Grate the carrot and place in a medium sized mixing bowl.
Add banana to the carrots and mash well. I like to use a meat or potato masher for this step.
Add all other ingredients to the mixing bowl; add the raisins last.
Mix just until all ingredients are incorporated. There will be lumps.
Divide batter evenly.
Bake for 20-22 minutes, or until a toothpick comes out clean.
Notes
Use the 'scoop and sweep' method when measuring flour instead of packing it in. Simply, spoon flour into the measuring cup and then sweep the top of the measuring cup with a knife to level it off. Prep time includes the time it took me to grate the carrot using a hand-held grater.
