Line a 9x9" or 10x10" square baking pan with parchment paper, snipping the corners to fit, and spraying down with nonstick spray (a little underneath helps keep it from shifting while adding batter).
Stir together the cooled melted butter, sugars, eggs, red food coloring and vanilla in a bowl that does not stain.
Separately, mix the flour, cocoa, baking powder and salt then combine to make a smooth batter.
Fold in white chocolate chips and spread the batter into the parchment lined baking pan.
Bake in the preheated oven for 40 minutes or until the internal temperature of the brownies registers 180°F. on an instant read thermometer.
Cool brownies in pan completely.
Mix ingredients for frosting (not the sprinkles) until smooth and spread over the cooled brownies, then decorating the top with sprinkles.
Allow the brownies to set up and dry for about an hour or so before cutting 4x4 into 16 bars.
