Blueberry Buttermilk Bake

Inspired by a recipe from Pinterest, again! This made a fantastic group brunch dish... I'm sure you could use other berries (would probably be good with raspberries)

Ingredients:

1 cup unsalted butter, room temperature

Zest from 1 large lemon
2 c. white sugar
2 eggs, room temperature
2 tsp. vanilla
4 cups flour
4 tsp. baking powder
1 tsp. kosher salt
4 cups fresh blueberries
1 cup buttermilk

Directions:

1. Preheat the oven to 350ºF. Set aside 2 Tablespoons of the sugar.  Cream butter with lemon zest and remaining sugar until light and fluffy.

2. Add the eggs and vanilla and beat until combined. Meanwhile, toss the blueberries with 1/2 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 9x13" pan with butter or coat with non-stick spray. Spread batter into pan. Sprinkle batter with  reserved sugar. Bake for 35-50 minutes. Check with a toothpick for doneness. Let cool at least 15 minutes before serving.
