WHY MAKE IT

A little comfort, a lot of flavor.

The rapid convection circulation of an air fryer makes it practical for small-batch baking without heating a full-sized kitchen oven. These miniature sponge cakes offer a delicate, buttery crumb that cooks in under fifteen minutes. Using individual silicone cups provides flexibility, allowing you to fit them cleanly into circular or rectangular air fryer baskets without metal pan constraints. After a brief cool-down period, seedless berry jam is piped straight into the center of each cake, introducing a burst of fruit tartness that balances the sweet vanilla crumb. Finished with a light dusting of sifted powdered sugar, these single-serving bakes provide an easy, homemade treat with minimal active cleanup.

Air Fryer Convection Dynamics for Baking

Air fryers operate with a high-velocity fan directly above a heating element, making them behave like compact convection ovens. This design browns baked goods much faster than a standard thermal oven. Setting the temperature lower—around 320°F (160°C)—prevents the outer dome from scorching before the core cooks through. Silicone molds protect the cake bases, providing even heat transfer without burning the bottoms.

Injecting the Jam Cores Cleanly

Piping jam inside a baked sponge requires a smooth, seedless fruit preserve. Jam with seeds or large fruit pieces will clog fine piping tips and tear the cake interior. Stir the jam vigorously with a fork or warm it for 5 seconds to reduce viscosity. Insert the metal piping tip halfway into the crown of each cooled cake and squeeze gently until the cake swells slightly, indicating a full center pocket.

Portion Control and Mold Selection

Selecting freestanding food-grade silicone baking cups ensures the cakes hold their shape without slumping under circulating air. Fill the cups no more than two-thirds full to leave headroom for rising. Overfilled molds will dome excessively and can touch the heating element, leading to charred edges. Spacing the molds roughly half an inch apart allows hot air to circulate freely around each cup.

Before you start

Silicone molds are preferred for air fryer baking because they adapt to smaller basket shapes and release delicate sponge easily without tearing. Because air fryers use intense circulating heat from an overhead element, monitor the browning around the 10-minute mark. If the tops brown too quickly before the center sets, balance a loose square of aluminum foil over the molds for the remaining baking time. Warm the jam briefly and stir it until fluid before loading your piping bag for clean, effortless filling.

THE RECIPE

Air Fryer Miniature Sponge Cakes with Jam Centers

6 servings · 20 minutes preparation · 14 minutes cooking · 20 minutes cooling, chilling or resting

Ingredients

Step-by-step instructions

  1. Lightly brush 6 individual silicone cupcake molds with a thin film of neutral cooking oil or melted butter; place them inside the air fryer basket.
  2. Preheat the air fryer to 320°F (160°C) for 3 minutes.
  3. Whisk together 120 g all-purpose flour, 5 g baking powder, and 1 g fine salt in a small mixing bowl.
  4. Beat 100 g softened butter and 90 g granulated sugar in a medium bowl using an electric hand mixer for 2 to 3 minutes until smooth and lightened in color.
  5. Add 2 room-temperature eggs one at a time, mixing well after each addition, then blend in 5 ml alcohol-free vanilla extract.
  6. Gently mix in the flour mixture alternately with 30 ml whole milk, working just until a smooth batter forms.
  7. Divide the batter evenly among the 6 prepared silicone molds, filling each about two-thirds full.
  8. Slide the basket into the air fryer and bake at 320°F (160°C) for 12 to 14 minutes until golden on top and a toothpick inserted into the cake centers emerges clean.
  9. Allow the miniature cakes to rest in their molds for 10 minutes, unmold onto a wire rack to cool for another 10 minutes, then use a piping bag fitted with a small round tip to inject 15 g of seedless jam into the center of each cake, finishing with a dusting of 10 g powdered sugar.

Kitchen notes

Silicone molds are preferred for air fryer baking because they adapt to smaller basket shapes and release delicate sponge easily without tearing.

Warm the jam briefly and stir it until fluid before loading your piping bag for clean, effortless filling.

Storage & make-ahead

Store these miniature cakes in an airtight container at room temperature for up to 2 days, or keep them refrigerated for up to 4 days. If refrigerated, let them stand at room temperature for 15 minutes before serving so the sponge crumb relaxes to its optimal soft texture.

Frequently asked questions

Can I use paper muffin liners instead of silicone molds?

Standard paper liners are too light and will collapse under the weight of the batter or blow around in the air fryer's airflow. If using paper, place them inside sturdy silicone cups or a small air-fryer-safe metal muffin tin.

What type of jam works best for the filling?

Seedless raspberry, strawberry, or apricot jam works best. Ensure the preserve is smooth and free of large fruit chunks so it flows smoothly through a narrow piping nozzle without tearing the tender sponge.

Why did my mini cakes sink after baking?

Opening the air fryer basket repeatedly during the first 8 minutes can cause cakes to collapse due to sudden heat loss. Avoid checking until at least 10 minutes have elapsed so the crumb structure sets properly.
