Healthy blueberry pancakes - gluten, sugar free

Ok, so my mind is blown.  Last night I posted on Facebook to see if anyone had any healthy pancake recipes, and I was inundated with a flurry of wonderful-sounding suggestions from my healthy, foodie friends.  One struck a chord, which is gluten-free, sugar-free pancakes made from banana, egg and cinnamon.  Surely that can't taste nice?!  Then I tried it, and, in the words of 50 Shades, oh my:

You will need:

• 3 egg whites
• 1 whole egg
• 1 banana
• cinnamon
• blueberries
• cooking spray
• hand mixer
• non-stick frying pan

Method:

1. Separate three eggs into whites and yolks.  Keep the whites, stores the yolks for another time.
2. Add one whole egg.
3. Chop a banana into the mix.
4. Add a sprinkling of cinnamon (be as generous as your like).
5. Using the hand mixer, blend the lot together until there are no lumps and it's frothy.
6. Add whole blueberries to the mix.
7. In a non-stick frying pan, heat up some cooking spray and spoon a dollop into the pan.
8. Let it bubble and, once the blueberries start to burst, you know it's time to flip.
9. If the pancake doesn't flip easily, then it isn't quite ready - leave it for 30 seconds more.
10. Flip it over, and then leave for only 30 seconds max to brown on the other side.
11. Slide on a pre-warmed dish.
12. Cover your pancakes in a cloth so they keep warm whilst you cook the rest.
13. Serve with fresh blueberries (it is plenty sweet enough so no need for sugar) and/or crème fraiche.
