Blitzer Cake

This is an old favourite from Irene Nickerson's collection of recipes. I found it and baked it last week for my daughter Beverley's birthday. The method is lacking detail!

First step
1/2 c white sugar
1/2 c butter
3 egg yolks (well beaten)
4 tbsp. milk
1 c flour
1 tsp baking powder

Spread in two round layer tins

Second step

4 egg whites beaten stiff
Add 1 c white sugar and beat well
Spread this layer over batter

Sprinkle with 1 c chopped nuts (I use Almonds)
Bake 20 minutes at 350

Third Step:

Cool on rack and put together with filling

Filling:
1 egg yolk
2 tbsp white sugar
1 c milk
1 tsp corn starch
vanilla
Cook until thick
