1. Line 12 muffin tins with muffin wrappers and preheat oven to 375 degrees Fahrenheit.
2. In a large mixing bowl, combine all dry ingredients. In a separate bowl or large measuring cup, combine all wet ingredients and add slowly to dry ingredients. Mix by hand until just combined. (Tip: The key to fluffy muffins is not over-mixing the batter!)
3. Pour batter into prepared muffin tins and bake in preheated oven for 15 to 18 minutes, or until a toothpick inserted comes out clean.
