Warm milk in a pot lukewarm. Melt 100 g butter at low heat and let it cool down lukewarm. Crumble yeast into the lukewarm milk and stir with a whisk until the yeast has dissolved. Put flour, salt, 100 g sugar, vanillin sugar, egg and melted butter into a mixing bowl, pour yeast milk over it, knead to a smooth dough with the dough hooks of the hand mixer. Cover and leave to rise in a warm place for about 30 minutes. Then knead again with floured hands on the work surface. Put it on a greased grease pan of the oven and roll it out evenly.
Leave in a warm place for another 30 minutes. Cut 125 g cold butter into small cubes and press them evenly into the yeast cake. Sprinkle with flaked almonds and 75 g sugar. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for about 25 minutes. Take out of the oven and let cool down a little. Tastes best fresh. Tastes best with whipped cream and cinnamon
