Remove the rind from one clementine, and leave the rind on the other one (do remove any stuff that is not edible on the orange - like the stub where the stem was). Process both clementines in a food processor, or blend until you have tiny bits of orange mush. Add it to a mixing bowl.
Add the remaining wet ingredients to the mixing bowl, and then add the dry ingredients.
Combine well and place the batter into cupcake liners or into a loaf pan if you're making bread.
Bake the muffins for 35 minutes, or until the tops are browned and a toothpick comes out clean. A loaf of bread will take about 10 minutes longer to bake (about 45 to 50 minutes).
Cool and enjoy! I store these in the refrigerator and reheat them at 350 degrees F for about 7 minutes.
