Lemon Blueberry Cake with Cream Cheese Frosting

Lemon blueberry cake is a bright, tender dessert made with juicy blueberries, fresh lemon zest, and a soft buttermilk crumb. This lemon blueberry cake is finished with tangy cream cheese frosting, so every slice has a balanced mix of buttery richness, citrus freshness, and sweet berries. It is a lovely spring and summer dessert, but the cheerful flavor makes it welcome whenever you want a homemade celebration cake.

Why This Lemon Blueberry Cake Works

The batter combines softened salted butter with a little vegetable oil for a crumb that is both flavorful and moist. Buttermilk adds gentle tang and helps the cake stay tender, while lemon zest perfumes the entire dessert without making the batter watery. Blueberries appear inside the layers and on top, creating juicy pockets throughout the cake.

The cream cheese frosting is deliberately smooth and lightly lemony. Vanilla rounds out the flavor, and a pinch of salt keeps the sweetness from becoming heavy. The recipe makes 16 servings, enough for a family dessert, a brunch table, or a small birthday gathering.

What You Need for Lemon Blueberry Cake

Ingredients for Lemon Blueberry Cake

For the cake, gather all-purpose flour, granulated sugar, light brown sugar, baking powder, baking soda, salt, softened salted butter, vegetable oil, room-temperature large eggs, vanilla bean paste or vanilla extract, room-temperature buttermilk, one large lemon, and fresh blueberries. Tossing the berries with a little flour helps them stay suspended instead of collecting at the bottom of the pans.

For the frosting, use full-fat brick cream cheese, softened salted butter, confectioners’ sugar, vanilla extract, a pinch of salt, and additional lemon zest. Full-fat cream cheese gives the frosting the best body and makes it easier to spread between the layers.

How to Make Lemon Blueberry Cake

Preheat the oven to 400°F (200°C). Grease and flour three 6-inch or two 8-inch round cake pans. Toss the blueberries with the flour and set them aside. Whisk the flour, baking powder, baking soda, and salt in a large bowl.

Beat the softened butter, oil, granulated sugar, and brown sugar for 2 to 3 minutes, until light and fluffy. Mix in the eggs, vanilla, and lemon zest until just combined. Add the buttermilk and dry ingredients in three alternating additions, beginning and ending with the dry ingredients. Fold in half of the blueberries.

Pour half the batter into the prepared pans and sprinkle the remaining blueberries evenly over it. Spread the remaining batter on top. Bake at 400°F for 5 to 7 minutes, then lower the temperature to 350°F and bake for 20 to 25 minutes, until a tester comes out clean.

Cool the cakes in the pans for 10 minutes, then transfer them to a wire rack to cool completely. Do not frost warm layers because the frosting will soften and slide.

Beat the cream cheese and butter together on medium-high speed for about 2 minutes until smooth and creamy. Add the powdered sugar one cup at a time scraping down the sides every so often to ensure everything is well mixed. Mix in the vanilla extract, lemon zest and a pinch of salt. If the frosting feels too thin, add more powdered sugar a little at a time. If it’s too sweet, a small pinch of salt will balance the flavor. The frosting should be soft but not runny. Spread the frosting generously over your cooled cake. Top with blueberries and enjoy!

Make the Lemon Cream Cheese Frosting

Beat the cream cheese and butter for about 2 minutes until smooth. Add the confectioners’ sugar one cup at a time, scraping down the bowl between additions. Mix in the vanilla extract, lemon zest, and salt. If the frosting feels too thin, chill it briefly; if it is too sweet, a small extra pinch of salt will sharpen the flavor.

Assemble and Decorate

Place one cooled cake layer on a serving plate and spread it with frosting. Add the next layer and repeat, then frost the top and sides. A rustic finish looks beautiful with this cake, so there is no need to make every edge perfectly smooth. Scatter fresh blueberries and a little lemon zest over the top just before serving.

Tips for a Tender Crumb

Measure flour by spooning it into a dry measuring cup and leveling it, or use a scale. Room-temperature eggs and buttermilk blend more easily with the creamed butter. Mix gently after adding flour and stop as soon as the batter is combined. Overmixing develops gluten and can make the cake chewy rather than soft.

Use berries that are dry and firm. If you use frozen blueberries, do not thaw them first. Fold them in while frozen and expect a little extra color in the batter. Check the cake at the early end of the baking range because pan size and oven calibration can change the timing.

Optional Blueberry Lemon Variation

For a sharper citrus finish, stir a teaspoon of finely grated lemon zest into the finished frosting and garnish each slice with a very thin lemon twist. This is an optional variation only; keep the primary recipe balanced with the zest already listed in the ingredients.

Serving and Storage

Serve the cake slightly cool or at room temperature, when the frosting is creamy and the lemon flavor is most noticeable. Refrigerate leftovers in a covered container for up to several days. Let individual slices sit out briefly before serving so the crumb softens and the frosting is not firm from the refrigerator.
