There’s something special about a homemade Lemon Blueberry Cake. Every slice is soft, buttery, and filled with juicy blueberries, while fresh lemon juice and zest add a bright citrus flavor that keeps the cake light and refreshing. Finished with a smooth cream cheese frosting, this cake is perfect for birthdays, brunches, holidays, or any time you want an easy dessert that looks as good as it tastes.
Growing up, blueberry season always meant baking with my family. We’d pick fresh berries, grate lemons straight from the kitchen counter, and enjoy the sweet aroma filling the house while the cake baked. Those simple moments inspired this recipe, and it’s still one of my favorite desserts to share with family and friends.

Why You’ll Love This Lemon Blueberry Cake
This Lemon Blueberry Cake is soft, moist, and packed with fresh blueberries in every bite. The combination of tangy lemon and sweet berries creates a perfectly balanced flavor, while the cream cheese frosting adds a rich, creamy finish. It’s easy enough for beginner bakers but elegant enough for birthdays, Easter, Mother’s Day, baby showers, or summer gatherings. You can also make it as a simple sheet cake or a beautiful three-layer cake.
How to Make Lemon Blueberry Cake
Making this Lemon Blueberry Cake is simple when you follow a few easy steps.
Prepare the Batter
Preheat the oven to 350°F (180°C). Grease and flour a 9×13-inch baking pan, or prepare three 8-inch round cake pans if making a layer cake.
In one bowl, whisk together the cake flour, baking powder, baking soda, and salt. In another bowl, combine the buttermilk and fresh lemon juice.
Using a mixer, beat the softened butter, sugar, and lemon zest until light and fluffy. Add the vanilla extract, then beat in the eggs one at a time. Alternate adding the dry ingredients and the buttermilk mixture until everything is just combined. Finally, toss the blueberries with a little flour and gently fold them into the batter.
Bake
Pour the batter into the prepared pan and spread it evenly.
Bake for 30 to 35 minutes for a sheet cake or 25 to 30 minutes for round cake layers. The cake is ready when a toothpick inserted into the center comes out clean and the top springs back lightly when touched.
Let the cake cool completely before frosting.
Cream Cheese Frosting
Beat the softened butter until creamy, then mix in the cream cheese. Add the fresh lemon juice and gradually beat in the powdered sugar until the frosting becomes smooth and fluffy. If needed, add a tablespoon of whipping cream for a softer consistency.
Decorating
Spread the frosting over the cooled cake and decorate with fresh blueberries, thin lemon slices, and a little extra lemon zest.
If you’re making a layer cake, spread frosting between each layer, apply a thin crumb coat, chill for about 20 minutes, then finish with the remaining frosting before decorating.
Tips for a Soft and Moist Lemon Blueberry Cake
For the best texture, use room-temperature butter, eggs, and buttermilk. Fresh blueberries work better than frozen because they hold their shape while baking. Tossing the berries with a little flour helps keep them evenly distributed throughout the cake. Mix the batter only until the ingredients are combined, and always let the cake cool completely before adding the frosting.
Easy Variations
This recipe is easy to customize. Stir white chocolate chips into the batter for extra sweetness, or add raspberries for more berry flavor. Poppy seeds and sliced almonds also pair beautifully with lemon. If you’d like something different, swap the cream cheese frosting for mascarpone frosting or spread homemade blueberry compote between the cake layers.
Storage Tips
Store leftover cake in an airtight container in the refrigerator for up to 4 days. Let each slice sit at room temperature for about 20 minutes before serving.
To freeze, wrap unfrosted cake layers tightly in plastic wrap and freeze for up to 2 months. Thaw overnight in the refrigerator before frosting.
Serving Suggestions
This Lemon Blueberry Cake is delicious with freshly brewed coffee, Earl Grey tea, homemade lemonade, vanilla ice cream, whipped cream, or a spoonful of lemon curd. It makes a beautiful centerpiece for birthdays, spring celebrations, brunches, and summer parties.
Frequently Asked Questions
Can I use frozen blueberries?
Yes. Use them straight from the freezer without thawing. Fresh blueberries still provide the best texture and appearance.
Why did my blueberries sink?
Coating the blueberries with a little flour before folding them into the batter helps prevent them from sinking while baking.
Can I make this cake ahead of time?
Absolutely. Bake the cake layers one day in advance and store them wrapped until you’re ready to frost. You can also freeze unfrosted layers for up to two months.
Can I make cupcakes instead?
Yes. Fill cupcake liners about two-thirds full and bake at 350°F (180°C) for 18 to 22 minutes, or until a toothpick inserted into the center comes out clean.

This Lemon Blueberry Cake combines a soft, buttery crumb with juicy blueberries, bright lemon flavor, and rich cream cheese frosting for a dessert that’s both simple and impressive. Whether you’re baking for a special celebration or treating your family to something homemade, this recipe delivers delicious results every time.

For 9×13 cream cheese frosting:
1/2 cup unsalted butter (112 grams), softened

3/4 cup unsalted butter (168 grams), softened
12 ounces brick-style cream cheese (340 grams), full fat
1 1/2 teaspoons freshly squeezed lemon juice
4 1/2 to 5 1/2 cups powdered sugar (495 to 605 grams), sifted
1 to 2 tablespoons whipping cream, as needed
Instructions
1. Preheat the oven to 350°F (180°C). Grease and flour a 9×13-inch cake pan, or line layer cake pans with parchment rounds, then grease and flour the sides.
2. In a medium bowl, sift together the cake flour, baking powder, baking soda, and salt. Whisk to combine and set aside.
3. In a separate bowl, combine the buttermilk and freshly squeezed lemon juice. Whisk with a fork and set aside.
4. In a large bowl, beat the butter, sugar, and lemon zest until fluffy, about 2 to 3 minutes.
5. Add the vanilla extract, then beat in the eggs one at a time, scraping down the sides of the bowl after each addition.
6. With the mixer on low speed, beat one-third of the flour mixture into the butter mixture. Mix in half of the buttermilk mixture, then scrape down the bowl.
7. Repeat with another third of the flour mixture, the remaining buttermilk mixture, and finally the last third of the flour mixture. Do not overmix.
8. Toss the blueberries with 2 teaspoons of flour, then gently fold them into the batter.
9. Pour the batter into the prepared pan or pans.
10. Bake for 30 to 35 minutes for a 9×13-inch cake, or 25 to 30 minutes for layer cakes, until the top is set and a toothpick inserted in the center comes out clean.
11. Cool the cake completely in the pan before frosting. For layer cakes, cool fully before removing or decorating.
12. For the frosting, beat the butter until soft, then mix in the cream cheese until smooth.
13. Add the lemon juice and 3 cups powdered sugar, mixing on low speed at first, then increasing to medium.
14. Beat in additional powdered sugar 1/2 cup at a time until the desired sweetness and thickness is reached. If needed, beat in whipping cream to loosen the frosting.
15. For a 9×13-inch cake, spread frosting over the cooled cake and decorate with blueberries and lemon slices if desired.
16. For a layer cake, level cooled layers if needed, fill between layers with frosting, apply a thin crumb coat, chill for 20 to 30 minutes, then frost the top and sides.
17. Slice with a thin, sharp knife and serve.
Notes
If you do not have cake flour, use 2 2/3 cups all-purpose flour plus 1/3 cup cornstarch, sifted together three times.
Whole milk may be used instead of buttermilk if needed.
You will need about 3 large lemons for the zest and juice. Zest first, then squeeze.
Use room temperature butter, eggs, and buttermilk for the best texture.
Fresh blueberries are recommended. Frozen blueberries may sink, bleed color, and increase bake time; if using frozen, do not thaw.
Use full-fat brick-style cream cheese for the frosting.
Store leftovers in an airtight container in the refrigerator for up to 4 days.
Unfrosted cake layers may be wrapped tightly and frozen for up to 2 months.
