• 5 cups frozen blueberries (do not thaw)

• 2 tablespoons lemon juice
• 1 teaspoon lemon zest (optional)
• 2 tablespoons cornstarch (optional, for a thicker filling)

For the Cake Topping:

🍰 Instructions

Step 1: Prepare the Oven and Dish

1. Preheat your oven to 180°C (350°F).
2. Lightly grease a 9×13-inch casserole dish with butter or cooking spray.

Step 2: Add the Blueberries

1. Pour the frozen blueberries directly into the casserole dish.
2. Spread them evenly across the bottom.
3. Sprinkle sugar, cornstarch, lemon juice, lemon zest, and vanilla over the berries.
4. Gently mix everything together.

Step 3: Add the Cake Layer

1. Sprinkle the dry cake mix evenly over the blueberry layer.
2. Do not stir.
3. Slowly pour melted butter over the entire cake mix, trying to cover as much surface area as possible.
4. Add nuts on top if desired.

Step 4: Bake

1. Place the casserole dish in the oven.
2. Bake for 45–55 minutes until:
   • The top is golden brown.
   • The blueberries are bubbling around the edges.
   • The cake topping is crisp and delicious.
3. Remove from the oven and allow it to cool for about 10–15 minutes before serving.

👩‍🍳 Method and Formation

The secret behind this dessert is the way the layers transform during baking.

The frozen blueberries slowly release their juices as they heat, creating a rich fruit sauce underneath. The dry cake mix absorbs some of the blueberry flavor while the melted butter combines with it to form a golden, crumbly topping.

Unlike traditional cakes that require mixing, measuring, and careful preparation, a dump cake relies on simple layering. The result is a dessert with a texture somewhere between a fruit cobbler and a buttery cake.

The contrast is what makes it special:

• Warm, juicy blueberries underneath.
• Sweet, crispy cake topping above.
• Creamy ice cream melting into every bite.

📜 History of Dump Cakes

Dump cakes became popular in America during the 1960s and 1970s, when home cooks were looking for quick and affordable desserts that used convenient ingredients like boxed cake mixes and canned fruits.

The name “dump cake” comes from the preparation method: ingredients are simply dumped into a baking dish in layers rather than mixed in a bowl.

Over the years, families have created countless versions using cherries, peaches, apples, strawberries, pineapple, and blueberries. Today, dump cakes remain beloved because they combine old-fashioned comfort with modern convenience.
