Cake Ingredients
3cups cake flour (360 grams)
2 teaspoons baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
3/4cup buttermilk (180 ml), room temperature
1/3cup lemon juice (80 ml), freshly squeezed
1cup unsalted butter (226 grams), softened to room temperature
1 3/4cups granulated sugar (350 grams)
2 tablespoons lemon zest
2 teaspoons vanilla extract
4 large eggs, room temperature
2cups blueberries, fresh recommended
2 teaspoons cake flour or all-purpose flour (for tossing blueberries)
Cream Cheese Frosting Ingredients
1/2cup unsalted butter (112 grams), softened
8oz brick-style cream cheese (226 grams)
1 teaspoon lemon juice, freshly squeezed
3 – 4cups powdered sugar (330-440 grams), sifted
1 tablespoon whipping cream, as needed
3/4cup unsalted butter (168 grams), softened
12ounces brick-style cream cheese (340 grams), full fat
Preheat and Prepare Pans Preheat the oven to 350°F (180°C). Grease and flour a 9×13 inch cake pan. For a layer cake, line the bottom of cake tins with parchment paper rounds and grease and flour the sides.
Mix Dry Ingredients In a medium bowl, sift together cake flour, baking powder, baking soda, and salt. Whisk to combine and set aside.
Prepare Buttermilk Mixture Combine the buttermilk and freshly squeezed lemon juice in a separate bowl, whisking them together to create a slightly thickened mixture and set aside.
Cream Butter and Sugar In a large bowl, beat the softened butter, granulated sugar, and lemon zest until light and fluffy, about 2-3 minutes using an electric mixer.
Add Vanilla and Eggs Beat in the vanilla extract. Add eggs one at a time, beating well after each addition. Turn off the mixer and scrape down the bowl sides after each egg to ensure even mixing.
Combine Batter With the mixer on low, add about one-third of the flour mixture, then half of the buttermilk-lemon juice mixture. Turn off the mixer and scrape the bowl. Repeat with another third of the flour and the rest of the buttermilk mixture. Finally, beat in the last third of the flour mixture. Avoid overmixing to maintain a tender cake texture.
Fold in Blueberries Toss blueberries with 2 teaspoons of flour to prevent sinking, then gently fold them into the batter with a spatula or rubber spoon.
Bake the Cake Pour batter into the prepared pan(s). Bake 30-35 minutes for a 9×13 inch pan or 25-30 minutes for layer cakes. Cake is done when the top is set, a toothpick inserted comes out clean, and the cake springs back when lightly pressed.
Cool Let the cakes cool in the pans. For layer cakes, avoid inverting while still hot to prevent breakage.
Make Cream Cheese Frosting Beat butter until soft, then add cream cheese and mix until smooth. Add lemon juice, then gradually beat in powdered sugar starting at low speed and increasing as the sugar is incorporated. Adjust frosting thickness with whipping cream as needed.
Decorate For a 9×13 inch cake, frost the cooled cake and garnish optionally with blueberries and lemon slices. For layer cakes, level domed tops if necessary. Frost between layers, crumb coat the entire cake, chill 20-30 minutes, then finish frosting the top and sides with swirls. Optionally decorate with blueberries.
Serve Slice with a thin, sharp knife to serve.
Notes
Use fresh blueberries for best results.
Tossing blueberries in flour prevents them from sinking to the bottom.
Chill the crumb-coated cake for 20-30 minutes before finishing the frosting to reduce crumbs.
Room temperature ingredients ensure better mixing and texture.
