What You’ll Need
For the Cake:
- 1 large egg (room temperature works best)
- 1/2 cup granulated sugar (100g)
- 1/2 cup all-purpose flour (65g, sifted)
- 2 tablespoons butter (melted and cooled slightly)
- 2 tablespoons milk (whole milk preferred)
- 1/2 teaspoon vanilla extract
- 1/2 teaspoon baking powder
- Pinch of salt
For Optional Dusting:
- Powdered sugar for serving
- Fresh berries optional but delicious
Substitutions:
- Butter → vegetable oil or melted coconut oil
- Milk → almond milk or oat milk for dairy-free
- Vanilla → almond extract or lemon zest
- All-purpose flour → cake flour for extra tenderness (use same amount)
Step-by-Step Directions
- Preheat your oven to 350°F (175°C) and grease a 6-inch round cake pan or line it with parchment paper. If you only have an 8-inch pan, the cake will be thinner but still delicious.
- Prepare your egg mixture. In a medium mixing bowl, crack the egg and beat it vigorously with a whisk or electric mixer for 2-3 minutes until it becomes pale and frothy. This step is crucial for creating volume in your single-egg cake.
- Add the sugar gradually. While continuing to beat, slowly add the granulated sugar. Beat for another 3-4 minutes until the mixture is thick, pale, and ribbons form when you lift the whisk. This process is called “ribbon stage” and creates the cake’s structure.
Pro Tip: The mixture should nearly double in volume and hold its shape for a few seconds when drizzled back into the bowl. Don’t rush this step—it’s what makes your cake light and airy!
- Combine dry ingredients. In a separate bowl, whisk together the sifted flour, baking powder, and salt. Sifting is important for a tender crumb, so don’t skip it.
- Fold in the flour mixture. Using a rubber spatula, gently fold the dry ingredients into the egg mixture in two additions. Use a cutting and folding motion, rotating the bowl as you go. Be gentle—overmixing will deflate the air bubbles you worked so hard to create.
- Add wet ingredients. In a small bowl, combine the melted butter, milk, and vanilla extract. Fold this mixture into the batter until just combined. The batter should be smooth and light.
- Pour and bake. Transfer the batter to your prepared pan and gently tap it on the counter to release any air bubbles. Bake for 18-22 minutes or until the top is golden brown and a toothpick inserted in the center comes out clean.
- Cool properly. Let the cake cool in the pan for 5 minutes, then turn it out onto a wire rack to cool completely. This prevents the bottom from becoming soggy.
Important: Avoid opening the oven door during the first 15 minutes of baking, as this can cause the delicate cake to collapse.
How to Serve
This versatile sponge cake shines with simple accompaniments:
Classic serving: Dust with powdered sugar and serve with a cup of tea or coffee. The light texture pairs beautifully with hot beverages.
Elegant presentation: Layer with whipped cream and fresh strawberries or raspberries. The cake’s mild flavor lets the fruit shine.
Afternoon treat: Serve thin slices with jam and clotted cream for a British-inspired tea time.
Birthday cake: Use as a base for buttercream frosting or simple glaze. The single layer makes it perfect for intimate celebrations.
Expert Tips for Success
Temperature matters: Room temperature ingredients blend more easily and create better volume. Take your egg out of the fridge 30 minutes before baking.
Don’t overmix: Once you add the flour, fold gently and stop as soon as everything is combined. Overmixing develops the gluten and creates a tough cake.
Storage: Store covered at room temperature for up to 3 days. For longer storage, wrap tightly and freeze for up to 1 month.
Scaling up: To make a larger cake, simply double or triple the recipe. Use a 9-inch pan for a double batch.
Flavor variations: Add 1 tablespoon cocoa powder (reduce flour by 1 tablespoon) for chocolate, or add lemon zest and a splash of lemon juice for citrus flavor.
Baker’s Secret: For extra height, separate your egg and whip the white to soft peaks before folding it in at the end. This creates an even more dramatic rise!
Common Questions
Can I make this cake without an electric mixer?
Yes! While an electric mixer makes the job easier, you can whisk by hand. It will take about 8-10 minutes of vigorous whisking to achieve the proper ribbon stage, but it’s absolutely doable.
Why did my cake turn out dense?
The most common reasons are not beating the egg and sugar long enough, overmixing after adding flour, or using cold ingredients. Make sure to achieve the ribbon stage and fold gently.
Can I use this recipe for cupcakes?
Absolutely! Divide the batter among 6 cupcake liners and bake for 12-15 minutes. Check with a toothpick for doneness.
What if I only have salted butter?
No problem! Just omit the pinch of salt from the recipe. The small amount of salt in the butter won’t affect the final result.
Can I add mix-ins like chocolate chips?
Yes, but use them sparingly—about 2 tablespoons maximum. Too many add-ins can weigh down the delicate batter. Toss them in a little flour before folding in to prevent sinking.
