Coconut Pecan Frosting

1 c. sugar
½ c. margarine or butter
1 c. evaporated milk
1 tsp. vanilla
3 large egg yolks (if you get whites in this it looks really ugly)
1 1/3 c. flaked coconut
1 c. chopped pecans

1. Mix sugar, margarine, milk, and egg yolks in 2 quart saucepan. Cook over medium high heat for 12 to 15 minutes, stirring constantly, until thick.
2. Stir in coconut, pecans and vanilla.
3. Cool about 15 minutes, beating occasionally until spreadable.
