Key Ingredients & Substitutions
All-Purpose Flour: This is the base for your cake. If you’re looking for a gluten-free option, use a 1:1 gluten-free flour blend. Many people find these blends work just as well in baked goods!
Granulated Sugar: This adds sweetness and helps create that lovely crumb. If you’re aiming for a healthier choice, coconut sugar or a sugar substitute like Stevia may work, but keep in mind it might alter the texture slightly.
Butter: Unsalted butter is perfect for controlling the salt level. If you need a dairy-free option, substitute with coconut oil or a vegan butter spread. Just remember, melted butter is generally easier to blend!
Sour Cream or Yogurt: This ingredient adds moisture and a tangy flavor to the cake. Greek yogurt is a great substitute, but you can also use a non-dairy yogurt for a plant-based option without losing the richness.
Blueberries: Fresh blueberries bring sweetness and juiciness. If out of season, frozen blueberries work just fine. Just remember to toss them in a bit of flour to prevent them from sinking in the batter.
How Do I Get That Perfect Crumble Topping?
The crumble topping gives that delightful texture on top of your cake, but it requires some technique. Here’s how to ensure it turns out just right:
- Start with cold butter: It’s crucial for creating that crumbly texture. Cut your butter into small cubes and keep it cold until you’re ready.
- Mix until crumbly: Use a pastry blender or your fingers to combine the butter with the flour and sugar. Stop when it resembles coarse crumbs – this means you’ve done it right!
- Don’t overwork: If you knead it too much, you may end up with a dense topping instead of a light one. Just enough mixing is key!
Following these tips will help you achieve that crunchy, buttery crumble that perfectly complements the soft cake beneath. Enjoy baking!

How Much Time Will You Need?
This delicious Blueberry Lemon Crumble Cake will require about 20 minutes of prep time and around 55 minutes for baking. Allow the cake to cool completely before serving, and you’re looking at a total time of approximately 1 hour and 15 minutes before you can dig in. It’s well worth the wait!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 350°F (175°C). While it heats up, grease and line an 8-inch square baking pan with parchment paper, leaving some overhang for easy removal later.
2. Make the Base:
In a medium bowl, mix together 1 1/2 cups flour, 1/2 cup sugar, salt, and baking powder. Next, add in the melted butter, egg, and vanilla extract. Stir until a smooth dough forms. Press this dough evenly into the bottom of your prepared baking pan. Bake in the oven for about 10 minutes. It should be set but not browned. Once done, remove it and set aside.
3. Prepare the Lemon Cake Batter:
In a large bowl, cream together 1/2 cup softened butter and 1 cup sugar until it’s light and fluffy. Add the eggs one at a time, mixing well after each addition. Then, mix in the sour cream, lemon zest, and lemon juice until combined.
4. Combine Dry Ingredients:
In a separate bowl, whisk together 1 1/4 cups flour, 1 tsp baking powder, and 1/4 tsp salt. Gradually fold the dry ingredients into the wet ingredients, mixing until just combined without overmixing.
5. Layer the Batter and Blueberries:
Pour the lemon cake batter over the pre-baked crust in the baking pan, spreading it evenly. Then sprinkle the fresh blueberries evenly across the lemon batter layer.
6. Make the Crumble Topping:
In another medium bowl, combine 1 cup flour and 1/2 cup sugar. If you’d like a hint of spice, add in the cinnamon as well. Cut in the cold, cubed butter using a pastry blender or a fork until the mixture resembles coarse crumbs.
7. Add the Crumble Topping:
Sprinkle the crumble topping generously over the blueberries and lemon batter layer. Make sure it’s evenly distributed for that perfect crunch.
8. Bake the Cake:
Place the pan in the preheated oven and bake for 45-55 minutes. The crumble topping should turn golden brown, and if you insert a toothpick into the cake layer, it should come out clean.
9. Cool and Slice:
Remove the cake from the oven and allow it to cool completely in the pan on a wire rack. Once cooled, lift the cake out using the overhanging parchment paper and slice it into squares.
10. Garnish and Serve:
For a beautiful presentation, garnish each slice with fresh blueberries and a lemon slice. Enjoy your moist, tangy, and crumbly Blueberry Lemon Crumble Cake!
Can I Use Frozen Blueberries Instead of Fresh?
Absolutely! You can use frozen blueberries for this recipe. Just be sure to toss them in a bit of flour before adding them to the batter to prevent them from sinking while baking.
Can I Make This Cake in Advance?
Yes, you can prepare the cake a day in advance. Just make sure to store it covered at room temperature. For longer storage, wrap it tightly and refrigerate for up to 3 days. Allow it to come to room temperature before serving!
How to Store Leftovers?
Store leftover Blueberry Lemon Crumble Cake in an airtight container at room temperature for up to 3 days. If you want to keep it longer, you can refrigerate it for up to a week. Just allow it to come back to room temperature before enjoying it again.
What Can I Substitute for Sour Cream?
If you don’t have sour cream on hand, plain yogurt is a great substitute! Greek yogurt works best, but any unflavored yogurt will give you similar tanginess and moisture in the cake.
