If you're familiar with making a mango float, that's basically what I did. I crushed the cookies and mixed them in the condensed milk and cream mixture. Also, I poured in a cup of water with some non-flavored gelatin mix. I didn't like the consistency at first because it came out runny. That's just a small setback when the finished product came out though.
I formed layers by alternating between the cream mixture and chocolate graham crackers. As you can see, I had to put small pieces of the grahams on the sides because the container I used was a little longer than the crackers. Before crushing the cookies, I took out their filling. At first, I didn't know what to do with them, but then I thought, why don't I use them as toppings?
After leaving it in the freezer overnight, it came out looking like ice cream. I don't have a name for it, really. Everyone who saw it thought it was ice cream at first glance. It was really sweet because I used up all of the contents of the condensed milk. I think I should've just used half a can or maybe I should've used more cream. Oh, well. At least everyone enjoyed eating it. I think this will suit you if you're into really sweet desserts or if you have all the ingredients at home and you're just as bored as I was when I made this.
