Preheat oven to 325°.
Grease a large baking sheet or line with parchment paper.
Combine flour, anise, almonds, butter and baking powder in a medium bowl.
In a separate bowl, beat the egg and sugar until light and fluffy.
Add vanilla to egg mixture.
Add the dry ingredients, and mix well.
Divide dough into 2 equal pieces and roll each into a 12 inch log.
Place 4-5 inches apart on the baking sheet and bake for 20-25 minutes or until firm.
Remove from oven and cool slightly.
When cool, cut logs diagonally into 1/2 inch slices.
Place slices on baking sheet 1/2 inch apart and return to oven for 10 minutes or until lightly browned.
