Preheat oven to 375°

Fill 14 standard muffin tins with paper liners.

1. Place the sugar in a spacious mixing bowl.
2. Sift in the flour, baking powder, baking soda, salt, cinnamon, nutmeg, cloves, and ginger. Whisk to combine.
3. In a separate bowl, whisk together the eggs, buttermilk, vanilla, and melted butter.
4. Add the mashed and chopped bananas to the egg mixture.
5. Stir the egg mixture in to the dry ingredients and mix until just combined – do not overbeat.
6. Add the chopped nuts and mix lightly.
7. Divide the batter evenly among the prepared muffin cups. The cups will be quite full.
8. Bake for 25–30 minutes, or until a toothpick inserted into the center of the muffin comes out clean.
