1. Lightly coat twelve 2-1/2-inch muffin cups with cooking spray; set aside. In a small bowl pour boiling water over raisins to cover; set aside.
2. In a medium bowl combine the flour, wheat germ, baking powder, baking soda, salt, and cinnamon. Make a well in the center of flour mixture.
3. In a small bowl combine the egg, buttermilk, brown sugar, and oil. Add the egg mixture all at once to flour mixture. Stir just until moistened (batter should be lumpy). Drain raisins. Gently fold raisins and carrot into batter.
4. Spoon batter into the prepared muffin cups, filling each about three-fourths full. Bake in a 400 degrees oven about 20 minutes or until golden brown. Cool in pan on a wire rack for 5 minutes. Remove from muffin cups. Serve warm.
