Drain the cherries well on a sieve. Whisk eggs, vanilla sugar and sugar with the whisk of the hand mixer until creamy. Add buttermilk and orange baking and stir in.
Mix flour, baking powder and pudding powder, sieve onto the buttermilk-sugar mass and stir in. Fold chopped nuts and cherries into the dough, place on a greased pan of the oven (32 x 39 cm) lined with baking paper, smooth it down.
Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for approx. 30 minutes. In the meantime, roast the nut flakes in a pan without fat. Take the cake out of the oven, sprinkle evenly with the cream and let it cool down.
Before serving, dust with icing sugar and sprinkle with the nut flakes.
