You mix together: 4 tablespoons self-rising flour, 3 tablespoons cocoa, 1 cup sugar (Note: I would add about half a cup first and taste mix to see if it is sweet enough. You can always add more sugar when you are cooking the pie mix until you like the taste.)
Separate 3 eggs. Mix the egg yolks with 1 ½ cups of milk and tsp of vanilla.
Add to the dry ingredients, add a dash of salt. Cook in saucepan on low/med heat until thick, stirring constantly. If it doesn't thicken up, you can add a little extra flour. Add 2 tsp of butter and stir until melted.
Pour into baked pie crust. Then make meringue using the three egg whites and 2 tablespoons sugar. Use mixer on high to beat egg whites until fluffy, add sugar, and continue mixing until peaks are formed.
Spread meringue on top of pie and bake at 350 until lightly browned. Cool, cut and serve.
