Why This Recipe Works
🍳 What You'll Need for This Recipe
Essential tools to make this recipe perfectly
This isn’t just another cake recipe; it’s a carefully crafted symphony of flavors and textures. Here’s why it consistently yields a perfect result:
- The Lemon Infusion: We use both lemon zest and lemon juice to infuse every layer of the cake with that bright, citrusy flavor. The zest releases its aromatic oils, while the juice adds the necessary tang.
- Buttermilk Magic: Buttermilk is the secret ingredient that keeps this cake incredibly moist and tender. Its acidity also helps to activate the baking soda, resulting in a beautiful rise.
- The Right Flour Ratio: We use a combination of all-purpose flour and cake flour. The cake flour has a lower protein content, which contributes to a softer crumb.
- Gentle Mixing: Overmixing develops gluten, leading to a tough cake. We use a gentle hand to ensure a tender crumb.
- Even Baking: Baking the cake at a moderate temperature ensures even cooking and prevents the edges from drying out before the center is done.
- Glaze Perfection: The lemon glaze adds a final layer of sweetness and tartness, creating a truly irresistible cake.
Ingredients
- For the Cake:
- 2 cups all-purpose flour
- 1 cup cake flour
- 1 ½ teaspoons baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
- 1 cup (2 sticks) unsalted butter, softened
- 1 ¾ cups granulated sugar
- 2 large eggs
- 2 large egg yolks
- 1 teaspoon vanilla extract
- 1 cup buttermilk
- ¼ cup lemon juice (from about 2 lemons)
- 2 tablespoons lemon zest (from about 2 lemons)
- 1 ½ cups fresh blueberries
- For the Lemon Glaze:
- 2 cups powdered sugar
- ¼ cup lemon juice (more or less to achieve desired consistency)
- 1 teaspoon lemon zest (optional)

Instructions
- Preheat and Prepare: Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan. This prevents the cake from sticking.
- Combine Dry Ingredients: In a large bowl, whisk together the all-purpose flour, cake flour, baking powder, baking soda, and salt. This ensures even distribution of the leavening agents.
- Cream Butter and Sugar: In a separate bowl, cream together the softened butter and granulated sugar until light and fluffy. This step is crucial for incorporating air into the batter.
- Add Eggs and Yolks: Beat in the eggs and egg yolks one at a time, then stir in the vanilla extract. Adding the yolks separately adds richness and tenderness.
- Alternate Wet and Dry Ingredients: Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk and lemon juice, beginning and ending with the dry ingredients. Mix until just combined. Avoid overmixing.
- Fold in Lemon Zest and Blueberries: Gently fold in the lemon zest and blueberries. Be careful not to crush the blueberries.
- Pour into Pan and Bake: Pour the batter into the prepared baking pan and spread evenly. Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean.
- Cool Completely: Let the cake cool in the pan for 10 minutes before inverting it onto a wire rack to cool completely. Cooling prevents the cake from crumbling.
- Prepare the Glaze: While the cake is cooling, prepare the lemon glaze. In a medium bowl, whisk together the powdered sugar, lemon juice, and lemon zest (if using) until smooth. Add more lemon juice if needed to reach your desired consistency.
- Glaze the Cake: Once the cake is completely cool, drizzle the lemon glaze evenly over the top. Let the glaze set before slicing and serving.
Tips for Success
Here are some tips to ensure your Blueberry Lemon Cake turns out perfectly every time:
- Use Room Temperature Ingredients: Room temperature butter, eggs, and buttermilk emulsify better, resulting in a smoother batter and a more even texture.
- Measure Flour Accurately: Spoon the flour into your measuring cup and level it off with a knife. Avoid scooping directly from the bag, as this can pack the flour and lead to a dry cake.
- Don’t Overmix: Overmixing develops gluten, which can make the cake tough. Mix until just combined.
- Use Fresh Blueberries: Fresh blueberries hold their shape better during baking and provide the best flavor. If using frozen blueberries, toss them in a tablespoon of flour before adding them to the batter to prevent them from sinking to the bottom.
- Adjust Baking Time: Baking times may vary depending on your oven. Start checking for doneness around 30 minutes.
- Let the Cake Cool Completely: Glazing the cake while it’s still warm can cause the glaze to melt and run off.
Storage Instructions
To keep your Blueberry Lemon Cake fresh and delicious, follow these storage instructions:
- Room Temperature: Store the cake in an airtight container at room temperature for up to 3 days.
- Refrigerator: For longer storage, store the cake in an airtight container in the refrigerator for up to 5 days.
- Freezer: You can also freeze the cake for up to 2 months. Wrap it tightly in plastic wrap and then in foil. Thaw overnight in the refrigerator before serving. Note that the glaze may become slightly sticky after thawing.
