📝 Instructions:

Step 1: Preheat & Prepare Pan
Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish lightly with butter or non-stick spray.

Step 2: Layer Fruit
Spread blueberries evenly in the prepared pan. If using fresh berries, sprinkle with sugar and lemon juice. Add lemon zest on top for extra flavor.

Step 3: Add Cake Mix
Evenly sprinkle the dry lemon cake mix over the blueberries. Do not stir.

Step 4: Add Butter & Optional Cream Cheese
Drizzle melted butter evenly over the cake mix. If using cream cheese, dollop small spoonfuls across the top.

Step 5: Bake
Bake for 45–50 minutes, or until the top is golden and the fruit is bubbling. Let cool slightly before serving.

Step 6: Serve & Enjoy
Serve warm with whipped cream, ice cream, or enjoy as-is for a quick, fruity treat.
