Oil a muffin pan. Preheat oven to 350F (180C).
In a small bowl, mix together the chia seeds and warm water. Set aside.
In a separate bowl, mix together the flour, baking powder, baking soda, salt and spices.
In a large bowl, mix together the sugars, oil, vanilla and applesauce. Add chia egg and mix well. Add the dry ingredients into the wet ingredients and mix well without overstirring.
Stir in the oats, apples, and nuts, if using.
Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.
