1

Preheat the oven to 350°F. Line a baking sheet with foil; lightly spray with nonstick spray.

2

Sift the flour, cocoa, espresso powder, cinnamon, baking powder, and salt into a medium bowl. Whisk together the sugar, egg, and vanilla in a small bowl until frothy. Add the egg mixture to the flour mixture and stir with a wooden spoon just until a dough forms. Stir in the pecans.

3

Gather dough with lightly floured hands and transfer to a lightly floured surface. Roll the dough into a 2 x 8-inch log. Transfer the log to the baking sheet and shape into a log that is about 3/4 inch high and 2 inches wide.

4

Bake until firm to the touch, 20–25 minutes. Transfer the log to a cutting board and cool 5–7 minutes. With a serrated knife, cut into 12 (1/4-inch-thick) slices. Arrange the slices, cut-side down, on the baking sheet.

5

Reduce the oven temperature to 300°F. Bake the biscotti 10 minutes, then turn them over and bake until very dry and slightly crisp, about 10 minutes longer. Transfer the biscotti to a rack and cool completely. They will continue to dry out as they cool. Yields 1 biscotti per serving.
