Ingredients

  • 6 cups fresh blueberries
  • 2/3 cup sugar
  • 1 tablespoon cornstarch
  • 2 tablespoons lemon zest divided
  • 1/2 cup butter (plus 1-2 tablespoons more if needed)
  • 15.25 oz. cake mix (I used Betty Crocker Super Moist Yellow)

Instructions

  • Step 1: Prepare the Blueberries. Preheat your oven to 350°F (175°C). In a mixing bowl, combine the fresh blueberries, sugar, cornstarch, and 1 tablespoon of lemon zest. Gently toss until the blueberries are well-coated.
  • Step 2: Layer the Blueberries. Pour the blueberry mixture into the bottom of a greased 9x13-inch baking dish, spreading it evenly.
  • Step 3: Add the Cake Mix. Sprinkle the cake mix evenly over the blueberry layer without mixing it in.
  • Step 4: Melt the Butter. Melt the 1/2 cup of butter and drizzle it evenly over the cake mix.
  • Step 5: Bake to Perfection. Bake for about 45-55 minutes or until the top is golden brown and bubbly.
  • Step 6: Cool and Serve. Let it cool for 10-15 minutes, then serve warm with ice cream or whipped cream!
