Frosting for Prune Cake and Some Tasty Pies

I realized I forgot the frosting for Thursday's Kentucky Prune Cake. Hard to believe there is a frosting for this one, and it has even more prunes! This is also under Abraham Lincoln's Birthday recipes.

Cream Cheese Frosting
1 3 oz. package cream cheese
6 cooked prunes, chopped
1 box powdered sugar
Prune juice or cream (Again - is this really interchangeable?)

Mix the cream cheese and prunes in a bowl.  Add the sugar and enough prune juice for spreading consistency and beat until smooth.  Spread on cake.

Yikes.
This sounds better:

Peanut Crunch Pie
1/3 c. crunchy peanut butter
3/4 c. confectioners' sugar
1 baked 9-in. pastry shell
1/3 c. flour
1/2 c. sugar
1/8 tsp. salt
1 tbsp. instant coffee
1 tall can evaporated milk (love the measurements here)
2 tbsp. butter
3 egg yolks, beaten
1/2 tsp. vanilla
Blend the peanut butter with confectioners' sugar until mixture resembles coarse meal.  Spread 2/3 of the mixture in bottom of the pastry shell.  Combine the flour, sugar, salt and coffee in a medium saucepan and stir in the milk.  Add the butter and cook over medium heat, stirring constantly; until thickened.  Remove from heat.  Stir 1/3 of the milk mixture into egg yolks gradually, then stir back into milk mixture in saucepan.  Bring to a boil, stirring constantly, and remove from heat.  Stir in the vanilla.  Pour over peanut butter mixture in pastry shell and sprinkle with remaining peanut butter mixture.  Cool, then chill.
