Bake Sale Thank You Card, what to write?

[ProudNavyWife827]

On Friday I hosted a Bake Sale at My Job, which turned out very successful and I wanted to write out Thank You Cards to everyone who donated bake goods. I wasn't sure if I should specify in each card what they exactly donated. I'm just stumped on what to say...I just want to make it short and sweet...What should I write in my Thank You Cards??????? Please HeLp!
Thanks for your Suggestions! They helped a lot!
