What Is Blueberry Buckle?
Blueberry buckle is an old-fashioned American dessert that sits between a coffee cake and a cobbler. It features a soft, buttery cake batter folded with blueberries, often topped with sugar that creates a crackled, “buckled” surface as the fruit releases juices during baking. The result is a tender cake with pockets of juicy berry flavor and a slightly crisp top.
Ingredients
- Flour mixture — all-purpose flour, baking powder, baking soda, kosher salt, and lemon zest for brightness.
- Wet ingredients — softened salted butter, granulated sugar, eggs, and almond extract (or vanilla).
- Buttermilk — adds tenderness and a slight tang.
- Blueberries — fresh or frozen, divided for folding and topping.
- Additional sugar to sprinkle on top for a crunchy finish.
Use Fresh or Frozen Blueberries
Both fresh and frozen blueberries work well here. Frozen berries release a bit more moisture while baking, which helps keep the cake tender without turning the whole batter blue when tossed lightly with flour first. If berries are out of season, frozen berries are an excellent choice and maintain great flavor.
Easy-to-Make Blueberry Buckle
Preheat and prepare — heat the oven to 350°F and lightly grease a 9×9-inch baking dish or line it with parchment.
Make the dry and wet mixes — whisk together the flour, baking powder, baking soda, salt, and lemon zest in a medium bowl. In another bowl, cream softened butter with sugar until light, then beat in the eggs and almond extract until smooth.
Combine with buttermilk — add the dry ingredients to the wet ingredients in three additions, alternating with buttermilk and folding gently each time to keep the batter tender. The final batter should be semi-thick and soft.
Fold in the berries — toss half the blueberries with a little flour and fold them gently into the batter. Spread the batter into your prepared pan, top with the remaining berries (also tossed lightly with flour if desired), and sprinkle the top with a little extra sugar for a crisp finish.
Bake — bake for about 35–40 minutes, until a toothpick inserted in the center comes out clean and the top is golden and slightly cracked. Let cool for about 10 minutes before slicing into squares. Serve warm or at room temperature.
Pro Tip
Toss blueberries with flour. Whether fresh or frozen, dust the berries that you fold into the batter with a tablespoon or two of flour. This helps prevent them from sinking to the bottom as the cake bakes and keeps the fruit evenly distributed throughout the buckle.
Common Questions
Can I use other berries? Yes. Strawberries, blackberries, raspberries, or a mixed berry combination all work well. Slightly larger berries may benefit from a light chop so they distribute evenly.
Does blueberry buckle freeze well? Yes. The cake freezes nicely—slice into individual squares, wrap tightly, and freeze. Reheat single portions briefly in the microwave for a quick breakfast or snack.
