Ingredients

• 1 3/4 cups all-purpose flour
• 1/2 teaspoon baking soda
• 1/2 teaspoon baking powder
• 1/8 teaspoon salt
• 1 teaspoon nutmeg
• 1/2 teaspoon cinnamon
• 1/2 cup pumpkin puree
• 1/2 cup unsalted butter, softened
• 1 cup brown sugar
• 1 teaspoon vanilla
• 2 eggs
• 1 teaspoon orange zest
• 1/2 cup raisins (optional)
• 8 ounces white chocolate

Instructions

1. Sift together the flour, baking soda, baking powder, salt, nutmeg and cinnamon, set aside.

2. Using a mixer, beat the butter and sugar on high speed until light and fluffy. Add the eggs, vanilla, pumpkin puree and orange zest. Continue to beat until well blended.

3. Add the flour mixture and beat at low speed until just incorporated. Stir in the raisins or dried cranberries, if desired.

4. Refrigerate about 1 hour.

5. Preheat the oven to 350°F Line a baking sheet with parchment. Divide the dough in half.

6. Using lightly floured hands, shape each half into a log about 10 inches long. Place the logs a few inches apart on the baking sheet and bake about 30 minutes, or until brown and firm to the touch.

7. Place the logs on racks and let cool 10 to 15 minutes.

8. Transfer to a cutting boad and slice each log on the diagonal into 12 slices. Place the cooling rack on the baking sheet and arrange slices cut side down on rack.

9. Bake until golden, about 15 to 20 minutes. Watch carefully to avoid burning, and turn once if needed.

10. Remove the slices to a rack to cool completely.

11. Melt the white chocolate (add shortening to chips if using them) and drizzle the biscotti with the chocolate.

12. Refrigerate briefly to set the chocolate.
