Mix together the crumble topping ingredients in a mixing bowl.
50 g Oats, 2 tablespoon Butter, 2 tablespoon Honey, 1 teaspoon Light Brown Sugar, 1 teaspoon Cinnamon, 1 teaspoon Plain Flour
Cut the apples in half through the stem, then core them and remove the seeds.
3 Apples
Brush melted butter over the cut sides of the apples with a pastry brush, then sprinkle with the ground cinnamon.
1 tablespoon Butter, ½ teaspoon Cinnamon
Spoon the oat crumble topping onto each apple (compacting it down with a spoon) and place them in the air fryer basket.
Air fry at 180C (350F) for 12-15 minutes until the apple is tender and the crumble is golden brown. Start testing the apples after 10 minutes.
