Oven Baked Blueberry Dessert is one of those wonderfully simple old-fashioned recipes that turns a handful of pantry staples into warm homemade comfort with almost no effort. This cozy dessert combines frozen blueberries, sugar, dry cake mix, and melted butter into a bubbling cobbler-style treat with juicy fruit filling and golden buttery topping. As the dessert bakes, the blueberries release sweet syrupy juices while the cake mix transforms into crisp golden crust that tastes incredible with every spoonful.
The beauty of this recipe is how effortless it feels. There is no complicated mixing, no fancy equipment, and no need to thaw the berries first. Everything layers directly into the casserole dish and the oven handles the rest. Whether served after dinner, at potlucks, or during cozy weekends at home, this blueberry dessert delivers warm homemade flavor that always brings people back for seconds.
I first made this blueberry dessert during a cold evening when everyone wanted something sweet but simple. The frozen blueberries were already sitting in the freezer, and the pantry held everything else needed. As the dessert baked, the smell of buttery cake topping and bubbling berries filled the kitchen with the kind of aroma that instantly feels comforting. By the time the casserole dish reached the table with melting vanilla ice cream on top, everyone was already asking for another scoop.

Notes
Why Oven Baked Blueberry Dessert Tastes So Good
Warm Blueberries and Buttery Topping
One reason this dessert feels so comforting is the contrast between juicy blueberries and crisp buttery topping.
As the frozen blueberries bake, they release rich syrupy juices that bubble around the edges of the casserole. Meanwhile, the dry cake mix absorbs melted butter and turns golden brown with slightly crisp texture on top.
The result tastes similar to cobbler or crisp but requires much less effort.
Because the blueberries stay juicy beneath the topping, every bite combines warm fruit with buttery sweetness beautifully.
Easy Dump-and-Bake Simplicity
Another reason this dessert remains so popular is the convenience.
The recipe uses only four ingredients:
- Frozen blueberries
- Sugar
- Yellow cake mix
- Butter
There is no mixing bowl required and no complicated preparation.
Everything layers directly into the baking dish, making cleanup quick and easy while still delivering homemade comfort-food flavor.
Ingredients That Create the Best Dessert
Frozen Blueberries
Frozen blueberries work perfectly because they release juice gradually during baking.
There is no need to thaw them first.
The ice crystals actually help create bubbling syrup as the dessert cooks in the oven.
Blueberries also provide natural sweetness and slight tartness that balance the buttery topping beautifully.
Cake Mix and Butter
Dry yellow cake mix creates the crisp golden topping that forms during baking.
As the melted butter drizzles over the dry mix, parts become crunchy while other areas stay soft and buttery.
The topping tastes rich, sweet, and comforting without requiring homemade batter.
Together, the ingredients create old-fashioned cobbler-style texture with almost no work.
Step-By-Step Baking Instructions
Layering the Dessert
Start by preheating the oven to 350 degrees Fahrenheit.
Lightly grease an 8×8-inch or similar casserole dish.
Spread the frozen blueberries evenly across the bottom of the dish.
Sprinkle the sugar evenly over the berries without stirring.
Next, sprinkle the dry cake mix evenly over the sugared blueberries.
Again, do not mix the layers together.
Baking the Dessert
Slowly drizzle melted butter across the entire surface of the dry cake mix.
Try to moisten most of the topping evenly.
Place the casserole dish into the oven and bake for 40 to 50 minutes until the topping becomes golden brown and the blueberry juices bubble around the edges.
Allow the dessert to cool briefly before serving so the juices thicken slightly.
Serve warm directly from the casserole dish.
