Preheat the oven to 375 degrees.
Combine the wet ingredients in a large bowl and mix well. In a separate bowl, combine the dry ingredients, mixing with a fork.
Add the dry ingredients to the wet ingredients, and gently fold the batter together until thoroughly combined. Do not over mix.
Grease the muffin tin with butter or nonstick stray and evenly distribute the batter. Bake at 375 for about 30 minutes, or until a toothpick comes out clean.
Let the muffins cool for about 30 minutes. They will last up to 4 days in the fridge in an airtight container and up to 3 months in the freezer! Be sure they have fully cooled before storing.
