Add the cranberries, apple chunks, sugar, cornstarch, salt, and cinnamon to a bowl
Stir to combine the filling
In a separate bowl, add the brown sugar, walnut flour, oat flour, rolled oats, and salt.
For the walnuts, simply grind them in a blender until flour texture. You can use pecans as a substitute also
Whisk together all of ingredients to combine
Pour on the melted coconut oil and butter, then stir until mixture is combined
Stir the crisp filling one last time, then transfer to a small baking dish (I used a pie plate)
Top the filling with the crisp topping, and spread it evenly over the top
Bake at 350 degrees for 55 - 60 minutes, until top is browned and bubbly
Serve with vanilla ice cream
