Ingredients

Cooking spray
1 large overripe banana, mashed sub: 1 cup unsweetened applesauce
3/4 cup milk DF option: Use plain non-dairy milk.
2 large eggs
1 teaspoon vanilla extract
2 tablespoons avocado oil or melted coconut oil
1/3 cup pure maple syrup
3 cups old-fashioned oats GF Option: Use gluten-free oats.
1/4 cup ground flaxseed sub: more oats
2 teaspoons baking powder
1/2 teaspoon cinnamon
1/4 teaspoon salt
1 cup fresh or frozen blueberries do not thaw the frozen ones!
Optional for serving: milk, sliced almonds or chopped pecans, blueberries, sliced bananas, more maple syrup

(Optional) Vanilla Drizzle:

1 tablespoon milk DF option: Use plain non-dairy milk.
1/2 teaspoon pure vanilla extract
Pinch of salt
1/2 cup powdered sugar

Instructions

Preheat the oven to 350°F. Spray an 8x8-inch casserole dish with cooking spray.
In a medium mixing bowl, add the banana and mashed really well with a fork. Add the milk, eggs, vanilla, oil, and maple syrup and whisk together with the banana until combined. (Another option is that you can throw all these ingredients in the blender and blend until smooth. This will avoid any banana chunks.)
In a large mixing bowl, stir together the oats, flax, baking powder, cinnamon, and salt. Pour the wet ingredients into the dry ingredients and stir until well combined. Stir in the blueberries. Pour the batter into the greased casserole dish.
Bake for about 35-40 minutes (if using frozen blueberries or a glass pan, it may take 5-10 minutes longer), or until firm around the edges and the middle is set but not too firm.

Make the (Optional) Vanilla Glaze:

Let oatmeal cool while you make the Vanilla Glaze. In a small bowl, stir together the milk, vanilla, salt, and powdered sugar. Once the baked oatmeal has cooled a little bit, use the spoon to drizzle it all over the top.
Serve the baked oatmeal warm in a bowl with a little milk on top. You can also top with sliced bananas, more blueberries, sliced almonds or chopped pecans, if desired.

Notes

You can skip the Vanilla Drizzle and add a little more maple syrup at the end if you need it.
For Gluten-Free, be sure to buy oats that say gluten-free.
For Dairy-Free, use non-dairy milk.
