Ingredients

• 1 (15.25-ounce) box lemon cake mix

Equipment

• 6-quart slow cooker
• Mixing bowl (optional)

Step 2

Spread the blueberry pie filling evenly over the bottom.

Step 3

Scatter the fresh blueberries evenly over the pie filling.

Step 4

Sprinkle the dry lemon cake mix evenly over the fruit layer. Do not stir.

Step 5

Slowly drizzle the melted butter over the entire surface, covering as much of the cake mix as possible.

Step 6

Cover with the lid.

Cook on:

• High: 2–2½ hours

The topping should be lightly golden and mostly set.

Step 7

Recipe Notes

Frequently Asked Questions (Q&A)

1. Why is it called a dump cake?

Because the ingredients are simply layered or “dumped” into the slow cooker without mixing.

2. Can I use frozen blueberries?

Yes. Add them directly from frozen without thawing.

3. Can I use another cake mix?

Absolutely. Yellow, white, vanilla, or butter cake mix all work well.

4. Can I make this in the oven?

Yes. Bake in a greased 9×13-inch baking dish at 350°F (175°C) for 40–50 minutes.

5. Why are there dry spots on top?

Small dry patches are normal. For a more even topping, drizzle the butter carefully to cover as much of the cake mix as possible.

6. Can I use homemade blueberry filling?

Yes. Homemade blueberry pie filling works wonderfully and often provides fresher flavor.

7. Can I reduce the sweetness?

Use homemade blueberry filling with less sugar or replace part of the pie filling with fresh blueberries.

8. What size slow cooker is best?

A 6-quart slow cooker provides the most even cooking.

9. Can I double the recipe?

Yes, if using a larger slow cooker (7–8 quarts). Increase the cooking time slightly and check for doneness.

10. What pairs best with this dessert?

Vanilla ice cream, whipped cream, lemon curd, or a hot cup of coffee or tea complement it beautifully.
