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
- 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.
- 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.
- Add egg and vanilla. Incorporate the egg and vanilla extract, beating until the mixture is smooth and fully emulsified.
- 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.
- Combine the batter. Alternately stir the dry ingredients and buttermilk into the butter mixture until just combined, then gently fold in the floured blueberries.
- Fill and top. Spread the thick batter into the prepared pan and sprinkle the reserved tablespoon of sugar evenly over the surface.
- 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.
