Ingredients
6 tablespoons butter2/3 cup sugar1/4 teaspoon salt1 to 2 teaspoons vanilla extract1-1/2 teaspoons baking powder2 eggs2 cups King Arthur Unbleached All-Purpose Flour
Preparation
In a large bowl, cream butter, sugar, salt, vanilla and baking powder. Beat in eggs (the batter may look slightly curdled). On low speed, add flour; mix well. Dough will be sticky.
Grease a baking sheet or line a baking sheet with parchment paper. Place the dough on the prepared sheet and shape into a 14-in. x 2-1/2-in. x 3/4-in. log. Bake at 350° for 25 minutes.
Remove from the oven and reduce heat to 325°. Cool log on baking sheet for 10 minutes. Using a spray bottle filled with room-temperature water, lightly but thoroughly spritz the log. Cool 5 additional minutes. Transfer to a cutting board; cut with a serrated knife at a 45° angle into even 1/2-in. to 3/4-in. thick slices.
Place the biscotti on edge on the prepared baking pan. Bake for 25-30 minutes or until biscotti feel dry on the edges and begin to turn golden brown. Remove to wire rack to cool.
