How to make
Beat the butter with the egg yolk and milk, add the flour and knead a dough.
Lay it out in a suitable tray and make a 1 tall border. Poke it with a fork in several places and sprinkle with 2 tbsp sugar.
Cut the washed pears into thin slices and arrange them in concentric circles on top of the dough. Sprinkle with cinnamon. Bake the cake in a preheated 390°F (200 °C) oven for about 20 min.
Take it out, sprinkle with the remaining 2 tbsp sugar and bake another 20-25 min. at 360°F (180 °C). You can garnish the cooled cake with whipped cream.
