<P> The Frosty is the signature frozen dairy dessert of Wendy 's fast - food restaurants , introduced in 1969 when the first restaurant opened . The Frosty 's original light chocolate flavor , actually a combination of chocolate and vanilla , was initially the only flavor offered . Wendy 's founder Dave Thomas thought that a pure chocolate flavor would overwhelm the taste of the restaurant 's hamburgers . In August 2006 , a vanilla flavor was introduced after repeated consumer requests . </P>
