I just blended it all together and poured it into muffin tins. I baked for about 15-20 minutes on 180C until fork came out clean.
The icing I'm going to attempt tomorrow I saw online on a paleo site.
You take coconut cream in the fridge overnight then remove the cream bit in a bowl and whip until creamy. Yeah icing without the sugar.
If you wanted to have protein with your muffin then chug down a protein shake with it or replace some of the flour with protein powder. I've done this before it will make it a bit dry but you could throw in an extra egg or a couple egg whites or a bit more banana.
