My immediate thoughts are to use the following ingredients:
Almond Flour, Sugar, Salt, Baking Soda, Applesauce, Vegetable Oil, Vanilla Extract, and chocolate Chips.
Almond flour is safe to eat raw (as opposed to regular flour which isn't), as are applesauce vs. eggs. This has two advantages- avoiding opportunities for food borne illnesses, and not cracking/mixing eggs.
Vegetable oil is easier than melting butter. It may lead to a greasy cookie, but it also won't stick to any parchment paper as badly.
Further, it is, in my opinion, ill advised to use measuring tools. Your hands can approximate cups, 1/2 cups and the like. Pouring applesauce and vegetable oil can be done by eye (carefully, but quickly). Mix by hand in a single bowl would have to be the fastest method.
As for baking, to avoid burning yourself it might be wise to preheat a cookie pan on top of an oven as opposed to inside it. The pans won't be cold and suck heat in when warming, thus (if I'm not crazy), leading to slightly faster baking time.
But, uh, this is all untested conjecture. Saw this category on Reddit and wanted to throw in my $0.02.
Actually, there might be two other takers for 100skill any%. I posted my idea for a route on the discord, you might give it a try.
If you can get your (any% sun) ending run down to 26 minutes I'll run (100 skill any%).
The discord is dead for this game and it took like 11 days for a Speedrun to be verified.
I realize I'm 5 months late but here goes: Watch the record console run and the record PC run, and maybe a few others. Take notes of what they do, what works, and what doesn't. Read the documentation for running, there's an Excel file in the guides section. Also consider joining the discord.
Running on console will have different tricks and tips than PC, for instance in handling the goethermal plant. On switch, you'll need to kill some robots before routing power away from Edgewater because they'll be agro'd. On PC they sneak out and back on to reset robot agression because loading screen times are removed, but that doesn't work.
Basically, watch the runs, and then copy them. Innovate if you see something done in a less-than-optimal way, but in general copying the top runs will give you a solid base.
I've been playing Tradewinds Legends. My first speedrun of that game (where I was still figuring out the game- there are no tutorials for speedrunning so I had to figure things out on my own) was pretty abysmal. I cut my time in half so far and am pretty sure there is still room to reduce it further.
I'm not sure if this is a game that would be worth a leaderboard, but Tradewinds Legends has been the first game I've wanted to speedrun. I'd recommend people give it a shot- it's got a few laughs in it.
