Tips for Perfect Mint Chocolate Bars

A few helpful tips will give you the best results.

Cool the brownie base completely

Warm brownies will melt the frosting layer.

Use a sharp knife

Wipe the knife between cuts for clean layers.

Chill before slicing

This helps the chocolate topping stay smooth and neat.
