Pizzeria Limone Brownies

For the Lemon Cream Frosting:

In a large mixing bowl, mix the butter, powdered sugar, lemon juice, and rind. Add water or milk 1 T. at a time until you get a nice soft consistency. Beat for about 5 minutes.

Spread evenly over cooled brownies. Let sit until the frosting develops a crust.

Melt together for 1 minute in a microwave-safe bowl. Remove and stir. Melt for an additional 30 seconds if needed. Stir until smooth. Pour over the frosting and smooth lightly with an offset spatula.

Refrigerate until chocolate is set. When you want to cut the brownies, let them come to room temperature so that the chocolate doesn't break while you cut them. Run a sharp, long knife under hot water and quickly wipe it dry with a paper towel. Make a lengthwise cut, then repeat the heating and drying of the knife for every cut. This will give you beautiful sharp edges.
Store tightly covered.
