These delightful little muffins are very quick and easy to bake, and they burst with flavors. The blackberries give them a nice tartness, and their taste also goes very well with the hazelnuts. You can either use fresh or frozen blackberries. If you plan to use frozen berries, you don't have to thaw them beforehand.
You can also substitute with other berries or nuts, so change them up and you have a new muffin all year round.
