Maya Rudolph and Amy Poehler welcome new teams of home bakers to the cabin, starting things off with a bang by asking the bakers to recreate a cake that just exploded.
Maya and Amy challenge the bakers to create edible representations of their worst fears; the Panel of Opinionated Grannies tastes snakes, spiders, eyeballs and more to choose the winning Phobia Bake.
Maya and Amy pull vintage recipes from the Grannies' purses and ask the bakers to give their modern take on old-fashioned dishes that are as retro as they are revolting.
The bakers must decide if sweet or savory is better; Amy and Maya ask them to bake a pie that puts their best taste forward in the semi-finals; one team is eliminated, and the final four continue to the finals.
Amy and Maya ask the bakers to bake it to the limit in their final challenge; the teams create a centerpiece dish for their favorite holiday celebrations to impress the Grannies one last time and win the cash prize in the explosive season finale.
Hosts Maya Rudolph and Amy Poehler invite their famous friends to "cele-bake" the holidays in a friendly competition to raise some dough for their favorite charities.
