Ingredients
  

Buckle Batter
  • 1.5 cups all-purpose flour
  • 0.5 teaspoon baking powder
  • 0.25 teaspoon baking soda
  • 0.25 teaspoon salt
  • 0.5 cup unsalted butter, softened Ensure at room temperature
  • 0.75 cup granulated sugar
  • 2 large eggs, room temperature
  • 1 teaspoon pure vanilla extract
  • 1 tablespoon fresh lemon zest
  • 0.75 cup buttermilk Can substitute with plain yogurt
  • 1.5 cups fresh blueberries Do not thaw if using frozen
Crumb Topping
  • 0.5 cup all-purpose flour
  • 0.33 cup granulated sugar
  • 2 tablespoons cold unsalted butter, cut into small pieces
  • 1 tablespoon fresh lemon zest
  • 1 tablespoon fresh lemon juice
  • 1 pinch cinnamon Optional

Method
 

Preparation
  1. Preheat your oven to 350°F (175°C). Grease a 9-inch square baking pan.
  2. In a medium bowl, whisk together 1½ cups of flour, baking powder, baking soda, and salt. Set this aside.
  3. In a large mixing bowl, cream together the softened butter and ¾ cup of granulated sugar until light and fluffy.
  4. Beat in the eggs, vanilla extract, and 1 tablespoon of fresh lemon zest until combined.
  5. Gradually mix in the flour mixture, alternating with the buttermilk. Begin and end with the flour mixture, mixing until just combined.
  6. Gently fold in the blueberries. Pour the batter into the prepared baking pan.
Crumb Topping and Baking
  1. For the crumb topping, mix ½ cup of flour, ⅓ cup of sugar, lemon zest, lemon juice, and cinnamon in a separate bowl.
  2. Cut in the cold butter until crumbly.
  3. Sprinkle the crumb topping evenly over the batter.
  4. Bake for 40 to 45 minutes or until a toothpick inserted into the center comes out clean.
  5. Allow to cool for at least 10 minutes before serving.

Notes

Ensure that the butter is softened to room temperature for easy mixing. Avoid overmixing your batter to keep the buckle light and fluffy. For extra flavor, try adding a touch of almond extract along with the vanilla. Use fresh blueberries for the best taste; if using frozen, do not thaw them.
