Directions

1. Preheat oven to 350°F. Generously butter bundt pan and dust with flour, knocking out excess.
   
2. Bring Guinness and molasses to a boil in a large saucepan and remove from heat. Whisk in baking soda, then cool to room temperature.
   
3. Sift together flour, baking powder, ginger, cinnamon, cloves, nutmeg, and cardamom in a large bowl.
   
4. In a medium bowl whisk together eggs, brown sugar and sugar. Whisk in oil, then molasses mixture. Add to flour mixture and whisk until just combined.
   
5. Pour batter into bundt pan and rap pan sharply on counter to eliminate air bubbles. Bake in middle of oven until a tester comes out with just a few moist crumbs adhering, about 50 minutes.
   
6. Cool cake in pan on a rack 5 minutes. Turn out onto rack and cool completely. Serve cake, dusted with powdered sugar.
