Ingredients
Fruit Mixture
- 6 cups blueberries
- 3 tbsp granulated sugar
- 2 tbsp cornstarch
- 1 tsp pure vanilla extract
- 1 lemon (zested and juiced)
- 1/4 tsp cinnamon
Topping
- 1 box yellow cake mix
- 1/2 cup (1 stick) cold butter, cut into 1/4 inch slices
Instructions
- Preheat Oven: Set your oven to 350°F (175°C) to allow it to reach the perfect baking temperature while you prepare the ingredients.
- Prepare Blueberry Mixture: In a medium bowl, mix together the blueberries, granulated sugar, cornstarch, vanilla extract, lemon zest and juice, and cinnamon. This combination will create a thick, flavorful filling.
- Place in Baking Dish: Spray a 9×13 inch baking dish with cooking spray. Pour the blueberry mixture into the dish, spreading it out evenly.
- Add Cake Mix: Evenly sprinkle the dry yellow cake mix over the blueberry filling. This forms the base of the crispy cake topping.
- Top with Butter: Arrange the slices of cold butter evenly across the top of the cake mix. The butter will melt during baking, creating a rich, golden crust.
- Bake: Place the baking dish in the oven and bake for about 1 hour, until the top is golden brown and the blueberry mixture is bubbly.
- Cool Before Serving: Remove the cake from the oven and let it cool for 10 minutes so the filling can set slightly, making it easier to serve.
Notes
- For a tangier flavor, increase the lemon juice slightly.
- Try using mixed berries or blackberries instead of blueberries for variation.
- Serve with vanilla ice cream or whipped cream for an extra special treat.
- Make sure butter slices are cold to help create a flaky crust.
- Use fresh or frozen blueberries; if frozen, do not thaw before mixing.
