Ingredients

Scale
  • 2 cups (240g) all-purpose flour, sifted
  • 1 cup (200g) granulated sugar
  • 2 teaspoons baking powder
  • 1/4 teaspoon salt
  • 1/2 cup (115g) unsalted butter, softened
  • 2 large eggs, room temperature
  • 1/2 cup (120ml) whole milk (or almond milk for dairy-free)
  • 2 teaspoons lemon zest, freshly grated
  • 2 tablespoons fresh lemon juice
  • 1 1/2 cups (225g) fresh blueberries
  • For the streusel topping:
  • 3/4 cup (90g) all-purpose flour
  • 1/3 cup (70g) light brown sugar, packed
  • 1/2 teaspoon ground cinnamon (optional)
  • 6 tablespoons (85g) cold unsalted butter, cut into small cubes

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9-inch square or 8-inch round baking pan or line with parchment paper.
  2. Make the streusel topping by combining 3/4 cup flour, 1/3 cup brown sugar, and 1/2 teaspoon cinnamon in a medium bowl. Add cold butter cubes and cut into mixture with a pastry cutter or forks until coarse crumbs form. Chill in fridge.
  3. In a large bowl, sift together 2 cups flour, 1 cup sugar, baking powder, and salt.
  4. In a separate bowl, beat 1/2 cup softened butter until smooth. Add eggs one at a time, beating well after each. Mix in lemon zest and lemon juice.
  5. Gradually add dry ingredients to the butter-egg mixture alternately with milk, starting and ending with flour mixture. Mix until just combined.
  6. Fold in blueberries gently with a rubber spatula, being careful not to crush them.
  7. Pour batter into prepared pan and smooth the top. Evenly sprinkle chilled streusel topping over batter.
  8. Bake for 45-50 minutes until a toothpick inserted in the center comes out with a few moist crumbs and the streusel is golden and crunchy. If streusel browns too fast, tent with foil halfway through baking.
  9. Cool in pan on a wire rack for about 20 minutes before slicing.

Notes

Keep butter cold for the streusel topping to ensure a crumbly texture. Do not overmix the batter to keep the buckle tender. Fold blueberries gently to avoid crushing. Use fresh lemon zest and juice for best flavor. Tent with foil if streusel browns too quickly. Frozen blueberries can be used if tossed in flour first.
