This is an authentic blueberry cake recipe from the blueberry capital of the world: Maine.
The difference between this and most other blueberry cakes, is that it is light and airy. It doesn’t contain the denseness one would expect from a cake, and that’s its charm. Sprinkled sugar baked on top creates a thin, delicate crispy crust.
The recipe comes from Kim MacIsaac of Peaks Island, just a 15-minute ferry ride from Portland. Kim is a historian and has written several books on the history of that small island. She also owns the Peaks Island Tour Company

I first ate a piece of this cake at a wedding rehearsal dinner for my son Sean, and his wife, Emmy. Kim’s daughter, Courtney, catered the dinner via her company The Maine Lobsterbake Company. When I ordered this cake for dessert, she told me it was her mother’s recipe.
A few weeks later, I stumbled across the recipe in the Peaks Island Directory. And about a week after that, I made it in the Rootsliving kitchen.
The recipe is pretty easy. It just requires a few bowls: one to whip up the egg whites and another to cream the shortening.

You also have to do a lot of folding. You fold in the egg whites and then you fold in the blueberries, which have been dusted with a light coating of flour.
Don’t stir the batter too much. You want to keep the consistency of the batter, light and airy.
