Directions

1. Preheat oven to 350 degrees. Butter and flour a nonstick 10-inch tube pan; set aside.
2. In a large bowl, sift together flour, baking powder, salt, cinnamon, nutmeg, and cloves. Set aside.
3. In the bowl of an electric mixer fitted with the paddle attachment, cream butter and sugar until light and fluffy. Add eggs, one at a time, and continue mixing for 3 minutes. Add vanilla and zest; beat to combine. Add flour mixture, alternating with buttermilk, beginning and ending with the flour. Add pumpkin and mix until incorporated.
4. Pour batter into prepared pan. Bake until a toothpick inserted into the center of the cake comes out clean, about 1 hour 15 minutes. Cool on a wire rack for 15 minutes. Drizzle with orange glaze.
