In a mixing bowl, add the oats, brown sugar, nuts, flax, cinnamon, baking powder, ginger, and salt. Stir to combine. Spread evenly over the fruit.
In a separate bowl whisk the milk, egg, vanilla and maple extracts.
Pour this evenly over the oats.
Drizzle the melted butter over top and sprinkle with coarse sugar.
Bake for 45-50 minutes, until top is browned and lightly puffed up.
Let cool for 5-10 minutes before serving.
Notes
Storing leftovers: Store leftovers in the fridge and reheat in the microwave.Variations: Almost any type of fruit or nuts will work here, and you can change the milk as well. Bananas (layer with the fruit) and blueberries are a good combo.
