I made this Blueberry Coffee Cake for breakfast the other day and everyone thought it tasted like a giant blueberry muffin. There are no other flavors going on here, so it has a pretty basic taste. I had a slight problem getting mine out of the pan, some of the blueberries were abandoned on the bottom of the pan and it made me think that this could be served as a Blueberry Upside Down Cake because the blueberries sink to the bottom quite a bit.
All in all, it was a good little breakfast treat. Very simple and basic.
