Next combine the sugar, flour, baking powder, salt, butter, vanilla, and eggs. Mix this well.
Then, fold in the white chocolate chips.
At this point on a greased baking dish, I make 2 logs out of the dough. These can be about 8" long x 4" wide, or the size you prefer. I also flatten them down a bit; however, they do not rise much so be sure and keep that in mind.
Bake these for 30 minutes, until the dough sets.
Remove from oven and using knife, cut diagonally. At this point, you simply want to make the impression. You do not need to separate them entirely, but this makes it easier to cut them when they are completely done.
Once you have done this, place back in the oven at 275* for 20 minutes.
Let them cool and use a knife to separate them.
Once they are cool, melt the chocolate per the package instructions. Dip each piece in the melted chocolate, then dip in the crushed candy canes. Place on parchment paper and let harden. Continue this with all biscotti.
Makes about 12-16 biscotti depending on the size of the pieces.
According to the original recipe these last for up to 2 weeks in an airtight container, at my house they barely last a few days because we eat them all!
