2 3/4 cups all-purpose flour
1 teaspoon baking powder
1 teaspoon baking soda
1 1/4 teaspoons coarse salt
1 1/2 teaspoons ground cinnamon
1 1/4 teaspoons ground ginger
3/4 teaspoon ground nutmeg
3/4 cup (1 1/2 sticks) unsalted butter, softened
2 1/4 cups packed light-brown sugar
2 large eggs
1 1/2 cups canned solid-pack pumpkin (14 ounces)
3/4 cup evaporated milk
1 teaspoon pure vanilla extract
For the Icing
4 cups confectioners' sugar, sifted
10 tablespoons (1 1/4 sticks) unsalted butter
1/4 cup plus 1 tablespoon evaporated milk
2 teaspoons pure vanilla extract

Put butter and brown sugar in the bowl of an electric mixer fitted with the paddle attachment.
Mix on medium speed until pale and fluffy, about 3 minutes. Mix in eggs. Reduce speed to low. Add pumpkin, evaporated milk, and vanilla; mix until well blended, about 2 minutes. Add flour mixture; mix until combined.
Martha says to use a pastry bag to pipe onto parchment lined pans but I just spooned 1 1/2-inch rounds onto seasoned stone baking sheets, spacing 1 inch apart. Bake cookies about 12 minutes. Cool on sheets on wire racks 5 minutes. Transfer cookies to wire racks; let cool completely.
