Packed with peanuts in three forms--peanut butter, peanut powder, and chopped peanut brittle--and spread with chocolate, these are the ultimate peanut butter cookies. Peanut butter lovers, these are the best peanut butter cookies you'll ever eat. Sometimes called black bottom cookies because of the chocolate spread on their backs, they're a decadent and delicious cookie recipe. A classic, times 3! #peanutbuttercookies #blackbottomcookies #pastrychefonline
