Ingredients for 100 gram cake

Five core ingredients plus two optional variations—this is your precision cake toolkit.

The flour is your foundation—King Arthur or Gold Medal brands work best for that tender crumb. If you're making multiple cakes, sift the flour first to avoid dense results. Butter matters too—European-style melts cleaner, but Plugrá is perfect for beginners. Room temperature is key: press a thumb into the butter, and if it leaves a slight indent, it's ready. For the eggs, separate yolks and whites if you want to fold them in later for extra fluffiness. The vanilla extract should smell potent—McCormick Pure is my go-to, but any pure extract works.

No vanilla? Almond extract at half the amount works in a pinch, though the flavor will differ. Dutch-processed cocoa gives that smooth, rich chocolate flavor—Hershey's Special Dark is a solid budget option. For matcha, Ippodo Tea ceremonial grade delivers that vibrant green color and deep umami. The milk can be swapped for heavy cream if you want extra richness, or almond milk for a lighter version. Baking powder is non-negotiable here—Clabber Girl is my trusty brand, but check the expiration date. Freshness matters more than brand for this tiny batch.

Store your dry ingredients in airtight containers away from heat and light—they'll stay fresh for 6-12 months. Once mixed, the batter keeps in the fridge for up to 24 hours, though I recommend baking it fresh for that perfect texture. For the cake itself, cool completely on a wire rack before slicing—this prevents crumbling. Leftovers? Wrap tightly in plastic wrap and store for up to 3 days. Freezing isn't ideal for this delicate cake, but you can freeze portions for up to 1 month if needed.

Step-by-step instructions for precision portions of 100-Gram cake

Here's how to craft delicate, perfectly portioned cakes with flawless texture every time.

Start by sifting the 0.25 cup all-purpose flour and 0.25 tsp baking powder together in a medium bowl. This ensures an airy texture by breaking up any lumps and incorporating air. I like to use a fine-mesh sieve for this step—it creates a lighter crumb than just whisking dry ingredients in the bowl.

In a separate small bowl, whisk together the 0.03125 cup milk, 0.5 tsp vanilla extract, and 0.125 tsp salt. This pre-mixing prevents clumping when you combine everything later. Let the milk mixture sit for 2 minutes while you prepare the butter and eggs—this allows the salt to fully dissolve and the vanilla to disperse evenly.

In a stand mixer fitted with the paddle attachment, beat the 0.0625 cup unsalted butter (at room temperature) and 0.125 cup granulated sugar on medium speed for 3-4 minutes. You're looking for a pale, fluffy mixture that nearly doubles in volume—the butter should be completely smooth with no graininess. This creaming process incorporates air, which is crucial for that tender, airy crumb.

Here's the thing—if your butter has cold spots, the mixture won't emulsify properly. Press between your fingers to test: it should feel soft but not greasy. If it's too soft, chill the bowl in the refrigerator for 10 minutes before continuing. The goal is a light, airy consistency that will create pockets for the leavening agents to work their magic.

Add the 2 whole large eggs, one at a time, mixing on low speed after each addition until fully incorporated. Scrape down the sides of the bowl with a silicone spatula to ensure even mixing. Then, gradually add the sifted dry ingredients while mixing on low speed just until combined—you should still see some flour streaks. Overmixing develops gluten, which can make the cake dense.

Now for the flavor variations: if using 0.03125 cup matcha powder, sift it into the dry ingredients before adding to the wet mixture. For 0.03125 cup cocoa powder, add it at this stage as well. Both powders are dense and need to be incorporated gently to avoid creating lumps. Mix just until the batter looks smooth and homogeneous—no more than 10-15 seconds of additional mixing after all ingredients are combined.

Preheat your oven to 350°F and grease four 2-ounce ramekins or mini cake pans (about 3 inches in diameter). Divide the batter evenly among the prepared pans—each should contain approximately 25 grams of batter (about 2 tablespoons). Gently tap the pans on the counter to remove any air bubbles and ensure even distribution.

Bake for 12-15 minutes until a toothpick inserted into the center comes out clean and the edges are light golden brown. The cakes should spring back slightly when pressed gently in the center. Real talk: don't overbake—these small portions dry out quickly, and you want that tender, moist crumb. If using matcha or cocoa, the cakes will have a slightly darker hue but should still be moist when done.

Remove the cakes from the oven and let them cool in the pans for 5 minutes. Then transfer to a wire rack to cool completely—this prevents condensation from making the bottoms soggy. For the best texture, serve at room temperature, allowing the flavors to fully develop. If making ahead, store in an airtight container for up to 3 days at room temperature or 1 week in the refrigerator.

The result should be delicate, moist cakes with a fine crumb and perfect balance of sweetness. The precision of these portions means you can enjoy a single serving without leftovers, and the technique ensures every bite is consistently perfect—no dense centers or dry edges. This is where attention to detail pays off in the most delicious way.

Flavor customization for this dish

Classic Vanilla Twist

Start with the original recipe's vanilla base, then elevate it with ½ tsp lemon zest and 1 tbsp lemon juice for a bright, citrusy kick. The acidity cuts through the sweetness beautifully while adding freshness. For a deeper vanilla flavor, replace the ½ tsp vanilla extract with 1 tsp vanilla bean paste—the flecks of bean add visual appeal and an extra layer of complexity. 🌿

Rich Chocolate Depth

For a decadent chocolate version, incorporate ¼ cup Dutch-processed cocoa powder into the dry ingredients and reduce the flour to ¼ cup minus 1 tbsp to maintain moisture. Add 1 oz (28g) dark chocolate, melted and cooled, to the butter-sugar mixture. Top each cake with a dollop of whipped cream and a sprinkle of flaky sea salt for a sophisticated finish.

Earthy Matcha Elegance

Transform your cake into a vibrant matcha masterpiece by adding 2 tbsp ceremonial-grade matcha powder to the dry ingredients. Replace the vanilla with ½ tsp matcha-infused honey for a subtle sweetness that complements the earthy notes. Garnish with edible gold leaf or white chocolate shavings for a luxurious touch. This version pairs perfectly with earl grey tea for a cohesive flavor experience.

Spiced Chai Delight

Infuse warmth into your cake by adding ½ tsp ground cinnamon, ¼ tsp ground cardamom, and ¼ tsp ground ginger to the dry ingredients. Replace the vanilla with ½ tsp chai spice blend (available at specialty stores) for a cohesive aromatic profile. Serve with a side of spiced chai latte to enhance the cozy flavors. The spices add depth without overpowering the delicate cake texture.

Citrus Zest Burst

Brighten up your cake with 1 tbsp orange zest and 1 tbsp lime zest added to the dry ingredients. Replace the vanilla with ½ tsp orange extract for a citrus-forward flavor. Top each cake with a drizzle of honey and a few toasted coconut flakes for a tropical twist. This variation is perfect for spring or summer gatherings and pairs wonderfully with sparkling lemonade.

Salted Caramel Indulgence

Create a caramel-lovers' dream by adding 2 tbsp caramel sauce (homemade or store-bought) to the butter-sugar mixture. Sprinkle each cake with flaky sea salt before serving. For extra richness, fold 1 oz (28g) cream cheese into the batter. This decadent version is ideal for those who enjoy a balance of sweet and salty flavors, and it pairs beautifully with a glass of bourbon for an after-dinner treat.
