For an even richer flavor, consider using a high-quality dark chocolate brownie mix. If you don't have toffee bits, chopped nuts or chocolate shavings can be used as a substitute. To ensure the frosting spreads smoothly, make sure the brownies are completely cooled before applying it. For a boozier brownie, brush the cooled brownies with an additional tablespoon of Irish cream liqueur before frosting.

Jul 19, 2024Make sure you let the brownies cool completely, otherwise the frosting will melt! Learned that the hard way.
