Spiced Pumpkin-Molasses Cake

1. Preheat oven to 350°F. Lightly grease a 10-inch round cake pan. Whisk together flour, pie spice, baking soda, baking powder, and salt in a bowl; make a well in center of mixture. Whisk together molasses, pumpkin, buttermilk, oil, and egg in a second bowl. Pour wet ingredients into well of dry ingredients, and whisk just until combined. Transfer to prepared pan. 

2. Bake until a wooden pick inserted in center comes out clean, 50 to 55 minutes. Cool cake in pan on a wire rack 10 minutes, then invert onto rack to cook completely.

3. Just before serving, dust with confectioners’ sugar, using a festive stencil made from parchment paper (get the template), if desired.
