In the blender, add the clementine, eggs, vegetable oil, sugar, flour, baking powder and salt. Blend on high speed for 45 seconds to a minute or until batter becomes smooth and thick. (If necessary, scrape down sides of blender to make sure everything is incorporated.)
Distribute batter between six lined (or greased) muffin cups.
Bake at 435 for 5 minutes. Lower the temperature to 350 and bake an additional 12-15 minutes or until a toothpick comes out clean.
Notes
** Note - I made this in my Ninja Nutri Pro because I don’t have a traditional blender. It struggled a bit at first, but after scraping down the sides it seemed to work fine. But this batter is very thick so bear that in mind.
