Tips to Make Blueberry Buckle with Brown Sugar Topping

  • Use fresh blueberries for the best flavor, but frozen blueberries can be used if fresh are not available.
  • Be careful not to overmix the batter to keep the cake tender.
  • Adjust the amount of brown sugar in the topping to suit your preferred level of sweetness.


For a twist on the traditional recipe, you can add a handful of chopped nuts, such as almonds or pecans, to the topping for extra crunch and flavor.


  1. Can I use frozen blueberries instead of fresh ones?
    • Yes, frozen blueberries can be used in this recipe. Thaw and drain them before folding them into the batter.
  2. How can I prevent the blueberries from sinking to the bottom of the cake?
    • Toss the blueberries in a tablespoon of flour before adding them to the batter to help them stay evenly distributed.
  3. Can I substitute the brown sugar in the topping with granulated sugar?
    • The brown sugar brings a caramel-like flavor to the topping, but you can use granulated sugar as a substitute if needed.
