This recipe comes from some recipe booklet my mom bought in the check out line one day. I can't even tell you the name because the cover has been ripped off. What I can tell you is that they made my favorite cookies list.
3/4 c Chunky Peanut Butter
1/2 c butter, softened
1 c packed light brown sugar
1/2 t baking powder
1/2 t baking soda
1 1/2 t vanilla
1 1/4 c all-purpose flour
2 c quartered miniature peanut butter cups
1/3 c milk chocolate chips
1 small plastic bag
Beat peanut butter and butter in large bowl of electric mixer at medium speed until well blended. Beat in sugar, baking powder and baking soda until well blended. Beat in egg and vanilla until well blended. Beat in flour at low speed just until mixed. Stir in peanut butter cups. Cover and refrigerate 1 hour or until firm.
Preheat oven to 375 degrees. Form 1/4 cup dough into a 1/4-inch-thick disc.
Place dough on ungreased baking sheet. Bake 10 minutes or until lightly browned. Remove to wire racks; cool completely.
Place chocolate in small resealable plastic freezer bag; seal bag. Microwave at MEDIUM 2 minutes, turning bag once. Knead bag until chocolate is smooth. Cut off tiny corner of bag; pipe chocolate onto cookies. Let stand until chocolate is set.
