Preheat oven to 400 degrees F and line a muffin tin with liners.
In a medium-size bowl, add flour, sugar, baking soda, salt, cinnamon, ginger, and nutmeg. Whisk until it is all well combined and set aside.
In a separate large bowl, mash the bananas. Add eggs, maple syrup, melted butter, and vanilla extra. Use a fork to whisk the eggs and then mix until it is all well combined.
Add the dry ingredients to the wet and use a spatula to gently mix just until all of the dry ingredients are mostly incorporated. It's ok if the dough is still a little lumpy and streaked from the dry ingredients.
Add chopped pecans and use spatula to gently fold them into the batter.
Use a spoon or ice cream scoop to fill muffin liners at least 3/4 full, using all of the batter for 12 muffins.
Bake 25 minutes until the tops of the muffins begin to brown and a toothpick or cake tester pulls clean.
