I used frozen mixed berries and added 1 T more orange zest than the recipe called for - it was fantastic! Just sweet enough to feel like you're eating something good for you, moist and chewy. I'm going to make these on the weekends and take them to work for breakfast during the week...yum!!!
Whole-wheat flour and flaxseeds give these maple syrup-sweetened blueberry muffins a delicious, nutty flavor. Compared to a traditional version of the recipe, they have four times the dietary fiber and substitute healthful monounsaturated fat (canola oil) for saturated fat (butter).
