Beat together butter and sugar until very light and fluffy.

Blend in vanilla extract.

 Mix in flour and almonds.

Using about 1 Tbsp of dough for each, shape into logs and bend into crescents.

Place on greased cookie sheet. Bake 12 to 15 minutes at 350 degrees F until light brown.

While warm, roll crescents in confectioners' sugar. Cool on racks and store in a tightly sealed container.
