Following a recipe given to me by T.'s sister I baked a wonderful cake yesterday. The children as well as T. and myself have all been eating happily. T. was especially happy when he found out that the cake worked really well together with the raspberry sorbet he had made. Thank you so much for the recipe, S.!

UPDATE:
Ingredients: 125 g melted butter, 400 g sugar, 400 g flour, 4 teaspoons cinnamon, 2 teaspoons sodium bicarbonate, 1/2 litre milk. Whisk the melted butter and sugar and add milk. Then add the rest of the ingredients. Pour the batter into a pan (size 23x33 cm) and bake in the oven (200°C) for about 30 min. Let it cool slightly. Then whisk 50 g of melted butter, 250 g powdered sugar, 2 teaspoons vanilla powder, 1 tablespoon cacao powder together with 4 tablespoons of hot coffee. Pour it on top of the cake and let it set. Done!
