Blend all of the ingredients together in a food processor or blender until you have a dough. If you are not using cocoa powder and stevia then add a little more walnut to bind it together. Equally if you use another sweetener, like sugar, then you may need to reduce the walnuts...basically you are looking for a dough that looks like pastry! Add or reduce the amount of walnuts or coconut flour to achieve this

Remove the dough from the machine and wrap it in clingfilm

Place in the fridge for at least half an hour to make it less sticky to work with

Once cooled, remove a piece about the size of a walnut, roll it into a ball then press it into a hole of a muffin tray until it covers the base and sides

Repeat with the rest of the dough...you should have enough to make 10 small pies

Fill then bake in a pre-heated oven at 190 degrees, 170 degree fan for around 20 minutes or until cooked through
