    • 6 inch Vanilla Buttermilk Cake

    This vanilla buttermilk cake is my absolute favorite sponge cake recipe! It has the perfect texture, combining the lightness of a sponge cake with a richer, more moist crumb than a traditional genoise sponge. Plus, it keeps its airy crumb without feeling too heavy.

    This vanilla cake is made with buttermilk, a thick, tangy milk that adds a rich flavor and helps make the cake moist and tender. It's like a secret ingredient that makes each bite soft and fluffy. The acidity in the buttermilk reacts with baking soda to give the cake its perfect texture.

    I understand that buttermilk might not be a staple in everyone's pantry, but fear not! You can easily substitute it with regular milk or sour cream and still achieve the same final texture. So, don't let the lack of buttermilk stop you from enjoying this delicious cake!

    Why you'll love this recipe


    • Easy & great recipe: Make this classic vanilla cake recipe at home made with simple ingredients and my tips and tricks for success!
    • Moist and Tender Texture: The buttermilk gives an incredibly soft, moist crumb texture of the cake that melts in your mouth, making it perfect for any occasion.
    • Rich Vanilla Flavor: Infused with the perfect balance of sweet, aromatic vanilla, this cake is simple yet bursting with flavor.
    • Best cake: Its layers are firm and ideal for the stability of a layered cake, whether for a birthday, a wedding cake, and more.

    Ingredients you need

    You need these ingredients to make this perfect 6-inch cake recipe:

    • Butter: Unsalted butter, softened but not melted.
    • Sugar: White granulated sugar only, no brown sugar, muscovado, or powdered sugar.
    • Eggs: Whole eggs at room temperature.
    • Vanilla extract: vanilla essence, vanilla bean paste or seeds from a vanilla pod.
    • Flour: Cake flour only, or all-purpose flour with a bit of cornstarch.
    • Yeast: Baking powder and salt, a mix of baking powder and baking soda that reacts better with buttermilk, and table salt.
    • Buttermilk: if possible, which you can substitute with whole milk or semi-skimmed milk (see recipe card notes).

    How to Make a 6-inch Vanilla Buttermilk Cake

    Here are some quick visual instructions. Don't forget that full instructions with exact ingredients can be found in the main recipe card below!

    Step 1: Beat butter with the sugar in a large bowl with an electric mixer or in the bowl of a stand mixer fitted with the whisk attachment for around 2-3 minutes at medium speed until creamy.

    Step 2: Add the eggs and vanilla extract and beat again at high speed for about 3 - 5 minutes, until the mixture is voluminous.

    Step 3: In a separate medium bowl, mix and sift together the dry ingredients, cake flour, salt, baking powder and baking soda.

    Step 4: Add the flour mixture and buttermilk alternately and in batches, mixing with a rubber spatula or with the paddle attachment of the stand mixer at low speed until you have a smooth, homogenous cake batter.

    Step 5: Divide the batter between 3 6-inch cake pans lined with parchment paper.

    Step 6: Bake the cakes in a preheated oven at 165°C for approx. 30-35 minutes, until golden brown and cooked through in the center.

    Let the cakes cool in their pans for a few minutes, then unmold and place them upside down on a wire rack until completely cooled.

    Cut out the bumps from the vanilla cakes using a cake leveler or saw knife (also remove the crusts if you wish) and use your cooled cakes to assemble your layer cake.

    Fillings & Frosting Ideas

    • Buttercream: Preferably for the exterior like this American buttercream, Swiss buttercream, Italian buttercream, or this Russian buttercream.
    • Mascarpone frostings: Perfect for filling, such as this vanilla mascarpone Chantilly, chocolate mascarpone Chantilly, strawberry mascarpone frosting, raspberry frosting, Oreo frosting, Nutella frosting.
    • Ganache: The perfect covering ganache for the exterior, whipped chocolate ganache, whipped milk chocolate ganache, or whipped vanilla ganache perfect for filling.
    • Fruits purees and curd filling: To accompany or flavor the filling, lemon curd, raspberry compote, strawberry compote, blueberry compote.
    • Others: This salted caramel, peanut butter, homemade praline, or these versions of whipped caramel ganache and whipped Nutella ganache.

    Tips for this recipe

    • Use Room Temperature Ingredients: Leave butter, eggs, and buttermilk out beforehand for a smooth batter consistency.
    • Use Buttermilk: Instead of substitutes, its acidity combined with baking soda forms air bubbles, making the cake light. This acidity also balances sweetness, adding a subtly tangy flavor and a tender cake.
    • Beat Eggs: Whip for at least 3 minutes to incorporate air and achieve a fluffy sponge.
    • Avoid Overmixing: After adding dry ingredients, preferably use a flexible spatula to gently fold in the flour.
    • Mind the Baking: Avoid opening the oven door excessively; check for doneness by inserting a toothpick into the center of the sponge—it should come out clean.
    • Allow Complete Cooling: Before slicing into layers and assembling the layer cake, ensure it cools entirely to prevent fillings from melting against the warm sponge.

    Storage Instructions

    Refrigerator/Room Temperature: The vanilla sponge cake can be stored at room temperature or in the refrigerator, tightly wrapped in plastic wrap or placed in an airtight container for up to 4 days.

    Freezing: You can also freeze it for up to 3 months, tightly wrapped in plastic wrap and placed in a storage container or freezer bags to maintain its flavor. Allow it to thaw gently at room temperature.

    Variations & Substitutions

    • Chocolate Buttermilk Cake: Cocoa powder is added to the batter for an intense chocolate flavor, like in this version of chocolate buttermilk cake.
    • Lemon Buttermilk Cake: Grated lemon zest and sometimes lemon juice are used for a fresh and tangy flavor.
    • Red Berry Buttermilk Cake: Fresh or frozen red berries like raspberries, strawberries, or blackberries are added to the batter for a burst of fruity flavors.
    • Coconut Buttermilk Cake: Shredded coconut is added to the batter for a moist texture and exotic flavor.
    • Coffee Buttermilk Cake: Strong coffee or coffee extract is incorporated into the batter for an intense and rich coffee flavor.
    • Matcha Green Tea Buttermilk Cake: Matcha green tea powder is mixed into the batter for a vibrant green color and a slightly bitter, herbaceous flavor.

    Recipe Questions

    Can I substitute buttermilk in the recipe?

    Yes, if you don't have buttermilk, you can use an equal amount of milk mixed with a little white vinegar or lemon juice. Let it sit for a few minutes to sour before using.

    What if I don't have cake flour?

    If you don't have cake flour, you can make a substitute by measuring out all-purpose flour and replacing two tablespoons of flour per cup with cornstarch. Sift the mixture several times to ensure it's well combined.

    How full do you fill a 6 inch cake pan?

    You typically fill a 6-inch cake pan about halfway full, which is approximately 14 ounces of batter.

    How much does a 6-inch cake serve?

    A 6-inch cake typically serves more like 8 to 10 portions, but it also depends on the height of the cake.

    What does buttermilk do in a cake?

    Buttermilk adds moisture and tenderness to cakes while also providing a subtle tangy flavor. Additionally, its acidity reacts with leavening agents like baking soda to help the cake rise, resulting in a light and fluffy texture.

    Can I make the cake in advance?

    Yes, you can bake the cake layers in advance and freeze them until needed. Wrap each layer tightly in plastic wrap and store in an airtight container or freezer bag. Thaw the layers in the refrigerator before assembling the cake.

    Instructions

    1. Preheat the oven to 165°C (325°F) and prepare three 6-inc/ 15 cm round cake pans by greasing and lining the bottoms with parchment paper. (Alternatively, bake in two 6 inch/ 15 cm pans or in 3 batches in one pan).
    2. In a bowl, mix and sift together the dry ingredients: flour, baking powder, baking soda, and salt.

    Notes

    *For the best baking results, I recommend using a digital scale to measure ingredients in grams instead of cups. Precise measurements ensure consistent and perfect outcomes every time.

    Storage: Up to 3-4 days at room temperature in an airtight container or in the refrigerator, and up to 3 months in the freezer.

     

    Substitute for Buttermilk: Use the same amount of milk with a bit of white vinegar or lemon juice, or an equal mixture of milk and heavy cream, or milk and plain yogurt.

    For an 18 cm (7 inch) pan: Multiply the quantities by 1.2

    For a 20 cm (8 inch) pan: Multiply the quantities by 1.3

    For a 25 cm (10 inch) pan: Multiply the quantities by 1.6

    For a 30 cm (12 inch) pan: Multiply the quantities by 2

    Flavor the batter by adding approximately 50-100 g of spreadable paste, fruit puree, or about 1 teaspoon of spices, citrus zest, extracts, etc.
