Preheat oven to 176C (350F) /gas mark 3-4 and in a bowl add almond flour, flax seed, bananas and baking powder. Mix all ingredients well in a bowl until you get a thick consistency. Spread the batter evenly inside the cupcake liners into a baking tray and bake for 20-25 minutes or until it starts to become a slightly darker brown on the top. Let it completely cool before cutting and serving. Decorate and cream once cooled.
