Buttercreme Cookie Icing

Found this recipe tonight, not sure how well it'd work for drying and not smudging/smashing. However I feel like it might be worth a try :D

Buttercream Frosting for Decorating Cookies:

Melt:
1 tablespoon butter

Add and beat until smooth:
3/4 cup confectioner’s sugar (sifted)
1 tablespoon milk
1/2 teaspoon vanilla
1/4 teaspoon lemon juice

Add food coloring if desired. Yields 1/3 cup

*When I make this icing I do not always add the lemon juice.  I scale this recipe up, starting with 10 Tablespoons butter, mixed with 10 Tablespoons milk.  To this I added 2 pounds of sifted powder sugar and two Tablespoons butter.  From there I made separate colors, and with each color I made a thick frosting for outlining and lettering, along with a thin icing for flooding the cookies.
