Preheat the oven to 200C
Grate the apples (no need to peel them) and mash the bananas. Drain the excess liquid from the grated apples using a sieve. Then mix them with all the remaining ingredients in a bowl.
Grease a baking tray with coconut oil.
Scoop a heaped tablespoon of the mix and pat it into flat cookies shape on the tray, do this until all the mixture has been used. Try to get an even amount of sultanas in each cookie as those that are heavier with sultanas are more likely to burn. The mixture should make about 25 cookies.
Then bake the cookies for about 30 minutes until they turn golden brown, at this point take them out the oven and let them cool slightly.
