Combine first 6 ingredients in a large bowl; stir in raisins. Make a well in center of mixture. Combine egg and next 3 ingredients in a small bowl. Add to dry ingredients, stirring just until dry ingredients are moistened (batter will be very thick).
Spoon batter into muffin pans coated with cooking spray, filling two-thirds full. Bake at 400° for 15 minutes.
Note: Do you have a tough time getting out the door to exercise in the morning? It helps if you can keep in mind just how good exercise is for you. Scientific research has shown that exercise helps reduce your risk of heart disease, high blood pressure, stroke, adult-onset diabetes, osteoporosis, and cancer. So put on your jogging shoes--then enjoy a healthy muffin and juice when you return.
