This mix allowed my little one to have cupcakes at his second birthday party.  They turned out great and with some homemade vanilla icing, they were a hit with everyone!  I even used Ener G's egg replacer to replace the multiple eggs the mix calls for.  One hint, bake for almost the maximum time on the directions.  They come out golden brown and moist.

Ex Input:
I don't like this product at all.  Much tastier and cheaper to just use hot water and a packet of hot chocolate mix from Nestle or Swiss Miss.

When I bought my Keurig brewer, I eagerly looked for other beverage options for my wife who is not a coffee drinker.  I'm still looking.  The Grove Square Hot Cocoa had a nasty aftertaste, almost metallic.  No amount of cleaning/tinkering with the brewer made any improvement.  I used the brewer to make hot water for a Nestle Hot Cocoa pack, and that was a far superior beverage.  The Grove Square quickly found it's way to the trash.  I'll find quality mixes and use the Keurig to heat the water from now on.
