Question About Credit Card

I use a cash-back credit card, which offers 2% cash back on groceries, 3% back on gas, and 1% back on everything else. I do a lot of charitable giving via credit card (to a variety of nonprofits), and that all falls into that 1% category. Can someone direct me to a credit card that would offer more than 1% cash back for charitable giving? (I have excellent credit, so I should qualify for just about any card.)
Please include a link to where I can apply online, and include any personal experience you have with the card you're recommending and/or with getting cash back from charitable giving via credit card.
Thanks!
