Ingredients

FOR THE STREUSEL TOPPING

  • 6 tablespoons packed light brown sugar
  • 1.5 teaspoon ground cinnamon
  • ½ cup AP flour
  • ¼ teaspoon salt
  • 4 tablespoons unsalted butter cold, cut into ½-inch chunks

FOR THE CAKE

  • 1 stick ½ cup unsalted butter, softened
  • ¾ cup granulated sugar
  • 2 large eggs
  • 1 tablespoon pure vanilla extract
  • 2 cups AP flour spooned into measuring cup and leveled off
  • 2 teaspoons baking powder
  • ½ teaspoon salt
  • ½ cup milk
  • 2 cups frozen blueberries swap fresh if u must

Instructions

Make the Streusel Topping

  • Combine the brown sugar, flour, cinnamon, and salt in a small bowl. Use your fingers to break up any lumps of brown sugar. Add the butter and rub it in with your fingertips until the mixture is crumbly. If making ahead, transfer the streusel to an airtight container and refrigerate until ready to use.

Prepare the Batter

  • In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
  • In the bowl of an electric mixer, beat the butter and granulated sugar until creamy, about 2 minutes. Add the eggs one at a time, scraping down the sides of the bowl and beating well after each addition. Mix in the vanilla extract.
  • Gradually add the flour mixture, alternating with the milk, and beat on low speed until just combined. Gently fold in the berries with a spatula, being careful not to overmix. If making ahead, transfer the batter to an airtight container and refrigerate overnight.

Assemble the Buckle

  • Preheat the oven to 375°F and set an oven rack in the middle position. Grease a 9-inch square pan with butter or nonstick cooking spray.
  • Pour the prepared batter into the greased pan and spread evenly. Sprinkle the streusel topping evenly over the batter.

Bake the Buckle

  • Bake in the preheated oven for 40 to 45 minutes, or until the edges are golden brown and a cake tester or toothpick inserted into the center comes out clean.

Cool and Serve

  • Let the buckle cool in the pan on a rack for about 20 minutes. Serve directly from the pan and enjoy the cozy, festive flavors of Christmas morning!

Notes

Make-Ahead Option: To save time on a busy Christmas morning, you can prepare the batter and streusel topping the night before and keep them separate. For the batter, mix everything up through the step of folding in the berries and transfer it to an airtight container. For the streusel, mix the ingredients and store them in another airtight container. Keep both in the refrigerator overnight. In the morning, simply grease the pan, pour in the batter and blueberries, top it with the topping, and bake!
