Hey there! I know I am a tad late to this, but have been working on this clone for a while with the help of another mixer named Dannick on ELR. He is the one that realized OOO Speckled Flakes is one of the main components, and I added that Graham Cracker Clear is also a proponent. My recipe has gone through several revisions, and I found Tres Leche may also be in it as well. My latest recipe is missing a complex cream type flavor, I am thinking a condensed milk, or condensed caramel milk. Once you start with Speckled Flakes, you can build the recipe from there, but it is the main component, that one flavor that tastes so hard to nail down. How he found it is beyond me, but I suspect Food Fighter is also using a powdered sugar concentrate and a creamy condensed milk type flavor from OOO as well. Hope this helps!
