This sounds more like a frozen mouse than a candy, per-say. The frame is a form which fits into the half sheet to raise the sides. I'd just divide the mixture into brownie pans. The Knox gelatin is 7 grams per package, I'd dump it in a little pile, take a sharp knife and guesstimate. (Pull the shades down first, LOL) The glucose is what we know as simple syrup. Nothing more than a concentrated sugar water. Great for sweetening cold drinks. Don't want to make it? Find it at your local package store, or in the cake section of Michaels, Hobby, Lobby, A.C. Moore, Jo Ann's, etc. I'm not a cake person, but I think those same stores may have half sheet frames, or a restaurant supply. LIS - I'd use brownie pans. Any one who is in the catering business may really like this. For Me and He, way too much trouble. However, the concept is mouth watering, & I'll modify it to suit my own needs, say, using a packaged flan mix.
Let's see - the crust - not much different than a graham cracker crust, using peanut butter with the crushed cereal and adding melted chocolate chips;

Use a packaged flan mix or
Mix egg yokes (this recipe calls for almost 7, my batch would be smaller)with the cream, a touch of vanilla extract, a pinch of gelatin dissolved in warm water, a pinch of sea salt, and caramel ice cream topping. Whip, pour,and freeze. Add nuts if desired.
Complicated simplified.
