Ingredients for 100 gram cake
Precision portions start with these exact measurements—no guesswork, just perfect bite-sized cake every time.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 0.08 cup | Sifted for light texture |
| Unsalted Butter 🧈 | 0.05 cup | Cold, cubed for precision |
| Granulated Sugar 🍚 | 0.05 cup | Superfine preferred for smoothness |
| Large Eggs 🥚 | ⅛ whole | Room temperature for blending |
| Vanilla Extract 🌸 | ½ tsp | Pure, high-quality extract |
| Baking Powder 🍞 | 0.06 tsp | Freshly opened for lift |
| Salt 🧂 | 0.03 tsp | Fine sea salt preferred |
| Milk 🥛 | 0.03 cup | Whole milk for richness |
| Parchment Paper 📄 | 1 sheet | For perfect release |
| Powdered Sugar 🍚 | 0.03 cup | Optional for dusting |
The flour and butter ratio here is non-negotiable for that tender crumb. King Arthur or Gold Medal flours work best—they're finely milled and consistent. For the butter, Plugrá or Land O'Lakes unsalted sticks are my go-tos, but any brand works if it's cold and cubed. Room-temperature eggs blend smoothly, but don't overbeat them—just until combined. The vanilla extract should be pure, not imitation. McCormick or Nielsen-Massey are reliable brands. Baking powder needs to be fresh—if it's more than six months old, toss it and start fresh.
No vanilla extract? Almond extract at half the amount works in a pinch, but it has a distinct flavor. Short on milk? Heavy cream or half-and-half adds richness, but you'll need to reduce the sugar slightly. For a chocolate version, swap half the flour for Dutch-process cocoa powder and add 0.025 cup extra sugar. The powdered sugar is optional but gives that professional finish—Domino or Confectioners' Sugar brands are finely ground and ideal. If you're scaling up, multiply these amounts by 4 for a standard 9-inch cake.
Store the dry ingredients—flour, baking powder, and powdered sugar—in airtight containers in a cool, dark place for up to 6 months. Butter keeps for 3 months in the fridge, wrapped tightly. Once mixed, the batter can sit at room temperature for 1 hour before baking—just cover it to prevent drying. The finished cake stays fresh for 3 days at room temperature or 1 week refrigerated, wrapped tightly. For longer storage, freeze portions for up to 3 months

Step-by-step instructions for precision portioned cake
Here's how to craft a flawless single-serving cake with exact measurements every time.
Prep Ingredients for Perfect Texture
Start by sifting the 0.075 cup all-purpose flour and 0.0625 tsp baking powder together in a small bowl. This removes lumps and ensures a light, airy crumb. In another bowl, measure out the 0.05 cup granulated sugar and 0.03125 tsp salt - the sugar will help create that tender crumb structure while the salt balances sweetness.
Cut the 0.05 cup unsalted butter into small cubes and let it sit at room temperature for 10 minutes until just soft but still holds its shape. This cold-but-not-frozen state is crucial for creating a tender cake rather than a dense one. The eggs should be at room temperature too - I like to separate them first and let the whites sit in their own bowl while I work with the yolks.
Cream Butter and Sugar for Maximum Lightness
In a stand mixer fitted with the paddle attachment, beat the butter and sugar on medium speed for 3-4 minutes until the mixture is light and fluffy, nearly doubling in volume. You'll see the color lighten and the texture become almost mousse-like. This step incorporates air which creates that signature tender crumb in our perfect single serving.
Add the 0.125 whole large egg yolks one at a time, mixing well after each addition. Then stir in the 0.5 tsp vanilla extract and 0.025 cup milk. The mixture should be smooth and slightly thick. I always scrape down the sides of the bowl at this point to ensure everything is properly incorporated - no flour pockets allowed in our precision cake!
Combine Dry and Wet Ingredients Gently
With the mixer on low speed, gradually add the sifted flour mixture to the wet ingredients. Mix just until combined - you should still see some streaks of flour. Overmixing develops gluten which would make our delicate cake tough. The batter should be smooth and slightly thick, similar to heavy pudding.
In a separate bowl, whip the 0.125 whole large egg whites to stiff peaks using a hand mixer. This will add extra lightness to our cake. Fold about one-third of the whipped egg whites into the cake batter to lighten it, then gently fold in the remaining egg whites using a spatula in a figure-eight motion. This keeps all the air incorporated without deflating the structure.
Bake to Golden Perfection
Preheat your oven to 350°F and line a mini cake pan or small ramequin with the parchment paper, pressing it into the corners to prevent sticking. Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 20-25 minutes until a toothpick inserted into the center comes out clean and the top springs back when touched.
The cake should have a golden dome shape with slightly crisp edges. Real talk - don't open the oven door during baking or you'll risk a cake that falls in the middle. When done, remove from the oven and let cool in the pan for 5 minutes, then transfer to a wire rack to cool completely. Dust with 0.025 cup powdered sugar if desired for that final touch of elegance.
Pro Tips For Making 100 Gram Cake
- MEASURE BUTTER COLD: Take that unsalted butter straight from the fridge—no softening, no room-temperature nonsense. I learned this the hard way with a greasy, dense cake that looked like it was made with lard. Cold butter creates pockets for air, giving you that light, fluffy texture you actually want.
- WHISK EGGS ROOM TEMP: Let those eggs sit in warm water for 5 minutes before cracking them—yes, even if you’re impatient. Cold eggs mix unevenly and can make your batter lumpy, and nobody wants a cake with the texture of a sponge that’s seen better days. Trust me, the extra minute saves you from re-whisking.
- STOP WHEN SPRINGY: The second your cake pulls away from the pan edges but still jiggles slightly in the center, it’s done. I used to overbake because I thought "fully set" meant "dry as a bone," but that’s how you end up with a brick. A toothpick test is fine, but your finger knows better—press it gently, and if it springs back, you’re golden.
- SIFT THE FLOUR FIRST: Dump that all-purpose flour straight into the bowl, and you’re asking for lumps and uneven texture. Sift it first—even if you’re not a fancy baker—so the sugar and butter can blend smoothly. I skip this when I’m lazy, and the cake turns out noticeably denser. Not worth the effort? Do it anyway.
Storing and reheating this dish
Room-Temp Storage
Your freshly baked 100-gram cake stays fresh for 3 days at room temperature when stored in an airtight container with a piece of parchment paper between layers. I like using Rubbermaid Brilliance containers because they seal tightly and don't let air in. The key is to let it cool completely first—never store warm cake or it'll develop condensation and become soggy. For extra protection, add a damp paper towel on top before sealing. 🌟
Fridge Preservation
Extend freshness to 1 week by refrigerating your cake in the same airtight container. The cold temperature slows moisture loss and keeps the texture perfect. I wrap mine in plastic wrap first, then place it in the container to create a double barrier. When ready to serve, let it sit at room temperature for 10-15 minutes to soften slightly—this makes it more enjoyable to eat straight from the fridge. 🥶
Freezer Magic
For long-term storage, freeze your cake for up to 3 months using quart-sized freezer bags or airtight containers. Wrap each portion tightly in plastic wrap first to prevent freezer burn. Thaw overnight in the fridge—never at room temperature—or microwave for 10-15 seconds on 50% power for quick serving. The texture remains surprisingly moist after freezing, thanks to the precise butter-to-flour ratio. ❄️
Reheating Secrets
For the best texture, reheat your cake in a 350°F oven for 5-8 minutes wrapped in foil. This gently warms it without drying out the edges. If using a microwave, heat for 10-15 seconds on 50% power—any longer and you'll risk rubbery texture. My pro tip: Add a dab of milk or water to a paper towel before microwaving to keep it moist. 🔥
Make-Ahead Tips
Prepare the batter up to 1 day ahead and store it in the fridge. When ready to bake, let it sit at room temperature for 30 minutes before mixing—this ensures even baking. For a dessert buffet, bake all portions in advance and store them separately. Reheat just before serving so they're warm and delicious. This method saves time and guarantees perfect results every time. ✨
Portion Control
Since each cake is exactly 100 grams, it makes perfect single servings. Store individual portions in small containers or wrap them in parchment paper. This way, you can grab just what you need without dealing with leftovers. The precise portioning also makes it ideal for meal prep—just bake a batch and store them for quick treats throughout the week. 💡

Frequently asked questions
Can I use this recipe for a larger cake?
Multiply all ingredients by 4 to make a standard 9-inch cake (about 1 pound total). For a 6-inch cake, multiply by 2.5. Just ensure your pan is the right size and preheat the oven to 350°F for consistent baking. The same ratio of butter to flour keeps the texture perfect.
Why does my cake sink in the middle?
This usually happens from opening the oven door too early or underbaking. Let the cake bake undisturbed for the full 20-25 minutes, and check doneness with a toothpick—it should come out clean. Also, ensure your oven isn't too hot; 350°F is critical for this recipe. A damp paper towel on the rack below the pan can help create steam for a better rise.
Can I substitute butter with oil?
Not recommended! Butter creates the signature tender crumb and flavor in this recipe. If you must substitute, use 1/4 cup melted butter-flavored shortening (like Crisco) for the same fat content. Oil would make the cake denser and alter the texture. The cold, cubed butter is key for that perfect lightness.
How do I make this recipe gluten-free?
Replace the all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill or King Arthur). You may need to add 1/4 tsp xanthan gum to improve structure. Reduce the milk by 1 tablespoon since gluten-free flours absorb more liquid. Test the batter consistency—it should be slightly thicker than the original.
What's the best way to decorate this mini cake?
Keep it simple with a dusting of powdered sugar or a drizzle of melted chocolate. For a pop of color, add fresh berries or a sprinkle of edible glitter. Since it's only 100 grams, avoid heavy toppings that could weigh it down. A thin layer of whipped cream also pairs beautifully with the rich flavor.
