Preheat the oven to 200 degrees Celsius (390 degrees Fahrenheit)
Peel and core the apples and cut them into small chunks. Place them in a bowl and top with the lemon juice to stop them browning.
Place a 7 inch in diameter cast iron skillet on the stove on medium-high heat. Add the coconut oil, honey, vanilla extract, cinnamon and nutmeg to the skillet and cook for approximately 2 minutes until hot then add in the apple pieces and stir to coat them in the sauce.
Cook the apples for approximately 8 minutes until they are soft.
While the apples are cooking, in a bowl stir together all of the ingredients for the topping. Spoon the mixture evenly over the apples. Bake in the oven for 10 minutes until the topping is golden in colour.
Serve the crisp topped with coconut whip or lemon cream
