This pound cake comes out buttery and tart, and the graham cracker crust crumble adds just the right crunchy surprise!

I love exploring farmers markets and trying out new recipes for parties - especially my annual derby party. We recently visited a nearby market, which inspired the peach scones from last week, but for my recent key lime obsession, we had to go a little further afield... but after creative recipes for key lime pie cookies and key lime pound cake, it was worth it. The hardest part will be deciding which to serve for my next Kentucky Derby Fete.
