Slow Cooker 4-Ingredient Lemon Blueberry Dump Cake

Step 3: Add Lemon Cake Mix (No Mixing!)

Sprinkle the entire box of dry lemon cake mix evenly over the blueberry layer.

⚠️ Important: Do NOT stir it in.
The “dump cake” magic depends on layering only.

Try to cover all the fruit so every bite gets that buttery cake topping.

Step 4: Add the Butter

Place thin slices of butter evenly over the cake mix OR drizzle melted butter across the surface.

• If using slices: cover as much of the top as possible
• If using melted butter: drizzle slowly for even coverage

The butter is what transforms the dry cake mix into a golden, crisp topping.

Step 5: Slow Cook to Perfection

Cover the slow cooker with a lid and cook:

• LOW: 3.5 to 4.5 hours
• HIGH: 2 to 3 hours

You’ll know it’s ready when:

• The edges are bubbling
• The top is golden and slightly crisp
• The center is thick and jammy

Avoid opening the lid too often—it slows down cooking.

Step 6: Rest Before Serving

Turn off the slow cooker and let the cake sit for about 15–20 minutes.
This helps it thicken and makes scooping easier.

🍽️ How to Serve It

This dessert is best served warm and soft:

• With a scoop of vanilla ice cream
• Topped with whipped cream
• Drizzled with lemon glaze or honey
• Garnished with fresh blueberries or lemon zest

The warm blueberry filling melts into the ice cream—creating a perfect hot-and-cold dessert contrast.

💡 Tips for the Best Dump Cake

• Don’t stir the layers (it ruins the texture)
• Make sure butter covers most of the cake mix
• Use lemon cake mix for best flavor balance
• Frozen blueberries work just as well as fresh
• If the top looks dry halfway through cooking, add a few extra butter slices
