Preparation & Instructions:
- 7 Tbsp. unsalted butter, melted
- 2 large eggs
Preheat oven to 350℉. Grease and flour, or spray an 8-inch square pan. Place brownie mix in a bowl of an electric mixer. Add melted butter and eggs. Mix until well incorporated. Spread into prepared pan and smooth top. Place chocolate chips in a saucepan. Melt over low heat while stirring. (You can also place the chips in a microwave-safe bowl and heat on high, stirring every 15 seconds until the chips have completely melted.) Swirl melted chocolate onto the top of the brownie. Bake 26-30 minutes. Cool on a rack before cutting.
