Unroll dough and separate into 8 triangles. Place 1 peanut butter cup in center of 1 triangle. Gently stretch corners closest to and farthest from cup together at top of cup, pinching edges together to seal around cup. Pull up third corner; firmly pinch edges to seal. Place on cookie sheet; twist 2 longest tips of dough to make ears. If desired, bend down longer ear. Repeat with remaining dough triangles and peanut butter cups, shaping and trimming dough as needed for desired shape.
