Buttermilk Blueberry Breakfast Cake

I found this recipe on Pinterest and was tasked with making something for Sunday Brunch, and with our CSA blueberries hanging out in the fridge this seemed like a good idea!

yield: 9 servings

ingredients
1/2C (1 stick) butter, room temperature
zest from 1 large lemon
7/8C (3/4C + 2 tbs) sugar
1 egg, room temperature
1 tsp vanilla
1 3/4C flour
2 tsp baking powder
1 tsp sea salt
1/2C buttermilk
2C fresh blueberries
1/4C flour (for coating blueberries)

2. Cream butter with lemon zest and 7/8 cup of the sugar until light and fluffy.
3. Add the egg and vanilla and beat until combined. 
4. Toss the blueberries with 1/4 cup of flour.
5. Whisk together the remaining flour, baking powder and salt. 
6. Add the flour mixture to the batter a little at a time, alternating with the buttermilk.
7. Fold in the blueberries.
8. Grease an 8" square baking pan (or something similar) with butter or coat with non-stick spray.
9. Spread batter into pan.
10. Sprinkle batter with remaining tablespoon of sugar.
