Steps

Melt the butter over LOW heat, then the marshmallows, stirring until just smooth. High heat makes hard candy of them — low and slow keeps treats soft.
Off the heat: vanilla, salt, then the cereal, folded until coated.
Press into a buttered pan with a buttered spatula, using the least force you can get away with. Compacted treats are dense treats.
Set 30 minutes at room temperature. Cut into 12 squares and hide some.

How scores work

Computed on the finished dish, not an average of the parts: 1796 kcal goes into the pot, 479 g of ingredients comes out as ~470 g of food → 382 kcal per 100 g. Cooking moves water, and energy density is the score's biggest lever — so we show the math. Full formula here.
