Before diving into the magic of making a blueberry lemon crumble cake, let’s chat about what will elevate your dessert experience. This cake is not just a treat but a celebration on a plate. Pair it with a dollop of freshly whipped cream to balance the tartness of the lemons.
A scoop of vanilla ice cream can melt deliciously into the warm cake, creating a delightful contrast in temperature and flavor. For those with a more adventurous palate, a scoop of lavender ice cream adds a floral note that pairs surprisingly well with the berry’s brightness.
Coffee lovers should not overlook a piping hot cup of brewed coffee or even a creamy latte. The depth of coffee enhances the fruity flavors and makes an excellent accompaniment to this cake. If you’re enjoying this during a sunny afternoon, iced tea or sparkling lemonade are refreshing options that work beautifully alongside the cake’s flavors.
Now, let’s move into the heart of things.

Ingredients
For the Crumb Topping:
- 1/2 cup all-purpose flour
- 3/4 cup dark brown sugar
- 1/2 teaspoon ground cinnamon
- 6 tablespoons unsalted butter, melted
For the Cake Base:
- 2 cups all-purpose flour
- 1 1/2 teaspoons baking powder
- 1/4 teaspoon sea salt
- 8 tablespoons unsalted butter, softened
- 1 1/2 teaspoons pure vanilla extract
- 2 large eggs, at room temperature
- 1 cup granulated sugar
- Zest of 1 lemon
- 2/3 cup whole milk
- 2 cups fresh blueberries
- 1/2 teaspoon almond extract
For the Lemon Glaze:
- 1 cup powdered sugar
- Juice of 1/2 lemon
- 1 tablespoon heavy cream
- 1/2 teaspoon lemon zest

Step by Step Directions
Step 1: Prepare Crumble Topping
Start by combining flour, brown sugar, and cinnamon in a mixing bowl. Make sure it’s well combined; this simple step sets the stage for wonderful flavor. Gradually pour in the melted butter and mix until crumbly. You want it to look like wet sand. Set it aside to allow the flavors to meld.
Step 2: Make the Cake Batter
In another bowl, it’s time to whip together your cake base. Beat the softened butter and granulated sugar until it’s light and fluffy. Yes, this step takes a bit of elbow grease, but trust me, it’s worth it. Add in the eggs one at a time, and mix until smooth. Now add lemon zest and vanilla extract, taking a moment to inhale the delightful scents as they meld.
Step 3: Combine Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. Gradually add this mix into your wet ingredients, alternating with the milk. This is how you keep your batter light and fluffy. It should look smooth, and the aroma? Chef’s kiss!
Step 4: Add Blueberries and Almond Extract
Gently fold in your blueberries and almond extract with a spatula. Be careful here; you want to keep those berries intact for bursts of sweetness in each slice!
Step 5: Assemble and Bake
Pour your batter into a greased cake pan, smoothing out evenly. Sprinkle the crumb topping over the batter generously. Pop it into a preheated oven at 350°F (175°C) for 45-50 minutes, or until a toothpick inserted into the center comes out clean. The smell drifting through your home will be heavenly.
Step 6: Prepare the Lemon Glaze
While you wait for the cake to cool, whip together powdered sugar, lemon juice, heavy cream, and lemon zest to create a glaze that will drizzle beautifully over your cooled cake.
Step 7: Glaze the Cake
Once the cake is entirely cool, pour the lemon glaze over top, allowing it to cascade down the sides. This adds an extra layer of sweetness and visual appeal.
Tips on Making Blueberry Lemon Crumble Cake
- Choose Fresh Berries: Opt for ripe, fresh blueberries. They’ll burst with flavor and color, making your cake lively.
- Room Temperature Ingredients: Make sure your eggs and butter are at room temperature for an even batter. Cold ingredients can lead to a dense cake.
- Don’t Overmix: When adding dry and wet ingredients together, mix just until combined. Overmixing can produce a tough texture.
- Cool Before Glazing: Let the cake cool completely before adding the glaze. This prevents the glaze from melting into the cake.
- Zesting Technique: Use a microplane for lemon zest. It ensures you get fine zest without the bitter white pith.

How Do You Store This Blueberry Lemon Crumble Cake?
After making your scrumptious blueberry lemon crumble cake, proper storage is key. You can keep it at room temperature for up to two days. Just cover it with plastic wrap or place it in an airtight container. For longer storage, pop it in the fridge for about a week. Just remember that chilling may firm up the crumble. You can also freeze it for up to two months. Slice it, wrap well in plastic wrap, and then foil or a freezer bag for best results.
What Other Substitutes Can You Use in Blueberry Lemon Crumble Cake?
1. Whole Wheat Flour: For a healthier twist, substitute half of the all-purpose flour with whole wheat flour. This will add an earthy flavor and extra fiber.
2. Coconut Sugar: Replace brown sugar with coconut sugar in both the crumb topping and cake for a darker, rich flavor profile.
3. Greek Yogurt: Swap the milk for Greek yogurt to add protein and keep your cake incredibly moist.
4. Maple Syrup: Use maple syrup instead of granulated sugar for a unique sweet note, but reduce other liquids slightly to maintain the batter’s texture.
5. Frozen Fruit: In a pinch, frozen blueberries can be used. Just toss them in a bit of flour before adding them to the batter to prevent sinking.
