Preheat your oven to 350ºF and line a standard muffin tin with muffin liners.
Combine all the dry ingredients in a medium bowl and set aside.
Whisk together all the wet ingredients in a large bowl.
Gently fold the dry ingredients into the wet until just combined, being careful not to overmix.
Spoon the batter into the muffin tin, filling each about ¾ of the way full.
Bake at 350ºF for 18-22 minutes or until a toothpick inserted into the center comes out clean.
Let cool for 5 minutes in the tin, then transfer to a wire rack to cool completely.
