For Cookies:
• 1 ½ cups all-purpose flour

Instructions

1. Preheat oven to 350 degrees and position racks in the upper and lower thirds. Line 2 baking sheets with parchment paper.
2. In a bowl, whisk together the flour, baking soda, ginger, cinnamon and salt. In the bowl of an electric mixer fitted with the paddle attachment, beat the butter and sugar at medium speed until fluffy, about 3 minutes. Beat in the egg and molasses. Add dry ingredients and beat at low speed until well incorporated, scraping down the sides. Drop tbsp size dough onto the baking sheets, 3 inches apart. Bake the cookies for 10-15 minutes, until risen and fallen and slightly firm; shift the sheets halfway through for even baking. Let cool slightly then transfer the parchment paper to racks to cool completely.
3. In the bowl of a electric mixer fitted with the paddle attachment, beat the butter with the confectioners’ sugar at medium speed until light and fluffy, about 3 minutes. Beat in the milk until well combined.
