These muffins don't last long! You'll love the crumby streusel topping!
Brilliant recipe! I have never made muffins before and this one worked out really well. Will definitely be trying it again soon. - 10 Apr 2016
Good receipe. The topping is great. - 13 Jul 2010
The muffin itself is great, not too sweet, which is as a muffin should be. Fluffy, tender and moist. It is the streusel, however, that I didn't like. Even though I used chilled butter as called for, it wasn't until I added two tablespoons more of both brown sugar and flour that I got a true streusel consistency. As written, the streusel is too heavy with butter. Had I used the streusel as is, while I'm sure it would have been acceptable, it would more than likely have somewhat melted into the muffin rather than being the crumb-like streusel topping I was after. Once I "fixed" it (at least to MY liking) all was fine, and I had a perfect blueberry streusel muffin. - 31 Aug 2009 (Review from Allrecipes US | Canada)
