Blueberry Lemon Crumb Cake Ingredients

For the Cake
• Granulated Sugar – Essential for flavor and moisture balance.
• Lemon Zest – Enhances flavor; can be omitted if desired.
• Room Temperature Butter – Provides richness; use unsalted for better control over salt content.
• Neutral Oil (e.g., melted coconut) – Keeps the cake tender; substitutes include vegetable or canola oil.
• Large Eggs (room temperature) – Helps with leavening; use ¼ cup unsweetened applesauce as a substitute for a vegan option.
• Vanilla Extract – Enhances overall sweetness and flavor depth.
• Baking Powder – Ensures the cake rises properly; ensure it’s fresh for best results.
• Salt – Enhances all flavors; can use kosher salt.

• Pinch of Salt – Enhances the sweetness of the cake.

Step‑by‑Step Instructions for Blueberry Lemon Crumb Cake

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it warms up, prepare an 8×8 baking pan by greasing it with cooking spray and lining the bottom with parchment paper. This will ensure your Blueberry Lemon Crumb Cake lifts out easily for serving.

Step 2: Mix Sugar and Lemon Zest
In a large mixing bowl, combine granulated sugar and lemon zest. Using your fingers, rub the zest into the sugar for about 1 minute until fragrant. This crucial step infuses the sugar with citrus aroma, adding depth to your cake’s flavor. Then, add room temperature butter and neutral oil, mixing until the mixture is creamy and smooth.

Step 3: Incorporate Eggs and Vanilla
Next, add in the large eggs and vanilla extract to the creamed mixture. Beat vigorously until the batter is light and fluffy, about 2-3 minutes. The incorporation of air during this step is essential for achieving a delightful texture in the Blueberry Lemon Crumb Cake.

Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking powder, and salt until well blended. Gradually add this dry mixture to the egg mixture, alternating with buttermilk, starting and ending with flour. Stir gently until combined; take care not to overmix, as this could toughen the cake.

Step 5: Fold in Blueberries
To prepare your blueberries for the cake, toss them lightly in a bit of flour to prevent sinking. Gently fold these floured blueberries into the batter until evenly distributed. This step ensures your Blueberry Lemon Crumb Cake will be bursting with juicy blueberries in every bite.

Step 6: Prepare the Crumb Topping
In a medium bowl, mix flour, granulated sugar, optional cinnamon, lemon zest, and a pinch of salt for the crumb topping. Cut in the cold butter with a pastry cutter or your fingers until the mixture resembles coarse crumbs. This crumb topping will add a delightful crunch that complements the softness of the cake.

Step 7: Assemble and Bake
Pour the batter into the prepared baking pan, spreading it evenly. Sprinkle the crumb topping generously over the batter, ensuring that it covers the surface well. Bake in the preheated oven for 42-47 minutes, or until a toothpick inserted in the center comes out clean. The top should be golden brown and fragrant.

Step 8: Prepare the Glaze
While the cake bakes, prepare the glaze by mixing powdered sugar and fresh lemon juice in a small bowl. Whisk until you achieve a smooth, pourable consistency. If the glaze is too thick, add more lemon juice, one teaspoon at a time, until desired. This tangy glaze will enhance the flavor of your Blueberry Lemon Crumb Cake once it cools.

Step 9: Drizzle and Serve
Once the cake has cooled in the pan for about 10 minutes, drizzle the prepared lemon glaze over the top. Allow it to set for a few minutes before cutting into squares and serving. This Blueberry Lemon Crumb Cake is best enjoyed warm or at room temperature, making it perfect for breakfast or dessert gatherings.

Expert Tips for Blueberry Lemon Crumb Cake

Room Temperature Ingredients: Using room temperature butter, eggs, and buttermilk ensures better blending and a fluffier texture in your Blueberry Lemon Crumb Cake.
Don’t Overmix: Mix the batter just until combined. Overmixing can lead to a dense cake, instead of the light, tender crumb you want.
Fresh Blueberries: If using frozen blueberries, do not thaw them as they can release excess moisture. Toss them in flour to prevent sinking.
Golden Brown Top: Keep an eye on the baking time; the cake should be golden and a toothpick should come out clean. Avoid opening the oven door too early.
Chill the Glaze: If your glaze is too runny, refrigerate for a few minutes to thicken it before drizzling over the cooled cake. This will ensure it sets nicely.
Serving Suggestions: Enhance your experience by serving slices with whipped cream or vanilla ice cream. The contrast of cold treats with warm cake is divine!

Blueberry Lemon Crumb Cake Recipe FAQs

How do I know if my blueberries are ripe and fresh?
Absolutely! Look for blueberries that are firm and plump with a deep blue color. Avoid berries with green or reddish hues, as they may not be fully ripe. If you spot dark spots all over, that’s a sign they might be overripe.

How should I store leftover Blueberry Lemon Crumb Cake?
You can store your Blueberry Lemon Crumb Cake in an airtight container at room temperature for up to 3 days. If you prefer it chilled, wrap it tightly in plastic wrap and refrigerate for up to a week. Just be sure to keep it well sealed to retain its moisture!

Can I freeze Blueberry Lemon Crumb Cake?
Yes! To freeze, slice the cake and place the pieces in a single layer on a baking sheet. Once frozen solid, wrap each slice in plastic wrap and store them in a freezer bag for up to 3 months. When you want to enjoy a slice, simply thaw it at room temperature or warm it briefly in the microwave.

What can I do if my cake sinks in the middle?
Very good question! A sinking cake can happen for a few reasons. The most common is underbaking, so ensure you bake it long enough—42-47 minutes should do the trick. Also, avoid opening the oven door before the cake is set, as this can cause it to collapse!

What dietary considerations should I be aware of?
If you have gluten intolerance, you can easily make this Blueberry Lemon Crumb Cake gluten-free by substituting all-purpose flour with a gluten-free blend. Additionally, if you want to make it vegan, replace the eggs with ¼ cup of unsweetened applesauce, and use plant-based butter and milk alternatives. Everyone can enjoy this delicious cake!
