Buttermilk-Blueberry Breakfast Cake

Thomas & Sallie were in town this past weekend and Saturday morning I made a yummy new breakfast bread! It was a hit & the boys loved it too! 

what you need...½ cup unsalted butter, room temperature
2 tsp. lemon zest or more — zest from 1 large lemon
7/8 cup* + 1 tablespoon sugar**
1 egg, room temperature
1 tsp. vanilla
2 cups flour (set aside 1/4 cup of this to toss with the blueberries)
2 tsp. baking powder
1 tsp. kosher salt
2 cups fresh blueberries
½ cup reduced fat buttermilk

* 7/8 cup = 3/4 cup + 2 tablespoons
** This 1 tablespoon is for sprinkling on top

what to do...

Preheat the oven to 350ºF. Cream butter with lemon zest and 7/8 cup of the sugar until light and fluffy. Add the egg and vanilla and beat until combined. Meanwhile, toss the blueberries with ¼ cup of flour, then whisk together the remaining flour, baking powder and salt.Add the flour mixture to the batter a little at a time, alternating with the buttermilk. Fold in the blueberries. 

Grease a 9-inch square baking pan (or something similar) with butter or coat with non-stick spray. Spread batter into pan. Sprinkle batter with remaining tablespoon of sugar. Bake for 45 minutes. Check with a toothpick for doneness. If necessary, return pan to oven for a couple of more minutes. (Note: Baking for as long as 10 minutes more might be necessary.) Let cool at least 15 minutes before serving.
