Here's a recipe I'm trying right after I type this.
It looks so good! I'll come back and update this post with my and
my family's reaction.
1 cup granulated sugar
1/4 cup cocoa
1/4 cup butter
1/4 cup milk
1 teaspoon vanilla
Mix together. Bring to a boil and boil for 1 minute. Add vanilla. Cool partially, then beat with a mixer for 3 minutes or until spreadable consistency.
Update: Yum! You have to let it cool, mix it to death, then let it cool again. It is more of a creamy icing than a thick frosting.
