Buckeye Brownies

Ingredients

• 1 package fudge brownie mix (13x9-inch pan size)
• 1/2 cup butter plus 6 tablespoons butter, divided
• 1 cup creamy peanut butter
• 2 cups confectioners' sugar
• 6 ounces semisweet or dark chocolate chips

Instructions

1. 1

   Bake the brownies: Combine the brownie mix with the eggs and oil. Bake the brownies in a greased 13x9-inch pan according to the brownie package directions. Let the brownies cool completely before proceeding. Editor's Tip: Line your baking pan with parchment and grease it lightly with cooking spray or butter for easy brownie removal.

2. 2

   Make the peanut butter layer: In a large microwaveable bowl, microwave 1/2 cup butter and the peanut butter on high for 30 to 60 seconds, until the butter has melted. Add the confectioners' sugar and stir until smooth. Spread the peanut butter mixture over the cooled brownies. Editor's Tip: An offset spatula—one of our Test Kitchen's go-to gadgets—makes it easy to spread the peanut butter and chocolate layers evenly.

3. 3

   Make the chocolate layer: In another large microwave-safe bowl, microwave the chocolate chips and remaining 6 tablespoons butter on high for 30 seconds and then stir. Continue microwaving in 30-second increments, stirring between each time, until completely melted. Spread the chocolate mixture over the peanut butter layer. Editor's Tip: If you prefer not to use a microwave, melt the chocolate and butter in a double boiler.

4. 4

   Cool and slice: Let the peanut butter and chocolate layers cool completely. Editor's Tip: Refrigerate the pan of brownies for at least an hour to help set the peanut butter and chocolate layers. Then, cut the brownies into squares.
