Prepare brownie mix according to package directions for fudge-like brownies.

Spread batter into a greased and floured 9-inch round baking pan or you can use a 9-inch spring form pan.

Bake at 350 degrees for 30-35 minutes (or follow package directions); until the center springs back when lightly touched.

Cool for 10 minutes. Invert onto a serving plate; cool completely.

In a bowl, stir melted chocolate and butter until smooth. Spread over the brownie layer; refrigerate for 30 minutes.

Just before serving, top with whipped cream spreading from the center out, leaving about1-1/2 inches from edge without topping.

Decorate with sprinkles on top of the whipped cream.
