Slice frozen cookie roll in 9 slices, then cut each in 4 parts. Roll each in a ball and place in ungreased muffin tin or paper cups (on a cookie sheet). Bake as directed on package 8 to 10 minutes, until golden brown. Place a peanut butter cup in center of warm cookie and press down. Remove when cool. Makes 36 cookies. If you use paper cup, just leave in cup (colored ones are nice for a party).
