Equipment
- 1 Air fryer
- 1 Springform pan 18 cm
- 1 Mixing bowl
- 1 Electric mixer
- 1 Cutting board
- 1 Knife
- 1 Parchment paper For the bottom of the tin
Ingredients
Cake batter
125 g butter Softened
125 g sugar
1 tsp vanilla sugar
2 eggs
150 g plain flour
1 tsp baking powder
1 pinch salt
2 tbsp milk
Plums
- 400 g plums Ripe and firm
- 1 tbsp sugar
Cinnamon crumble
- 75 g plain flour
50 g light brown sugar
2 tsp cinnamon Ground- 50 g butter Cold, cubed
Instructions
Preparation
- Halve and stone 400 g plums, and toss the halves with 1 tbsp sugar. Leave them to sit while you make the batter.
- Line the bottom of an 18 cm springform tin with baking paper, and butter the sides. The tin needs to stand freely in the air fryer basket with at least 2 cm of clearance all the way around.
- Rub 50 g butter cubes together with 75 g plain flour, 50 g light brown sugar and 2 tsp cinnamon between your fingers, until the mixture resembles coarse crumbs. Put the cinnamon crumble in the fridge while you make the batter.
- Beat 125 g butter together with 125 g sugar and 1 tsp vanilla sugar, until the mixture is light and fluffy. Add 2 eggs one at a time, beating well after each.
- Mix 150 g plain flour, 1 tsp baking powder and 1 pinch salt, and fold it into the batter together with 2 tbsp milk. Stir only until the batter just comes together.
Cooking in the air fryer
- Preheat the air fryer to 160 °C fan for 3 minutes.
- Pour the batter into the springform tin, and smooth out the surface. Arrange the plum halves closely in circles with the cut side up, so the juice stays in the fruit, and sprinkle the cinnamon crumble evenly over the top.
- Place the tin in the air fryer basket, and bake the cake at 160 °C for 35 minutes. Loosely lay a piece of baking paper over the top after 25 minutes if the crumble is getting too dark.
- Test the cake with a skewer in the centre. If it comes out clean, the cake is done. Otherwise, give it another 3-5 minutes at 160 °C.
Serving
- Let the cake cool in the tin for 15 minutes before loosening the edge. The crumble sets as the cake cools.
- Serve the cake warm with whipped cream or a scoop of vanilla ice cream.
Notes
Tips for the perfect result:
Use ripe but firm plums. They hold their shape during baking and don't turn watery. If you lay the halves cut-side up, the juice stays in the fruit instead of soaking into the batter. The cinnamon crumble:
The cinnamon in the crumble is what sets Hilde's cake apart from the Bavarian version, where the crumble is kept plain. Keep the butter fridge-cold and crumble it quickly. If the butter gets warm, the crumble melts together into one layer instead of coarse crumbs. Variation:
Replace half the plums with apricots, or add 40 g chopped almonds to the crumble for extra crunch. Serving:
Serve the cake warm with whipped cream, crème fraîche or vanilla ice cream. Portion size:
The cake is baked in an 18 cm springform tin that fits most air fryer baskets. If your air fryer has a small basket, check that there's at least 2 cm of clearance all the way around the tin.
