Classic Blueberry Buckle
Ingredients
Streusel topping
-
½ cup all-purpose flour
-
½ cup sugar
-
½ tsp ground cinnamon
-
¼ tsp salt
-
4 tbsp unsalted butter, melted
Cake
-
2 cups all-purpose flour
-
2 tsp baking powder
-
½ tsp salt
-
½ cup unsalted butter, softened
-
¾ cup sugar
-
1 large egg
-
½ cup milk
-
1 tsp vanilla extract
-
2 cups fresh blueberries (or frozen, not thawed)
Instructions
-
Heat oven to 375°F (190°C).
Grease an 8- or 9-inch square pan. -
Make the streusel:
Mix flour, sugar, cinnamon, and salt. Stir in melted butter until crumbly. Set aside. -
Whisk dry ingredients for the cake: flour, baking powder, salt.
-
Cream butter and sugar until light and fluffy. Beat in egg, then vanilla.
-
Add dry ingredients alternately with milk, beginning and ending with dry. Mix just until combined.
-
Fold in blueberries gently.
-
Spread batter in prepared pan. Sprinkle streusel evenly over the top.
-
Bake 40–45 minutes, until golden and a toothpick comes out clean (a few blueberry smears are fine).
-
Cool slightly, then serve warm — ideally with coffee or vanilla ice cream.
Classic Tips
-
Toss blueberries with 1 tsp flour if they’re extra juicy
-
For extra buckle drama: press some streusel lightly into the batter
-
This is better the next day — the crumb gets even softer
If you want, I can give you:
-
a New England–style version
-
a grandma-thin cake / heavy topping ratio
-
or a sour cream or buttermilk upgrade
