In a casserole, mix strawberries with raspberries and maple syrup. Bring to a boil and stir from time to time. Lower heat and simmer for 4 minutes until obtaining a compote.
In a small bowl, dilute cornstarch in water. Add to the casserole and bring again to a boil while continuously stirring. Remove from heat and set aside.
Preheat oven to 375°F (190°C).
Mix flour with oat flakes, brown sugar, and baking soda in a bowl. Add butter and work the preparation with your hands until you obtain a grainy dough; pieces of fat must be about the size of a green pea.
Butter a mold 33 cm x 23 cm (13 inches x 9 inches). Divide half the dough at the bottom of the mold, then press to make everything uniform. Pour the fruit preparation and uniformize with a spatula. Cover the remaining with dough.
Oven bake for 30 minutes, until the top is roasted. Remove from oven and cool completely before cutting into bars.
