Pre-heat oven to 350℉. Spray an 8 inch square baking dish with non-stick spray and set aside.
In a large bowl mix the oats, baking powder, cinnamon and salt. Set aside.
In a medium bowl, mash banana then add milk, honey, egg and vanilla until combined.
Add wet ingredients to the dry ingredients and mix well. Once all ingredients are fully combined, fold in the blueberries.
Pour into the prepared baking dish and smooth out the top to make it even.
Bake at 350° for 30-40 minutes until the top is a light golden brown. Then enjoy!
I served mine with a dollop of plain Greek yogurt. When serving from cold, microwave for 10 seconds. Slightly warm is how we enjoy it best!
