This fluffy lemon blueberry cake recipe makes a tender two-layer 8-inch cake filled with fresh blueberries and finished with creamy lemon cream-cheese frosting.

Every bite combines bright lemon zest, tangy fresh lemon juice, juicy blueberries, and a buttery, soft crumb.

This lemon blueberry cake is designed for a soft, fluffy crumb rather than a heavy or overly dense slice. Creamed butter and sugar provide the cake’s light structure, while buttermilk keeps the texture tender and adds a gentle tang that works beautifully with lemon.
Fresh blueberries create little pockets of juicy fruit throughout both layers. The berries are paired with lemon in three ways: finely grated zest in the batter, fresh lemon juice in the buttermilk, and a fresh lemon finish in the frosting.
The cake is also practical for home bakers. It uses two standard 8-inch round pans, straightforward mixing techniques, and a baking time of only 25–30 minutes.

Ingredients You’ll Need
Gather the ingredients before mixing, and bring the butter, eggs, buttermilk, and cream cheese to room temperature. This small preparation step helps the batter come together evenly and gives the frosting a smoother consistency.
- Flour, baking powder, and salt: These form the cake’s dry foundation and provide structure and lift.
- Butter and sugar: Creamed together for 3–4 minutes, they create a pale, airy base.
- Eggs and vanilla: Eggs add richness and structure, while vanilla rounds out the lemon flavor.
- Lemons: Use finely grated zest from two lemons in the cake, plus fresh juice for the batter and frosting.
- Buttermilk: Its acidity and moisture help produce a tender crumb.
- Blueberries: Fresh berries are ideal, though frozen berries can be used without thawing.
- Frosting ingredients: Full-fat cream cheese, butter, powdered sugar, lemon juice, lemon zest, vanilla, and a small pinch of salt make a creamy, tangy topping.

How to Make It Step-by-Step
Step 1: Heat the oven to 350°F (175°C). Grease two 8-inch round cake pans thoroughly, then line the bottoms with parchment paper so the baked layers release cleanly. Leave the oven fully preheated before the batter goes in.
Step 2: Whisk the 2 cups of flour, baking powder, and fine salt together in a medium bowl. Breaking up any small lumps now helps the dry ingredients distribute evenly later.
Step 3: Place the softened butter and granulated sugar in a large mixing bowl. Beat them for 3–4 minutes, until the mixture looks pale and fluffy; this creaming time is important for the cake’s airy texture.
Step 4: Add the three room-temperature eggs one at a time, beating well after each addition. Mix in the vanilla extract and finely grated zest from two lemons, scraping the bowl if needed so the fragrant zest is evenly dispersed.
Step 5: Stir the 2 tablespoons of fresh lemon juice into the 1/2 cup of room-temperature buttermilk. Combining them before they enter the batter distributes the lemon flavor without adding juice directly to the creamed mixture.
Step 6: Add the dry ingredients to the butter mixture in three additions, alternating with the buttermilk mixture. Begin and end with the dry ingredients, and mix only until no obvious streaks of flour remain; extra mixing can develop gluten and make the cake dense.
Step 7: Toss the 1 1/2 cups of fresh blueberries with 1 tablespoon of all-purpose flour. Fold them gently into the batter with a spatula, using just enough strokes to distribute the berries without crushing them or turning the batter purple.
Step 8: Divide the batter evenly between the two prepared pans and smooth the tops. A quick look at the pan levels helps both layers finish at approximately the same height.
Step 9: Bake for 25–30 minutes, checking near the shorter end of the range. The centers should spring back lightly, and a toothpick should come out clean or with a few moist crumbs attached.
Step 10: Let the cakes cool in their pans for 10–15 minutes, then turn them out onto a wire rack. Cool completely before frosting, since warm layers can soften the cream-cheese frosting and make assembly difficult.
Step 11: For the frosting, beat the softened cream cheese and butter until smooth. Gradually add 3 1/2 to 4 cups of sifted powdered sugar, then mix in 1 tablespoon lemon juice, 1 teaspoon lemon zest, vanilla, and a small pinch of salt.
Step 12: Place one cooled cake layer on a serving plate and spread it with frosting. Add the second layer, then frost the top and sides, creating either a smooth finish or gentle decorative swirls.
Pro Tips for a Fluffy Cake
Room-temperature ingredients are one of the easiest ways to improve this recipe. Cold butter will not cream properly with sugar, and cold eggs or buttermilk can cause the batter to look uneven instead of smooth.
Measure flour carefully by spooning it into a measuring cup and leveling the top, or use the listed 250-gram weight. Too much flour can reduce the cake’s tenderness and make the layers feel heavy.
Do not skip the flour coating for the blueberries. The light coating helps reduce sinking and prevents excess berry juice from streaking through the batter.
Once flour is added, mix gently and briefly. The batter does not need to look perfectly glossy; it only needs to be combined before the berries are folded in.
For frozen blueberries, use them directly from the freezer rather than thawing them. Frozen berries may cause the cake to need a few extra minutes in the oven, so rely on the light spring-back test and toothpick test rather than time alone.
Frosting, Assembly, and Decoration
Allow both cake layers to cool completely before beginning the frosting. If the layers have a slight dome, you can leave them as they are for a generous, home-style appearance or carefully level them for a more polished stack.
Start with a small amount of frosting between the layers and spread it nearly to the edge. The second cake layer will gently push the frosting outward, creating a neat filling without forcing it over the sides.
Apply a thin layer around the outside first if you want to trap loose crumbs, then add the remaining frosting for the final coat. Finish with fresh blueberries and a little lemon zest just before serving for a simple, colorful garnish.

Storage and Serving Suggestions
Because the frosting contains full-fat cream cheese, store the finished cake in the refrigerator. Keep it covered so it does not absorb refrigerator odors, and let slices sit briefly at room temperature before serving for the best texture.
The cake is lovely served cold, but its buttery crumb and lemon aroma become more noticeable after a short rest outside the refrigerator. Use a sharp knife for clean slices, wiping the blade between cuts if you want especially tidy layers.
Serve this cake as a centerpiece dessert with coffee, tea, or a cold glass of milk. Fresh blueberries and lemon zest are enough decoration, though a few thin lemon slices can make the presentation feel especially festive.
