BonJour Frother, Manual Caffe Froth Maximus, Brushed Stainless SteelGloria Jeans Butter Toffee K-Cup, for the Keurig brewing systems offers a pleasantly tasty aroma that fills the kitchen upon brewing. The taste is good, but not as Heathbar-like as I would prefer. It has that toffee flavoring to it but I've found to really enhance the satisfication with this flavor go and froth yourself some milk and pour butterscotch syrup all over it. Yummy.
Keurig offers a stainless steel frother, which does a very good job and cleanup is simple too. Link above review.
