The system, which consists of a plug-in warmer unit, together with frozen cookies, is already being trialled in selected Balfour stores, as well as foodservice outlets. It will be launched officially at the beginning of next month.
Nestlé said the units, which cost £199 each, would pay for themselves in 19 days if 30 cookies at 75p were sold a day.
The cookies supplied are Nestlé Toll House the leading US cookie brand. Three chocolate chip variants will be available initially, but others are planned for later in the year.
The brand launched into the US retail arena more than 70 years ago before extending into foodservice.
A Nestlé spokesman said the company had not ruled out moving it into retail in the UK.
