Traditional German Obst Kuchen - Fresh Fruit Flan (Sponge Cake) - cooking recipe

Ingredients

1/4 lb margarine or 1/4 lb butter, softened
2 eggs, separated
1/4 lb sugar (150 grams or 1/2 cup plus 3 tablespoons sugar)
1/4 lb flour (150 grams or 1/2 cup plus 3 tablespoons flour)
1 (1/4 ounce) packet dry yeast
1 teaspoon vanilla (or 1 tablespoon vanilla sugar)
1/2 cup milk (approximate)
2/3 cup prepared custard (optional)
2 -3 cups fresh fruit such as strawberries (or kiwis, apricots, cherries)
1/2 cup fruit jam mixed with a little water, to glaze (red currant, strawberry or apricot jam)
freshly whipped cream, to serve

Preparation

Preheat oven to 350 degrees F.
In large bowl, beat yolks. Add sugar, softened margarine and yeast. Mix well.
Add flour, then vanilla and mix well.
In separate bowl beat egg whites until stiff. Add egg whites to flour mixture - then gradually mix in enough milk to give a soft dropping consistency.
Grease German flan pan. Add dough to greased pan, spreading evenly with a spatula.
Bake at 350F degrees for about 20 minutes until tests done with a toothpick.
Remove from oven. Cool in pan on a rack for 15 minutes, then invert on a cake plate or other large plate.
Arrange fresh berries or other fresh or canned fruits (kiwi slices, pineapple, gooseberries, apricots, and cherries are nice) on top of the inverted sponge cake (note: you may add a thin custard layer prior to filling with fruit, if you wish). Spread your favorite fruit glaze over the top of the fruit (may use a clear glaze or use strawberry or red currant jelly, or apricot jam). Chill until serving time.
Serve with dollops of fresh whipped cream, and a cup of coffee. Enjoy!
