Muffet may be spared by waiting or consuming a spider item (which may be bought at the Ruins). She does not fight if an item was bought at the Spider Bake Sale in Hotland and if the protagonist is on the Neutral or True Pacifist route.
The seasonal treat is a yeast doughnut with orange frosting and topped with a chocolate glazed Munchkins doughnut hole “that mimics a spider, complete with chocolate drizzle for spider legs and white drizzle forming the eyes.”
In the Ruins, Spider Donuts can be bought for 7G each and Spider Ciders for 18G each. In Hotland, Spider Donuts and Spider Ciders can be bought for 9999G each.
If you have to SPARE Muffet manually (because you couldn't afford the Donut or the Cider), you need to wait long enough (17 turns) until Muffet receives a telegram from the spiders in the Ruins who will explain that you are not evil to spiders. Here are some pointers for the Muffet fight if you need to wait her out.
Muffet will mention that the protagonist donated, but she will still be suspicious of them and attacks. If she is spared, the Genocide Route will be aborted. Once she is spared, Muffet does not appear again as an NPC.
The easiest way to beat Muffet is to buy a Spider Donut (or Spider Cider) in the Ruins and then keep it with you until her fight. If you eat it during her battle, she'll realize that you don't actually hate spiders, and end the battle early.
