1 c  Butter, softened
     1 c  Packed brown sugar
     1 c  Smooth peanut butter
     1    Egg
     1 ts Vanilla
     2 c  All-pupose flour
     1 ts Baking soda
   1/2 ts Salt
FILLING
     6 oz Semisweet chocolate chips
     1 ts Butter
 In large bowl, beat butter until fluffy; gradually beat in sugar until
 light and fluffy. Beat in peanut butter, egg and vanilla until smooth.
 Combine flour, baking soda and salt; gradually mix half into peanut butter
 mixture. Using hands, mix in remaining flour mixture to form stiff dough;
 refrigerate for 45 minutes.
 Filling: Meanwhile, melt chocolate with butter in bowl over hot (not
 boiling) water. Let cool.
 Divide dough in half. On lightly floured surface, roll each half into
 10×8-inch rectangle. Spread each rectangle with half of the chocolate
 mixture.
 Starting from the long side, roll up each rectangle jelly-roll style to
 form 2 long rolls. Wrap separately, seam side down, in plastic wrap.
 Refrigerate until firm, at least 8 hours or up to 12 hours.
 Using sharp knife, cut into 1/4-inch thick slices. Place 1-1/2 inch apart
 on lightly greased baking sheets. Bake in 375F 190C oven for 10-12 minutes
 or until lightly browned.
 Transfer to rack; let cool. (Can be stored in airtight container for up to
 1 week.)
