Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius) and prepare a 12-cup muffin tin with paper liners.
Add the brown sugar, grated carrots, grated apples, buttermilk, oil, and eggs to a large bowl and whisk together to combine.
Add the flour, baking soda, baking powder, ginger (if using), cinnamon, nutmeg, cloves, and salt to the bowl and combine with a wooden spoon or rubber spatula just until the flour disappears.
Divide the batter evenly between the prepared muffin cups, filling them each about 2/3 full.
Bake at 350 degrees Fahrenheit (175 degrees Celsius) for about 17-18 minutes or until golden brown.
