If you’re looking for a delicious, seasonal, berry cake recipe to add to your morning-treat repertoire, this buttermilk blueberry breakfast cake is perfect!


  • 1/2 cup unsalted butter, room temperature
  • 2 tsp. lemon zest or more – zest from one large lemon
  • 7/8 cup* + 1 tablespoon sugar**
  • 1 egg, room temperature
  • 1 teaspoon vanilla
  • 2 cups flour
  • 2 teaspoons baking powder
  • 1 teaspoon kosher salt
  • 2 cups fresh blueberries
  • 1/2 cup buttermilk

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


  1. Preheat oven to 350 degrees F. Cream butter with lemon zest and the 7/8 cup of sugar until light and fluffy.
  2. Add the egg and vanilla and beat until combined. Meanwhile, toss the blueberries with 1/4 cup of flour in a small bowl, then whisk together the remaining flour (1 3/4 cup), baking powder, and salt in a separate bowl.
  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, like I used) with butter or non-stick spray. Spread batter into pan. Sprinkle batter with the remaining tablespoon of sugar. Bake for 35 minutes. Check with a toothpick for doneness. If necessary, return pan to oven for a couple more minutes. (Note: Baking for as long as 10 more minutes might me necessary. I had to leave mine in for 12 more minutes.) Let cool for at least 15 minutes before serving.
