Description

This effortless breakfast cake features a tender, moist buttermilk crumb packed with juicy blueberries and finished with a crunchy, golden sugar crust. It is a perfect make-ahead treat that brings a touch of bakery-style luxury to any morning.


Ingredients

  • 1 cup unsalted butter, softened
  • 1 tablespoon fresh lemon zest
  • 1 cup granulated sugar, plus 1 tablespoon for topping
  • 1 large egg, room temperature
  • 1 teaspoon pure vanilla extract
  • 2 cups all-purpose flour, divided
  • 2 teaspoons baking powder
  • 1 teaspoon kosher salt
  • 1/2 cup buttermilk, room temperature
  • 2 cups fresh blueberries


Instructions

  1. Preheat and prepare. Preheat your oven to 350°F and grease a square baking pan, lining the bottom and sides with parchment paper for easy removal.
  2. Cream butter mixture. Beat the softened butter, lemon zest, and one cup of sugar in a mixer for three to four minutes until light and fluffy.
  3. Add egg and vanilla. Incorporate the egg and vanilla extract, beating until the mixture is smooth and fully emulsified.
  4. Prepare dry ingredients. Toss blueberries with 1/4 cup of the flour in a small bowl, then whisk the remaining flour, baking powder, and salt in a separate container.
  5. Combine the batter. Alternately stir the dry ingredients and buttermilk into the butter mixture until just combined, then gently fold in the floured blueberries.
  6. Fill and top. Spread the thick batter into the prepared pan and sprinkle the reserved tablespoon of sugar evenly over the surface.
  7. Bake the cake. Bake for 35 to 45 minutes until a toothpick inserted into the center comes out clean, then cool on a wire rack before serving.

Notes

  • Ensure all dairy and egg components are at room temperature to prevent the butter from curdling during mixing.
  • Measure flour by weight rather than volume to maintain the cake’s delicate, tender texture.
  • Tossing blueberries in flour before adding them to the batter is essential to stop the fruit from sinking.
  • You can prepare the batter the night before and refrigerate it, allowing it to sit at room temperature for 30 minutes before baking.
