A quick and easy dump cake combining tangy lemon and sweet blueberries with a golden, buttery crisp crust. Perfect for last-minute desserts or casual get-togethers.

Ingredients

Scale
  • 4 cups fresh or frozen blueberries (about 600 grams / 21 ounces)
  • 1 cup granulated sugar (200 grams / 7 ounces)
  • 1 cup all-purpose flour (125 grams / 4.4 ounces)
  • 1 teaspoon baking powder (4 grams / 0.14 ounces)
  • 1/4 teaspoon salt (1.5 grams / 0.05 ounces)
  • 1/2 cup unsalted butter, melted (115 grams / 8 tablespoons)
  • 2 tablespoons fresh lemon juice (30 ml / 1 fluid ounce)
  • 1 teaspoon lemon zest
  • 1 teaspoon vanilla extract
  • Optional: 1/2 teaspoon ground cinnamon
  • Optional: powdered sugar for dusting

Instructions

  1. Preheat your oven to 350°F (175°C).
  2. In a large bowl, gently toss the blueberries with granulated sugar, lemon juice, lemon zest, and vanilla extract. Let sit for about 5 minutes.
  3. In a separate bowl, whisk together the all-purpose flour, baking powder, salt, and cinnamon if using.
  4. Pour the melted, slightly cooled butter into the dry mixture. Stir with a fork or spatula until crumbly but combined.
  5. Spread the blueberry mixture evenly in a 9×13-inch baking dish.
  6. Sprinkle the crust mixture evenly over the top without stirring or pressing down.
  7. Bake for 40 to 45 minutes until the crust is golden brown and crisp and the blueberry filling is bubbling.
  8. Let the cake rest for at least 15 minutes before serving.

Notes

If the crust browns too quickly, cover loosely with foil halfway through baking. Add 5 extra minutes to baking time if using frozen blueberries. For gluten-free, substitute all-purpose flour with a gluten-free baking blend. For dairy-free, replace butter with coconut oil or plant-based margarine. Avoid overmixing the crust to keep it crisp. Use fresh lemon zest for best flavor.
