From looking at the rules, it seems like you wouldn’t be able to call time since no batches of cookies leave an oven.
However, using a microwave could potentially be a faster way to reach the fully “baked” state, although this is only known to work on a couple cookies at a time. Although these cookies might not count as baked since they were never in an oven and microwaving the cookies would give them a rather mushy texture.
According to google cookies can also be made in a skillet/pan or in an air fryer, although the air fryer might count as a convection oven. An oven is still the best at cooking all the cookies at once, though.
Also I am not a mod do not trust me.
SRC has come up with an IRL section. All IRL cooking backing speedruns will commence there moving forward. Please follow the boards if you're interested in IRL cookie backing speedruns.
