Line a 9 inch loaf pan with parchment and set aside.
Preheat your oven to 350 degrees Fahrenheit.
In a medium mixing bowl, whisk together flour, baking soda, ginger, nutmeg, and salt.
In a large mixing bowl, mix together the brown sugar, butter, and molasses. Add the vanilla and eggs, and mix until well combined.
Alternate adding the dry mixture and the buttermilk, folding together until just combined.
Pour into the parchment lined loaf pan and smooth out evenly.
Bake 45-50 minutes, careful not to over bake.
Allow the bread to cool completely.
Then, sift the powdered sugar over top.
Slice and enjoy.
