🧾 Ingredients
| Ingredient | Amount |
|---|---|
| Frozen wild blueberries | 4 cups (16 oz) |
| Dry lemon cake mix | 1 box (15.25 oz) |
| Unsalted butter, melted | 1/2 cup |
| Granulated sugar | 1/2 cup |
👩🍳 Instructions
Step 1: Prepare the slow cooker
Lightly grease a 4–6 quart slow cooker. Spread the frozen blueberries evenly across the bottom.
Tip: Keeping the berries frozen helps them slowly release juice during cooking, creating a rich fruit filling.
Step 2: Add the sugar
Sprinkle the granulated sugar evenly over the blueberries.
As the dessert cooks, the sugar blends with the fruit juices to create a sweet syrupy layer.
Step 3: Add cake mix and butter
Evenly sprinkle the dry lemon cake mix over the fruit mixture. Slowly drizzle the melted butter across the top. Do not stir.
Tip: A few dry patches are normal and become crisp, buttery bites after cooking.
Step 4: Slow cook
Cover and cook until the filling is bubbling and the topping appears set:
- HIGH: 2 to 2½ hours
- LOW: 3½ to 4 hours
Step 5: Let it rest
Turn off the slow cooker and allow the cake to rest, covered, for about 10–15 minutes before serving.
This helps the filling thicken slightly and makes serving easier.
