Preheat oven to 350F. Grease an 8x8 inch baking dish. Set aside.
In a large bowl, combine gluten-free certified oats, baking powder, cinnamon, nutmeg, ginger, and salt.
In a separate bowl, whisk together almond milk, applesauce, brown sugar and vanilla until combined.
Pour the wet ingredients into the oat mixture. Stir until combined.
Add the diced apples and dried cranberries. Stir until combined.
Pour into the prepared baking dish.
Bake in the oven at 350F for 40-50 minutes, or until the milk is mostly absorbed.
Serve warm with a drizzle of maple syrup.
