Instructions: Preheat the oven to 325 degrees. Butter a 12-cup bundt pan with 1 teaspoon of the butter and set aside.

In a large bowl using an electric mixer, cream the butter, brown sugar, and sugar. Add the sweet potatoes and beat until light and fluffy. Add the eggs one at a time, and beat after each addition.

Into a bowl, sift together the flour, soda, powder, salt, cinnamon, ginger, allspice, and nutmeg. Add to the sweet potato mixture a third at a time. Fold in the nuts and vanilla. Pour into the prepared pan and bake until a tester inserted into the center comes out clean, about 1 hour to 1 hour and 10 minutes. Remove from the oven and let cool for 10 minutes in the pan.

While the cake is resting in the pan, in a bowl, combine the confectioners sugar, orange juice, and orange zest. Stir well to combine and make a tight glaze, adding more orange juice 1/2 teaspoon at a time to achieve a pourable consistency.

Turn out onto a wire rack. While the cake is still warm, drizzle the orange-sugar glaze to evenly coat. Cool completely before cutting.

This recipe yields 10 to 12 servings.
