Drain the peaches well. Cream soft fat, sugar, salt and flavour. Stir in eggs bit by bit. Mix flour and baking powder and stir in alternately with the egg liqueur
Smooth the dough in a greased fat pan (approx. 35 x 40 cm). Spread the peaches evenly on the dough with the convexity downwards and press in a little. Sprinkle with nuts and bake in a preheated oven (electric cooker: 200 °C / convection oven: 175 °C / gas: level 3) for 25-30 minutes. Let it cool down and dust with icing sugar
