Ingredients for 500g cake
Nine ingredients transform into a restaurant-quality 6-inch cake with a tender crumb and crisp edges.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | ¼ cup | Softened to room temperature |
| Granulated Sugar 🍚 | ½ cup | Superfine preferred for smooth texture |
| Large Eggs 🥚 | 2 whole | Room temperature for even mixing |
| All-Purpose Flour 🌾 | ½ cup | Sifted for light batter |
| Baking Powder 🍞 | ½ tsp | Aluminum-free for tender crumb |
| Pure Vanilla Extract 🌿 | 1 tsp | High-quality Madagascar bourbon |
| Diamond Crystal Kosher Salt 🧂 | ¼ tsp | Fine grain preferred |
| Vegetable Oil 🫒 | 1 tbsp | For greasing the pan |
| Cornstarch 🌾 | 1 tbsp | For crisp edges |
The butter quality makes all the difference here—Plugrá or Land O'Lakes are reliable choices, but avoid salted varieties. Room temperature butter ensures even mixing without lumps, so take it out of the fridge 30 minutes before starting. For the sugar, superfine dissolves more smoothly, but regular granulated works if pulsed in a food processor. The baking powder is critical: Bob's Red Mill aluminum-free is my go-to for consistent results. If you're using regular flour, sift it with the baking powder to prevent clumps in the batter.
No vanilla extract? Vanilla bean paste works beautifully—just use half the amount. Short on cornstarch? Arrowroot powder at the same quantity creates equally crisp edges. The eggs should be at room temperature, but if you're in a rush, microwave them whole for 40 seconds to warm them up. For a richer flavor, substitute half the butter with dark brown sugar, though the texture will be slightly denser. Always measure flour by spooning it into the cup and leveling—don't scoop directly from the bag, or you'll end up with a dry cake.
Prep the batter up to 24 hours ahead and refrigerate—it develops better flavor overnight. Grease your 6-inch round pan thoroughly with vegetable oil and line the bottom with parchment for easy removal. The cake keeps well at room temperature for 2 days or in the fridge for 5 days. For longer storage, wrap tightly in plastic and freeze for up to 3 months. Reheat slices at 350°F for 5 minutes to restore freshness.

Step-by-step instructions for single-serve cake mastery
This one-bowl method delivers flawless texture and perfect rise every time.
Prepare the Pan and Combine Wet Ingredients
Preheat your oven to 350°F and lightly grease a 6-inch round cake pan using the 1 tablespoon vegetable oil. This ensures easy release later. Line the bottom with parchment paper for extra insurance against sticking.
In a medium mixing bowl, combine the 0.25 cup unsalted butter and 0.5 cup granulated sugar. Using an electric mixer on medium speed, beat for 2-3 minutes until light and fluffy. This step incorporates air, which creates that signature tender crumb. The mixture should nearly double in volume and become pale in color.
Add the 2 whole large eggs, one at a time, mixing well after each addition. Then stir in the 1 teaspoon pure vanilla extract. This creates a smooth, homogenous base that will yield a perfectly even cake texture. The eggs should be fully incorporated before moving to the next step.
Incorporate Dry Ingredients for Lightness
In a separate bowl, sift together the 0.5 cup all-purpose flour, 0.5 teaspoon baking powder, 0.25 teaspoon diamond crystal kosher salt, and the 1 tablespoon cornstarch. The cornstarch creates that desirable crisp edge while maintaining a tender interior.
With the mixer on low speed, gradually add the dry ingredients to the wet mixture. Mix just until combined—you should still see small flour streaks. Overmixing develops gluten, which can make the cake dense. The batter should be smooth and thick, with a consistency similar to heavy cream.
This is where the magic happens: the baking powder will react with the liquid to create air pockets, while the cornstarch ensures that signature crisp edge we all crave. The batter should hold its shape when dropped from a spoon but still be pourable.
Bake to Golden Perfection
Pour the batter into the prepared pan and smooth the top with a spatula. Place the pan in the center rack of your preheated oven and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. The cake should spring back slightly when pressed gently in the center.
Watch for the edges to turn golden brown while the center remains slightly underbaked. This is normal—cakes continue cooking after removal from the oven. If the top browns too quickly, tent loosely with aluminum foil after the first 15 minutes of baking.
Once done, remove from the oven and let the cake cool in the pan for 10 minutes before transferring to a wire rack to cool completely. This gradual cooling prevents cracking and allows the cake to set properly for clean slicing.
Serve with Confidence
The cake should have a moist, tender crumb with a slightly crisp edge from the cornstarch. It should hold its shape when sliced but still be soft to the touch. For best results, serve at room temperature to appreciate the full texture and flavor.
This single-serve cake delivers restaurant-quality results with minimal effort. The one-bowl method simplifies cleanup while ensuring perfect texture every time. The combination of baking powder and cornstarch creates that ideal balance of tender crumb and crisp edge that makes this cake truly special.
Pro Tips For Making 500g Cake
- Cream Butter Slowly: Beat the butter and sugar until it’s pale and fluffy—about 3-5 minutes with an electric mixer. I learned this the hard way: rushing it leaves pockets of air that collapse in the oven, giving you a dense cake instead of a light one. (Yes, even if you’re impatient like me.)
- Room-Temp Eggs Matter: Let eggs sit in warm water for 5 minutes before cracking them—this prevents streaks in the batter. Cold eggs mix unevenly, and you’ll end up with a cake that looks like it’s fighting with itself. Trust me, your crumb structure will thank you.
- Sift Dry Ingredients: Sift flour and baking powder together before folding into the wet mix—this aerates the batter and ensures even baking. I skipped this once and got a cake with a weird, uneven texture. Now I sift like it’s my job.
- Don’t Overmix Wet Ingredients: Stop folding the flour in once it’s just combined—overmixing develops gluten, which turns your tender cake into a tough loaf. Think "damp crumbs," not "glue." I’ve ruined cakes this way more times than I’ll admit.
Best sauces and condiments for these flavors
Classic Vanilla Glaze
This simple 2-ingredient glaze elevates your cake to bakery-level perfection. Mix ½ cup powdered sugar with 1 tablespoon heavy cream or milk, then drizzle over the cooled cake. For extra shine, add ½ teaspoon vanilla extract to the glaze. Let it set for 10 minutes before serving—this creates a smooth, glossy finish that pairs beautifully with the cake's tender crumb. 💛
Lemon Curd Swirl
Add a bright citrus twist by swirling ¼ cup lemon curd into the batter before baking. I use Smucker's Classic Lemon Curd for consistent results. The curd's tangy sweetness cuts through the richness of the cake, creating a delightful contrast. For a more intense flavor, substitute half the butter with lemon zest-infused butter—simply mix 1 teaspoon lemon zest into softened butter before creaming.
Chocolate Ganache Drizzle
For chocolate lovers, melt 4 ounces dark chocolate (I recommend Ghirardelli 60% cocoa) with 2 tablespoons heavy cream until smooth. Drizzle over the cake while still warm, allowing it to partially set before serving. This adds a luxurious, velvety texture that complements the cake's crisp edges. For a lighter option, use white chocolate ganache—melt 4 ounces white chocolate with 1 tablespoon cream and drizzle generously.
Berries and Whipped Cream
Fresh berries and whipped cream are a match made in heaven for this cake. Top with raspberries, strawberries, or blueberries for a pop of color and natural sweetness. Whip ½ cup heavy cream with 1 teaspoon powdered sugar until soft peaks form, then dollop alongside the cake. The acidity of the berries balances the cake's richness, while the whipped cream adds a light, airy contrast. Serve immediately for the best texture. 🍓
Caramel Sauce
Drizzle warm homemade caramel sauce over the cake for a decadent touch. I use a simple recipe: combine ½ cup granulated sugar and 2 tablespoons heavy cream in a saucepan, cooking over medium heat until golden brown. Pour over the cake while it's still slightly warm for a gooey, irresistible finish. For a quicker option, use store-bought caramel sauce—just heat it gently to loosen before drizzling.
Salted Caramel Drizzle
Take the caramel sauce to the next level by adding a pinch of flaky sea salt (like Maldon) on top. The salt enhances the caramel's sweetness, creating a sophisticated flavor profile that feels like a dessert from a high-end patisserie. Sprinkle ¼ teaspoon salt over the drizzled caramel just before serving—this balances the sweetness and adds a delightful crunch. 💡

Frequently asked questions
Can I make this cake in a different pan size?
Yes, but you'll need to adjust the baking time. For a 7-inch pan, bake for 20-25 minutes at 350°F, while an 8-inch pan requires 30-35 minutes. Always use a toothpick test to check doneness. The cake batter yields about 500g, so a larger pan will create a thicker slice. For a smaller 5-inch pan, reduce baking time to 18-22 minutes.
Why does my cake come out dense instead of tender?
Overmixing the batter or using cold ingredients are common culprits. Always mix dry ingredients just until combined (small flour streaks remain), and ensure your butter and eggs are at room temperature. Another tip: measure flour by spooning and leveling—don't scoop directly from the bag. The cornstarch in this recipe helps create crisp edges while maintaining tenderness, so don't skip it!
How do I store leftover cake?
Wrap the cake tightly in plastic wrap or place it in an airtight container to keep it fresh. At room temperature, it stays good for 2 days, while refrigeration extends freshness to 5 days. For longer storage, freeze the cake for up to 3 months. To serve, let it sit at room temperature for 30 minutes before slicing for the best texture.
Can I substitute butter with oil?
You can try, but the texture will differ. Replace the 0.25 cup butter with 0.25 cup vegetable or canola oil, but reduce the sugar slightly to 0.4 cup to compensate for the oil's natural sweetness. The cake will be moister but slightly less tender. For best results, stick with butter—it creates that signature rich flavor and tender crumb this recipe is known for.
What's the secret to a perfectly domed cake?
Bake the cake in the center of your oven and avoid opening the door during the first 20 minutes of baking. The baking powder in this recipe helps create lift, but a hot oven and stable temperature are key. For extra insurance, place a small piece of aluminum foil on the cake's edges after 15 minutes to prevent over-browning while maintaining the dome shape.
