Best Blueberry Buckle

Ingredients

• 2 cups all-purpose flour
• 2 teaspoons baking powder
• 1/2 teaspoon salt
• 1/4 cup unsalted butter
• 3/4 cup white sugar
• 1 large egg
• 1/2 cup milk
• 2 1/2 cups fresh blueberries
• 1/2 cup white sugar
• 1/3 cup all-purpose flour
• 1/2 teaspoon ground cinnamon
• 1/4 cup unsalted butter, softened

Directions

Preheat oven to 350 degrees F (175 degrees C). Butter and flour a springform pan.

Sift 2 cups flour, baking powder, and salt into a bowl.

Beat 1/4 cup butter, 3/4 cup sugar, and egg with an electric mixer in a large bowl until smooth. Gradually add milk and beat until fluffy; stir in flour mixture, making a stiff batter. Gently fold in blueberries and spread batter into prepared springform pan.

Mix 1/2 cup sugar, 1/3 cup flour, cinnamon, and 1/4 cup butter in a bowl until blended and crumbly in texture. Sprinkle on top of batter, then lightly press topping into batter using fingertips.

Bake in preheated oven until golden and a toothpick inserted in the middle comes out with moist crumbs, about 40 minutes.
