Chop the apple into thin pieces. Place the apple, mulberries, and sugar in a heat-resistant container. Cover with plastic wrap and microwave on high for 8 minutes.
While the filling is cooking, make the topping.
Add the flour, oatmeal, wheat bran, sugar, and cinnamon to a bowl and mix. Pour in the vegetable oil and stir. Add the egg and milk and stir some more.
Remove the filling from the microwave and stir in 1 tablespoon of flour and mix. Add another 1/2 tablespoon of flour and mix.
Top the filling with spoonfuls of the topping batter. Bake in an oven preheated to 200°C for 15 minutes and it's done.
Serve with ice cream while still piping hot.
Story Behind this Recipe
Spreading out pie crust is too much work (I'm just lazy...) so I make this really easy cobbler. It's tastes just as delicious as pie and is a standard dessert for my family.
Adjust the amount of flour depending on the amount of juice released from the fruit. If you don't have wheat bran, it's not a problem. Just leave it out. You can also adjust the amount of vegetable oil or butter. This also tastes good if made with canned peaches, just apples, mulberries + blueberries, etc.
