- Grease a deep casserole dish or lasagna pan.
- Spread the berries evenly across the bottom of the dish.
- In a large mixing bowl, combine oats, coconut, nuts/seeds, cinnamon, nutmeg, baking powder and salt.
- Pour the oat mixture evenly over the berries.
- In the same mixing bowl used before, beat the egg and then mix in the milk, vanilla, oil or butter, and maple syrup.
- Pour the milk egg mixture over the oat mixture, but do not stir.
- Let sit in the fridge overnight.
- Ensure the oven rack is in the middle of the oven.
- Preheat oven to 350° F.
- Bake for 60 min or until the top is slightly firm and golden.
- Serve with a scoop of yogurt.
Note: If you're serving babies, you can mix 1/4 cup of peanut butter or sunflower seed butter into the egg/milk mixture, instead of adding nuts or seeds to the oat mixture.
