This recipe comes from noblepig.com via Pinterest. The thing I like about this brownie is the peanut butter really balances out the nutella and makes a really pleasing brownie.

• 1  cup butter, melted
• 2  cups granulated sugar
• 2 teaspoons vanilla extract
• 4 eggs, room temperature
• 1 cup (128 g) flour
• 3/4 cup cocoa
• 1/8 teaspoon salt
• 1/2 teaspoon baking powder
• 1/2 cup Nutella
• 1/2 cup peanut butter

Preheat oven to 350°. Grease bottom and sides of 9×13 pan; set aside. In a medium bowl combine all purpose flour, cocoa (sift this in to get rid of lumps), baking powder and salt. Set aside. Over low heat, melt butter and stir in sugar and vanilla extract until well combined. To the butter-sugar mixture whisk in the cocoa mixture until fully combined. In a microwave safe bowl add Nutella and peanut butter. Heat in the microwave in 20 second intervals until it reaches a runny consistency. Stir into the batter. Pour into prepared pan and bake for 30 minutes. Let brownies cool completely before cutting.
