Preheat oven to 170 C / Gas 3. Grease a baking tray or line with parchment paper.
In a large bowl, cream together butter and sugar until fluffy. Beat in eggs, vanilla and Amaretto. In a separate bowl mix flour, baking powder and salt. Stir flour mixture into butter mixture. Fold in nuts and white chocolate chips.
Divide dough into 4 equal parts. Place each 1/4 of dough on baking tray and form into logs about 35cm long and 3.75cm wide.
Bake 25 minutes in the preheated oven, until very lightly brown. Cool and cut diagonally into 1cm slices. Arrange slices on baking tray and continue baking 8 minutes, until golden brown.
Once cool, dip the bottom half of each biscotti into dark chocolate. Allow to set on greaseproof paper.
If you like the traditional harder and dryer biscotti, make the second bake time a little longer.
This mix tasted wonderful however, it was a very sloppy dough, I added quite a bit more flour.. I bake lots of biscotti and this tasted just fine. It may need a little tweaking though. Thanks for sharing! 👏🏻 - 29 Nov 2015
