Mist a 7-inch loose-bottomed pan with cake release and line the bottom and sides with non-stick baking paper.
Crush the biscuits in a mini chopper or place in a large sandwich bag and gently crush using a rolling pin. Melt the butter in a saucepan and mix with the crumbs until you have a wet sand texture.
180 g (6.3 oz) Biscoff cookies , 6 tbsp (85g) unsalted butter
Tip the crumbs into the prepared tin and press down firmly to create the base. Chill in the fridge while you make the filling.
MAKE THE CHEESE CAKE FILLING
Place the mascarpone, sweetened condensed milk, Dulce de Leche, vanilla and salt in a mixing bowl. Beat with an electric whisk until smooth.
500 g (18 oz) mascarpone cheese, 395 g ( 14oz) sweetened condensed milk, 2 tsp vanilla bean paste, pinch salt, 3 tbsp Dulce De Leche
Beat in the eggs, mixing on low speed. For an extra-creamy cheesecake strain the filling through a fine sieve. Pour the filling over the base. Tap gently on the countertop to release any air bubbles.
2 large eggs
BAKE THE CHEESECAKE
Place the pan in the basket of your Air Fryer and bake at 140°C / 285°F for 30 minutes.
Reduce the temperature to 120°C / 250°F and bake for further 25-30 minutes or until the cheesecake is set with a bit of a jiggle in the middle. Leave the cheesecake to cool in the Air Fryer basket after you turn it off.
Cover the cheesecake pan with foil or a plate and chill for at least 6 hours and ideally overnight.
DECORATE AND SERVE
Take the cheesecake out of the fridge and run a thin knife blade around the edge to loosen. Release the cheesecake from the pan and place on a plate or cake stand.
Beat the cream, icing sugar and vanilla on medium speed until it holds soft peaks. Toss the sliced bananas in the lemon juice so that they don't brown and pat dry.
240 ml (1 cup) double cream, 60 g (½ cup) icing sugar, 1 tsp vanilla extract, 1 tbsp lemon juice
Drizzle caramel around the edge of the cheesecake, pile the whipped cream on top and add the bananas.
2 bananas, 3 tbsp Dulche de Leche
Drizzle with caramel and sprinkle with the Biscoff crumbs. Slice and serve.
1 tbsp Biscoff cookies

Notes
• Air Fryers are all a little bit different so you might need to adjust the cooking time if you use a different model than the one I tested the recipe on. If the cheesecake is not baked, i.e. mostly set with a slight jiggle in the middle, add a few minutes to the cooking time. • If the cheesecake is browning too quickly you can also reduce the temperature and bake for slightly longer. • Allow the cheesecake to cool in the Air Fryer basket after it has finished baking to avoid cracks. • Chill the cheesecake for at least 8 hours and ideally overnight so that it can set properly before slicing.
