Preheat oven to 350°F. Grease and flour a loaf pan or muffin tin.
Mix dry ingredients, adding raisins last. Mix wet ingredients in another bowl. Fold together just before baking.
Bake at 350°F for about 60 minutes in a loaf pan or about 30 minutes in a muffin tin. It's done when a toothpick comes out clean from the center.
For quicker results, bake for about 20 to 25 minutes in a 400°F oven. Or for about 23 to 28 minutes at 375°F.
