Lemon Blueberry Cake

This one-bowl loaf cake is exceptionally easy to make. Since the batter calls for oil instead of butter, there's no need for a creaming step—just quickly beat together the ingredients until smooth, then fold in the blueberries. Thanks to plenty of sour cream and minimal leavener, the cake bakes up rich and tender, ready for the final touch of a puckery lemon glaze topped with plenty of fresh lemon zest. To enjoy it as a breakfast cake, just skip the glaze.
