To a large mixing bowl, add the eggs, almond milk, maple syrup, melted butter, and vanilla extract. Whisk all of the wet ingredients together until well combined.
Next, add the gluten free oats, baking powder, ground cinnamon, and salt to the mixing bowl and stir until well combined.
Lastly fold the fresh blueberries into the oat batter.
Transfer the blueberry oatmeal batter to a greased 11×7 baking dish.
Bake at 350 degrees for 25-30 minutes until the oatmeal is just almost set.
