pistachio lime shortbread sandwich cookies {#BakeForACure}

My very favorite food blogger, Joanne Bruno of Eats Well With Others, asked me and a bunch of other food bloggers to join her in a cookie fund raising project for cancer research.

Each of us are making a batch of delicious cookies and offering them for sale, highest bidder takes the batch.

Mine are these refreshing shortbread cookies with lime filling. Perfect for a spring picnic, if you don't eat them all out of the box.

Check out the yummy treats up for bid on her website: Bake to Cure Cancer.

Bidding starts Monday, April 21 and ends Wednesday, April 23.

Have your sweets and put your money toward a good cause at the same time. Can't beat that!
