This lemon blueberry buttermilk cake brings together bright citrus flavors and juicy blueberries in a tender, moist cake that's perfect for spring gatherings or summer celebrations. The tangy cream cheese frosting adds just the right balance of sweetness to complement the fresh fruit flavors.
I first created this cake for my daughter's garden birthday party, and it's become our go-to dessert whenever blueberries are in season. Even my husband, who typically reaches for chocolate desserts, requests this cake specifically when we're entertaining guests.
Ingredients
- Buttermilk: Creates tenderness and adds a subtle tang that enhances the lemon flavor. Look for full-fat buttermilk for best results
- Vegetable oil: Contributes to the cake's moisture and keeps it soft even when refrigerated
- Fresh lemon zest: Contains essential oils that provide intense citrus flavor. Use organic lemons when possible
- Cake flour: Has lower protein content than all-purpose flour resulting in a finer crumb and delicate texture
- Unsalted butter: Adds richness and helps create the cake's velvety structure. Ensure it's properly softened but not melted
- Fresh blueberries: Provide bursts of juicy sweetness. Choose plump berries that are firm and uniform in size
- Cream cheese: Creates a tangy frosting that perfectly complements the lemon cake. Allow it to soften at room temperature for smooth mixing
Step-by-Step Instructions
- Prepare the Pans and Oven:
- Heat your oven to 335°F and prepare three 6-inch round cake pans with your preferred pan release. This moderate temperature ensures even baking without excessive browning.
- Mix the Wet Ingredients:
- Divide the buttermilk and create two mixtures. One with oil, and another containing the eggs, lemon extract, lemon juice, and zest. This careful preparation ensures everything incorporates properly later.
- Combine Dry Ingredients and Butter:
- Place flour, sugar, leavening agents, and salt in your mixer bowl and mix on low speed. Gradually add softened butter until the mixture resembles coarse sand. This technique creates tiny butter pockets that contribute to the cake's tender texture.
- Develop the Batter Structure:
- Add the milk and oil mixture all at once and mix for exactly two full minutes. This critical step develops the cake's structure without overworking the gluten. The timing is precise for a reason.
- Complete the Batter:
- Add the remaining liquid ingredients in three parts, scraping the bowl halfway through. The finished batter should be thick but not runny, indicating the perfect consistency for a tender crumb.
- Prepare and Add Blueberries:
- Toss the blueberries in flour before sprinkling them on top of the batter in the pans. The flour coating prevents berries from sinking, while placing them on top allows them to distribute naturally during baking.
- Bake and Cool Properly:
- Bake until a toothpick comes out clean, then tap the pans on the counter to release air. Cool slightly before carefully turning out onto cooling racks. Wrapping the barely warm cakes prevents moisture loss and makes them easier to handle.

My favorite part of this recipe is the surprising tang that buttermilk brings to the cake. My grandmother always insisted on using buttermilk in her cakes, claiming it was her secret weapon for baking that would make people ask for seconds. After years of baking, I completely understand why. The subtle complexity it adds transforms this from a simple cake into something truly memorable.
The Perfect Cream Cheese Frosting
Creating a silky cream cheese frosting requires attention to detail. The cream cheese and butter must be at the same temperature to blend properly without lumps. Beat them together until completely smooth before adding any powdered sugar. Adding the lemon extract enhances the citrus flavor and creates cohesion between the cake and frosting. If your frosting seems too soft for piping, refrigerate it for 20 minutes before decorating your cake.
Storage and Make-Ahead Tips
This cake stays fresh at room temperature for up to 24 hours. For longer storage, refrigerate for up to 5 days in an airtight container. The cake layers can be frozen individually for up to 2 months. Wrap each layer tightly in plastic wrap, then in aluminum foil before freezing. Thaw overnight in the refrigerator before assembling. The cream cheese frosting can be made up to 3 days ahead and stored in the refrigerator. Allow it to come to room temperature and beat briefly before using.
Seasonal Variations
While fresh blueberries provide the best flavor during summer months, this versatile cake works beautifully with other berries or fruits. Try substituting raspberries or blackberries, or use a mixture for a colorful effect. During winter months, frozen blueberries work perfectly, just be sure not to thaw them before adding to the batter. For a festive holiday version, add cranberries and orange zest instead of lemon for a seasonal twist that still maintains the cake's tender crumb.

Serving Suggestions
This elegant cake deserves a beautiful presentation. For casual gatherings, serve slices with a dollop of lightly whipped cream and additional fresh berries. For more formal occasions, decorate the frosted cake with candied lemon slices and fresh blueberries. A sprig of fresh mint adds a lovely color contrast. Consider serving with a champagne cocktail or a light tea for brunch, or with coffee after dinner for dessert.
