These were really good muffins. I normally like my muffins a bit sweeter than these turned out, but these were flavorful enough. The orange zest and crumb top really added a lot of flavor. I will definitely make these again but will probably increase the white sugar and brown sugar to 1/2 cup each (instead of 1/4 cup each)--just to satisfy my sweet tooth. But otherwise, these were perfect! Thanks cookiedog.
These muffins were delicious! :D The only substitute i made was low fat milk and I left out the cinnamon. This will be my go to blueberry muffin recipe.
