I bought some blueberries the other day and was looking for a new muffin recipe. I don't make blueberry muffins very often, and the last time I did they did not turn out so great. I found this great recipe here. These muffins turned out very moist with just the right touch of sweetness. I doubled the recipe and got 20 large muffins. One thing to note, the amounts for the crumb topping are too much. I had enough left to do at least two more batches so you might want to cut it in half.
