These are one of my favourite muffins that are worth the little bit of extra effort to make due to the need to grate the orange rind. Here is a tip to speed things up, every time you eat an orange grate the rind and store it in the freezer ready to add to your muffins.
I don’t use chocolate chips as I find them too sweet. I buy fair trade 70% chocolate block and chop it up. Of course you use whatever chocolate you prefer, milk or dark will work just fine
Perfect for the kids lunchbox.
Make a double batch, individually wrap them and store in a zip lock bag in the freezer. Defrost naturally otherwise the choc chips will become melted choc blobs
