Coffee's Great Sidekick

Although coffee is off limits for now, one can always enjoy a piece of the coffee's sidekick: blueberry crumble cake. Full of antioxidants, blueberries are delicious raw, but once baked, they are sweet and a little bit sour, which is perfect in a moist crumble cake. With an overgrowth of lemons in the backyard, I also added lemon zest to give it a citrus kick.
