Add the banana to a small mixing bowl mash with a fork until it's no longer.
Stir in the grated carrot, egg, oats and cinnamon and mix until combined.
Warm a large non stick skillet on a medium high heat. Melt a little butter or oil if needed for your pan. Once the pan is hot ladle about 1/4 cup of the batter onto the pan. Use the back of a spoon to spread out the pancakes into the right shape and let cook for 2-3 minutes. Once the edges are cooked and golden and little bubbles form over the top of the uncooked side carefully flip over the pancakes. Cook for another 2-3 minutes on the other side under full cooked and then remove from the heat.
