Prepare the apples:
Peel and chop the apples into small chunks.
In a saucepan, add the chopped apples, cinnamon, sweetener, and water. Cook over medium heat for 5–7 minutes until the apples soften slightly. Transfer to an ovenproof dish.
Preheat the oven: While the apples are cooking, preheat your oven to 180°C (350°F).
Make the crumble:
In a mixing bowl, combine the oats, oat flour, protein powder, sweetener, sugar-free maple syrup, light butter and salt. Mix until it forms a crumbly texture.
Sprinkle the crumble mixture evenly over the softened apples.
Bake: Place in the oven for 20–25 minutes until the topping is golden and crisp.
Serve & Enjoy!
Allow to cool slightly before serving. Enjoy warm on its own, or with Greek yoghurt for an extra boost of protein.
