Ingredients
Cake Ingredients
- 3 cups cake flour (360 grams)
- 2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 3/4 cup buttermilk (180 ml), room temperature
- 1/3 cup lemon juice (80 ml), freshly squeezed
- 1 cup unsalted butter (226 grams), softened to room temperature
- 1 3/4 cups granulated sugar (350 grams)
- 2 tablespoons lemon zest
- 2 teaspoons vanilla extract
- 4 large eggs, room temperature
- 2 cups blueberries (fresh recommended)
- 2 teaspoons cake flour (or all-purpose flour) for blueberries
Cream Cheese Frosting
- 3/4 cup unsalted butter (168 grams), softened
- 12 ounces brick-style cream cheese (340 grams), full fat
- 1 1/2 teaspoons lemon juice, freshly squeezed
- 4 1/2 - 5 1/2 cups powdered sugar (495 - 605 grams), sifted
- 1-2 tablespoons whipping cream (as needed)
Instructions
- Preheat and Prepare Pan: Preheat the oven to 350°F (180°C). Grease and flour a 9x13 inch cake pan or, if making a layer cake, line the bottoms of cake pans with parchment rounds and grease and flour the sides.
- Sift Dry Ingredients: In a medium bowl, sift together the cake flour, baking powder, baking soda, and salt, then whisk to combine and set aside.
- Mix Buttermilk and Lemon Juice: Combine the buttermilk and freshly squeezed lemon juice in a small bowl, whisk with a fork, and set aside to curdle slightly.
- Cream Butter and Sugar: In a large bowl, beat the softened butter, granulated sugar, and lemon zest together until fluffy, about 2-3 minutes.
- Add Vanilla and Eggs: Beat in the vanilla extract, then add eggs one at a time, beating well after each addition and scraping the bowl sides as needed.
- Alternate Adding Flour and Buttermilk Mixture: On low speed, add about one-third of the flour mixture followed by half of the buttermilk-lemon juice mixture. Scrape bowl. Repeat with next third of flour, remaining buttermilk mixture, and last third of flour. Mix just until combined; do not overmix.
- Fold in Blueberries: Toss blueberries with 2 teaspoons of flour to prevent sinking and gently fold them into the batter using a spatula or rubber spoon.
- Pour and Bake: Pour batter into prepared pan(s). Bake for 30-35 minutes for a 9x13 pan or 25-30 minutes for layered pans. The cake is done when the top is set, springs back to touch, and a toothpick inserted comes out clean.
- Cool Cake: Allow the cakes to cool completely in their pans. If layer cakes, handle carefully to avoid breaking hot layers.
- Prepare Cream Cheese Frosting: Beat softened butter until soft, then add cream cheese and beat until smooth.
- Add Lemon Juice and Powdered Sugar: Add the lemon juice and 3 cups of powdered sugar gradually, starting on low speed then increasing to medium until combined.
- Adjust Frosting Consistency: Beat in the remaining powdered sugar a half cup at a time until desired sweetness and thickness is reached. If frosting is too thick, beat in 1 tablespoon of whipping cream.
- Decorate Cake: For a 9x13 cake, frost the cooled cake and optionally decorate with blueberries and lemon slices. For layer cakes, level layers if domed and frost between layers and around the cake. Apply a crumb coat then chill for 20-30 minutes before final frosting and decoration.
- Serve: Slice the cake with a thin, sharp knife and serve chilled or at room temperature.
Notes
- Room temperature ingredients ensure better mixing and texture.
- Fresh blueberries are preferred for best flavor and texture, but frozen can be used if tossed in flour first.
- Do not overmix the batter to keep the cake tender and light.
- For a layered cake, chilling layers before frosting helps with clean assembly.
- Adjust frosting thickness by adding powdered sugar or whipping cream as needed.
- Store leftovers covered in refrigerator; bring to room temperature before serving for best flavor.
