Overall, it's a no-bake dish, even though you do have to prep some of its components on the stove top. I think that it took me about an hour to do completely prep. (This was the second time around...the first time I got 90% of the way done with it and realized that I had forgotten to add the sugar to the custard! It was a big time bummer, let me tell you...so make sure that you read all of the directions and add all of the ingredients.)
I let it sit in the fridge for a good 6 hours before I broke down and finally got a piece, but it probably could have stayed in for a little bit longer. Don't get me wrong--the crackers were definitely soft, but they weren't as cake-like as they were later on after they had been sitting for longer.
This dessert was so good that I never got any really legit pictures of it! I was at work on Monday eating the last piece in silent gratitude when I had that "oh crap!" moment and snapped a few last-minute pictures on my phone before it was completely gone. So that's why it's sitting in a tupperware container on top of my lovely faux-wood desk ;)
