Preheat oven to 350 degrees F and spray a 9-inch Bundt cake pan with non-stick spray.
In a large bowl, whisk together the flour, baking powder, baking soda, ginger, cinnamon, and nutmeg.
In another large bowl, beat together the oil, brown sugar, molasses, and vanilla until combined. Beat in the eggs, 1 at a time until combined.
Alternating between the two, gradually beat in the sour cream and dry ingredients until combined and smooth.
Pour the cake mixture into the Bundt pan.
Bake for 50-65 minutes or until a toothpick comes out clean.
Allow cooling for 10 minutes before placing onto a wire rack.
