Buckles are classic Southern cakes made with berries. The name comes from the crumbled up-looking topping that sits atop the cake. This one is dense with blueberries and laced with lime for a beautiful flavor match. The moist texture is a nice contrast to the crunchy topping.

TOPPING
1/4 cup unsalted butter, softened
1/2 cup sugar
1 tablespoon grated lime peel
1/8 teaspoon salt
6 tablespoons all-purpose flour

CAKE
1/2 cup whole milk, room temperature
2 tablespoons lime juice
2 cups all-purpose flour
1 1/2 teaspoons baking powder
1/2 teaspoon salt
1/4 teaspoon baking soda
1/4 cup unsalted butter, softened
3/4 cup sugar

3 (6-oz.) containers fresh blueberries (about 3 1/2 cups)

1. Heat oven to 375°F. Spray 9-inch square baking pan with cooking spray.

2. Beat 1/4 cup butter in medium bowl at medium speed 30 seconds or until creamy. Beat in 1/2 cup sugar, lime peel and 1/8 teaspoon salt until blended. At low speed, beat in 6 tablespoons flour just until crumbly.

3. Whisk milk and lime juice in measuring cup. (Milk will thicken and curdle.) Whisk 2 cups flour, baking powder, 1/2 teaspoon salt and baking soda in medium bowl.

4. Beat 1/4 cup butter in another medium bowl at medium speed 30 seconds or until creamy. Beat in 3/4 cup sugar 1 minute or until fluffy. Beat in egg until well-blended. At low speed, beat in flour mixture in three parts alternately with milk mixture just until combined, beginning and ending with flour mixture. Gently fold in blueberries. Spread batter in pan; sprinkle with topping.
