Combine the flour, cinnamon, salt and baking powder in a separate bowl.
Add the dry ingredients to the wet and beat to combine.
Add the toasted almond slivers and beat until just conbined.
Line a baking sheet with parchment paper or butter the sheet.
Form into two logs about ¾ of an inch thick and as wide as you like your biscotti. I got for betweeen 3 and 4 inches. The wider it is the lest pieces you get in the end.
Bake for 35 minutes.
Take out and let cool enough for you to cut, 10-15 minutes.
Cut into slices about ½ inch thick.
Place slices cut side down on the cookie sheet.
Bake 12 minutes. Turn over and bake another 12 minutes.
