Step 1

Preheat the oven to 350 F. In a large bowl cream together the butter and brown sugar, beat in the molasses and egg. Whisk together the flour, baking soda, salt, cinnamon, ginger, cloves and nutmeg in a separate bowl. Add the dry ingredients to the wet and stir until well combined.

Step 3

Press into the bottom of a greased 9 x 13 inch baking pan. Bake for 14-16 minutes or until a toothpick inserted comes out with a few crumbs. Let cool completely before glazing.

Step 5

To make the glaze, mix together the powdered sugar, vanilla and enough of the milk to make a smooth consistency that is easy to drizzle. Drizzle onto cooled bars. Cut into squares.
