-
For the Cake:
-
½ cup whole milk
-
½ cup sour cream
-
3 egg whites
-
3 tablespoons fresh lemon juice
-
1 tablespoon lemon zest
-
1 tablespoon vanilla extract
-
2 cups all-purpose flour
-
1⅔ cups granulated sugar
-
1½ teaspoons baking powder
-
¼ teaspoon kosher salt
-
¾ cup unsalted butter
-
1⅓ cups fresh blueberries

-
1½ cups fresh blueberries

1 tablespoon granulated sugar

1 tablespoon fresh lemon juice

1 tablespoon water
-
For the Lemon Buttercream:
-
1½ cups unsalted butter
-
¼ teaspoon kosher salt
-
6 cups confectioners’ sugar
-
3 tablespoons fresh lemon juice
Preheat Your Oven and Prepare the Cake Pans
Start by preheating your oven to 350°F (175°C). While the oven is heating up, take three 6-inch round cake pans, and grease them with butter before dusting with flour to ensure an easy release later on. Pro tip: To help with even baking, consider wrapping the outside of the pans in damp fabric cake strips.
Mix the Wet Ingredients Together
In a medium-sized bowl, whisk together your wet ingredients: whole milk, sour cream, egg whites, lemon juice, lemon zest, and vanilla extract. Mixing these items apart from the dry ingredients ensures they are fully incorporated, making your cake light and fluffy.
Combine the Dry Ingredients and Incorporate
In a separate bowl, sift together the all-purpose flour, granulated sugar, baking powder, and kosher salt. To prevent the blueberries from sinking to the bottom while baking, take about a tablespoon of this flour mixture and toss it with the blueberries in a small bowl. This light coating will keep them suspended.
Incorporate Blueberries and Bake the Cake
In a large mixing bowl or a stand mixer, beat the softened butter until creamy, then gradually mix in the dry ingredients until you reach a sandy texture. With the mixer running, slowly pour in the wet ingredients and mix just until combined. Gently fold in the floured blueberries, then divide the batter evenly among your prepared cake pans. Bake in the preheated oven for about 30 minutes or until the cake tops bounce back when touched.
Make the Blueberry Reduction
While the cakes are baking, prepare the blueberry reduction. Combine 1 cup of blueberries, sugar, lemon juice, and water in a small saucepan over medium-low heat. Mash the berries as they soften, cooking until the mixture reduces by half. Strain this mixture to separate the liquid from the solids, and let it chill.
Craft the Lemon Buttercream
For the buttercream, whip the unsalted butter and salt until fluffy. Gradually add the confectioners' sugar, beating until combined. Add lemon juice until you reach your desired flavor and consistency. Save a cup of this frosting for assembly and mix in the blueberry reduction for a pop of color and taste.
Assemble the Lemon Blueberry Cake
To bring everything together, start with one layer of cake. Pipe a ring of lemon buttercream around the edge, fill it with the blueberry buttercream, and repeat with the next layer. Frost the top and sides with the lemon buttercream, smoothing it out. For a decorative touch, pipe dollops around the top edge and chill the cake for about 20 minutes before slicing.

Cooking Tips and Notes for Lemon Blueberry Cake
Avoiding Sinking Blueberries
Sinking blueberries in your lemon blueberry cake can be a pesky issue! To prevent this, toss the blueberries in a bit of lemon juice to moisten their skins, then coat them lightly with flour. This technique helps suspend the berries in the batter. When pouring the batter, ensure the blueberries are well dispersed to avoid clumping. A simple spoon can help spread them out!
Using Cake Strips for Even Baking
Want your cake layers to bake evenly with a nice, light edge? Consider using wet cake strips! These fabric strips wrap around the outside of your pans and help to regulate temperature, preventing the edges from baking faster than the center. This little trick guarantees beautifully leveled and moist layers for your lemon blueberry cake. For more insights, you might check out Baker's Journal for pro tips!
