Preheat oven to 350 degrees. Spray your donut pan with nonstick cooking spray. In a large bowl, stir together flour, baking soda, both sugars, cinnamon and ginger. Beat in butter, egg, milk, and molasses until evenly blended. * If using the Dipping Donutz pan and accessories, follow product directions starting here.
Spoon batter into a zip top bag, and cut off one bottom corner. Pipe batter into each donut mold, up to level with the pan.
Bake for 15-20 minutes, then set aside to cool.
Once donuts are cooled, whisk together milk, powdered sugar, in a wide bowl. Take a cooled donut and dip one side into the prepared frosting, then lift up and place on a cooling rack. Add sprinkles.
