Fresh berries are not always available when you want them so I made these beauties with canned blueberries. I made two types with the same batter, one with the blueberries mixed with the batter and the other with the berries in the centre only.
I also made a cinnamon flavoured crumb coating and sprinkled it on top of the muffins before they went into the oven. This not only gives a crunch to the soft gooey filling but also lends a warm cinnamon-y flavour!
