Put 400 g flour, 50 g sugar and salt in a large bowl and mix. Press a depression in the middle. Warm 50 ml buttermilk lukewarm. Mix buttermilk, yeast, 1sp cinnamon, bitter almond flavour and 1 teaspoon sugar and pour into the bowl. Mix with flour from the rim and dust. Let rest for about 15 minutes
Add the egg, 250 ml buttermilk and 60 g butter in flakes and knead to a smooth dough. Cover and leave to rise again in a warm place for about 30 minutes
Melt 275 g butter. Mix 500 g flour, 1 pinch of cinnamon, 250 g sugar and salt in a bowl. Slowly stir in the butter and use the dough hooks of the hand mixer to make crumbles
Knead yeast dough again. Grease the fat pan of the oven (32 x 39 cm) and dust with flour. Roll out the dough and let it rise for about 15 minutes. Spread crumbles on top. Bake the cake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for approx. 30 minutes. Sprinkle the cake with 200 ml buttermilk halfway through the baking time
Take the cake out of the oven and let it cool down on a cake rack. Wash, clean and quarter the strawberries. Mix 1 tsp. sugar and strawberries. Dust the cake with icing sugar and serve lukewarm or cold with the strawberries. Whipped cream tastes good with it
Waiting time approx. 50 minutes
