Instructions

• Prepare the Betty Crocker Fudge Brownie Mix and bake in the pan called for on the package, following the package directions exactly; when baking is complete, remove the pan from the oven.
• Evenly sprinkle 2 cups marshmallows over the hot brownies. Turn the oven off, then return the pan to the hot, turned-off oven and close the door. Leave in the oven 2–3 minutes, until the marshmallows puff and soften, then remove the pan.
• While the marshmallows are puffing (or immediately after removing the pan), make the frosting: in a medium saucepan combine 6 tablespoons half and half, 6 tablespoons butter, and 1 1/2 cups white sugar.
• Heat the mixture over medium heat, stirring frequently to prevent scorching, until it comes to a boil. Once boiling, continue to boil for 1 minute while stirring.
• Remove the saucepan from the heat and immediately add 1/2 cup chocolate chips. Stir until the chocolate chips are fully melted and the frosting is smooth.
• While the frosting is still warm, spread it evenly over the marshmallow-topped brownies. Allow the frosting to set before cutting and serving.
