A quick and fuss-free dessert combining fresh lemon zest and juice with juicy blueberries and a crisp yellow cake mix topping. Perfect for last-minute guests or casual gatherings.

Ingredients

Scale
  • 1 box yellow cake mix (about 15.25 oz or 432 g)
  • 4 cups blueberries (about 600 g), fresh or frozen
  • 3/4 cup granulated sugar (150 g)
  • Zest and juice of 1 large lemon
  • 1/2 cup unsalted butter (1 stick or 113 g), melted
  • 1 teaspoon vanilla extract (optional)
  • Pinch of salt (optional)

Instructions

  1. Preheat your oven to 350°F (175°C).
  2. In a large mixing bowl, combine the blueberries with sugar, lemon zest, lemon juice, vanilla extract, and a pinch of salt. Toss gently to coat evenly.
  3. Pour the blueberry mixture into your greased 9×13-inch baking dish and spread evenly.
  4. Sprinkle the entire box of yellow cake mix evenly over the fruit without mixing it in.
  5. Drizzle the melted butter evenly over the cake mix layer.
  6. Bake for 45-50 minutes at 350°F (175°C), checking around 40 minutes to prevent burning.
  7. Remove from oven and let cool for 10-15 minutes before serving.

Notes

Use fresh lemon zest and juice for best flavor. Do not stir the cake mix into the berries to maintain a crisp topping. Melted butter is essential for even browning. Check baking time as ovens vary. Let the cake cool before serving to allow filling to thicken. Frozen blueberries can be used without thawing but may require extra baking time.
