Julia's Biscotti

This comes from my beloved mother in law.   This biscotti will last for a week easily, if you don't eat it all first. It has only lasted more than a few days in my house because it was misplaced. INGREDIENTS 1/2 c butter 2 T olive oil 3 egg yolks 3 eggs 1 1/2 c sugar ( I prefer the rich flavor of raw sugar) 1 T anise seed 1/2 T vanilla 1/2 t almond extract ( if almond is not a good option try anise extract instead) 5 c flour 5 t baking powder  3/4 t salt DIRECTIONS 1)  preheat oven to 375 2)  melt butter and cool by adding olive oil 3)  beat eggs until soft and foamy 4)  mix sugar into eggs until thickened and lemon color 5)  mix in oil butter mixture then slowly add anise seed, vanilla and almond extract 6)  sift together flour, baking powder and salt then mix into wet ingredients in about 3 additions 7)  divide dough into half and like cookie sheet with parchment paper 8)  form two long, flat bars the length of the cookie sheet and bake for 20 minutes 9)  cut each bar crossways into 16 cookies and lay on cut sides then bake for 10 more minutes 10)  cool and serve
