Preheat oven to 350ºF (177ºC). Line a large baking sheet with parchment paper or a silicone baking mat. Lightly flour the baking sheet. Set aside.
In a medium size bowl, whisk together butter, molasses, egg, vanilla extract, and brown sugar until combined. Set aside.
2 Tablespoons (28g) unsalted butter, 3 Tablespoons (60g) molasses, 1 large egg, 1 teaspoon vanilla extract, ½ cup (100g) packed brown sugar
In a large bowl, toss together the flour, baking powder, salt, and spices. Add the wet ingredients to the dry ingredients and gently mix with a large wooden spoon or sturdy rubber spatula until everything starts to come together. Mixture will be crumbly. This is ok. It will come together in the next step.
1 and ¾ cup + 1 Tablespoon (225g) all purpose flour, 1 teaspoon baking powder, ¼ teaspoon salt, ½ teaspoon ground cinnamon, ½ teaspoon ground ginger, ¼ teaspoon ground allspice, ⅛ teaspoon ground cloves, pinch of black pepper
Check out this Instagram reel to see how I make my biscotti. Turn dough out onto lightly floured baking sheet and, with floured hands, pat dough into a rectangle about ½" thick. My rectangle was 6" wide and 7 and ½" long (using a ruler or a ruled silicone baking mat is helpful here).
Bake dough slab for 20-22 minutes, or until the sides of the slab are lightly browned. The slab will be slightly cracked-- this is ok. Remove baked slab from the oven, but do not turn off the heat. Place baking sheet on a wire rack and allow to cool for 10 minutes.
Once the dough is cool enough to touch, cut into 1" thick slices using a sharp knife. Cut these 1" slices in half, making a perpendicular slice down the entire slab. Set slices cut sides up on the baking sheet.
Return to the oven to bake for 6 minutes. Remove from oven, turn biscotti over, and bake the other side for 6 minutes. Remove from the oven and allow to cool for 3 minutes on the baking sheet (cookies will become crunchy as they cool). Transfer biscotti to a wire rack to cool completely. Dust with powdered sugar, if desired, before serving. Biscotti stay fresh in an airtight container up to 2 weeks. Baked biscotti may be frozen up to 3 months.
