You will need:
Spread mixture evenly in prepared pan. Bake at 350 for 25-30 minutes or until set. Let cool.
Step three? five? who's counting?: In small saucepan over low heat, melt 2 oz. semi-sweet chocolate and 1 oz. unsweetened chocolate, stirring constantly. Unless you like scalded chocolate. Remove from heat.
In large bowl, beat 2 eggs until frothy. Gradually add sugar-water mixture and beat on highest speed for 5 minutes (or stir really fast like I did) or until thick and lemon colored. Gradually add butter a small piece at a time, beating well after each addition.
Add melted chocolate to sugar-water-egg mixture and beat until smooth.
