Ingredients

For the Cake:

  • 6 tablespoons unsalted butter, at room temperature
  • 3/4 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon pure vanilla extract
  • 1/2 teaspoon grated lemon zest
  • 2/3 cup sour cream
  • 1 1/4 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1/4 teaspoon baking soda
  • 1/2 teaspoon salt
  • 11/4 cup fresh blueberries

For the Crumb Topping

  • 1 cup all-purpose flour
  • 1/2 cup granulated sugar
  • 1/2 teaspoon lemon zest
  • 1/2 cup unsalted butter, at room temperature

Instructions

  • Preheat the oven to 350 degrees Fahrenheit.. Butter and flour a 9-inch baking pan.

To Make The Crumb Topping

  • Combine the flour, sugar, lemon zest, and butter in a bowl. blend well with a pastry blender, a fork, or your fingers to form crumbs. Set aside

To Make The Cake

  • In the bowl of an electric mixer fitted with the paddle attachment, cream the butter and sugar for about 4 - 5 minutes or until light and fluffy.
  • With the speed on low, add the eggs one at a time and mix to combine. Add the vanilla. lemon zest and sour cream and mix to combine.
  • In a separate bowl, sift together the flour, baking powder, baking soda and salt. With the mixer on low speed, add the flour mixture to the batter until just combined. With a spatula, gently fold in the blueberries until combined.
  • Pour the batter into the prepared pan and spread it evenly.  Sprinkle the topping crumbs evenly over the batter.
  • Bake for 40 to 50 minutes, or until a cake tester or toothpick comes out clean. Cool completely and serve.

Notes

  • The cake batter is thick and will prevent the blueberries from sinking to the bottom of the cake. There is no need to coat the blueberries with flour. 
  • Make sure your eggs are at room temperature. Room temperature eggs mixed with the butter-sugar mixture create a nice emulsion and produce baked cakes with an even crumb. 
  • Add the eggs one by one, and mix just until each egg is nicely incorporated and the mixture looks smooth. Don't over mix!
