Preheat your oven to 350 degrees. If you are using a dark coated muffin pan, you will need to lower your oven temperature to 325 degrees. Also, put cupcake liners in your muffin pan, or spray with cooking spray.
Mix all ingredients together in a mixing bowl.
Pour batter into the muffin cups, filling them 3/4 of the way full.
Bake for 15-18 minutes. If you over bake your muffins, they will be dry.
