Preheat oven to 350 degrees Fahrenheit. Combine together dry ingredients in medium bowl and stir together.
Using a stand mixer, beat both sugars, vegetable oil, and mashed banana together on medium speed for 5 minutes.
Add in the eggs one at a time until fully incorporated.
Add your dry ingredients to mixer and beat until well combined then fold in your finely pulsed carrots.
Spray or line your muffin tins and then fill each one ¾ full. Bake for 25 minutes.
Notes
*If you don't mind the carrots being hardly noticeable or even prefer them so pulse the carrots in a food processor until smaller than the size of rice.
