Preheat the oven to 350 degrees.

In a medium bowl, combine the egg, peanut butter, oil, vanilla, and honey (optional).

Stir in the carrots, then gradually add the flour and baking soda until well combined.

Pour into a small and greased baking pan. I used a 5.75 x 3 inch mini loaf pan and it was perfect. a 6 cup ring mold also works.

Bake in the oven for 30-40 minutes, (mine was done after 30). Turn onto a wire rack and let cool completely.
