The Cookie Swap Batch Planner

It earns its place when the swap wants six dozen or more, your recipe makes far fewer than that, and you are doing the shop and the bake on the same weekend.

Multiplying a cookie recipe by five is the easy part. This works out the whole batches, turns them into a shopping list in the packs the shop actually sells, tells you what a cookie costs you, and counts bake day backwards from the time you want to be finished.

The Scale Up tab. Each ingredient is multiplied out to five whole batches, then converted into whole shop packs with the cost of each and what will be left over. Below it, the Setup tab reports five batches, 120 cookies, $66.56 and 55 cents a cookie.

Nobody scales a recipe badly. They scale it in the aisle

The invitation says nine dozen. Your recipe says twenty-four cookies and two and a quarter cups of flour. Somewhere between those two numbers is a shopping trip, and most people do that arithmetic standing in front of the butter with a phone in one hand. So you buy four blocks when you needed three, miss the second bag of chocolate chips entirely, and come home with a tub of baking soda to sit beside the one you already had. Then you find out at four in the afternoon that five oven loads and two hours of chilling do not fit into the evening you set aside. None of it is difficult. It is just three sums that have to happen in the right order, before you leave the house.

Three sums, done before you leave the house

Three sums, done before you leave the house

How many cookies you actually owe, how many whole batches that takes, and how many spare you end up holding. Always rounded up, because half a batch with two eggs in it is guesswork. Every ingredient multiplied out, minus what is already in the cupboard, divided into whole packs. Three blocks of butter, five bags of chips, and no second tub of baking soda. Mixing time, the fridge window, and every oven load to the minute — counted backwards from the moment you want the last tray out. Plus how many boxes to fill.

It costs what it costs, and the sheet says so

Packs to buy, multiplied by what each pack costs on the shelf, ignoring everything you already own. Divided by the cookies you end up with, that is the price of one cookie. The example recipe lands at fifty-five cents, and most of it is butter, vanilla and chocolate. You may decide that is fine. You may decide to swap the chips for something cheaper, or to lower the extra dozen. What you will not do is find out afterwards. It counts whole packs, so a nine dollar bottle of vanilla is charged at nine dollars even though you use a tenth of it. Everything you keep shows up in the left over column.

What's inside

Start Here
The order to do things in, and one honest paragraph about why a swap is not free cookies.
Setup
Bakers, dozen owed, tasting table, spare, your recipe yield, oven load size, mixing minutes, chill time, and the time you want to finish. The batch maths and the cost per cookie sit underneath.
My Recipe
Up to 20 ingredients. Amount per batch in your own units, what one shop pack holds, what that pack is called, what it costs, and what is already in the cupboard.
Scale Up
Every ingredient multiplied out to whole batches, with still-to-buy, whole packs, the cost of each, and what will be left over. Cupboard staples turn green and drop off the list.
Shopping List
A printable list in the units the shop sells, with a tick column and a running total — and a separate list of what you already own, so you do not buy it twice.
Bake Day
Mixing, the fridge window, and every oven load to the minute, counted back from your finish time. Plus boxes to fill, cookies in each, and what to write on the label.

Who this is not for

If you are bringing two dozen to a swap of four people, you do not need this. One batch, no arithmetic, go and enjoy your afternoon.

It handles one recipe per copy of the file. If you are baking three different cookies you will want three copies, and the totals will not add themselves together. We would rather say that here than let you find out after you have paid.

It earns its place when the swap wants six dozen or more, your recipe makes far fewer than that, and you are doing the shop and the bake on the same weekend.

Before you buy

Do I need to pay for Google Sheets?
No. Google Sheets is free with any Google account. If you would rather use Excel, that file is in the same download.
My recipe is in grams, not cups.
Use grams. Nothing is converted behind your back — the sheet only needs the pack size written in the same unit as the recipe amount. A kilo bag of flour is 1000 grams and that is all it needs to know.
Does it scale the baking time as well?
No, and nothing should. A tray of cookies takes the same time whether it is your first or your fifth. What changes is how many trays, and that is what Bake Day counts.
Can I use it for more than one recipe?
One recipe per copy of the file. Save a second copy for the second recipe. The shopping totals will not add themselves together, which is honest of them.
Why is the cost higher than I expected?
Because it counts whole packs. A nine dollar bottle of vanilla is charged at nine dollars even though you use a tenth of it. Everything you keep shows up in the left over column.
How many ingredients does it handle?
Twenty. If your cookie needs more than twenty ingredients it is not a cookie, it is a project.
What if it does not work for me?
Email us within 14 days and we refund it. You keep the file. We would rather have the feedback than the nine dollars.

★★★★Denise

Good planner. The shopping list that falls out of the scaled quantities is the bit I would pay for on its own.

★★★★★Holly A.

My recipe makes twenty-two cookies and the swap wanted six dozen. I have got that scaling wrong in both directions before. The batch maths here just works, including the odd-number-of-eggs problem.
