🍥 How To Make Blueberry Buckle
- Preheat oven: Heat to 375°F (190°C). Spray a 9-inch square baking dish or pan with nonstick cooking spray.
- Mix dry ingredients: In a medium bowl, whisk together cake flour, baking powder, salt, and ginger.
- Cream butter and sugar: In a large bowl, beat butter and sugar until light and fluffy. Add egg and mix until combined.
- Add wet and dry ingredients: Alternate adding dry mixture and milk to the butter mixture, starting and ending with the dry. Mix until just combined.
- Fold in blueberries: Gently fold in blueberries, being careful not to crush them. Spread batter evenly into prepared pan.
- Make the topping: In a small bowl, combine sugar, flour, and nutmeg. Cut in chilled butter with a pastry cutter or fingers until mixture resembles coarse crumbs.
- Top the cake: Sprinkle streusel evenly over the batter.
- Bake: Bake 45–50 minutes, until topping is golden brown and a toothpick inserted in the center comes out clean.
- Cool and serve: Allow to cool slightly before slicing. Serve warm or at room temperature.
💭 Recipe Tips
- Use fresh blueberries: They hold their shape better than frozen, but frozen berries can work if thawed and drained first.
- Don’t overmix batter: Overmixing makes the cake dense instead of tender.
- Keep butter cold for topping: Cold butter creates a crumbly, crunchy streusel.
- Add lemon zest: A teaspoon of zest in the batter brightens the blueberry flavor.
- Serve warm: This buckle tastes best slightly warm with coffee or tea.
🍧 What To Serve Blueberry Buckle With?
Blueberry buckle is delicious as-is but shines when paired with whipped cream, vanilla ice cream or a drizzle of lemon glaze. Serve it at brunch with fresh fruit, coffee or tea or as a summer dessert after dinner.
🎚 How To Store Blueberry Buckle Leftovers?
- Refrigerate: Store covered in the refrigerator for up to 4 days. Warm in the oven or microwave before serving.
- Freeze: Wrap slices tightly in plastic wrap and foil, then freeze for up to 2 months. Thaw at room temperature and reheat to refresh.
FAQs
Why is it called a “buckle”?
The cake is called a buckle because the streusel topping bakes into the batter, causing the cake to “buckle” or collapse slightly around the berries.
Can I use frozen blueberries?
Yes, but thaw and drain them first to prevent excess liquid from making the cake soggy.
What pan works best?
A 9-inch square baking dish works perfectly, but you can also use a round cake pan or even a springform pan.
Can I make this ahead of time?
Yes, you can bake it the day before and store at room temperature covered. Warm before serving for the best flavor.
