How to Make blueberry dump cake

1. Preheat the oven to 350°F (175°C). In a mixing bowl, combine 2 cups of fresh blueberries (or frozen), 1 cup of granulated sugar, and 1 tablespoon of lemon juice. Pour this sweet mixture into the bottom of a greased 9×13 inch baking dish.

3. Drizzle the melted butter over the cake mix, ensuring even coverage. If you’re feeling adventurous, sprinkle 1 cup of chopped nuts on top for an added crunch!
4. Bake in the preheated oven for 45 minutes, or until the top is golden brown and your kitchen is filled with that irresistible aroma of bubbling blueberries.
