These muffins were incredible! They were almost too moist. Several fell apart as I took them out of the tin and the blueberries made them extra moist at the bottom of the muffins. The recipe said it made approximately 20 muffins. Perhaps my muffin tins are small (although it's not a mini muffin pan) but this made around 30 muffins. The topping is crispy and very good. I will definitely make these again.
