• Baking Powder: Ensures the dump cake puffs up lightly, avoiding any heaviness.

• Salt: Enhances all the flavors, making the sweet and tart notes pop.
• Melted Butter (or Coconut Oil): Creates that irresistible golden-brown finish and a decadent, buttery flavor.

How to Make Low Carb Blueberry Dump Cake

Step 1: Prepare the Baking Dish

Begin by preheating your oven to 375°F. Grease an 8×8 inch baking dish with a bit of melted butter or nonstick spray. This will keep your cake from sticking and make serving so much easier!

Step 2: Mix the Blueberry Filling

In a medium mixing bowl, combine your frozen blueberries, sugar-free sweetener, and lemon juice. Give them a good stir so every berry gets coated with sweetener and a hint of citrus. The lemon juice brightens and balances the whole cake.

Step 3: Layer the Blueberries

Spoon the blueberry mixture evenly into your prepared baking dish, spreading out the berries so they form a juicy, colorful base for your Low Carb Blueberry Dump Cake.

Step 4: Make the Crumb Topping

In a separate bowl, whisk together the coconut flour, almond flour, baking powder, cinnamon, and salt. Mixing these dry ingredients before adding them to the fruit ensures a perfectly even, flavorful topping.

Step 5: Add the Crumble Topping

Sprinkle the flour mixture evenly over the blueberries. Don’t worry if it looks a bit rustic—that’s the charm of a good dump cake!

Step 6: Drizzle with Butter

Take your melted butter (or coconut oil if you’re dairy-free) and drizzle it all over the flour topping. This is what gives your Low Carb Blueberry Dump Cake its irresistible golden color and crisp, buttery finish.

Step 7: Bake to Perfection

Pop the dish in the oven and bake for 30–35 minutes, or until you spot bubbly berry goodness around the edges and the topping looks beautifully browned. Let it cool for a bit before serving so the filling can thicken slightly.

How to Serve Low Carb Blueberry Dump Cake

Garnishes

For a little flourish, add a dollop of keto whipped cream or a scoop of your favorite low carb ice cream on top of each serving—the cool and creamy contrast is divine with the warm cake.

Side Dishes

This cake can easily steal the spotlight for dessert, but if you love a full spread, try pairing it with a light fruit salad, a platter of fresh berries, or a simple keto coffee or herbal tea. These options keep things refreshing and don’t overpower the main event.

Creative Ways to Present

If you’re hosting, serve individual portions in small ramekins for a cute, personalized touch. Or, for a more rustic look, let guests scoop their own helpings straight from the baking dish. You could even top each serving with a sprinkle of flaked coconut or crushed nuts for extra crunch and flair.

Make Ahead and Storage

Storing Leftovers

If you find yourself with leftover Low Carb Blueberry Dump Cake (lucky you!), let the cake cool completely, then cover the dish tightly with plastic wrap or a fitted lid. It will keep well in the refrigerator for up to 4 days, and honestly, it might taste even better the next day as the flavors meld together!

Freezing

This dump cake is freezer-friendly! Simply portion out any extras into airtight containers or wrap tightly with foil, then freeze for up to 2 months. Thaw overnight in the fridge when you’re ready for your next blueberry fix—no one will guess it wasn’t freshly baked.

Reheating

To rewarm, pop individual servings in the microwave for 20–30 seconds or reheat the whole dish in a 300°F oven until heated through. The topping will crisp up nicely again in the oven, while the filling becomes warm and oozy—the dream combination!

FAQs

Can I use fresh blueberries instead of frozen?

Absolutely! Fresh blueberries work perfectly in this recipe and bring a slightly firmer texture to the filling. If using fresh, you may want to bake for 5 minutes less, since they won’t release as much moisture as frozen ones.

What’s the best sugar-free sweetener for this recipe?

Use whatever sugar substitute you love most—erythritol, monk fruit blend, or stevia all work beautifully. Just make sure to use a measure-for-measure style sweetener for best results and adjust to taste if needed.

Can I make Low Carb Blueberry Dump Cake dairy-free?

Yes! Simply swap the melted butter for coconut oil. The cake will have a subtle coconut flavor and stay just as rich and delicious.

Will this recipe work with other fruits?

You bet! Blackberries, raspberries, or even a mixture of berries can be substituted for blueberries. Just keep an eye on the bake time, as moisture content varies from fruit to fruit.

Why is it called a “dump cake”?

The magic of a dump cake is how the ingredients are “dumped” into the baking dish with minimal fuss, creating distinct layers that bake together into a perfectly satisfying dessert. No need to stir or carefully arrange—just layer, bake, and enjoy!
