Preheat oven to 350°F. Spray a muffin pan with nonstick spray or line with cupcake liners. Set aside.
In a medium bowl mash banana's. Add melted butter and sugars and whisk until smooth. Add the eggs, vanilla and sour cream.
Add the flour, baking powder, baking soda, salt, cinnamon, nutmeg and ginger. Fold in grated carrots.
Spoon batter into prepared muffin pan. You want to batter to be ¾ filled in each muffin cup. Sprinkle tops of batter with turbinado sugar.
Bake for 17-20 minutes, or until a toothpick inserted in the middle of the muffin comes out clean. Allow to cool.
Notes
Make sure all ingredients are room temperature before making.Grating the carrots is better than using shredded so that there are small bits throughout each muffin.Topping the muffins with coarse turbinado sugar is what gives the muffins a slightly crispy/crunchy top. If wanting to make mini muffins bake at 350 F for about 10-12 minutes.I have given both cups and grams as measurements. Grams will be more precise, especially when measuring flour. If you don’t have a kitchen scale, no problem! Just lightly spoon flour into your measuring cup to insure its not packed in there. Light and fluffy is the key.
