Chocolate Chip Cake

This is the first time I have tried this recipe. I made it for my husbands birthday. It looks impressive, if you can see past my bad photography, tastes very rich and is simpler than it looks.  I believe I had two or three requests to "Make this for my next birthday."

Notes: The batter is more like cookie dough when done and subsequently the cake is more cookie-like. This makes it easier to assemble. Make sure your chocolate is completely melted or you get little choc bits like I did. I did not have a 15x10 pan that I trusted to bake in anymore (I don't know why I keep it around still) so I used a regular larger cookie sheet. this resulted in 5 layers for me. I cut 4 across the pan then cut some off each end to make a 5th layer. Probably for this reason I needed more frosting than the recipe made. Slice it thin, it is very rich or sweet.  Even age14, aka. the bottomless pit, said "I'm full."   Do not leave out on counter where you will be tempted to have a piece every time you pass it.
