Shred the apple using a cheese grater or food processor. Set aside some apple slices for topping.
In a large bowl, mix together the dry ingredients and make a well in the center. Add in the wet ingredients and mix all together. Mix in the shredded apple.
Fold in the walnuts and dates. Pour the oatmeal mixture into a baking dish greased with coconut oil. Top with the remaining chocolate chips. Bake for 35-40 minutes at 350° or until the outer edge of the bake turns golden brown.
Allow it to cool before serving. Slice into pieces and enjoy!
