Mix the apple slices, vanilla custard, casein protein powder and cinnamon together until thick and creamy.
Add the mixture to the centre of the wrap.
Fold the sides in and roll tightly into a burrito.
Lightly spray the outside with cooking oil and sprinkle with sweetener and cinnamon.
Air fry at 200°C for around 6 minutes, flipping halfway, until golden and crispy.
Cut the burrito in half to make 2 serves.
