This lemon blueberry cake is the kind of dessert that instantly feels like spring on a plate. It combines a soft lemon cake with juicy blueberries and finishes everything with a creamy, lightly tangy cream cheese frosting. The source recipe also gives two bake options, so you can make it as a simple 9×13 cake or turn it into a layer cake for something a little more special.
What really makes this cake stand out is the balance. The lemon brings brightness, the blueberries add little bursts of sweetness, and the frosting keeps the whole dessert rich without feeling too heavy. The original post specifically highlights the tender crumb, strong lemon flavor, and creamy frosting as the main reasons readers love it.
It is also a practical recipe for home bakers. The method is classic and straightforward: mix the dry ingredients, combine the lemony milk mixture, cream the butter and sugar, then alternate the wet and dry additions before gently folding in the berries. That structure helps keep the cake soft and even-textured.
Another smart detail is the flour-coated blueberries. The source recommends tossing the berries in a little flour first so they are less likely to sink and less likely to bleed too much color into the batter. That one small step makes the finished cake look cleaner and bake more evenly.
This cake also feels flexible enough for different occasions. It is described as a favorite for spring and Easter, but it would work just as well for birthdays, showers, weekend baking, or a dinner dessert when you want something fresh instead of overly rich chocolate. The source especially positions it as a seasonal crowd-pleaser.
The ingredient choices matter here too. Cake flour, buttermilk, fresh lemon juice, and real butter all play a role in creating that soft crumb and bright flavor. The recipe notes are especially firm about using cake flour and fresh lemon juice for the best texture and taste.
And while the layer cake version looks bakery-worthy, the sheet cake version is the easiest way to get all the same flavor with less fuss. The source even recommends the 9×13 version if you want a simpler bake without worrying about stacking and frosting layers.

Ingredients
Lemon Blueberry Cake
- 3 cups cake flour
- 2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 3/4 cup buttermilk, room temperature
- 1/3 cup freshly squeezed lemon juice
- 1 cup unsalted butter, softened
- 1 3/4 cups granulated sugar
- 2 tablespoons lemon zest
- 2 teaspoons vanilla extract
- 4 large eggs, room temperature
- 2 cups blueberries
- 2 teaspoons cake flour or all-purpose flour, for tossing with the berries
Cream Cheese Frosting for a 9×13 Cake
- 1/2 cup unsalted butter, softened
- 8 ounces brick-style cream cheese
- 1 teaspoon freshly squeezed lemon juice
- 3 to 4 cups powdered sugar, sifted
- 1 tablespoon whipping cream, as needed
Cream Cheese Frosting for a Layer Cake
- 3/4 cup unsalted butter, softened
- 12 ounces full-fat brick-style cream cheese
- 1 1/2 teaspoons freshly squeezed lemon juice
- 4 1/2 to 5 1/2 cups powdered sugar, sifted
- 1 to 2 tablespoons whipping cream, as needed
How to Make It
- Prep the pans and oven.
Heat the oven to 350°F. For a sheet cake, grease and flour a 9×13 pan. For layer cakes, line the bottoms of the pans with parchment, then grease and flour the sides. The source strongly recommends lining the bottoms for round cake pans so the layers release more easily. - Mix the dry ingredients.
Sift together the cake flour, baking powder, baking soda, and salt, then whisk to combine. The source notes that cake flour can clump, so sifting matters here. - Combine the buttermilk and lemon juice.
Stir the buttermilk and fresh lemon juice together and set the mixture aside. - Cream the butter, sugar, and zest.
Beat the butter, sugar, and lemon zest until fluffy and lighter in color, about 2 to 3 minutes. - Add the eggs and vanilla.
Mix in the vanilla, then add the eggs one at a time, scraping down the bowl as needed. The source emphasizes adding the eggs gradually to avoid overmixing. - Alternate the wet and dry additions.
On low speed, add about one-third of the dry mixture, then about half of the milk mixture, and repeat until both are incorporated. This alternating method helps keep the crumb even and soft. - Fold in the blueberries.
Toss the berries with a little flour, then gently fold them into the batter. - Bake.
Spread the batter into the prepared pan or divide it between round cake pans. Bake a 9×13 cake for 30 to 35 minutes, or layer cakes for about 25 to 30 minutes, until the top looks set and a toothpick comes out clean. - Cool and frost.
Let the cake cool fully before frosting. For layer cakes, the source recommends chilling the cooled layers before trimming and decorating because cold layers are easier to handle.
Recipe Notes and Tips
Use cake flour if you can. The recipe notes are very clear that a straight one-to-one swap with all-purpose flour will make the cake denser and drier. The source does mention a substitute using all-purpose flour and cornstarch in the notes, but still strongly recommends cake flour for the best result.
Fresh lemon juice makes a difference here. The source specifically advises against bottled juice because fresh juice gives a brighter flavor that tastes lively rather than flat.
Fresh blueberries are the preferred option. The page says frozen berries are more likely to sink and bleed color into the batter, though they can still be used if kept frozen and not thawed first.
For layer cakes, a crumb coat is worth the extra step. The source recommends spreading a thin first layer of frosting, chilling the cake for about 30 minutes, and then finishing with the final frosting layer to keep crumbs out of the exterior.
If you are making the layer cake, refrigerating the cooled layers overnight makes trimming and stacking much easier. That is one of the source’s most practical success tips for a neater finish.
