How to Make It
Preheat your oven to 350°F (175°C).
Dump the fresh blueberries into a greased 9×13 inch baking dish.
In a bowl, combine the cake mix, sour cream, melted butter, milk, and lemon zest.
Pour the batter over the blueberries evenly.
Bake for about 30-35 minutes or until golden and bubbly.
Serve
Serve warm with a spoon, letting the sweet blueberry juice pool around the soft cake. It’s the perfect cozy dessert!
