NOTES:
*Store muffins in an airtight container in the refrigerator for up to 1 week or in a freezer bag or freezer-safe container in the freezer for up to 3 months.
RECIPE ADAPTATIONS:
*For sweeter muffins, add 1/3 cup to 1/2 cup of brown sugar or white sugar.
*Grate in 1 to 2 tablespoons of orange zest if you have fresh oranges on hand for a zesty muffin.
*Use any type of apple you like. One granny smith apple, gala apple, fuji or pink lady apple is all you need.
*For an egg-free version, replace the large eggs with two flax eggs. To do so, combine two tablespoons of ground flax seed with 5 tablespoons of water and wait for it to thicken for 15 minutes, stirring occasionally, before using it as an egg replacer. The muffins will turn out dense and not as fluffy.
