Biscotti: Beat, in a large bowl, sugar, oil, eggs and vanilla until combined. In a separate bowl, combine next 3 ingredients and gradually add to egg mixture. Beat until smooth. Add chocolate chips and almonds. Mix until combined.
Halve dough on a lightly floured surface. Shape each half into a log, approximately 14” x 2” (36 cm x 5 cm). Place on prepared baking sheet, leaving a 3” (7.6 cm) space between the 2 logs as the dough will spread.
Bake in preheated oven for 30 minutes or until lightly browned. Remove from oven and cool for 10 minutes.
Reduce oven to 300ºF (149ºC).
Slice each log on the diagonal, into ¾” (2 cm) slices. Place on parchment lined cookie sheets cut side up. Bake for 30 minutes, turning biscotti over after 15 minutes. Cool.
Drizzle: Using both chocolates together or separately, drizzle or dip biscotti with melted chocolates.
