Here is a great old hard to find recipe

Granny’s Cocoa Cream Pie

It’s simple and tasty. This really was a simple desert often used during the 30’s and 40’s.

½ c. cocoa

¼ cup cornstarch/or arrowroot powder (or ½ c. all purpose flour)

3 egg yolks

1 ½ c. sugar

¼ tsp. salt

2 c. milk

1 tsp. vanilla

Mix cocoa, cornstarch, beaten egg yolks; sugar and salt, then add milk gradually, while stirring in a pot over med-high heat. Cook until thick, beating it smooth. Cream pies take some time to thicken, so stir... and stir (10-15 min). Using a heavy bottom pan really helps. Just keep it up until it thickens. Pour into a pre-baked pie shell. Put in the fridge to chill, add whipped cream if you like :0 Or use the left over egg whites for a meringue topping!
