Ingredients for 12 inch white cake
Standard pantry ingredients transformed into restaurant-quality white cake layers with velvety buttercream.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 3 ½ cups | Sifted for even distribution |
| Unsalted Butter 🧈 | 2 cups | Room temperature, European-style preferred |
| Granulated Sugar 🍚 | 2 ½ cups | Superfine preferred for smooth texture |
| Large Eggs 🥚 | 6 whole | Room temperature, separated |
| Powdered Sugar 🍚 | 4 cups | For buttercream, sifted |
| Vanilla Extract 🌿 | 2 tsp | Pure Madagascar preferred |
| Baking Powder 🧂 | 1 ½ tsp | Diamond Crystal brand recommended |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed, for brightness |
| Heavy Cream 🥛 | 1 cup | Cold, for buttercream stability |
| Cornstarch 🌾 | 1 tbsp | For buttercream smoothness |
| Lemon Zest 🍋 | 1 tsp | Fresh, for subtle citrus note |
The butter is non-negotiable here—European-style with at least 82% fat content yields the most tender crumb. Plugrá or Miyoko’s brands deliver consistent results, but any high-quality unsalted butter works if softened properly. For the flour, King Arthur or Gold Medal are reliable choices, but avoid bread flour as it creates a denser texture. Sift both flour and baking powder together to eliminate lumps and ensure even distribution throughout the batter. The eggs must be room temperature—cold yolks can cause the batter to curdle. Separate them carefully to maintain air incorporation during folding.
No superfine sugar? Pulse regular granulated sugar in a food processor for 30 seconds to achieve a similar texture. Substituting powdered sugar for granulated in the cake batter isn't recommended—it alters the crumb structure. For the buttercream, powdered sugar from Domino or C&H works well, but sift it to prevent graininess. The heavy cream should be cold when adding to the buttercream mixture to prevent premature melting. Lemon juice and zest can be omitted if you prefer a neutral flavor profile, but they add a subtle brightness that complements the cake's delicate sweetness. For a dairy-free option, substitute the butter with vegan butter and the heavy cream with coconut cream.
Store cake layers wrapped in plastic wrap at room temperature for up to 2 days or in the refrigerator for 5 days. Buttercream can be refrigerated for 5 days or frozen for 3 months—thaw at room temperature before use. To maintain moisture, place a slice of bread or apple between layers when storing. For best results, assemble the cake within 24 hours of baking. The buttercream can be piped directly onto the cake or spread using an offset spatula for a smoother finish. Cake reheats beautifully in a 300°F (150°C) oven for 10 minutes if slightly dry.
Why You'll Love This Recipe
- No Mixer Needed: I swear by this recipe when my stand mixer’s on vacation. Creaming butter and sugar by hand gives that perfect light texture—no electric fuss, just elbow grease for 5 minutes. The eggs blend right in with a whisk, and the flour folds in like a dream. (Yes, even when I’m distracted by a crying toddler.)
- Vanilla Cloud Magic: That buttery richness? It’s the secret. The cake rises high and fluffy, with a tender crumb that melts in your mouth—no dryness here. Drizzle it with a simple glaze of powdered sugar and milk, and suddenly you’ve got a dessert that tastes like a bakery’s finest. (Pro tip: Let it cool completely, or the glaze turns into a sad puddle.)
- Birthday Party MVP: This cake is my go-to for celebrations because it’s actually easy to decorate. The 12-inch size feeds a crowd without looking overwhelming, and it’s sturdy enough for fondant or whipped cream—no collapsing tiers here. I’ve used it for birthdays, showers, even a last-minute office potluck, and it never disappoints.
- Budget-Friendly Luxury: Honestly, the ingredient list won’t break the bank. Butter and sugar are the stars, but they deliver big flavor without fancy shortcuts. A single batch stretches into two layers (or three if you’re sneaky), and leftovers? They freeze like a champ. Reheat a slice in the oven, and it’s almost as good as fresh. (Almost.)
Step-by-step instructions for 12-Inch white cake
Mastering this recipe delivers professional-quality layers with tender crumb and flawless buttercream.
👨🍳 Step 1: Prepare the Cake Batter
Preheat your oven to 350°F and grease two 12-inch round cake pans with butter and line the bottoms with parchment paper. Sift together the 3.5 cups all-purpose flour, 1.5 teaspoons baking powder, and 0.5 teaspoon salt in a medium bowl. Set aside—this ensures no lumps in your final batter.
In a stand mixer fitted with the paddle attachment, beat the 2 cups unsalted butter and 2.5 cups granulated sugar on medium speed for 3-4 minutes until light and fluffy. You'll see the mixture nearly double in volume and become pale. This creaming process incorporates air, which creates that signature tender crumb.
Add the 6 whole large eggs, one at a time, beating well after each addition. Then mix in the 2 teaspoons vanilla extract, 1 tablespoon lemon juice, and 1 teaspoon lemon zest until just combined. With the mixer running on low speed, gradually add the dry ingredients in three additions, mixing just until incorporated after each. Avoid overmixing—this develops gluten and creates a tough cake.
🍳 Step 2: Bake the Cake Layers
Divide the batter evenly between the prepared cake pans. Tap each pan gently on the counter to remove any air bubbles. Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean. The cake should spring back when touched lightly in the center—this is your visual cue for doneness.
I like to rotate the pans halfway through baking to ensure even browning. If the tops brown too quickly, tent loosely with aluminum foil. Let the cakes cool in the pans for 10 minutes before transferring to a wire rack to cool completely. This gradual cooling prevents cracking as the cakes shrink slightly.
🥘 Step 3: Prepare the Buttercream
In a large mixing bowl, combine the 4 cups powdered sugar, 1 tablespoon cornstarch, and 1 cup heavy cream. Beat with an electric mixer on high speed for 3-4 minutes until smooth and fluffy. This combination creates a stable buttercream that won't melt in warm temperatures.
Add the 2 cups unsalted butter (softened but not melted) and beat for 5-6 minutes until light and airy. The buttercream should be thick enough to hold peaks when piped, but still spreadable. If it's too thick, add 1 teaspoon lemon juice at a time until you reach the desired consistency. For extra flavor, add the remaining 1 teaspoon lemon zest and mix briefly.
🥘 Step 4: Assemble the Cake
Once the cake layers are completely cool, level the tops if necessary using a serrated knife. Place the first layer on a cake stand or plate and spread a thin layer of buttercream on top. This "crumb coat" prevents crumbs from getting into your final frosting. Repeat with the second layer.
Spread a thicker layer of buttercream on the top of the second layer, then place the cake in the refrigerator for 15-20 minutes to firm up slightly. This makes it easier to create clean, professional-looking sides. Use an offset spatula to create a smooth base layer on the sides of the cake, then build up the sides with additional buttercream, creating a slight overhang at the top for that classic cake look.
⏰ Step 5: Decorate and Chill
Once the sides are smooth, add the final top layer of buttercream. Use a bench scraper to create clean, straight edges. For a professional finish, I like to add a simple border of buttercream around the top edge using a piping bag fitted with a small round tip. Chill the cake in the refrigerator for at least 2 hours before serving to allow the flavors to meld and the cake to set properly.
This cake keeps well at room temperature for 2 days or in the refrigerator for up to 5 days. For best results, bring it to room temperature before serving. The combination of tender cake layers and smooth, flavorful buttercream makes this a showstopper for any occasion.
Pro Tips For Making 12 Inch White Cake
- Weigh Your Butter: The difference between 1 cup of packed butter and scooped butter is real—your cake will either rise properly or turn dense. Use a kitchen scale for 227g (1 cup) and pack it firmly into the measuring cup. I learned this after my first cake collapsed like a sad soufflé.
- Separate Eggs Before Whipping: Room-temperature eggs whip better, but if they’re cold, separate them anyway and let the yolks and whites sit in separate bowls for 10 minutes. Warm yolks emulsify more smoothly, and cold whites won’t over-aerate or deflate when you fold them in.
- Don’t Overmix the Batter: Once the flour hits the wet ingredients, stop mixing after just 20 seconds. Overworking the batter develops gluten, which makes your cake tough instead of tender. The second the flour disappears, call it done—no need to stir like you’re making pancakes.
- Bake Until Cool to the Touch: Your cake is done when the center reads 210°F (99°C) and the sides spring back when gently pressed. If you pull it out too soon, it’ll sink in the middle like a sad pancake. Let it cool in the pan for 10 minutes, then transfer—this keeps it from cracking.
Essential equipment for this recipe
Stand Mixer Essentials
Your stand mixer is the workhorse of this recipe—I can’t emphasize this enough. A KitchenAid Artisan or Cuisinart Premium with a paddle attachment is ideal for creaming butter and sugar properly. The paddle attachment ensures even mixing without overdeveloping gluten. If you’re on a budget, the Hamilton Beach 6-Speed works too, but go slow to avoid overheating the butter. 💛
Precision Baking Tools
Invest in two 12-inch round cake pans with removable bottoms—I use Wilton Perfect Results pans for their even heat distribution. Line the bottoms with parchment paper to prevent sticking and ensure clean slices. A serrated cake leveler (like the OXO Good Grips) is a game-changer for creating even layers before frosting. Don’t skip this step—uneven layers ruin the professional look.
Mixing Bowls & Whisks
Use three medium-large mixing bowls (I prefer Pyrex glass for durability). A balloon whisk for the buttercream and a spatula for folding dry ingredients into the batter are non-negotiable. For the buttercream, a hand mixer works, but a stand mixer with a whisk attachment gives you the smoothest, most stable texture. Avoid plastic bowls—they can scratch and harbor residue over time.
Measuring & Sifting
Accurate measurements are critical for a fluffy crumb. Use a digital kitchen scale for the flour and sugar (I trust the OXO Good Grips scale) to avoid packing issues. A fine-mesh sieve (like the Microplane brand) ensures your flour and powdered sugar are lump-free. For the eggs, a separating bowl set (such as Wilton’s) keeps yolks and whites clean—critical for folding air into the batter later.
Decorating Tools
For the buttercream, a piping bag with a Wilton 1M tip creates clean borders, while an offset spatula (like the Ateco 2000) smooths sides like a pro. A bench scraper (I use OXO’s) helps create sharp edges on the cake tiers. If you’re going for a rustic look, skip the piping bag and use a spoon for textured frosting. Chill your tools in the freezer for 10 minutes before use—they glide smoother on cold buttercream.
Temperature Control
A thermometer (like the Thermoworks Thermapen) ensures your oven is at 350°F—critical for even baking. For the butter, use a butter softener (such as the OXO Good Grips) to reach 65–68°F without melting. Cold butter won’t cream properly, while melted butter makes the cake dense. Store your butter in the fridge until ready to soften—this keeps it stable for mixing. 🌡️

Frequently asked questions
Can I substitute cake flour for all-purpose flour in this recipe?
Yes, but you'll need to make adjustments! Replace the 3.5 cups all-purpose flour with 3 cups cake flour plus 1.5 teaspoons cornstarch. Cake flour has a lower protein content, which creates a more tender crumb. If you don't have cake flour, sift together 3 cups all-purpose flour with 1.5 tablespoons cornstarch as a substitute. The extra starch helps achieve that signature light texture.
Why does my white cake turn out dense instead of fluffy?
Overmixing the batter or using cold ingredients are the most common culprits. Always beat the butter and sugar until light and fluffy (about 3-4 minutes), and make sure your eggs and butter are room temperature. Another tip: fold in the dry ingredients gently—just until combined—to avoid developing gluten. Also, don't overfill your cake pans (fill only 2/3 full) to allow proper rising.
How do I prevent cracks from forming on the top of my cake?
Cracks usually appear when the cake cools too quickly or shrinks unevenly. To prevent them, let your cakes cool in the pans for 10 minutes after baking, then transfer to a wire rack to cool completely. Avoid opening the oven door too early, and don't place hot cakes on a cold surface. If cracks do appear, they're purely cosmetic—just frost over them for a smooth finish!
Can I make this cake ahead of time and assemble later?
Bake the layers up to 2 days in advance and store them wrapped tightly in plastic at room temperature. For the buttercream, make it 1 day ahead and refrigerate in an airtight container. When ready to assemble, let the layers and frosting come to room temperature before putting the cake together. Chill the assembled cake for 2 hours before serving for the best texture.
What's the best way to level the cake layers for even frosting?
Use a serrated knife (like a cake leveler) or a long, sharp chef's knife. Place the cake on a cutting board and gently press down with even pressure. For extra precision, use a string level to ensure perfectly even tops. Leveling makes frosting much easier and gives your cake a professional look. Don't worry if you lose a little cake—it's worth it for that clean finish!
