Ingredients:
- 1 can (21 oz) blueberry pie filling
- 2 cups fresh or frozen blueberries
- 1 tbsp fresh lemon juice
- 1 tsp lemon zest
- 1 box (15.25 oz) yellow or white cake mix
- 1/2 cup unsalted butter, melted
Instructions:
- Preheat your oven to 350°F (175°C). Lightly grease a 9x13 inch baking dish with non-stick spray.
- In a large mixing bowl, gently fold together the blueberry pie filling, fresh or frozen blueberries, lemon juice, and zest.
- Pour the mixture into the prepared dish, spreading it with a spatula until the fruit is in an even layer.
- Sift or sprinkle the dry cake mix evenly over the top of the blueberries. Use the back of a spoon to lightly level the powder—do not press it down into the fruit.
- Drizzle the melted butter evenly across the surface of the cake mix, aiming for total coverage without stirring.
- Bake for 40–45 minutes until the edges are bubbling vigorously and the top has turned a deep mahogany-brown and feels firm to a light touch.
