Preheat oven to 350°F. Spray mini loaf pans with nonstick cooking spray. You can also line with a small piece of parchment paper, if desired.
In a medium-sized bowl, combine brown sugar, molasses, eggs, and vanilla. Mix until well incorporated.
Next add the sour cream and milk, then mix again until well blended.
Separately combine the dry ingredients (flour, baking soda, baking powder, salt, ginger, nutmeg, cinnamon, and cloves).
Add the dry ingredients to the wet and mix well.
Evenly divide the batter between the 6 loaf pans (I like to use a large cookie scoop - it ends up being 2-3 large scoops per pan).
Place loaf pans in the preheated oven and bake for 30-35 minutes until they spring back to the touch.
Remove from pans and place on a wire rack to cool. Dust with powdered sugar if desired.
