Preheat the oven to 350F. Line a large baking sheet with parchment paper and set aside. Combine all the dry ingredients (All-Purpose Flour, White Granulated Sugar, Baking Powder, Salt, Ground Anise, Whole Anise Seed) in a medium sized bowl and whisk to combine.
Add the eggs, oil and vanilla extract and mix until combined.
Turn the biscotti dough onto the lined baking sheet and, using your hands, combine and shape into an oval/rectangle about one inch thick. Bake for 30 minutes until lightly browned. Let it cool for at least 15 minutes before cutting into.
Slice the biscotti about 1-1 ½ inches thick and place side by side, cut side up and bake for 12 minutes. Remove from the oven, flip over, and bake for 10 more minutes until browned
Transfer to a wire rack to cool completely. Good for one week in an airtight container.
