Meringue Cake Failure

Lately we have been going low-carb.  But I have a SUPER sweet tooth, so this has been very difficult.  After 2 weeks I needed SOMETHING sweet.  The latest Martha Stuart magazine had some great recipes in it and with a little modification, are very low carb.  I attempted to make this beautiful meringue cake.

I put it in the oven and started on the syrup.

I took it out of the oven and this is what it looked like.

Oops.  I think a couple things went wrong.  First I used one of those rubbery bunt pans and put it in a water bath.  I should have skipped the water bath using that pan.  The second, I think I actually over mixed the meringue.  It had stiff glossy peaks but it had only been about a minute and the instructions said 3-4 minutes.  Lastly, I used splenda instead of sugar (no carbs in splenda).

We did try it then chuncked it in the trash.  Maybe next time.
