- 1/4 cup butter, softened
- 1/2 cup white sugar
- 1 egg
- 1/2 teaspoon vanilla extract
- 1 cup all-purpose flour
- 1/2 cup arrowroot flour
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- Preheat oven to 350 degrees F (175 degrees C). Grease baking sheets or line with parchment paper.
- Beat butter and sugar just until smooth. Beat in egg and vanilla.
- Combine flour, arrowroot flour, baking powder, and salt. Add to butter mixture and mix well. Divide dough in half.
- On a lightly floured surface, roll half the dough out 1/8 inch thick. Cut into 2 1/2-inch rounds. Transfer rounds to prepared baking sheet; prick with fork. Repeat with remaining dough.
- Bake in preheated oven until edges are golden brown, 8 to 10 minutes. Allow a bit more baking time if rolled thicker.
