This recipe is adapted slightly from MilkStore.com, and is for Milk Bar’s Famous Compost Cookie. The original called for 2 T Glucose, but I substituted 1 T Golden Syrup (you could use Light Corn syrup). Feel free substitute any kind of candy or sweet chips, such as toffee chips or peanut butter chips, for the sweet ingredients or any kind of salty snacks (popcorn or nuts) for the potato chips and pretzels.
The recipe produces a large, flat cookie with a crispy edge and a marvelously chewy middle. In my oven they took 14-16 minutes at 340F, rather than 18 min at 375F. So I recommend WATCHING them at around the 14 minute mark to see if they are just getting a pale golden ring around the edge while still being pale in the middle. That is the time to take them out. As they cool on the sheetpan, they will complete their baking.
I was able to make 18 cookies from this recipe.
