I can’t get over this blueberry lemon cake with its tender sour cream layers, juicy berries, bright citrus flavor, and thick cream cheese frosting. It’s the kind of stunning dessert that makes birthdays, holidays, and special occasions feel extra memorable.

I’m obsessed with this Blueberry Lemon Layer Cake because it tastes bright, rich, and totally unapologetic. The lemon flavor hits first, then those juicy fresh blueberries pop through the tender cake like little bursts of tart-sweet drama.

I love a dessert that looks fancy but still feels like something I actually want to attack with a fork. And that cream cheese frosting?

Thick, tangy, swoopy, and exactly what this cake needs. But the best part is the balance.

Sweet, sharp, creamy, bold. No boring bites.

Just a gorgeous cake I’d happily bring to birthdays, holidays, or absolutely nothing special ever.

How to Make this

Print Recipe (No Advertisments)

1. Preheat oven to 350F. Grease and flour two 8 or 9 inch round cake pans and line bottoms with parchment.

2. Whisk together 2 1/2 cups all purpose flour, 1 1/2 teaspoons baking powder, 1/2 teaspoon baking soda, and 1/2 teaspoon fine salt.

3. In a large bowl, cream 1 cup unsalted butter and 1 3/4 cups granulated sugar until light and fluffy, about 3 to 4 minutes. Add 4 eggs one at a time, mixing until incorporated, then stir in 1 tablespoon lemon zest.

4. In a measuring cup combine 1 cup sour cream, 1/2 cup milk, and 1/4 cup fresh lemon juice. Add the dry ingredients to the butter mixture in three additions alternating with the sour cream mixture, beginning and ending with the dry ingredients. Mix just until combined.

5. Gently fold in 1 1/2 to 2 cups fresh blueberries that have been tossed with 1 to 2 tablespoons flour to prevent sinking.

6. Divide batter evenly between prepared pans and smooth tops. Bake until a toothpick inserted in the center comes out clean and cakes are golden, about 25 to 35 minutes depending on pan size. Cool in pans 10 minutes, then remove to wire racks to cool completely.

7. While cakes cool, make frosting. Beat 8 ounces cream cheese and 1/2 cup unsalted butter until smooth. Gradually add 4 cups powdered sugar and beat until creamy. Add 1 teaspoon vanilla extract, 1 to 2 tablespoons fresh lemon juice to taste, and a pinch of salt. Adjust consistency with more powdered sugar if too loose or a teaspoon of milk if too stiff.

8. If desired, level cake layers. Place one layer on a serving plate, spread a generous layer of frosting, then top with the second cake layer and frost the top and sides evenly.

9. Garnish with extra lemon zest and fresh blueberries if desired. Chill briefly to set the frosting before slicing and serving.

FAQ

Q: Can I use frozen blueberries instead of fresh? A: Yes. Do not thaw them first; toss frozen berries in the flour specified and add them straight to the batter. You may need a couple extra minutes of bake time since the cold fruit cools the batter.

Q: How do I keep the blueberries from sinking to the bottom? A: Toss berries in the 1 to 2 tablespoons of flour listed, fold them in gently as the last step, and avoid overmixing the batter. Chilling the filled pans for 10 to 15 minutes can also help.

Q: How should I store the cake and how long will it keep? A: Store assembled cake covered in the refrigerator for up to 4 to 5 days. For unfrosted layers, wrap tightly and refrigerate up to 3 days or freeze up to 3 months.

Q: Can I make components ahead of time? A: Yes. Bake layers 1 to 3 days ahead and keep wrapped in the refrigerator. Frosting can be made and refrigerated up to 5 days; bring to room temperature and rewhip slightly before spreading.

Q: My frosting is too thin or too stiff. How do I fix it? A: If too thin, add sifted powdered sugar a tablespoon at a time and whip until desired thickness. If too stiff, add 1 teaspoon lemon juice or milk at a time until it softens and is spreadable.

Q: Can I substitute Greek yogurt or buttermilk for the sour cream? A: Yes. Use equal amounts of full fat Greek yogurt or cultured buttermilk for similar texture and tang. If using buttermilk, the batter may be slightly looser so keep an eye on bake time.

Blueberry Lemon Layer Cake Recipe Substitutions and Variations

All purpose flour (2 1/2 cups): Substitute with 1) 1:1 gluten free flour blend, same weight (312 g), 2) Cake flour (lighter crumb) use 1 cup plus 2 tablespoons per cup AP, total ~2 1/3 cups, 3) Whole wheat pastry flour use up to 50% substitution and expect denser texture
Unsalted butter (1 cup, 226 g): Substitute with 1) Salted butter, reduce added salt in recipe by about 1/4 teaspoon, 2) Neutral oil (vegetable or canola), use 3/4 cup by volume for 1 cup butter and add 1 tablespoon extra liquid, 3) Vegan butter stick, 1:1 swap for dairy free option
Sour cream (1 cup): Substitute with 1) Full fat Greek yogurt, 1:1, 2) Plain yogurt thinned with a little milk to match consistency, 3) Buttermilk, use 7/8 cup and reduce other liquid slightly
Cream cheese (8 ounces): Substitute with 1) Neufchatel cheese, 1:1 for lower fat, 2) Mascarpone, 1:1 for richer, silkier frosting, 3) Vegan cream cheese, 1:1 for dairy free frosting

Pro Tips

1) Start with truly room temperature ingredients. Cold eggs or butter make the batter dense and can cause the blueberries to sink. Let eggs, butter, milk and sour cream sit out for about 30 to 60 minutes before you begin.

2) Coat the berries lightly in flour and fold them in very gently at the end. That thin flour layer helps them stay suspended, and minimal folding keeps the batter light so the cake rises evenly.

3) Watch the bake rather than the clock. Oven temperatures vary, so begin checking at the early end of the time range. A clean toothpick or a few moist crumbs mean done. If the tops brown too quickly, tent loosely with foil for the last 10 minutes.

4) Chill the frosted cake briefly before slicing. Pop the assembled cake in the fridge for 20 to 30 minutes to help the frosting set and make cleaner slices. If your frosting seems a bit loose, a touch more powdered sugar or a short chill will firm it up without changing the flavor.
