Why I Love This Recipe
One of my fave frosting recipes
Ingredients You'll Need
12 ounces Scharffen Berger 70% Cacao Bittersweet Chocolate
12 ounces (1-1/2 cups) or 1 can evaporated milk
6 tablespoons unsalted butter
2 tablespoons Tia Maria, coffee liquor
Directions
Melt the chocolate in the top of a double boiler or in a bowl over simmering but not boiling water.
Put the evaporated milk, butter and 2 tablespoons of Tia Maria in the bowl of a food processor.
Add the chocolate and process until the frosting is thick and creamy.
Use immediately to frost the cake.
*If the frosting is not thick enough to frost the cake immediately, refrigerate it for half an hour or let stand at room temperature for one hour until it is sufficiently thick.
