Reviews for Streusel-Topped Blueberry Muffins

"Like the previous reviewer, my family and I LOVED these muffins. I have had another recipe that I have used for years which was really good, but once I tried these, we all agreed that these were even better!! I too thought the batter was a little thick for muffins, but I went ahead without adding anything else and they turned out GREAT! They are so moist and tasty! I left off the glaze because I didn't think they needed it."
"This was one of the best muffins I've ever had. They disappeared so fast. I'm going to make another batch today. Sometimes I think people who write a poor review must have done something wrong to the recipe. Please give it a try and I think you'll be pleasantly surprised."
"This was awful!! What a waste! I normally go by reviews when making a recipe but there wasn't any and I was in a hurry to find a recipe for blueberry muffins. It is missing something, after I added the flour mixture I could hardly stir this it was like a cookie dough consistentcy and I hadn't even put in my blueberries yet, so to thin it out I tried adding some milk, rather than waste this I added my blueberries and the streusel topping and baked them, they looked okay but they were very bland tasting I threw them out. I just didn't want someone else to waste their time and ingredients making this. I will look for a different recipe. I was so disappointed!"
