Preheat oven to 350 degrees Fahrenheit.
Cream butter and sugar well with an electric mixer. Add sour cream, well-beaten eggs, and anise seeds, mixing between each ingredient.
In a separate bowl, mix flour, baking soda, and baking powder.
Add dry ingredients to wet ingredients and mix until the dough is sticky (do not add more flour).
Grease one cookie sheet with butter.
Divide the dough into 3 loaves. Wet fingers very lightly to shape dough without it sticking to your hands. Put all 3 loaves in one pan.
Bake for 35 minutes. Remove from the pan and let cool on a cooling rack.
Slice into ¾” slices at an angle.
Lay sliced biscotti on a cookie sheet and bake for 15 minutes until brown, then turn over and bake for another 4.
Serve dipped in chocolate or dunk in coffee if you so desire. Enjoy!
