Best baked oatmeal

Just thought I'd share my favorite new breakfast. I've been eating it every day for breakfast for the las month and it's so delicious. So in a bowl mix together 2 cups quick oats, 1 tbsp cinnamon, 1 tsp baking powder, 1 cup frozen blueberries and 1 cup chopped walnuts. In another bowl whisk together 2 cups milk, 1 egg, 1/2 cup honey or pure maple syrup and 2 tsp vanilla extract. Pour over oat mixture and mix to combine. Spray a 9x13 pan with cooking spray and pour oat mixture into pan. Top with 1 chopped banana and bake at 350 degrees until set. Let cool and slice into 8. It's so delicious. Freezes well. It's 290 calories per serving. I usually eat it with 2 scrambled eggs on the side for a total of 440 calories and it keeps me full and satisfied until lunch. Full of protein, fiber and healthy fat.
Just thought I'd pass it along. Hope anyone who tries it loves it as much as me
