This is one of my favorite, favorite cookie recipes ever! Danish Vanilla Slices. They taste like fresh, delicious bites of vanilla. Plus? Since you have to form the dough into logs and freeze it, you don't have to sit there baking all day. You can slice off 3, 14, or 25 and just bake those. I like to bake half and keep the other log in the freezer for emergencies.

Danish Vanilla Slices (from TheGreat Scandinavian Baking Book by Beatrice Ojakangas)

1 cup butter, room temperature
3/4 cup sugar
1 egg
3 cups all-purpose flour
1 teaspoon baking powder
2 teaspoons vanilla extract
powdered sugar

Cream butter and sugar. Add egg. In separate bowl, mix flour and baking powder. Add to butter mixture, alternating with the vanilla. Mix until stiff dough forms. Knead lightly. Divide into 2 parts, form into logs and wrap in plastic wrap. Chill one hour. (If you plan to store for longer, wrap in wax paper and foil, freeze up to 2 weeks).
Cover baking sheets with parchment paper. Slice dough into 1/4 inch slices and bake for 10-12 minutes until golden. Allow to cool, dust with powdered sugar.
