Chocolate Cake and Margarita's!

My brother in laws birthday is coming up next weekend and I volunteered to make the cake.  As soon as I saw this cake posted over at Thy Hand Hath Provide I knew I had to make it.   The directions were a bit long, but not complicated.  I did a trial run this Sat night when my mother was visiting.  oh my- one margarita and a piece of this cake turned us into comatose blobs!  I HIGHLY recommend this cake!
