Who doesn't love potato chips? Here they add a salty crunch to butter cookies.
Combine butter and the 1 cup powdered sugar in a large mixing bowl; beat with an electric mixer on medium speed for 3 minutes. Add egg yolk and vanilla and beat until well mixed. Gradually beat in flour. Stir in potato chips and pecans with a wooden spoon.
Drop by rounded teaspoons onto a greased cookie sheet. Bake in a 350 degree F oven for 10 minutes. Transfer to a wire rack. While cookies are still warm, sift with powdered sugar. Cool completely. Store in airtight containers. Makes 40 cookies.
Freeze baked cookies in a freezer container up to 1 month.
