Preheat oven to 375 degrees F.
Fill muffin tin with baking cups and set aside.
In a large bowl whisk together all of your wet ingredients.
Add in all of your dry ingredients and whisk until smooth.
If desired, add chopped walnuts or other mix ins.
Scoop your batter into each baking cup. I like to use an ice cream scoop.
Bake for 20 minutes then start doing the fork test every two minutes until done. This took 24 minutes in my oven, and the fork was almost clean. A few crumbs on the fork is perfect in my book.
Let muffins cool for about 10 minutes then enjoy!
