I call this "a study in blue"

One of my favorite cookbooks is from the Black Dog Tavern on Martha's Vineyard.  In this landlocked heat, oh! wouldn't it be loverly this morning to sit on a cool harborside porch drinking hot coffee and eating some of their Blueberry Butter Cake?  And we're not even quite at the "dog days of summer" yet.  I've been so fortunate to find wonderful blueberries this year I just had to make up a couple of these.

I've got a dozen banana-blueberry muffins made up for the Market today, too.

Oh, yeah.  There's also the died-and-gone-to-heaven pineapple upside-down cake.
