Using an air fryer to bake a small vanilla sponge cake offers a convenient alternative to the conventional oven, particularly for making individual portions or small cakes in a single batch. The primary challenge with air fryers is their rapid airflow, which can dry out delicate baked goods like sponge cakes. To solve this, we use a specific technique involving a covered baking vessel and reduced temperature settings to retain moisture while allowing the exterior to set.
Recipe Overview
This recipe yields one small cake, suitable for two people or as a single serving dessert. The total time includes preparation and a cooling period before serving.
- Yield: 1 small cake (serves 2)
- Preparation Time: 15 minutes
- Air Frying Time: 10–12 minutes
- Total Elapsed Time: Approximately 30 minutes (including cooling)
Equipment Requirements
Success with this recipe depends on the use of a heat-resistant container that fits comfortably within your air fryer basket without blocking airflow. We recommend a small ceramic ramekin or a glass baking dish with a diameter of approximately 6–7 inches (15–18 cm) and a depth of about 2 inches (5 cm). Ensure the container does not touch the heating element; if necessary, use a heat-proof paper liner or silicone mat to protect the appliance.
Ingredients
All measurements are in grams for precision. Do not substitute volume cups with weight unless you have a reliable conversion tool.
- Sugar: 100g granulated sugar, room temperature
- Baking Powder: 3g baking powder
- Egg: 50g whole egg (approx. 1 large), room temperature
- Milk: 40g whole milk, room temperature
- Vanilla Extract: 2g pure vanilla extract
- Butter: 30g unsalted butter, melted and cooled
- Flour: 100g all-purpose flour, sifted
Method
Follow these steps to ensure a consistent, moist sponge cake texture.
- Preparation: Preheat your air fryer to 150°C (300°F). This lower temperature is crucial for baking cakes in an air fryer, as it mimics the gentle heat of a conventional oven without drying out the batter.
- Mixing Dry Ingredients: In a medium bowl, sift together the flour and baking powder. Sifting removes lumps and ensures even distribution of leavening agents.
- Combining Wet Ingredients: In a separate small bowl, whisk the egg, milk, and vanilla extract until well combined. Add the melted butter and stir until fully emulsified.
- Combining Batters: Gently fold the dry ingredients into the wet mixture using a spatula. Be careful not to overmix, as this can develop gluten and result in a tough texture. The batter should be smooth but slightly lumpy.
- Preparing the Vessel: Lightly grease the inside of your chosen ramekin or baking dish with a small amount of butter or oil to prevent sticking.
- Batter Transfer: Pour the batter into the prepared vessel, filling it no more than three-quarters full. This allows room for expansion during baking.
- Air Frying: Place the ramekin in the center of the air fryer basket. Cook at 150°C (300°F) for 10 minutes. Do not open the appliance frequently, as this can drop the internal temperature and affect rising.
- Checking Doneness: After 10 minutes, check the center. The cake is done when a wooden skewer inserted into the center comes out clean or with only a few moist crumbs attached. The top should be set but not browned; if needed, cover loosely with foil for the final two minutes to prevent browning.
- Removing and Cooling: Carefully remove the ramekin from the air fryer using oven mitts. Let the cake cool in the vessel for at least 10 minutes before unmolding. This helps it hold its shape and prevents collapsing.
Troubleshooting
Here are common issues and their solutions:
- Cake is dry or crumbly: The air fryer’s rapid airflow can dehydrate the cake. Ensure you preheat at a lower temperature (150°C/300°F) and cover the top with foil if it browns too quickly.
- Cake is undercooked in the center: If the batter remains liquid after 12 minutes, reduce the heat to 140°C (285°F) and extend cooking time by 2–3 minutes. Avoid overfilling the vessel, as this traps steam and prevents even heating.
- Cake collapses when unmolded: Ensure the cake has cooled completely before removing it from the dish. Also, check that your ramekin is not too tight on the sides, which can restrict expansion.
Serving and Storage
This sponge cake is best served at room temperature or slightly warm, as cold temperatures can make it denser. You may dust with powdered sugar or serve with a dollop of whipped cream. Store the cake in an airtight container at room temperature for up to 2 days, or refrigerate for up to 3 days. Reheat slices in the air fryer at 150°C (300°F) for 2–3 minutes to restore softness.
Frequently Asked Questions
Can I use a metal baking dish instead of a ramekin?
Yes, but ensure the metal dish is small enough to fit snugly in the air fryer without touching the heating element. Metal conducts heat faster than ceramic, so you may need to reduce cooking time slightly.
Is this cake suitable for baking with other ingredients like fruit?
While you can incorporate fresh berries into the batter or top the finished cake, adding too many liquid-rich fruits before baking may make the sponge soggy. It is best to add delicate toppings after cooling.
How do I know if my air fryer model requires preheating?
Most modern air fryers benefit from preheating for consistent results, especially with baked goods. If your manual suggests otherwise, you may skip this step, but allow the appliance to run empty for 3–5 minutes before adding the batter.
