Ingredient Notes

Every component in this buttermilk cake plays a crucial role in creating that perfect texture and flavor balance. Quality ingredients make all the difference when crafting a truly memorable buttermilk cake with buttercream frosting.

• Unsalted butter: Use room temperature butter for proper creaming with sugar, which creates tiny air pockets essential for a light texture. High-quality European-style butters with higher fat content produce an even richer flavor.
• Vegetable shortening: This stabilizes the cake’s structure while adding moisture that pure butter can’t provide. For best results, choose a high-quality, trans-fat-free shortening that won’t leave an aftertaste.
• Granulated sugar: Beyond sweetness, sugar tenderizes the crumb by interfering with gluten development. For extra-fine texture, pulse standard granulated sugar in a food processor before using.
• Eggs: Bring to room temperature for maximum volume when beaten. Fresh eggs with bright orange yolks will enhance the cake’s golden color and richness.
• All-purpose flour: The moderate protein content creates structure without toughness. For an even more tender result, substitute up to 25% with cake flour.
• Buttermilk: The star ingredient that provides moisture, tang, and activates the leavening agents. True cultured buttermilk yields superior results compared to milk with lemon juice substitutes.
• Vanilla extract: Use pure vanilla extract (not imitation) for clean, authentic flavor. Mexican or Madagascar varieties offer distinctive flavor profiles that elevate the entire cake.

How to Make Dreamy Buttermilk Cake

1. Preheat your oven to 350°F (175°C) and prepare two 9-inch round cake pans by greasing them thoroughly and lining the bottoms with parchment paper.
2. Cream together the butter and shortening in a large mixing bowl using an electric mixer on medium speed until completely combined, about 2 minutes.
3. Gradually add the granulated sugar and continue beating until the mixture becomes light and fluffy—I find this takes about 3-4 minutes for that perfect airy texture.
4. Add the eggs one at a time, beating well after each addition and scraping down the sides of the bowl to ensure everything is evenly incorporated.
5. Combine the flour with the baking powder and salt in a separate bowl. In another small bowl, mix the buttermilk with the vanilla extract.
6. Alternately add the dry ingredients and buttermilk mixture to the butter mixture, beginning and ending with the dry ingredients (3 additions of dry, 2 of wet). Mix just until combined after each addition—overmixing now can lead to a tough cake.
7. Divide the batter evenly between the prepared pans, smoothing the tops with a spatula. Bake for 35-40 minutes, or until a toothpick inserted in the center comes out with just a few moist crumbs attached.
8. Let the cakes cool in their pans for 10 minutes before transferring to a wire rack to cool completely. The cakes should feel springy to the touch but make sure they’re completely cool before frosting.

For the best flavor development, consider wrapping the cooled cake layers in plastic wrap and letting them rest overnight before frosting.

Variations & Substitutions

The beauty of this classic buttermilk cake is how wonderfully adaptable it can be to your taste preferences and what’s available in your pantry. Don’t be afraid to make it your own!

• Buttermilk alternatives: No buttermilk on hand? Mix 1 tablespoon white vinegar or lemon juice with enough regular milk to make 1¼ cups and let stand for 5 minutes before using. In a pinch, I’ve used plain yogurt thinned with a little milk with great results.
• Flavor enhancements: Add 1-2 tablespoons of lemon or orange zest to the batter for a citrus twist, or replace ½ teaspoon of vanilla with almond extract for a subtle nutty flavor that pairs beautifully with the buttercream.
• Gluten-free option: Substitute the all-purpose flour with a high-quality 1:1 gluten-free flour blend (one containing xanthan gum). The cake may be slightly less light but will still deliver delicious results—just be careful not to overmix.
• Frosting variations: Switch up the buttercream by adding 4 ounces melted and cooled chocolate, 2 tablespoons lemon juice and zest, or ¼ cup strained strawberry puree for different flavor profiles that still complement the buttermilk cake base.
• Oil substitution: For an even moister cake that stays soft when refrigerated, replace half the butter with a neutral oil like canola or vegetable oil. The texture will be slightly different but wonderfully tender.
• Make it a sheet cake: If layer cakes feel intimidating, this recipe works beautifully in a 9×13″ pan. Bake for about 35-40 minutes and frost directly in the pan for a simpler presentation with all the same delicious flavor.

Make Ahead Options

This Buttermilk Cake with Buttercream Frosting is perfect for meal prep enthusiasts and busy home cooks! You can bake the cake layers up to 3 days in advance—simply wrap them tightly in plastic wrap and store at room temperature (they actually develop better flavor overnight). The buttercream frosting can also be prepared ahead and refrigerated for up to one week; just bring it to room temperature and re-whip briefly before using. For ultimate convenience, assemble the entire frosted cake up to 24 hours before serving and refrigerate covered. When ready to serve, let it sit at room temperature for 30 minutes, and you’ll have bakery-quality results with minimal last-minute effort.

Perfect Pairings & Serving Ideas

This buttermilk cake with buttercream frosting deserves a presentation as lovely as its flavor. The tanginess of the buttermilk and richness of the buttercream create wonderful opportunities for complementary pairings.

• Serve individual slices on vintage dessert plates with a drizzle of warm berry compote for color contrast and a beautiful flavor balance against the buttery sweetness. This makes for an elegant dinner party finale that still feels homey.
• For afternoon tea or coffee gatherings, I like to pair this cake with something mildly bitter to offset the richness—a medium-roast coffee or Earl Grey tea works wonderfully, bringing out the vanilla notes in both the cake and frosting.
• Create a dessert table centerpiece by garnishing the frosted cake with fresh seasonal berries, edible flowers, or candied citrus peel. The bright colors pop against the creamy buttercream, making it irresistible for special occasions.
• For a more substantial dessert experience, serve thin slices alongside a small scoop of high-quality vanilla bean ice cream. The contrast between the room temperature cake and cold ice cream creates a delightful sensory experience.

Storage & Freezing

This buttermilk cake keeps beautifully for several days when properly stored. Place leftover cake in an airtight container or cover it with plastic wrap and store at room temperature for up to 3 days. The buttermilk helps maintain moisture, but you’ll notice the cake stays freshest when the cut sides are protected from air exposure.

For longer storage, this cake freezes exceptionally well. I recommend freezing unfrosted cake layers wrapped individually in plastic wrap and aluminum foil for up to 2 months. The buttercream can also be frozen separately in an airtight container for up to 1 month.

To thaw, place frozen cake layers on the counter at room temperature for 1-2 hours before assembling and frosting. If freezing a fully frosted cake, freeze uncovered until firm, then wrap well and freeze for up to 1 month. Thaw overnight in the refrigerator, then bring to room temperature for 2-3 hours before serving for the best flavor and texture.

Tips for the Best Buttermilk Cake with Buttercream Frosting

Here are some insider tricks to elevate this classic dessert to bakery-quality perfection.

• Room temperature ingredients matter: I’ve found that allowing butter, eggs, and buttermilk to sit at room temperature for 1 hour creates a smoother batter that rises more evenly.
• Don’t rush the creaming: Beat the butter, shortening and sugar for a full 4-5 minutes until truly light and fluffy—this creates the air pockets essential for a tender crumb.
• Measure flour correctly: Spoon flour into measuring cups and level off with a knife rather than scooping directly, which can pack in 25% extra flour and result in a dry cake.
• Check your leavening: Old baking powder loses potency—test yours by adding a teaspoon to hot water; it should bubble vigorously for fresh results in your buttermilk cake.
• Cool completely before frosting: Even slight warmth will melt your buttercream, so refrigerate layers for 30 minutes if you’re in a hurry or working in a warm kitchen.

Ingredients

For the Buttermilk Cake:

• 1 cup (226g) unsalted butter, softened to room temperature
• ½ cup (95g) vegetable shortening
• 2½ cups (500g) granulated sugar
• 4 large eggs, room temperature
• 3 cups (375g) all-purpose flour
• 1 tablespoon baking powder
• ½ teaspoon salt
• 1¼ cups (300ml) buttermilk, room temperature
• 2 teaspoons pure vanilla extract

For the Buttercream Frosting:

• 1½ cups (340g) unsalted butter, softened to room temperature
• 5 cups (600g) confectioners’ sugar, sifted
• ¼ cup (60ml) heavy cream
• 2 teaspoons pure vanilla extract
• ¼ teaspoon salt
• Optional: fresh berries for garnish

Directions

For the Buttermilk Cake:

1. Prepare your workspace: Preheat your oven to 350°F (175°C). Grease two 9-inch round cake pans, line the bottoms with parchment paper, then grease the parchment and lightly flour the pans.
2. Mix dry ingredients: In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
3. Cream fats and sugar: In the bowl of a stand mixer fitted with the paddle attachment (or using a hand mixer), beat the butter and shortening on medium speed until smooth and creamy, about 2 minutes. Gradually add the sugar and continue beating until light and fluffy, about 4-5 minutes. Stop to scrape down the sides of the bowl as needed.
4. Add eggs: Add the eggs one at a time, beating well after each addition (about 30 seconds per egg). Scrape down the bowl after adding the second and fourth eggs.
5. Combine wet ingredients: In a measuring cup or small bowl, stir together the buttermilk and vanilla extract.
6. Alternate additions: With the mixer on low speed, add the flour mixture and buttermilk mixture alternately to the butter mixture, beginning and ending with the flour (3 additions of flour, 2 of buttermilk). Mix just until incorporated after each addition. Be careful not to overmix.
7. Bake: Divide the batter evenly between the prepared pans and smooth the tops with a spatula. Tap the pans gently on the counter to remove any air bubbles. Bake for 35-40 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs attached and the tops are golden.
8. Cool: Allow the cakes to cool in the pans for 10 minutes, then invert onto wire racks, peel off the parchment paper, and let cool completely before frosting, at least 2 hours.

For the Buttercream Frosting:

1. Beat butter: In a large bowl using a hand mixer or stand mixer fitted with a paddle attachment, beat the butter on medium speed until creamy, about 2 minutes.
2. Add dry ingredients: Add confectioners’ sugar, cream, vanilla extract, and salt. Beat on low speed for 30 seconds, then increase to medium-high speed and beat for 3 minutes until light and fluffy. If frosting is too thick, add a bit more cream. If it’s too thin, add more confectioners’ sugar.

Assemble the Cake:

1. Level cakes if needed: Using a long serrated knife, slice a thin layer off the tops of the cakes to create a flat surface if they’ve domed during baking.
2. Start assembly: Place one cake layer on your cake stand or serving plate. Spread about 1 cup of buttercream evenly on top.
3. Finish assembly: Place the second cake layer on top, then frost the top and sides of the cake with the remaining buttercream using an offset spatula.
4. Decorate: For a simple but elegant finish, create swirls in the frosting with the back of a spoon, and garnish with fresh berries if desired.
5. Rest before serving: For the best flavor and texture, let the assembled cake rest at room temperature for at least 1 hour before serving. This allows the layers and frosting to meld together beautifully.

Store leftovers in an airtight container at room temperature for up to 3 days.

Tips for the Best Buttermilk Cake with Buttercream Frosting

Take your cake from good to spectacular with these professional insights that make all the difference.

• Room temperature ingredients are non-negotiable: I’ve learned through many cake failures that cold eggs or buttermilk will cause your batter to curdle and result in a denser cake. Set everything out for a full hour before starting.
• Cream until truly fluffy: Beat the butter, shortening and sugar until the mixture lightens in both color and texture—about 5 minutes. This creates crucial air pockets that give your buttermilk cake its tender crumb.
• Mind your flour measurement: Weighing your flour (375g) yields the most consistent results, but if using cups, always spoon flour into the measuring cup and level with a knife rather than scooping directly.
• Alternate wet and dry carefully: Adding all the flour at once overworks the gluten, while adding all the buttermilk can cause separation. The 3-2 alternating method keeps your batter smooth and properly emulsified.
• Check for doneness properly: Look for the cake to pull away slightly from the edges of the pan and spring back when lightly touched, in addition to the toothpick test. Overbaking even by a few minutes will dry out your cake.
• Chill layers before frosting: For the cleanest frosting job, wrap cooled layers in plastic and refrigerate for 30 minutes before assembling—this firms the cake and prevents crumbs from mixing into your buttercream.

Expert Tips for Buttermilk Cake with Buttercream Frosting

• Fix sinking cake centers: If your cakes consistently sink in the middle, reduce your baking powder to 2½ teaspoons and avoid opening the oven door during the first 25 minutes of baking.
• Prevent dry cake texture: If your buttermilk cake turns out dry, try reducing the bake time by 3-5 minutes—the toothpick should have a few moist crumbs attached, not come out completely clean.
• Solve buttercream separation: If your frosting looks curdled or separated, place the bowl in the refrigerator for 10 minutes, then re-beat until smooth, adding 1-2
