Combine all the dry ingredients for the mix in a plastic storage container or a quart bag and stir to mix. This will keep several months in the pantry.
To make muffins, combine all the wet ingredients in a bowl. Add the dry ingredients (mix) and stir gently until no streaks of flour remain. Fold in your add-ins. Spoon into muffin cups (each mix makes 12 muffins) and bake at 350 for 18-20 minutes.
