3. Lemon Blueberry Cream Cheese Dump Cake
Cut 4 oz of cream cheese into small cubes and scatter them over the cake mix layer before adding the butter. The cream cheese melts into creamy pockets, adding richness and a slight tang. This is a cream cheese lemon blueberry dump cake that is extra decadent.
Sprinkle ½ cup of sweetened shredded coconut over the cake mix before adding the butter. The coconut toasts in the slow cooker, adding a tropical crunch.
5. Nutty Lemon Blueberry Dump Cake
Add ½ cup of chopped pecans or walnuts to the top layer. The nuts add crunch and a nutty flavor that complements the fruit. Toast the nuts beforehand for extra flavor.
In a small bowl, mix ½ cup of the dry cake mix with ¼ cup of brown sugar and 2 tablespoons of cold butter (cut in). Sprinkle this streusel over the top before cooking. The result is an extra‑crispy, crumbly topping.
7. Gluten‑Free Lemon Blueberry Dump Cake
Use a gluten‑free lemon cake mix (like King Arthur or Krusteaz). Ensure your pie filling is gluten‑free (most are). The texture will be slightly different but still delicious.
Use a sugar‑free yellow or lemon cake mix (like Duncan Hines keto friendly) and a no‑sugar‑added blueberry pie filling. Use a sugar‑free butter substitute or reduce the amount of butter. This low sugar dump cake is perfect for diabetic diets.
What to Serve with Lemon Blueberry Dump Cake
This dump cake is delicious on its own, but it becomes extraordinary with toppings:
Vanilla ice cream – The classic pairing. The cold, creamy ice cream contrasts the warm, fruity cake.
Whipped cream – Light and airy.
Lemon zest and fresh blueberries – For a fresh, bright garnish.
Powdered sugar dusting – Simple and elegant.
Lemon curd drizzle – For an extra lemony kick.
A dollop of Greek yogurt – For a tangy, protein‑packed twist.
How to Store, Reheat, and Make Ahead
Refrigerator
Store leftovers in an airtight container in the refrigerator for up to 4 days. The dump cake will soften, but the flavor remains excellent. Reheat before serving.
Freezer
This dump cake freezes well. Cool completely, then transfer to a freezer‑safe container. Freeze for up to 2 months. Thaw overnight in the refrigerator. Reheat in the microwave or in a 350°F oven for 10‑15 minutes.
Reheating Best Practices
Microwave: Reheat individual portions for 30‑45 seconds. Oven: Reheat covered at 325°F for 10‑15 minutes. Slow cooker: Reheat on LOW for 1 hour.
Make Ahead for a Party

Frequently Asked Questions
Can I use fresh or frozen blueberries instead of pie filling?
Yes, but you will need to add sugar and a thickener. Mix 4 cups of fresh or frozen blueberries with ½ cup of sugar and 2 tablespoons of cornstarch. Let sit for 10 minutes, then use in place of pie filling. The texture will be slightly different but still delicious.
Can I use a different cake mix flavor?
Yes. White cake mix, yellow cake mix, or even vanilla cake mix work well. Lemon cake mix gives the best complementary flavor. For a different twist, try orange cake mix or vanilla.
Why is my dump cake dry?
A dry dump cake usually means there was not enough butter or the cake was overcooked. Use the full ½ cup of butter, and check for doneness at the lower end of the cooking time. The top should be set but still moist in places.
Can I make this in an oven?
Yes. Preheat oven to 350°F (175°C). Layer ingredients in a 9×13 baking dish. Bake for 35‑40 minutes until bubbly and golden. The oven version is faster and produces a crispier top.
How many calories are in a serving?
One serving (1/8 of the dump cake) contains approximately 380‑450 calories, 18g fat, 58g carbohydrates, and 4g protein. This is a rich, indulgent dessert – perfect for special occasions.
Can I add lemon zest?
Absolutely. Add the zest of 1 lemon to the fruit layer or sprinkle it over the cake mix. The zest adds bright, natural lemon oil flavor.
Can I double this recipe?
Yes. Use a 7‑8 quart slow cooker. Double all ingredients: 2 cans pie filling, 2 boxes cake mix, 1 cup melted butter, ½ cup lemon juice. Cook on HIGH for 3‑3.5 hours. Check for doneness.
The Magic of Dump Cakes
Dump cakes have been a beloved shortcut dessert since the 1970s, when cake mixes became ubiquitous in American pantries. Their appeal lies in their simplicity – you literally “dump” ingredients into a pan or slow cooker and let the magic happen. No mixing bowls, no electric mixers, no complicated steps. The slow cooker version is even more forgiving, as the gentle, even heat prevents burning and allows the fruit to bubble and the cake to crisp slowly. This slow cooker lemon blueberry dessert is a perfect example of why dump cakes have stood the test of time.
