Meanwhile, Make the Glaze
Preheat the oven to 350° and line 3 baking sheets with parchment paper. In a small bowl, whisk the flour with the baking powder, baking soda, pumpkin pie spice and salt. In a large bowl, using a handheld electric mixer, beat the butter with the sugar at medium speed until light and fluffy, about 2 minutes. Beat in the egg and vanilla followed by the pumpkin puree and candied ginger. At low speed, beat in the dry ingredients until evenly incorporated.
