Ingredients

For the Cake

2 and 1/2 cups all-purpose flour, plus 1 tablespoon for coating blueberries
2 and 1/2 teaspoons baking powder
1/2 teaspoon baking soda
1/2 teaspoon fine salt
1 cup (2 sticks) unsalted butter, softened to room temperature
1 and 3/4 cups granulated sugar
3 large eggs, room temperature
2 teaspoons pure vanilla extract
Zest of 2 large lemons (about 2 tablespoons)
3 tablespoons fresh lemon juice
1 cup full-fat sour cream, room temperature
1/4 cup whole milk, room temperature
2 cups fresh or frozen blueberries (do not thaw if frozen)

For the Lemon Cream Cheese Frosting

8 oz full-fat block cream cheese, softened
1/2 cup (1 stick) unsalted butter, softened
3 and 1/2 cups powdered sugar, sifted
2 tablespoons fresh lemon juice
1 teaspoon lemon zest
Pinch of salt

Substitutions & Variations

No sour cream? Use full-fat plain Greek yogurt in an equal swap. It works beautifully and keeps the crumb just as moist.
Dairy-free version: Swap the butter for vegan butter, use coconut cream in place of sour cream, and use oat milk for the milk.
No fresh lemons? Bottled lemon juice works for the juice, but for the zest, fresh lemons are highly recommended since they carry the strongest flavor.
Frozen blueberries: These work perfectly fine. Do not thaw them first, and toss with flour just as you would fresh berries.
Sheet cake option: Pour the batter into a greased 9x13-inch baking pan and bake for 38 to 42 minutes. Skip the layering and frost right on top.
Add a lemon glaze: For a lighter finish, skip the cream cheese frosting and drizzle with a simple mix of 1 cup powdered sugar and 2 tablespoons lemon juice.
Make it a bundt: Grease a standard bundt pan well and bake for 50 to 60 minutes. A lemon glaze over the top looks stunning.

Step-by-Step Instructions

Preheat and Prep Your Pans

Preheat your oven to 350 degrees F. Grease two 9-inch round cake pans and line the bottoms with parchment paper circles. Grease the parchment, then lightly flour the pans and tap out the excess. This prep ensures easy release later.

Coat the Blueberries

Place your blueberries in a small bowl and toss them with 1 tablespoon of all-purpose flour until they are lightly coated. Set aside. This simple step prevents the berries from sinking to the bottom of the cake.

Whisk the Dry Ingredients

In a large bowl, whisk together the 2 and 1/2 cups flour, baking powder, baking soda, and salt. Set this bowl aside. Having your dry ingredients ready means you can move quickly once you start mixing the wet ingredients.

Cream the Butter and Sugar

Using a stand mixer or hand mixer fitted with the paddle attachment, beat the softened butter and granulated sugar together on medium-high speed for about 3 to 4 minutes. You want the mixture to be light, pale, and fluffy. Do not rush this step because creaming properly gives your cake its soft, tender structure.

Add Eggs, Vanilla, and Lemon

Add the eggs one at a time, beating well after each addition. Then mix in the vanilla extract, lemon zest, and lemon juice. Scrape down the sides of the bowl as needed. The batter may look slightly curdled at this point, but that is completely normal and will smooth out once the dry ingredients are added.

Combine Sour Cream and Milk

In a small bowl or measuring cup, stir together the sour cream and milk until combined. This will be added to the batter alternately with the dry ingredients to keep the mixing smooth and even.

Add Dry Ingredients and Wet Mixture Alternately

With the mixer on low speed, add the dry ingredients in three additions, alternating with the sour cream mixture in two additions. Begin and end with the dry ingredients. Mix just until each addition is incorporated. Do not overmix once the flour goes in, as that can make the cake dense and tough.

Fold in the Blueberries

Using a rubber spatula, gently fold in the flour-coated blueberries. Use slow, sweeping motions and stop as soon as the berries are distributed. Be careful not to smash them or the batter will turn purple.

Bake the Cakes

Divide the batter evenly between the two prepared cake pans and smooth the tops with a spatula. Bake for 32 to 38 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs (not wet batter). Start checking at the 32-minute mark.

Cool the Cakes

Let the cakes cool in the pans for 15 minutes, then carefully invert onto a wire cooling rack. Remove the parchment paper and allow the cakes to cool completely before frosting. Frosting warm cakes causes the frosting to melt and slide off.

Make the Cream Cheese Frosting

Beat the softened cream cheese and butter together on medium-high speed until smooth and creamy, about 2 minutes. Reduce to low speed and gradually add the sifted powdered sugar, then add the lemon juice, lemon zest, and salt. Increase speed to medium and beat for another 2 minutes until the frosting is fluffy and spreadable.

Assemble and Frost

Place one cake layer on a serving plate or cake board. Spread a generous amount of frosting over the top. Place the second layer on top, flat side down. Frost the top and sides of the cake. Optionally, garnish with fresh blueberries, lemon slices, or a sprinkle of lemon zest. Refrigerate for at least 30 minutes before slicing for cleaner cuts.

Tips for the Best Results

Room temperature ingredients matter: Cold butter and eggs do not mix properly and can result in a dense, uneven cake. Pull everything out of the fridge 60 to 90 minutes before you start baking.
Measure your flour correctly: Spoon the flour into your measuring cup and level it off with a straight edge. Scooping directly from the bag packs the flour and can add up to 20% more flour than you need.
Zest before juicing: It is much easier to zest a whole lemon than a squeezed one. Always zest first, then juice.
Do not overmix after adding flour: Overmixing develops too much gluten and can make your cake tough. Mix only until you see no more dry streaks.
Check your oven temperature: Oven temperatures can vary by 25 degrees or more. If your cakes consistently overbake or underbake, consider using an oven thermometer.
Use block cream cheese for frosting: Tub-style cream cheese has too much water content and will result in a runny frosting. Always use block cream cheese.

Storage and Reheating

Room temperature (unfrosted): Store the unfrosted cake layers wrapped tightly in plastic wrap at room temperature for up to 2 days.
Refrigerator (frosted): Because of the cream cheese frosting, the assembled frosted cake must be refrigerated. Cover loosely and store for up to 5 days. Let slices sit at room temperature for 20 to 30 minutes before serving for the best texture and flavor.
Freezer: You can freeze the unfrosted cake layers. Wrap each layer tightly in two layers of plastic wrap and then a layer of aluminum foil. Freeze for up to 3 months. Thaw overnight in the refrigerator, then frost and serve.
Reheating: This cake is not typically reheated, but if you like a warm slice, microwave an individual unfrosted slice for 10 to 15 seconds. Do not microwave frosted slices, as the cream cheese frosting can become oily.

Serving Suggestions

This cake shines on its own, but there are so many ways to dress it up or serve it alongside other things for a memorable spread.

Serve with a dollop of lightly sweetened whipped cream and a few fresh blueberries on the side for an elegant plated dessert.
Pair a slice with a cup of hot chamomile, Earl Grey, or green tea. The floral notes complement the lemon and blueberry beautifully.
For a summer brunch, serve alongside a fresh fruit salad, scrambled eggs, and a mimosa bar.
Add a light dusting of powdered sugar over the top right before serving for a bakery-style presentation.
Serve as a birthday cake with candles. The two-layer format is perfect for any celebration.

Frequently Asked Questions

Can I make this cake ahead of time?

Absolutely. You can bake the cake layers up to 2 days in advance. Wrap them tightly in plastic wrap and store at room temperature. Make the frosting the day of assembling for the freshest result, or refrigerate it separately and re-whip it briefly before spreading.

Why did my blueberries sink to the bottom?

The most common culprits are using berries that are too wet or too large, or a batter that is too thin. Make sure to toss the berries in flour and fold them in gently with a spatula. If using frozen berries, do not thaw them first because the extra liquid thins the batter.

Can I make this as cupcakes instead of a layer cake?

Yes, this recipe makes about 24 standard cupcakes. Line a muffin tin with cupcake liners and fill each about two-thirds full. Bake at 350 degrees F for 18 to 22 minutes, or until a toothpick comes out clean. Frost once completely cooled.

My frosting is too runny. How do I fix it?

Runny cream cheese frosting is usually caused by cream cheese that is too warm. Pop the frosting in the refrigerator for 20 to 30 minutes to firm it up, then re-beat it. You can also add more powdered sugar, one tablespoon at a time, until you reach the right consistency.

Can I use a box cake mix as a shortcut?

You can, but the flavor and texture will not be quite the same as this homemade version. If you want to use a mix, take a lemon or white cake mix, swap the water for fresh lemon juice and sour cream, add extra lemon zest, and fold in the flour-coated blueberries. The cream cheese frosting from this recipe will still be wonderful on top.
