These are a standard houseparty offering that always seem to go down well. It is an adaptation from from the back of a packet of Reese’s peanut butter chips, but don’t let that put you off — despite being a Hershey’s product it is really rather good. Unfortunately the peanut butter chips need to be hand imported (as pretentious people would say) from the US (unless anyone knows where I can buy them here in the UK? Here’s hoping…). White chocolate chips substitute just fine though.
