Instructions
1
Preheat your oven to 350°F (175°C). Grease a 15x10-inch jellyroll pan and set aside.
2
In a medium saucepan over low heat, combine 1 cup of butter and 1/3 cup of cocoa. Stir frequently until the butter has melted and the mixture is smooth, then remove it from the heat and let it cool slightly.

Add the eggs and vanilla to the batter, mixing until completely combined and smooth.

Pour the brownie batter into the prepared jellyroll pan, spreading it out evenly. Bake for 20 minutes or until a wooden pick inserted into the center comes out clean.

While the brownies are baking, prepare the peanut butter topping. Remove the lid from the chunky peanut butter jar and microwave the peanut butter on medium power for 2 minutes, stirring once during cooking to achieve a creamy consistency.

Once the brownies are out of the oven, immediately spread the warm peanut butter over the surface. Let these sit to cool slightly for about 30 minutes.
