Classic Blueberry Buckle

The “High-Rise” Blueberry Buckle

This is the ultimate partner for a cup of black coffee. It’s less of a dessert and more of a “substantial morning cake.”

🍴 Ingredients

The Cake:

  • 2 cups All-purpose flour
  • ¾ cup Granulated sugar
  • 2 tsp Baking powder
  • ½ tsp Salt
  • ¼ cup (½ stick) Unsalted butter, softened
  • 1 Large egg
  • ½ cup Whole milk
  • 2 ½ cups Fresh blueberries (if using frozen, do not thaw!)

The Buckle Streusel:

  • ½ cup Granulated sugar
  • 1/3 cup All-purpose flour
  • ½ tsp Ground cinnamon
  • ¼ cup (½ stick) Cold butter, cubed

👩‍🍳 Instructions

1. The Sandy Streusel

  • In a small bowl, combine the sugar, flour, and cinnamon.
  • Cut in the cold butter using a pastry blender or two knives until the mixture looks like coarse crumbs. Keep this in the fridge until the very last second—cold streusel equals a crunchier buckle!

2. The Stiff Batter

  • Preheat your oven to 190°C (375°F). Grease an 8-inch or 9-inch square baking pan.
  • Cream the butter and sugar together. Add the egg and beat until pale.
  • Alternately add the flour/baking powder and the milk.
  • Note: This batter will be much thicker than a standard cake batter—almost like a soft cookie dough. This is necessary to support the “buckling” effect.

3. The Blueberries

  • Gently fold in the blueberries. Because the batter is thick, use a sturdy spatula to ensure they are distributed without crushing the fruit.

4. The Top-Heavy Layer

  • Spread the batter into the pan. Evenly sprinkle the chilled streusel over the top. It will look like a lot of topping, but as the cake “buckles,” much of it will fall into the cracks.

5. The Bake

  • Bake for 40 to 45 minutes. The top should be golden brown and a toothpick should come out clean.
  • The Cooling Rule: Let it sit for 15 minutes. This allows the fruit juices to re-absorb into the cake, making it moist rather than wet.

The “Cast Iron” Variation: For an extra-crispy bottom crust, bake this in a well-seasoned 9-inch cast iron skillet. The iron retains heat better than glass or tin, giving the “buckle” a caramelized, slightly salty edge that perfectly balances the sweet berries.
