Line a heavy large baking sheet with parchment paper. Combine the flour and baking powder in a medium bowl to blend. Using an electric mixer, beat the sugar, butter, and salt in a large bowl to blend. Beat in the eggs 1 at a time. Add the flour mixture and beat just until blended. Stir in almonds and chocolate.
Form the dough into a 13-inch long, 3-inch wide log on the prepared baking sheet. Bake until light golden, about 40 minutes. Cool for 30 minutes.
Place the log on the cutting board. Using a sharp serrated knife, cut the log on a diagonal into ½ to ¾-inch-thick slices. Arrange the biscotti, cut side down, on the baking sheet. Bake the biscotti until they are pale golden, about 15 minutes. Transfer the biscotti to a rack and cool completely.
