The information can be varied depending on your taste. Some like more fruit, some like a little more cream and less yoghurt, just give it a try!
Whip the cream until stiff and stir in the yoghurt until it becomes uniform. Cut the peaches into small pieces and place them in a bowl, casserole dish or something similar with the drained raspberries. Spread the cream and yogurt mixture over it and sprinkle with enough brown sugar.
