Pre-heat oven to 190°C.
In a large bowl combine the oats, baking powder, salt, and cinnamon. Set aside.
In a medium bowl mash one banana with the back of your fork until you have a baby food-like consistency. Mix in egg whites, milk, jaggery and vanilla. Combine everything together and then pour wet ingredients into the dry ingredients and combine well.
Grease an 8x8 metal baking pan and line with one sliced banana. Pour the oat mixture over the bananas and then top with the other sliced banana and blueberries and then pop in the oven for 25 minutes or until golden brown and cooked through.
Cool and slice into four pieces. Enjoy!
