Cookie exchange for a large group: how many cookies each?

Most cookie exchange guides picture a living room. What's Cooking America says to "plan the cookie swap for 10 to 12 people", and its example for eight attendees is "9 dozen cookies from the same recipe" per person. With 25 or more guests those formulas stop working. This page shows why, then two ways to keep a big swap bakeable. The counts come from the same code as the swap page.

30 guests, a dozen of each kind
360 cookies each
That is 30 dozen per baker, and 10,800 cookies on the table.

Why a dozen per guest breaks at 25 or more

If every baker makes a dozen for each guest, the work grows with the headcount. At 8 guests that is 8 dozen (What's Cooking America adds one more dozen to share at the party; this page counts only the dozen per guest). At 30 it is 30 dozen, about 15 batches of two dozen from one person. Every guest then leaves with 360 cookies in 30 kinds.

The other rule of thumb scales the same way. Two Twenty One says it is "best to plan on everyone taking at least 5 cookies of each cookie home". With 30 kinds that is 5 x 30 = 150 cookies to take home, and each baker still makes enough of one kind for 30 people, from a rule that gives 40 cookies in its 8-person example. A rule written for a small group has to change when the group is not small.

Two ways to shrink it

Cap the take-home per kind. Everyone takes 4 or 6 of each kind, however many kinds there are. Each tray is emptied by small portions, and everyone still leaves with a full assortment.

Split into tables. Divide the guests into tables of up to 10. Each table swaps only inside itself, with a dozen per table guest. The work depends on the table size. The cost is variety: a guest sees 10 kinds instead of 30.

Cookies per baker, by number of guests

Guests means everyone who bakes, you included. Each cell is the number of cookies one baker makes. For the table approach, the group is divided into the fewest tables of 10 or fewer, as evenly as possible.

Cookies one baker makes in a large cookie exchange, by guest count and approach
Guests Dozen of each kind Cap: 6 per kind Cap: 4 per kind Tables Table swap, a dozen each
20 240 120 80 2 x 10 120
25 300 150 100 3 x 9 (about) 108
30 360 180 120 3 x 10 120
40 480 240 160 4 x 10 120

The cap columns assume each guest takes the stated number of every kind, their own included. A cap of 4 gives a guest 120 cookies at 30 guests, in 30 kinds. For the dozen rule at smaller sizes, see the chart for 4 to 20 guests.

Worked example: 30 guests

  1. Dozen of each kind: every baker makes 360 cookies. That is too much for one or two evenings.
  2. Cap of 6 per kind: every baker makes 180 cookies, 15 dozen. Each guest takes home 180 cookies in 30 kinds. A heavy bake, possible over a weekend.
  3. Cap of 4 per kind: every baker makes 120 cookies, 10 dozen, and each guest takes home 120 in 30 kinds.
  4. 3 tables of 10: every baker makes 120 cookies at a dozen per table guest, or 60 at a half dozen. Each guest leaves with that many cookies in 10 kinds.

A cap of 4 and a table swap at a dozen ask for the same baking (120 cookies). What differs is the box: 30 small samples or 10 full dozens. My suggestion: pick the cap when variety is the point of the party, and tables when guests want enough of one cookie to share at home.

When to run two swaps instead

My suggestion: past about 30 guests, run two swaps on different days. A table with 30 plates is hard to walk, the labels take longer to read than the cookies take to eat, and early guests leave before late ones arrive. Two swaps of 20 keep the cap at 6 to 8 per kind. It also gives people a second date if they miss the first. This is a judgment call, and the table above holds either way.

Set it up here

Create the swap with a cap per kind and the form works out the baking. Each guest claims one cookie with a nickname, the page blocks doubles so 30 people do not bring six batches of the same thing, and you can print labels and a cookie list. The link opens the form set to 30 guests and 4 of each kind. For tables, make one swap per table.
