Beat oil, sugar, eggs, and molasses in a large mixing bowl. Whisk together the dry ingredients in a small bowl. Stir into the sugar mixture till well combined. Roll dough into small balls and roll in sugar.
Bake on lightly greased cookie sheets at 350° for about 6-7 minutes. Cool completely on wire racks.
Combine chips and oil in a small glass bowl. Microwave at 50% power, stirring every 30 seconds until smooth. Dip cookies halfway into the white chocolate and lay on parchment paper or silicone pan liners till set.
Notes
The 2 tablespoons of ginger is not a mistake. It's what makes them really good. The spiciness is a perfect balance for the white chocolate, trust me!
When you get to the last of the cookies, it will be hard to dip them. You can just spread the chocolate over the top of them, kind of like frosting.
