I tried making them yesterday, but by the time I had put all the ingredients together what I had in my bowl was totally liquid! (It's only after looking at the link again today, it does say you can add more sweetener and cocoa if the mixture is too runny)
I added 50g of almond flour and some baking powder and put the mixture into muffin cases. The result was yummy!
(I tried to add a pic, but it says the file is too large)
They sound fantastic! They’ve been saved in my low carb cooking recipe file and the ingredients added to my Tesco delivery! Managed to copy the pic from the recipe page for you
