Preheat oven to 400 degrees. Lightly grease muffin tins and set aside.
Combine first 10 ingredients in a large mixing bowl; make a well in the center. In a separate bowl, combine eggs, milk and oil. Add to dry ingredients, stirring just until combined.
Spoon into prepared muffin cups, filling 2/3 full; bake 20-25 minutes. Remove from pans immediately. For mini muffins, cut baking time roughly in half.
