In a bowl mash banana and combine with protein powder until mixed thoroughly.
In a separate bowl combine the buckwheat flour and baking soda. Add the coconut yoghurt and mix until you form a thick sticky batter. Once you have reached the desired consistency add the banana/ protein mix and stir until combined.
Spoon the batter onto the pan to form each pancake and repeat until the batter has been used. Use coconut oil to grease pan as required.
