Double Choc Chip Protein Muffins

I was inspired to bake some muffins this week when I was came across some really cute pink silicone muffin cases whilst shopping for bits for the flat in Ikea.
I've already done a skinny blueberry muffin (recipe here) so the next obvious choice was chocolate!
Unlike a regular muffin this version is kept lower in fat by using Greek yoghurt in place of oil or butter. For this batch I actually used a protein yoghurt by Arla called "Skyr" which is part quark, part yoghurt (you can buy it in most supermarkets) to take the protein content up even more. These muffins contain only 85 calories & 9g protein each.
These muffins are sweetened with Stevia to keep the carbs lower but if you prefer a more sugary hit then you could add a little honey or Choc Shot to the recipe too. Likewise, if you have a few more fats to play around with then adding a tablespoon of coconut oil to the mix will make them much squidgier & more indulgent.
