Famous as large (this recipe originally made 4 inch diameter cookies) delicatessan treats.
These are a favorite of mine...they remind me of 'Lorna Doones'.
This recipe was all over the internet as 'Insanely Easy Two Ingredient Ice Cream Bread', but made as a loaf cake.
I prefer to use a mini-muffin tin and use them as finger food or on a cookie tray.
You can use ANY flavor of ice cream. Vanilla* works, but specialites like 'Samoa' or 'Mint Chocolate Chip' are really good.
