Cut the peaches into bite sized pieces and toss them with the blueberries, 3 tbsp of brown sugar, the corn starch and a pinch of salt.
Preheat the oven to 350 ℉ (180 ℃) with convection (fan).
Mix the rest of the brown sugar, flour, oats and vanilla sugar in a large bowl. Cut the butter into small cubes and mix it into the dry ingredients. Rub it with your fingers until you form crumbs.
Put the fruit in a pie form and cover with the oat crumbs. Sprinkle chopped almonds on top and put into the oven. Bake for 25-30 minutes. Done!
