For the Waffle Casserole with Peaches and Flaked Almonds, drain the peaches in a colander and slice them. Cut the waffles in half diagonally to make triangles.
Mix the eggs with the milk, whipped cream, custard powder and sugar. Preheat the oven to 175 °C top and bottom heat. Grease a large baking dish.
Layer the waffles and the peach slices in the baking dish. Pour the vanilla-egg whipped cream on top and bake in the preheated oven for 40-50 minutes. Cover with aluminum foil if necessary, if the surface is browning too much.
Toast the almond flakes in a frying pan without adding fat until golden brown. Remove the casserole from the oven. Serve the waffle casserole with peaches and flaked almonds dusted with powdered sugar.
