Ingredients for 1 kg cake recipe in cups
Precision-baked ingredients for a foolproof 1 kg cake with perfectly level layers every time.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 4 ½ cups | Sifted for lightness, plus extra for dusting |
| Granulated Sugar 🍚 | 2 ½ cups | Superfine preferred for smooth texture |
| Unsalted Butter 🧈 | 2 ¼ cups | Room temperature, full-fat for richness |
| Large Eggs 🥚 | 6 whole | Room temperature for even mixing |
| Vanilla Extract 🌿 | 2 tsp | Pure, high-quality vanilla preferred |
| Baking Powder 🍳 | 2 ½ tsp | Freshly measured for proper rise |
| Salt 🧂 | ¾ tsp | Fine sea salt for balanced flavor |
| Whole Milk 🥛 | 1 ½ cups | Room temperature for smooth batter |
| Cornstarch 🌽 | 1 ½ tbsp | For tender crumb and level bake |
| Cream of Tartar 🍋 | ½ tsp | Stabilizes egg whites if needed |
| Vegetable Oil 🫒 | ½ cup | Lightens texture and extends shelf life |
| Almond Extract 🌿 | ½ tsp | Optional, for subtle depth (omit for vanilla) |
| Cake Release Agent 🧴 | 1 tbsp | Or vegetable oil for greasing pans |
The flour is non-negotiable here—King Arthur or Gold Medal brands are my go-to for that tender crumb. Superfine sugar dissolves faster, but if you only have granulated, pulse it in a food processor for 30 seconds. Butter is the backbone: Plugrá or Land O'Lakes unsalted melt smoothly, but don't substitute margarine—it won't give the same structure. Eggs should be at room temp (pop them in warm water for 10 mins if they're cold), and free-range or organic adds subtle richness. For vanilla, Heinz or Nielsen-Massey pure extract—the imitation stuff ruins everything. Pro tip: measure your baking powder and salt together to avoid cross-contamination.
No almond extract? Skip it—vanilla alone works perfectly. Short on cornstarch? Arrowroot powder at 1:1 ratio is a decent swap, but the texture won't be identical. The vegetable oil can be swapped for melted butter (reduce other butter by 0.25 cup), but it'll make the cake denser. For a gluten-free version, use a 1:1 GF flour blend and add 0.5 tsp xanthan gum. The milk? Any kind works—just make sure it's room temp. And if you're baking in high altitude, reduce baking powder by 0.5 tsp to prevent dome-shaped cakes. Trust me, the cornstarch is worth hunting down—it's what keeps this cake from being gummy.
This batter keeps for 2 days in the fridge, covered tightly. For longer storage, portion into ziplock bags and freeze for up to 3 months. Thaw overnight in the fridge before baking. Pans? 9x2-inch rounds or 8x8-inch square work best—grease with oil and dust with flour (or use a silicone mat). Cool layers completely on a wire rack before stacking. And here's the secret to level layers: bake until a toothpick comes out with moist crumbs, not wet batter. Overbaking is the #1 reason cakes crack.
Why You'll Love This Recipe

Step-by-step instructions for precision baked layer cake
Here's how to bake a flawless, perfectly level cake that weighs exactly 1 kg.
Prepare Pans and Prep Ingredients for Precision
Grease three 9-inch round cake pans with the 1 tablespoon cake release agent, then dust with ½ cup of the 4.5 cups all-purpose flour set aside for this purpose. Tap out any excess flour to ensure a clean release later. Line the bottoms with parchment circles for easy removal and even baking.
Place the 2.25 cups unsalted butter in a large mixing bowl and let it sit at room temperature for 30 minutes until it's soft but not melted—you should be able to press your finger into it and leave a slight indent. Meanwhile, sift the remaining 4 cups all-purpose flour with the 2.5 teaspoons baking powder and 0.75 teaspoon salt into a separate bowl. This step prevents lumps and ensures an even texture throughout the cake.
Cream Butter and Sugar to Light and Fluffy
Using a stand mixer fitted with the paddle attachment, beat the 2.25 cups unsalted butter on medium speed for 2 minutes until completely smooth. Gradually add the 2.5 cups granulated sugar, mixing on medium-high speed for 4-5 minutes until the mixture is light, fluffy, and nearly tripled in volume. You'll see ribbons form when you lift the beaters—this is your signal that air has been properly incorporated.
Real talk: This step makes or breaks the cake's texture. If you rush it, your cake will be dense. Scrape down the sides of the bowl with a spatula every minute to ensure even mixing. The butter should be pale in color by the end, with no visible streaks of sugar.
Incorporate Wet Ingredients for Perfect Moisture Balance
Add the 6 whole large eggs, one at a time, mixing on low speed after each addition until fully incorporated. Then add the 2 teaspoons vanilla extract, 0.5 teaspoon almond extract (if using), 1.5 cups whole milk, and 0.5 cup vegetable oil. Mix on medium speed for 1-2 minutes until completely combined and smooth.
Next, alternate adding the sifted dry ingredients in three additions with 1.5 tablespoons cornstarch mixed into ½ cup of the batter first. Start and end with the dry ingredients to prevent overmixing. Mix on low speed just until combined—you should still see small streaks of flour. Overmixing develops gluten, which leads to a tough cake.
Divide and Bake for Perfectly Level Layers
Divide the batter evenly among the prepared pans, tapping each pan gently on the counter to remove any air bubbles. Place the pans in a preheated 350°F oven and bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Rotate the pans halfway through baking for even browning.
Don't open the oven during baking—this causes the cakes to sink. Instead, trust the toothpick test. When done, remove the pans and let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely. This gradual cooling prevents cracking and ensures clean release from the pans.
Level and Assemble with Confidence
Once completely cool, place each cake on a level surface and use a long serrated knife to trim the domed tops to create perfectly flat layers. Place a plate on top of the cake and press down firmly to create a level surface. Repeat this process for all three layers.
To assemble, place the first layer on a cake stand or plate. Spread a thin layer of your favorite filling (like buttercream or jam) evenly over the top, then repeat with the remaining layers. The key here is to keep everything level—use a cake leveler or the back of a long knife to check as you go. Chill the assembled cake in the refrigerator for 30 minutes before serving to help it hold its shape.
Pro Tips For Making 1 Kg Cake Recipe In Cups
- Weigh Your Butter: I learned this the hard way—packing butter into measuring cups leaves air pockets, and your cake will end up denser than a brick. Use a kitchen scale for 225g (1 cup) of unsalted butter; scoop it straight from the fridge and press it down firmly. No guesswork, no sad crumb structure.
- Whip Eggs at Room Temp: Cold eggs from the fridge won’t incorporate properly, and you’ll end up with a cake that’s more like a sad, flat pancake. Let your eggs sit in warm water for 10 minutes before whipping—just enough to loosen the yolks. Trust me, the difference in rise is noticeable.
- Don’t Overmix the Batter: I used to think more mixing = better cake. Wrong. Once you fold in the flour, stop when it’s just combined—lumps are fine. Overmixing develops gluten, and your cake will turn out tough instead of tender. Two minutes max after adding dry ingredients.
- Bake Until Springy: Your cake isn’t done when the top looks set—it’s done when the center springs back slowly when gently pressed. If you pull it out too soon, it’ll collapse like a deflating balloon. Insert a toothpick: it should come out with moist crumbs, not wet batter. Patience here saves you from a gummy mess.
Dietary considerations for this recipe
Gluten-Free Adaptation
For a gluten-free version, replace the 4.5 cups all-purpose flour with 4.5 cups gluten-free 1:1 baking flour blend (like Bob’s Red Mill or King Arthur). Add 0.5 teaspoon xanthan gum to mimic gluten’s structure—this prevents crumbling. Use superfine sugar and cornstarch as listed, but sift the GF flour extra well to avoid lumps. I’ve tested this with King Arthur GF flour and achieved a tender crumb, though the texture is slightly denser than traditional cake. 🌾
Dairy-Free Options
Swap 2.25 cups unsalted butter for 2.25 cups dairy-free butter (like Miyoko’s or Earth Balance) or 2 cups coconut oil (melted and cooled). Replace 1.5 cups whole milk with 1.5 cups unsweetened almond milk or oat milk—just ensure it’s room temperature. For richness, add 0.25 cup coconut cream to the wet ingredients. The cake stays moist but may have a subtly different flavor profile. 🥛
Egg-Free Substitution
To make this egg-free, replace the 6 eggs with a flax egg mixture: 6 tablespoons ground flaxseed + 1.5 cups water, mixed and rested for 10 minutes to thicken. For extra lift, add 1 teaspoon apple cider vinegar to the wet ingredients. The texture will be slightly denser but still light. I’ve found this works best when combined with 1 extra tablespoon baking powder to compensate for lost structure. 🥚
Nut-Free Considerations
Skip the 0.5 teaspoon almond extract and 0.5 cup vegetable oil (if concerned about nut cross-contamination). Replace the oil with 0.5 cup melted coconut oil (nut-free) or avocado oil. For flavor depth, add 0.5 teaspoon orange zest or an extra 0.5 teaspoon vanilla extract. The cake remains tender and flavorful without nuts. Always check labels on extracts and oils for hidden nut traces. 🍊
Lower-Sugar Adjustments
Reduce 2.5 cups granulated sugar to 1.75 cups and replace the remaining 0.75 cup with 0.5 cup honey or 0.5 cup maple syrup. Add 1 teaspoon cream of tartar to stabilize the batter. The cake will be slightly denser but still moist. For extra sweetness, brush layers with simple syrup (equal parts sugar and water, heated until dissolved) before assembling. 🍯
Allergen-Friendly Tips
For soy-free baking, ensure your vanilla extract and baking powder are soy-free (some brands contain soy lecithin). For corn-free, replace 1.5 tablespoons cornstarch with 1.5 tablespoons arrowroot powder. Always double-check labels—hidden allergens can sneak into extracts and oils. Cross-contamination is key: use separate utensils and bowls for allergen-free prep. ✨

Frequently asked questions
Why does this recipe use cups instead of grams?
This recipe converts to cups for American home bakers who may not have a kitchen scale. The measurements are precision-tested to ensure a 1 kg yield while maintaining the perfect texture. For example, 4.5 cups flour equals exactly 560 grams—no guessing! If you prefer grams, we’ve included the exact conversions in the ingredient notes.
How do I adjust this for a smaller or larger cake?
For a smaller cake, reduce all ingredients by 25% (e.g., 3.4 cups flour for a 750g cake). For a larger cake, increase by 25% (e.g., 5.6 cups flour for a 1.25 kg cake). Always keep the ratio of wet to dry ingredients the same—this ensures the same rise and texture. Pro tip: Use a kitchen scale for accuracy if scaling up.
Can I bake this in a different pan size?
Yes! For 8-inch pans, reduce batter by 33% per pan (use 1.5 cups batter per 8-inch pan). For 10-inch pans, increase by 33% (use 2 cups batter per 10-inch pan). The key is to maintain the same batter depth (2 inches) for even baking. Adjust oven time by ±5 minutes based on pan size—smaller pans bake faster.
Why did my cake sink in the middle?
This usually happens from overmixing (developing gluten) or opening the oven too soon. To fix it: Whip the batter gently until just combined, and avoid peeking during baking. For next time, check oven temperature with an oven thermometer—many run 25°F hotter than set. Also, ensure your leavening agents (baking powder) are fresh. A sunken cake can often be saved with a quick buttercream frosting!
How do I store or freeze leftover cake?
Store at room temperature in an airtight container for up to 3 days. For longer storage, wrap each layer tightly in plastic wrap, then place in a freezer bag. Frozen layers keep for 3 months. Thaw overnight in the fridge before assembling. To refresh texture, brush with simple syrup (equal parts sugar and water) before serving.
