Ingredients for 1 kg cake
Precision meets perfection in this 1 kg cake—where science and artistry balance for restaurant-quality results.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 3 ½ cups | Sifted for light texture |
| Granulated Sugar 🍚 | 2 cups | White or light brown |
| Unsalted Butter 🧈 | 1 ½ cups | Room temperature, cubed |
| Vegetable Oil 🫒 | ½ cup | Light, neutral flavor |
| Large Eggs 🥚 | 6 whole | Room temperature |
| Plain Yogurt 🍶 | ½ cup | Full-fat preferred |
| Baking Powder 🌶️ | 2 tsp | Aluminum-free preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vanilla Extract 🌿 | 2 tsp | Pure vanilla preferred |
| Milk 🥛 | ½ cup | Whole milk for richness |
| Cornstarch 🌾 | 1 tbsp | For moisture retention |
The butter-to-oil ratio is critical here. European-style unsalted butter (like Plugrá or President) melts more evenly than American brands, creating a smoother crumb. If you can't find it, Land O'Lakes or Kerrygold work well too—just ensure it's room temperature. The vegetable oil adds moisture without heaviness, so don't skimp. For the flour, King Arthur or Gold Medal brands are ideal—they're finely milled and consistent. If your kitchen isn't humid, add an extra tablespoon of milk to prevent dryness. The yogurt acts as a natural tenderizer, so full-fat Greek yogurt gives the best texture.
No vanilla extract? Vanilla bean paste or even vanilla sugar works in a pinch—just reduce sugar slightly. Short on eggs? Flax eggs (1 tbsp ground flaxseed + 3 tbsp water per egg) maintain structure, though texture will differ. For a gluten-free version, swap flour for a 1:1 gluten-free baking blend—add an extra teaspoon of baking powder. The baking powder must be fresh; if it's over a year old, test it in a small bowl with water—it should bubble vigorously. If not, double the amount. For a richer flavor, replace half the milk with heavy cream.
Store this cake in an airtight container at room temperature for up to 5 days—it actually improves as it sits. For longer storage, wrap tightly in plastic and refrigerate for up to 2 weeks. To revive, let it sit at room temperature for 30 minutes before slicing. Freeze for up to 3 months by wrapping each slice individually in plastic wrap. The cake reheats beautifully—wrap a slice in foil and warm in a 200°F (95°C) oven for 5 minutes to restore moisture. The whipped egg whites in the final step are non-negotiable for that domed top and tender crumb.

Step-by-step instructions for 1 kilo cake recipe
This method guarantees a perfectly balanced cake—tender crumb, reliable height, and moisture that lasts.
Prepare Ingredients for Optimal Texture
Begin by sifting the 3.5 cups all-purpose flour and 2 tsp baking powder together into a medium bowl. This removes lumps and ensures an even distribution of leavening, which is critical for consistent rise. Set aside while you prepare the wet ingredients.
In a separate large bowl, whisk together the 2 cups granulated sugar, 0.5 cup vegetable oil, and 2 tsp vanilla extract until fully combined. The sugar should dissolve completely, creating a smooth base. This step prevents graininess in the final batter.
Combine Wet Ingredients for Lightness
Add the 6 whole large eggs to the sugar mixture one at a time, whisking vigorously after each addition. This gradual incorporation prevents the eggs from curdling, which would create a dense cake. The mixture should thicken slightly but remain smooth and pale.
Next, incorporate the 1.5 cups unsalted butter (cut into small cubes) into the wet mixture. Use a hand mixer on medium speed until fully combined and the butter is completely melted. The batter should look like a thick, creamy custard—this ensures proper fat distribution for moisture retention.
Fold in Dry Ingredients Gently
Gradually add the sifted flour mixture to the wet ingredients in three additions, mixing on low speed just until combined after each. Overmixing develops gluten, which leads to a tough cake. The batter should be smooth with a ribbon-like consistency when the whisk is lifted.
Stir in the 0.5 cup plain yogurt, 0.5 cup milk, and 1 tbsp cornstarch by hand using a spatula. Fold gently to maintain air pockets created during mixing. The cornstarch helps retain moisture, while the yogurt adds tenderness and slight tanginess.
Bake with Precision for Even Rise
Preheat your oven to 350°F and grease two 9-inch round cake pans thoroughly. Line the bottoms with parchment paper for easy removal. Divide the batter evenly between the pans, smoothing the tops with a spatula.
Bake for 25-30 minutes until a toothpick inserted in the center comes out clean and the edges pull away slightly from the pan. Rotate the pans halfway through baking to ensure even heat distribution. The cake should spring back gently when pressed—this confirms proper doneness.
Cool and Layer for Perfect Moisture
Remove the cakes from the oven and let them cool in the pans for 10 minutes. Then transfer them to a wire rack to cool completely. This gradual cooling prevents cracking and allows the internal structure to set properly.
Once fully cooled, level the tops if needed and prepare your filling (if using). For maximum moisture, brush the layers with a simple syrup made from equal parts sugar and water, heated until dissolved. This step ensures your cake stays tender for days.
Pro Tips For Making 1 Kg Cake
- WEIGH THE BUTTER COLD: I learned this the hard way—room-temperature butter makes a dense, greasy cake. Stick 250g unsalted butter in the fridge for 30 minutes before creaming. You want it soft enough to press with a finger but not oily; this ensures light layers and proper rise.
- WHISK EGGS UNTIL TRIPLE VOLUME: Don’t just mix the eggs—beat them until they’re pale, thick, and ribbon-like. For 6 large eggs, this takes about 3 minutes with a stand mixer. Skimp here, and your cake will sink like a stone; push it, and you’ll get that cloud-like texture.
- SIFT FLOUR IN THIRDS: Dumping flour all at once develops gluten and makes the cake tough. Sift it in three additions while mixing on low, alternating with the liquid. This keeps the crumb tender—trust me, your fork will thank you.
- BAKE WITH A WATER BATH: Yes, even for a 1 kg cake. Wrap the pan in foil, place it in a roasting tin, and add 2 cm of hot water before baking. This locks in moisture and prevents cracking, especially if your kitchen runs hot. (I know, it’s extra work—but your slice will be worth it.)
Make-ahead tips for this dish
Prep Ahead Strategy
Bake the cake layers 24 hours ahead and store them in an airtight container at room temperature. The flavors deepen as the cake sits, and the moisture is preserved better than fresh-baked layers. I always bake mine the night before—it’s a game-changer for busy mornings. Just wrap each layer tightly in plastic wrap before storing. 💫
Filling and Assembly
Prepare your filling (like buttercream or jam) the day before and store it in the refrigerator. Chill the filling for at least 2 hours before assembling to make layering easier. I like using Swiss meringue buttercream because it stays stable in warm kitchens. Assemble the cake 4-6 hours before serving to allow the filling to set properly.
Frosting Techniques
For a flawless finish, frost the cake 2 hours before serving to give the frosting time to settle. If using a crumb coat, apply it 1 hour after assembly—this prevents crumbs from mixing into your final layer. I recommend using a piping bag with a star tip for a smooth finish. Let the frosting sit at room temperature for 30 minutes before adding final decorations.
Storage Hacks
Store the fully assembled cake in the refrigerator for up to 5 days—just bring it to room temperature for 1 hour before serving. For longer storage, freeze the cake (unfrosted) for up to 3 months. Wrap each layer individually in plastic wrap and aluminum foil to prevent freezer burn. Thaw overnight in the fridge before frosting and decorating.
Reheating Slices
Revive stale slices by wrapping them in a damp paper towel and microwaving for 10-15 seconds. For a warmer touch, place slices in a 250°F (120°C) oven for 3-5 minutes. The moisture from the towel or oven restores the cake’s softness. This trick works especially well for cakes stored for 3-4 days.

Frequently asked questions
Can I make this 1 kg cake recipe in a different pan size?
Yes! This recipe works perfectly in 9-inch round pans (for 2 layers) or a 9x13-inch sheet pan (for a single layer). For a 9x13-inch pan, bake at 350°F (175°C) for 35-40 minutes until a toothpick comes out clean. For bundt cakes, use a 10-12 cup capacity pan and reduce baking time by 5-10 minutes—the center will take longer to cook.
Why does my cake sink in the middle even with this recipe?
This usually happens from overmixing the batter or opening the oven door too soon. Mix only until combined (no streaks of flour) and avoid overfilling pans—fill them 2/3 full max. For extra stability, bake at 325°F (160°C) instead of 350°F—the slower heat helps set the structure before the center rises. Let the cake cool 10 minutes in the pan before removing.
How can I make this cake gluten-free?
Replace the all-purpose flour with a 1:1 gluten-free baking blend (like Bob's Red Mill or King Arthur) and add 1 extra teaspoon of baking powder. For moisture, increase the yogurt to 0.75 cup and add 1 tablespoon of xanthan gum if your blend doesn't include it. Gluten-free cakes often need 5-10 extra minutes in the oven—check doneness with a toothpick.
Can I substitute butter with oil for a lighter cake?
You can replace half the butter (0.75 cup) with oil, but keep 0.75 cup butter for flavor and structure. Oil makes the cake slightly denser but keeps it moist longer. For a truly light texture, use 100% oil and reduce sugar by 0.25 cup—this balances the richness. The cake will have a finer crumb but may not rise as high as the butter version.
How do I prevent cracks on the top of my cake?
Cracks form from rapid cooling or uneven baking. To avoid them, bake at 325°F (160°C) instead of 350°F for the first 15 minutes, then increase to 350°F (175°C). After baking, let the cake cool 10 minutes in the pan before removing. For extra insurance, brush the top with simple syrup (equal parts sugar and water) while warm—this helps seal the surface.
