Ingredients for 1kg vanilla cake
Twelve ingredients, meticulously balanced for a cake that stands tall and proud.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 3 cups | Sifted for even texture |
| Cake Flour 🌾 | 1 cup | Essential for tender crumb |
| Cornstarch 🌾 | 2 tbsp | Prevents gumminess |
| Unsalted Butter 🧈 | 1 lb | Room temperature, cubed |
| Granulated Sugar 🍚 | 2 cups | Superfine preferred |
| Vanilla Extract 🍋 | 2 tbsp | Pure Madagascar preferred |
| Large Eggs 🥚 | 4 whole | Room temperature |
| Whole Milk 🥛 | 1 cup | Room temperature |
| Baking Powder 🧂 | 2 tsp | Aluminum-free preferred |
| Salt 🧂 | ½ tsp | Diamond Crystal kosher |
| Vegetable Oil 🫒 | ½ cup | Light, not heavy |
The foundation of a stable cake begins with the flour blend. Cake flour delivers the tender crumb essential for supporting fondant, while all-purpose flour adds structure. For the best results, source King Arthur cake flour or make your own by removing 2 tbsp of flour from 1 cup all-purpose and adding 2 tbsp cornstarch. The unsalted butter must be room temperature—cold butter creates air pockets that lead to collapse. European-style butter like Plugrá has higher fat content, ideal for this recipe. Measure your sugar precisely; superfine sugar dissolves faster, preventing graininess in the final crumb.
No cake flour? Replace with all-purpose flour by removing 2 tbsp from the 1 cup measurement and adding 2 tbsp cornstarch. For the vanilla, pure Madagascar extract has the most complex flavor, but imitation works in a pinch. Room temperature eggs prevent lumps, but if yours are cold, let them sit in warm water for 10 minutes. The vegetable oil acts as a tenderizer—use light oil like canola or safflower. For a richer flavor, substitute 0.25 cup of the milk with heavy cream, but expect a slightly denser crumb. Diamond Crystal baking powder is preferred over other brands due to its consistent rise.
Store the cake in an airtight container at room temperature for up to 3 days or refrigerate for 5 days. For longer storage, wrap tightly in plastic and freeze for up to 3 months. When ready to decorate, bring the cake to room temperature for 1-2 hours before applying fondant to prevent cracking. The cake’s structure allows it to support up to 2 lbs of fondant without sagging, making it ideal for multi-tier designs. Slice with a serrated knife dipped in hot water for clean cuts.
Why You’ll Love This Recipe
- No Mixer Needed: Between us, this cake is so forgiving. The butter and sugar get creamed by hand in minutes—no stand mixer, no fuss—and the cake flour keeps it light without requiring perfect folding. I’ve made it in a hotel room kitchen with a fork and butter knife, and it still turned out tender.
- Vanilla Kiss: That first bite? Pure, warm vanilla that lingers like a hug. The cornstarch (don’t skip it!) gives it this just-right crumb—moist but never gummy—while the all-purpose flour adds structure. Honestly, my coffee cake version with this base gets rave reviews, and it’s all thanks to that simple vanilla magic.
- Party or Picnic: This recipe is my secret weapon for crowds. A 1kg pan feeds 8–10 easily, and it’s sturdy enough for slicing—no crumbling when you cut it. I’ve taken it to potlucks, birthday parties, and even packed slices for lunchboxes. The butter richness means it holds up, and the neutral flavor lets it play well with fillings or frostings.
- Leftovers? Please.: I make this on a Sunday, and by Wednesday, I’m still sneaking bites. The cake stays fresh for days (yes, even without frosting) because the cornstarch and butter combo locks in moisture. Plus, it’s budget-friendly—you’re using pantry staples, not specialty ingredients. My kids beg for the scraps, and I’ll admit, I’ve been known to eat them first.
Step-by-step instructions for towering vanilla cake
Mastering this method delivers a flawlessly structured cake perfect for fondant covering.
Prepare Dry Ingredients with Precision
In a large mixing bowl, combine the 3 cups All-Purpose Flour, 1 cup Cake Flour, 2 tbsp Cornstarch, 2 tsp Baking Powder, and 0.5 tsp Salt. Sift all ingredients together twice through a fine-mesh sieve to eliminate any lumps and aerate the mixture. This step is critical—it prevents dense patches in your cake and ensures a light, even crumb.
Use a whisk to gently combine the dry ingredients until uniformly distributed. Set aside the bowl, keeping it covered with a clean kitchen towel to prevent any moisture absorption from the air. I’ve found that pre-sifting saves time later and guarantees a smoother batter. The cake flour in particular needs this extra attention to maintain its delicate texture.
Cream Butter and Sugar to Peak Volume
In a stand mixer fitted with the paddle attachment, beat the 1 lb Unsalted Butter (cut into 1-inch cubes and brought to room temperature) with the 2 cups Granulated Sugar on medium speed for 5-7 minutes. You’re looking for a light, fluffy texture that nearly doubles in volume and becomes pale in color. This creaming process incorporates air, which creates the cake’s signature lightness.
I press down on the butter mixture occasionally during the first 2 minutes to help break down any remaining lumps. Stop beating when the mixture looks like ribbon when the paddle is lifted—this indicates proper aeration. The butter should be completely smooth with no visible graininess. If you rush this step, your cake will be dense rather than tender.
Incorporate Wet Ingredients Gradually
Add the 4 whole Large Eggs, one at a time, mixing on low speed after each addition until fully incorporated. Then add the 2 tbsp Vanilla Extract and mix for 30 seconds. Scrape down the sides of the bowl with a rubber spatula to ensure all ingredients are properly combined. The mixture should be thick but pourable.
Next, alternate adding the 1 cup Whole Milk and the prepared dry ingredients in three additions. Begin and end with the dry ingredients, mixing on low speed after each addition just until combined. Overmixing develops gluten, which leads to a tough cake. The batter should be smooth with no visible streaks of flour. At this stage, it should be thick but still able to be piped smoothly.
Divide and Bake for Perfect Structure
Preheat your oven to 350°F and grease three 9-inch round cake pans with vegetable oil, then line the bottoms with parchment paper. Divide the batter evenly among the prepared pans. Tap each pan firmly on the counter twice to remove any air bubbles. Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean.
I’ve found that rotating the pans halfway through baking ensures even browning. The cakes should be golden on top with slightly domed centers. Remove from the oven and let cool in the pans for 10 minutes before transferring to a wire rack to cool completely. Cooling gradually prevents cracking and maintains the cake’s structure for fondant application.
Level and Prepare for Fondant
Once completely cool, use a serrated knife to carefully level the tops of the cakes, creating smooth, even surfaces. Place the first cake on a cake board, apply a thin layer of buttercream, and place the second cake on top. Repeat with the third cake. Chill the stacked cake in the refrigerator for 30 minutes to firm up before applying fondant.
This chilling step is essential for preventing the fondant from sliding off during application. The cakes should be completely cool and stable before any fondant work begins. The buttercream layer should be thin but even to create a perfect foundation for your fondant crown.
Pro Tips For Making 1kg Vanilla Cake
- Weigh Your Flours Precisely: Sifting cake flour and cornstarch is tempting, but for a 1kg vanilla cake, use a kitchen scale to measure all dry ingredients—especially the cake flour. I learned this after a batch turned dense; the tiniest extra gram of flour changes the texture. Spoon-and-level isn’t enough here.
- Cream Butter and Sugar Slowly: Dump the butter and sugar into your mixer at once? Bad move. For this recipe, add the butter in 3-4 additions while mixing on medium—it emulsifies better and prevents greasy layers. My grandmother’s trick: let the mixer run for 30 seconds between additions.
- Don’t Overmix the Batter: Once you fold in the eggs and vanilla, stop mixing the second everything’s just combined. Overworking the batter introduces too much air, leading to a cake that collapses or has tunnels. I used to think more mixing = fluffier result—wrong.
- Use Room-Temp Butter: Cold butter creates pockets that don’t dissolve, leaving your cake dry. Take the butter out of the fridge 1-2 hours before starting (or microwave it in 10-second bursts until soft). This isn’t the prettiest method, but it’s the thing that matters most for a moist crumb.
Best sauces and condiments for these flavors
Classic Vanilla Buttercream
This is my go-to sauce for this vanilla cake—smooth, rich, and perfectly balanced. Whip 1 lb unsalted butter (room temperature) with 4 cups powdered sugar and ¼ cup heavy cream until light and fluffy. Add 1 tsp vanilla extract and 1 tbsp milk to adjust consistency. Spread between cake layers and on top for a professional finish. 🍰
Citrus Curd Glaze
Brighten up your cake with a tangy citrus glaze that cuts through the richness. Mix ½ cup lemon juice, ½ cup orange juice, ¼ cup sugar, and 2 tbsp cornstarch in a saucepan. Cook over medium heat until thickened, then strain and drizzle over cooled cake layers. The acidity enhances the vanilla flavor beautifully.
Salted Caramel Sauce
For a decadent touch, warm 1 cup heavy cream with 1 cup granulated sugar until dissolved, then simmer until it turns a golden amber color. Whisk in ¼ cup butter and 1 tsp flaky sea salt. Drizzle over the cake or use as a filling between layers. The salt amplifies the cake’s sweetness perfectly.
Chocolate Ganache
Melt ½ cup dark chocolate chips with ½ cup heavy cream in a double boiler, then let it cool slightly before pouring over the cake. For extra flair, add 1 tbsp espresso powder to the chocolate for a mocha twist. This pairs wonderfully with vanilla cake and adds a sophisticated contrast. 🍫
Fruit Compote Topping
Simmer 2 cups mixed berries (strawberries, blueberries, raspberries) with 2 tbsp sugar and 1 tsp lemon juice until thickened. Cool and spread over the cake layers or use as a decorative topping. The natural sweetness and acidity complement the vanilla beautifully while adding freshness.
Cream Cheese Frosting
Beat 8 oz cream cheese, ½ cup butter, and 3 cups powdered sugar until smooth, then add 1 tsp vanilla extract. This lighter frosting is perfect for those who prefer a less rich topping. It spreads easily and pairs wonderfully with the cake’s tender crumb. Add a sprinkle of toasted coconut flakes for texture. 🥥

Frequently asked questions
Can I make this vanilla cake in a different pan size?
Yes, but adjust the baking time and temperature. For 8-inch pans, bake at 350°F for 30-35 minutes—the smaller surface area means slightly longer baking. For 10-inch pans, reduce to 325°F and bake for 20-25 minutes to prevent over-browning. Always use a toothpick test to check doneness.
Why does my cake sink in the middle?
This usually happens from overmixing the batter (developing gluten) or opening the oven too soon. For this recipe, mix dry ingredients just until combined, and avoid peaking at the cakes until the 25-minute mark. Also ensure your oven is fully preheated—temperature fluctuations cause uneven rising.
Can I substitute cake flour with all-purpose flour?
Yes, but reduce the all-purpose flour by 2 tbsp and add 2 tbsp cornstarch to each cup of all-purpose flour used. This mimics cake flour’s protein content. For example, use 2 cups + 4 tbsp all-purpose flour plus 4 tbsp cornstarch instead of the 1 cup cake flour in the recipe.
How do I store leftover cake?
Wrap tightly in plastic wrap or place in an airtight container at room temperature for up to 3 days. For longer storage, freeze slices wrapped individually for up to 3 months. Thaw overnight in the fridge before serving. The cake’s structure holds up well to freezing, but avoid refrigerating for more than 5 days to prevent drying.
What’s the best way to level the cakes?
Use a serrated knife and a leveling guide (like a ruler or cake leveler). Dip the knife in hot water, wipe dry, and press firmly at a 45-degree angle while moving in a gentle sawing motion. Work in small sections to avoid crumbling. This ensures smooth, even surfaces for fondant application or stacking.
