Cake Scale

About

Cake Scale — resize any baking recipe in seconds

Cooking for a different crowd? Cake Scale helps you adjust ingredient amounts when a recipe serves 4 but you need 6, 8, or just half a batch. No math, no guesswork, no account.

Open Cake Scale from Chrome’s side panel while you browse recipes online. Enter your original serving size, pick your new size, paste your ingredients, and get a scaled list instantly — right beside the page you’re reading.
