Preheat oven to 350° F. Line a muffin tin with paper liners.
Mix wet ingredients and orange zest together in one bowl, and the dry in another. Why can't you just mix them all together in one bowl right off the bat? Because baking law SAYS, okay? And because that is how you get a clump of coconut oil or baking powder in the middle of your muffin. Not tasty.
Add wet to dry and mix to combine. Beautiful and smooth.
Fill each muffin-lined cup 2/3 of the way with batter. Bake for 15 to 20 minutes, or until a toothpick inserted in the center comes out clean.
