This NO BAKE recipe comes from a 1959 Disney's Sleeping Beauty comic book that my mother saved from her childhood!
Prep: 10 minutes Chill: 1 hour
3 oz unsweetened Baking Chocolate
1/4 c. Butter
3 c. Powdered Sugar
1 tsp. Vanilla
Melt unsweetened baking chocolate and butter in small sauce pan over medium heat.
Mix in half of the powdered sugar. Beat in the egg (remember it was the 50s, you can substitute egg for 1/4 c. vegetable oil) Add remaining sugar and vanilla. Press into 8x8 baking pan lined with wax paper (make sure to line it or it will be impossible to remove!) Chill for 1 hour, or until firm!
