These were the biggest hit at our KY derby party! They are rather rich, so I recommend cutting them into smaller bites (approx 1.5"x2.5" seemed about right). Also, I found the shortbread dough was not quite enough to cover the bottom of my 9x13 brownie pan, so I opted to use slightly smaller pyrex dish.
This picture makes me irrationally angry. Why would you use cutouts instead of just cutting the whole thing into pieces!?!?
