Preheat oven to 350º F. Line a muffin tray with paper muffin cups.
In a large bowl, whisk together the flour, sugar, baking soda, cinnamon, and salt; set aside.
In another bowl, whisk together the eggs, olive oil, applesauce, and vanilla extract. Once cohesive, gently stir in the grated apple, chocolate chips, and toasted coconut if using. (Or your substitution.)
Slowly add the dry ingredients to the wet ingredients, stirring constantly, until everything is well combined.
Spoon the mixture into the paper cups right up to the tops of the cups.
Bake for 20-25 minutes, or until a cake tester/toothpick comes out clean when tested.
