Dice the cleaned and dried apples and place them in a mixing bowl.
Add 1 teaspoon cinnamon and 1 tablespoon maple syrup to the apples in the bowl and mix everything together making sure the apples are coated with the syrup and cinnamon.
Place one half of the mixture into one 6 ounce ramekin and the other half into another 6 ounce ramekin and set them aside.
Crush the 4 graham crackers with a rolling pin or a mini food processor. (this should make about 1/4 cup crumbs) Place the crumbs into a mixing bowl.
Add 3 tablespoons melted butter to the crumbs along with 1/8 cup chopped walnuts and 1/4 cup rolled oats to the crumbs in the bowl and stir to combine all of the ingredients
Spoon the topping mixture over each of the ramekins (the ingredients will overflow a bit, press them down with the back of a spoon) and bake for 30 minutes until the topping turns brown.
