Crumble the biscuits in a tray and pour a packet of butter over them. Chop the apples and peaches into cubes, sprinkle with vanilla sugar and cinnamon, pour these over the biscuits, distributing them evenly.
Put raisins and raw nuts on top (store-bought mix) and stir the mixture for the topping with a mixer. Once you get a nice cake mixture, pour it on top.
I baked in a preheated 302°F (150 °C) oven because mine is really powerful. Bake to a dry toothpick. Sprinkle with powdered sugar at the end.
