100g (3.5oz) brown sugar

½ tsp nutmeg
For the filling
2 tsp cornflour

Fire up your Ooni pizza oven. Aim for 180°C (350°F) on the stone baking board inside. You can check the temperature inside your Ooni pizza oven quickly and easily using the Ooni Infrared Thermometer.
First, prepare the crumble topping. In a bowl, combine all the topping ingredients until well combined and set aside.
Add a little olive oil to your Skillet and place inside your Ooni to warm up.
In a small bowl, add 4 tablespoons of boiling water to the cornflour and mix until well combined. Set aside.
Once the Skillet is warm, remove it from the oven and add the apples. Cook in the oven for 5 minutes, or until the fruit has slightly softened.
Remove the Skillet and add the cornflour-water mixture, brown sugar, vanilla extract and maple syrup. Toss well to coat the fruit with all the wet ingredients, then spread around the cranberries. Return the Skillet to the oven and cook for another 5-7 minutes, or until the fruit is a light golden colour.
Top the fruit evenly with the crumble mixture and continue to cook for another 10 minutes, or until the topping is toasted and crunchy.
Remove Skillet from the oven and serve warm, topped with a scoop of vanilla ice cream.
