Chocolate Broiler Cake - cooking recipe

Ingredients

cake
1 (4 ounce) package sweet German cooking chocolate, divided in two
1/2 cup butter
1/2 cup sugar
1 teaspoon vanilla
7 egg yolks
2/3 cup flour
3 tablespoons cornstarch
7 egg whites
1/4 cup sugar
icing
3 tablespoons butter
2 cups sifted powdered sugar
boiling water

Preparation

grease and line bottom of 8x8 inch pan with wax paper.
melt half the chocolate and set aside.
beat 1/2 cup sugar for 30 sec, add vanilla and beat till fluffy.
add egg yolks one at a time, beating well.
mix flour and cornstarch together, then stir into beaten mixture.
divide batter in half.
add melted chocolate to ONE half, stirring well.
wash beaters VERY WELL.
beat egg white in separate bowl until soft peaks form.
gradually add 1/4 cup sugar, beating till stiff peaks form.
divide egg whites in half and fold the halves, one at a time (chocolate second), into divided batters with a spatula. Batter may appear curdled at
this point but that is normal.
spread scant 1/2 cup of chocolate batter evenly in prepared pan.
Place pan approx 5 inches from flame in broiler and cook 1-2 minutes.
Spread scant 1/2 cup plain batter on top of cooked chocolate cake, bake under broiler flame 1-2 minutes.
repeat steps with remaining batter, trying to keep all additions 5 inches from flame. If this cannot be done simply reduce cook time by a few seconds for each additional layer.
When done you should have around 10 layers.
cool in pan 10 minutes, loosen side with butter knife, invert onto wire rack, remove wax paper and cool.
ICING DIRECTIONS.
melt together remaining chocolate and 3 tbsp butter.
Stir in powdered sugar until crumbly.
pour in enough boiling water to make drizzling consistency (about 1/4 cup).
cut cake and drizzle each piece with chocolate.
