Dessert Disaster

I bought this package at the Giant Tiger (think Walmart but Canadian, thus small, and pretty trashy/cheezy, but Cheap!).  I thought it would make a fun dessert.  I followed the directions carefully and this is what I got:


I think these issues may have contributed to the demise of the dessert:

1.  First time baking in a new-to-me oven. 

2. Light not working in oven.

3. Instructions specifically say bake until "center is still liquid" and the real trouble maker "do not open the oven during baking".

I even tried to rebake the remaining 2  cakes, but had the same results.  I am going to send the Dr.Oetker web site an email.  Maybe they will be helpful.
