Preheat oven to 350oF and line a 12-cup muffin tin with papers.
Whisk dry ingredients until well blended. Mix in oil and water to create a thick, spoonable batter. Do not over-mix.
Spoon batter evenly into muffin cups, filling them to two-thirds full.
Bake for 18-25 minutes. The muffins are done when the tops spring back to a light touch or an inserted toothpick comes out clean.
