Preheat the oven to 180 degrees Celsius (350 degrees Fahrenheit)
Combine all ingredients in a large bowl along with about 14 tablespoons of water, until it forms a firm dough - add the water a few tablespoons at a time so that you don’t add too much!
You can keep this pastry dough in the fridge for up to a day if you like, but there is no need to chill it before using
Divide the pastry into two and add one half to a greased pie dish. Use your fingers to carefully press it across the bottom and up the sides of the dish (I used a 9inch/22.5cm pie dish)
Lay out a sheet of greaseproof baking paper on a counter and use a rolling pin to roll out the remaining pastry dough into a circular shape large enough to cover the pie
Once you have this ready, transfer the apple mixture into the pie crust - please don’t do this before you have the top ready, as the warm apple mixture will melt the coconut oil in the pie crust, making it harder to work with
Now place the top layer of pastry on top of the pie crust - you can do this easily by picking up the baking paper from the counter and flipping it over so that it’s resting paper side-up on top of the pie
Once the top layer of pie crust is comfortably sitting on top of the pie, carefully peel off the baking paper
Use your fingers to secure the top layer of crust on top of the crust, by pressing down on all the edges around the pie, making sure they are properly sealed
You can use a fork or your fingers to create a pretty pattern around the edge if you like
Use a knife to create a small slit in the middle of the top layer
Bake in oven for around 30 minutes, until the pastry crust is firm to the touch and golden brown
Leave to cool a little before cutting, but it tastes best served warm from the oven!
Keeps covered in the fridge for up to a few days
