Cookie Exchange RSVP Website: Dozens, Allergens, and a Baker Count

A cookie exchange fails on arithmetic. If twelve bakers each bring twelve dozen, every baker goes home with twelve dozen cookies. If a thirteenth baker walks in with a tray because they heard about it that morning, your stacks are wrong, your table is short on space, and someone who baked for the published number has to split a dozen in the parking lot. The RSVP is the baker list. The cookies come after.

You can create a cookie exchange RSVP that caps bakers, asks what they are baking, and records allergens before anyone buys butter. A group text that says "I'll bring something" is not a dozen and it is not a label.

Lock the number, then tell people the dozen count

Pick the baker cap from the table you have and the amount you want people to carry home. Six bakers is a manageable afternoon. Twelve is a lot of tins and a lot of sampling. Twenty is a drop-off, not a party, unless you have the space and you have said so. Publish the cap and the formula in the first paragraph: "Eight bakers. Each baker brings eight dozen of one cookie. Each baker leaves with one dozen from each baker, including their own."

Do not invite "plus whoever wants to bake." Extra bakers change the multiply for everyone who already shopped. If you want non-bakers in the house to drink coffee while the swap happens, say they are guests and they do not add a dozen and they do not take a dozen unless you have built extras into the number. Most exchanges should not do that. Sampling from the display plate is not the same as a take-home share.

This is closer to a dish-signup list than to a holiday headcount, with one difference: every person brings the same quantity of a different cookie, and the quantity depends on how many people said yes. You cannot tell anyone "bring two dozen" until the yes list is closed, or you have to publish a fixed dozen count and turn away bakers after you hit it. Fixed count is easier. Close the list, then send the number. Do not change it.

Allergens have to be on the tin, and on the RSVP first

Ask each baker to name the cookie and check every allergen that is in it or in the kitchen where it was made: peanut, tree nut, egg, dairy, wheat, soy, sesame. "May contain" belongs on the form if they baked it on a shared counter. A guess at the party is how someone who cannot eat nuts takes a linzer that looked plain.

If you are running a nut-free exchange, say nut-free in the title of the page, not in a footnote. That means no nuts in the dough and no nuts in the kitchen that day. Bakers who cannot promise that should sit this one out. Collect allergy severity for anyone who is eating, including a guest who is not baking, so you know whether a separate table is a preference or a medical line you cannot cross.

Require a label on every container: cookie name, baker name, allergens. The RSVP should show an example of that label so people do not arrive with a pretty tin and a story. Labels written at your house, from memory, get the flour and the nuts mixed up.

What "one kind" means

One baker, one cookie. Assorted boxes look generous and make the split impossible, because you cannot give every other baker the same dozen. If someone wants to bring an extra sampler for the table, that is a gift to the coffee pot, not a second entry in the exchange. Say whether bakery cookies are allowed. A swap that is about homemade should say homemade. A swap that allows a good bakery box should say that too, so the person who rolled dough at midnight is not surprised.

Containers, drop-off, and the no-show

Tell bakers to bring cookies already divided into dozens, in containers they can give away, or in tins they are willing to lose. A single roasting pan of cookies that still needs to be counted will hold up the whole table. If you want the containers back, you are running a different event. Say "disposable, or labeled if you must have the platter returned before you leave."

Publish a drop-off window. Cookies that arrive after the swap has started do not fit the piles. A baker who cancels the day before changes the dozen count for everyone else. Put a cancel-by time on the page, and decide in advance what you will do: drop the dozen number by one and text the group, or keep the number and you bake the missing dozen. Both are fair. Silence is not.

If the exchange is one hour inside a bigger party, do not mix the lists. People who are coming to dinner and not baking belong on the holiday party RSVP. People who are baking belong here, with the dozen math. One form that asks both "are you coming" and "are you baking eight dozen" will get you dinner guests who think a sleeve of store cookies counts.

A cookie exchange RSVP is finished when the baker count is frozen, every baker has named the cookie and the allergens, and every person knows how many dozens to bring and what time the piles get made. Turn the oven on after that, not before.
