Add the dry ingredients (oat flour, ground flax, baking powder, baking soda) to a large mixing bowl. Mix together well.
In a separate mixing bowl, whisk together the wet ingredients (mashed banana, maple syrup, chia eggs, coconut oil).
Add the wet ingredients to the dry. Mix together really well, then fold in the grated carrot.
Distribute the batter evenly between muffin cases, arranging them on a baking tray. Bake for 20-22 minutes, until a toothpick comes out clean but they are still soft on the inside.
Notes
To make one chia egg, mix together 1 tbsp chia seeds with 2.5 tbsp water (so for two, you need 2 tbsp chia seeds and 5 tbsp water).
