Pound Cake Base
75g butter
75g caster sugar
1 tbsp vanilla sugar (heaped)
1 egg
150g all-purpose flour
50g cornstarch
1 tsp baking powder
2-4 tbsp milk
Beat butter until soft, add both types of sugar. Beat until pale and fluffy, the sugar should be dissolved. Add the egg and mix well. Add the dry ingredients and as much milk as needed (the dough should be rather on the stiff side). Spread into a prepared springform pan creating a little rim if desired).
Ricotta Filling
2 egg yolks
100g caster sugar
1 tbsp vanilla sugar, heaped
500g Ricotta (should be rather sour, do not use the ricotta for baked cheesecake)
2 egg whites
Beat the egg whites until stiff. In another bowl, beat the egg yolks and the sugar until pale and fluffy and the sugar is dissolved. Add ricotta and mix well. Gently fold in egg whites. Spread ricotta filling on top of vanilla dough.
Chocolate Crumble Topping
150g flour
30g cocoa
100g sugar
1 tbsp vanilla sugar, heaped
100g butter, cold, diced
Mix with your fingers until coarse crumbles form. Do not over mix (otherwise the butter will melt and mixture will get too soft to form proper crumbles). Sprinkle atop ricotta filling.
Fan-bake cake at 150 degrees Celsius (otherwise 170 degrees Celsius in a preheated oven) for about half an hour. If the ricotta filling is still wobbly, bake for another five minutes. Let cool down thoroughly before unmolding. Otherwise the cake might crack.
