Grandma's Cookies is a Thrilling Horror Comedy that for years, a seemingly sweet and devoted grandmother has baked her way into the absolute trust of her grandchildren, ensuring they come over every single weekend for milk, cookies, and warmth. But behind the gentle, folksy facade lies a deeply deranged, calculating human being playing a horrific long game. Her years of nurturing were merely a meticulous countdown; Grandma has been grooming the children since infancy, waiting for the exact moment they hit their teenage years to execute them. When the grandkids finally stumble upon the terrifying truth that their beloved matriarch is a cold-blooded serial killer, the cozy suburban kitchen transforms into a desperate, visceral battleground for survival. Stripped of their innocence, the teenagers must weaponize every brutal, low-blow tactic they can muster to shatter Grandma's control, stun their predator, and escape her house of horrors alive.
