Buttermilk Blueberry Breakfast Cake

I made this yesterday for our breakfast this morning. Wow, it was so good, and so very moist!!! I was looking for something to use up some buttermilk I had in the fridge, and found this breakfast cake I had pinned on Pinterest awhile back. It has just the tiniest hint of lemon, and mixed with the blueberries and the moistness of the cake from the buttermilk....SUPER YUMMY!!!!! It is very springy tasting to me..and how perfect that we had it for breakfast on this 1st day of Spring!! I think it would be very good for an Easter brunch or Mother's Day brunch!!

Serves 6-8

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
2 tsp. baking powder
1 tsp. kosher salt
2 cups fresh blueberries ( I used frozen blueberries, and it was just fine!)
½ cup buttermilk

* 7/8 cup = 3/4 cup + 2 tablespoons
** This 1 tablespoon is for sprinkling on top (I added some cinnamon to the 1 Tbsp of sugar that goes on top of the cake..it was really good!!!)

1. Preheat the oven to 350ºF. Cream butter with lemon zest and 7/8 cup of the sugar until light and fluffy.

2. 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.

3. Add the flour mixture to the batter a little at a time, alternating with the buttermilk. Fold in the blueberries.

4. 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 (or cinnamon and sugar mix). Bake for 35 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. Mine only needed 5 more minutes) Let cool at least 15 minutes before serving.
