I have made this recipe a few dozen times and get requests for it all the time.
1/2 cup (1 stick) butter or margarine, softened
1/3 cup granulated sugar
1 large egg
2 cups all-purpose flour
1 teaspoon baking powder
1/4 teaspoon salt
1 cup white chocolate chips, melted
1 box (16 ounces) confectioners' sugar
Preparation Time: 45 minutes plus chilling
Baking Time: 6-8 minutes per batch
1. In a large bowl, using mixer set on high, beat butter and granulated sugar until light and fluffy; on medium speed, beat in egg. In a medium bowl, combine flour, baking powder and salt; add to butter mixture. Beat in melted white chocolate until thoroughly combined, about 1 minute. Form dough into a disk; wrap in plastic. Chill until slightly firm, about 15 minutes.
2. Preheat oven to 350 degrees F (180 C). Roll dough to a 1/4-inch thickness. Using cookie cutters, cut out shapes; place on ungreased baking sheets.
3. Bake cookies until lightly golden, 68 minutes. Let cookies cool completely.
