Granny’s Cocoa Cream Pie

Ingredients:

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

Directions: 

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
Or use the left over egg whites for a meringue topping!
