less thick. Stir well before using to keep it smooth.
How do I know when the brownies are done?
Insert a toothpick in the center and look for a few moist crumbs clinging to it. The brownies should not be too wet or raw, but slightly fudgy inside.
