Cookie Exchange Calculator

Cookie swaps work on a simple contract: each guest brings a fixed number of dozen of one recipe, and everyone leaves with variety. Multiply guests by dozens each to size your bake — the host often bakes the same rule as attendees.

One dozen per guest is the classic swap — 12 guests means 12 dozen total in the room if everyone participates equally, but you only bake your assigned dozens, not the full room total. Enter dozens each as your personal obligation.

Example: 10 guests each bringing 1 dozen → you bake 10 dozen (120 cookies) of your chosen recipe if you are one of ten — confirm party rules; some hosts ask for 2–3 dozen per family regardless of headcount.

Batch baking across days freezes well — slice logs and drop cookies freeze unbaked or baked. Label allergens (nuts, gluten) on swap plates.

Plate presentation counts — uniform size helps fairness when guests pick one of each type. Shipping tins for office swaps use the same dozen math with smaller per-person counts.

Pair with pie and hot chocolate calculators when hosting a dessert-heavy open house the same weekend as the swap.

Recipe scaling: double batches carefully — leavening and pan crowding may need adjustment on very large trays beyond this guest-count tool.
