Ingredients for Blueberry Crumble Cake:
To create this delectable Blueberry Crumble Cake, you’ll need just a handful of ingredients. The simplicity of this recipe is part of its charm, making it accessible to bakers of all skill levels. Here’s a list of what you’ll need:

- Blueberries: The star of the show! Use 4 cups of fresh blueberries or frozen blueberries. If using frozen, do not thaw them before adding to the recipe.
- Lemon: A squeeze of fresh lemon juice brightens the flavors and adds a subtle tartness that complements the sweetness of the blueberries. You’ll need the juice of one lemon.
- Brown Sugar: For the best flavor, use 3 tablespoons of brown sugar. The molasses in brown sugar adds a depth and richness that enhances the overall taste of the cake.
- Yellow Cake Mix: This is the secret ingredient that simplifies the recipe. Pick up a box of your favorite yellow cake mix (ensure it is a standard size, typically around 15-18 ounces).
- Unsalted Butter: Use 8 tablespoons (1 stick) of unsalted butter. The butter should be cold and sliced thinly for even distribution over the cake.
How to Make Blueberry Crumble Cake:
Now that you have all your ingredients, let’s get baking! This Blueberry Crumble Cake is surprisingly easy to make, and the results are truly impressive. Follow these simple steps, and you’ll have a warm, delicious cake in no time:
- Preheat the Oven: Start by preheating your oven to 350℉ (175℃). This ensures that the cake bakes evenly and the crumble topping gets perfectly golden brown.
- Prepare the Blueberry Mixture: In a large bowl, combine the blueberries, lemon juice, and brown sugar. Stir well until the brown sugar begins to dissolve. This mixture will form the base of your delicious cake.
- Assemble the Cake: Grease a large baking dish (9×13 inch is ideal) with non-stick cooking spray. Pour the blueberry mixture into the prepared dish, spreading it evenly across the bottom. Then, evenly sprinkle the dry yellow cake mix over the blueberries. Finally, arrange the thin slices of cold butter on top of the cake mix, covering as much of the surface as possible.
- Bake to Perfection: Place the baking dish in the preheated oven and bake for 35-45 minutes, or until the cake is golden brown and the blueberry mixture is bubbly. The crumble topping should be nicely browned and slightly crisp.
- Serve and Enjoy: Once the cake is done, remove it from the oven and let it cool slightly. Serve warm with a scoop of vanilla ice cream for an extra touch of decadence. Enjoy!

This simple recipe yields a truly exceptional cake. The combination of sweet blueberries, tangy lemon, and buttery crumble topping is simply irresistible. And the ease of using a cake mix makes it a perfect dessert for any occasion, whether you’re baking for yourself or for a crowd.
How to Store the Leftovers from the Scrumptious Cake:
If you happen to have any leftovers (which is unlikely!), storing them properly will ensure that they stay fresh and delicious. Here’s how to store your Blueberry Crumble Cake:
Counter: Place the lid on your airtight container and store it on the counter at room temperature for 2-3 days. Keeping it sealed will help maintain its moisture and prevent it from drying out.
Refrigerator: For longer storage, store the cake in the fridge for up to 5 days. Again, make sure to use an airtight container to prevent it from absorbing any unwanted flavors or odors.
When you’re ready to enjoy the leftovers, you can warm them up slightly in the microwave or oven for that fresh-baked taste. A few seconds in the microwave or a few minutes in a warm oven will revive the cake’s texture and flavors.

Tips and Tricks for Making This Moist Coffee Cake Recipe:
To ensure that your Blueberry Crumble Cake turns out perfectly every time, here are a few helpful tips and tricks:
Can I use fresh blueberries?
Yes! If you want to use juicy blueberries you have on hand for this recipe feel free to use those in this easy recipe. Fresh blueberries add a wonderful burst of flavor and texture to the cake. Just make sure to wash and dry them thoroughly before adding them to the mixture.
Lemon juice to use:
When making this blueberry dessert, adding lemon juice is a great way to add a little tart flavor. You could use lemon juice from the bottle which would be about 3 tablespoons, but this has the best results with the fresh lemon.
An added bonus to using a fresh lemon, you could always use the lemon zest to add to the soft cake for even more flavor. Lemon zest will intensify the lemon flavor and add a subtle aroma that complements the blueberries perfectly.
- Don’t Thaw Frozen Blueberries: If using frozen blueberries, add them directly to the mixture without thawing. Thawing them can make the cake batter too wet.
- Use Cold Butter: The cold butter slices are essential for creating the crumble topping. Cold butter will create pockets of steam during baking, resulting in a light and crumbly texture.
- Evenly Distribute the Cake Mix: When sprinkling the cake mix over the blueberries, make sure to distribute it evenly. This will ensure that the crumble topping is uniform and covers the entire cake.
- Adjust Baking Time as Needed: Ovens can vary, so keep an eye on the cake while it’s baking. If the topping starts to brown too quickly, tent the cake with foil to prevent it from burning.
- Let it Cool Slightly: Allow the cake to cool slightly before serving. This will give the flavors a chance to meld together and make it easier to slice.
By following these tips and tricks, you’ll be well on your way to baking a perfect Blueberry Crumble Cake that everyone will love.
