2 1/2 cups all purpose flour
4 tsp baking powder
4 tsp ground ginger
1 1/2 tsp ground cinnamon
1/2 tsp salt
1 cup butter
1 1/2 cups packed dark brown sugar
4 large eggs
1/4 cup grated fresh ginger root

Preheat oven to 350.  Grease and flour a 9 inch bundt pan.  Sift together flour, baking powder, ground ginger, cinnamon, and salt.  Set aside.  In a large bowl, cream together butter and brown sugar until light and fluffy.  Beat in eggs, one at a time, then stir in grated ginger root and vanilla.  Beat in flour mixture alternately with milk, mixing just until incorporated.  Pour batter into prepared pan.  Bake in preheated oven for 45-50 minutes, or until a toothpick inserted into center of cake comes out clean.  Let cook in pan for 10 minutes, then turn out onto a cooling rack to finish cooling.  Dust lightly with powdered sugar before serving.
