Banana Cream Pie: Make the basic filling and cool. Slice 3 to 4 bananas into the bottom of the prepared pie shell. Pour the cooled basic filling (or chocolate filling) on top. Coconut Cream Pie: Stir 1 cup flaked coconut into basic filling just before pouring into pie shell. Sprinkle toasted coconut on top of the whipped cream for a beautiful and tasty presentation. Butterscotch Cream Pie: Substitute 3/4 cup firmly packed brown sugar instead of white sugar in the basic filling recipe, and increase the butter to 3 tablespoons. Cook in the same manner as the basic filling. Peanut Butter Chocolate Cream Pie: Make the basic filling and add 1/4 cup creamy peanut butter and 3/4 cup good quality chopped semi-sweet chocolate to the hot filling in the pan. Stir until the chocolate is completely melted.
