How to Scale Any Recipe to Make it a Small Batch Recipe · i am a food blog (2024)

If you’re anything like me, you like scaling recipes. It’s one of the magic things about baking: everything is infinitely scaleable. You should, in theory, be able to make one cookie or 100 cookies all taste exactly the same using the magic of math. So if you want to learn how to scale recipes for small batches, you’ve come to the right place.

Plus in the time of Covid, when you don’t have a lot of ingredients (I’m looking at you butter, flour, and eggs!) scaling recipes just seems like the smart thing to do. You can avoid going to the grocery store more than necessary and still have a huge variety of things to make and eat. Most small batch recipes out there are for baking, since baked goods always seem to be for 2 dozen or more, but I find the following tips and tricks good for scaling cooking recipes too since we just have two of us at home . I’m forever googling: how much is half of 3/4 cup. Now, for my sanity, I will have all the conversions right here on one page.

How to Scale Recipes for Small Batches

If your recipe comes in weights (yay British baking sites!) and you use a scale, you’re in luck. All you need to do is punch everything into a calculator and divide by 2 if you’re halving or 4 if you’re quartering. But, if your recipe is in cups and tablespoons, sometimes there’s a bit more to figure out. You could use one of those online recipe converters. But if you do, you’ll probably end up with a bunch of strange fractions like 7/8 cup or 1/16 teaspoon. I know because I use them all the time andI am forever googling things like:

  • what is half of 3/4 cup
  • how do you measure 1/6 cup in tablespoons
  • how do you measure out half an egg
  • how many tablespoons are there in 1/6 cup

Online recipe converters are helpful because they do most of the math for you, but I’m always double checking. So, here are some things that I find really useful when scaling recipes.

Converting Cups to Tablespoons
If you’re small batching baking, you’ll inevitably run into weird cup measures like 5/8 or 3/8. Don’t bother trying to use your cup measures, instead, just check how many tablespoons you need.

1 cup = 16 tablespoons
7/8 cup = 3/4 cup + 2 tablespoons
3/4 cup = 12 tablespoons
2/3 cup = 10 tablespoons + 2 teaspoons
5/8 cup = 1/2 cup + 2 tablespoons
1/2 cup = 8 tablespoons
3/8 cup = 1/4 cup + 2 tablespoons
1/3 cup = 5 tablespoons + 1 teaspoon
1/6 cup = 2 tablespoons + 2 teaspoons
1/4 cup = 4 tablespoons
1/8 cup = 2 tablespoons

Eggs – How Do I Measure Out Half an Egg or Partial Eggs?
Almost all baked goods call for eggs and usually more than one. Most likely if you’re small batching a recipe you’ll get 1/2 egg. Don’t despair. You don’t have to go looking for tiny eggs. It’s super simple to halve an egg.

How to Measure Half a Large Egg
Lightly whisk your large in in a small bowl, being sure to incorporate the white with the yolk then either:

A. Measure out 1.5 tablespoons lightly beaten egg
B. Weigh out 26-28 grams lightly beaten egg

How to Measure One Third of a Large Egg
Lightly whisk your large in in a small bowl, being sure to incorporate the white with the yolk then either:

A. Measure out 1 tablespoon lightly beaten egg
B. Weigh out 18-19 grams lightly beaten egg

How to Measure a Quarter of a Large Egg
Lightly whisk your large in in a small bowl, being sure to incorporate the white with the yolk then either:

A. Measure out 2 1/4 teaspoons lightly beaten egg
B. Weigh out about13-14 grams lightly beaten egg

What Do I Do With My Extra Egg?
You can save it in the fridge, in a container to use in another small batch recipe or scramble it up.

What Else You Need to Consider:

Sizes/Pan Size
If you’re small batching cookies, just make the cookies the same size as what the recipe calls for. With a small batch, you’ll just end up with less cookies. For cake/bread you’ll need to adjust the pan size, sizing down accordingly unless you want a flatter cake or loaf. Generally, you can use a regular loaf pan for sheet pan cakes that you want to small batch. For loaves/quick breads, half a recipe should usually fit into a mini loaf.

Temperature
This one’s easy, just keep the temperature the same!

Baking Time
For cookies, the baking time will remain the same. For cakes and loaves, they generally take a little less time, so subtract 10-15 minutes off the time and start taking peeks into your oven (without opening the oven door). When the cake/loaf is has risen and is suitably browned, double check with a skewer in the middle (it should come out clean). Make a note of how long it took you to bake so that next time you’ll know exactly how many minutes your mini cake took.

FAQs

How do you scale down a recipe formula? ›

Scaling a 10-portion recipe down to six portions involves two steps:
  1. Divide 6 by 10, which gives you a conversion factor of 0.6.
  2. Multiply each ingredient amount by 0.6.

How do you scale up a recipe for production? ›

How To Scale Up A Recipe: 4 Easy Steps
  1. Step 1: Determine the Conversion Factor for the Recipe. ...
  2. Step 2: Convert all Weights in the Recipe to Ounces and all Volumes to Fluid Ounces. ...
  3. Step 3: Multiply Each Ingredient in the Recipe by the Conversion Factor. ...
  4. Step 4: Simplify and Round the Numbers for Easier Recipe Use.

Can all recipes be scaled up or down? ›

Scaling down usually works fine to a certain extent, but not always. This is especially evident if your recipe/formula is done with volumetric measurements (e.g. cups, tsp, tablespoons), but even if your recipe is by weight, linear scaling up usually will lead to over seasoning.

How do you determine the scaling factor for a recipe? ›

Example: The 100% ingredient in the Mac and Cheese recipe above is white cheddar cheese. Calculate the scaling factor by dividing the number of servings (or grams) you want to make by the recipe yield. Example: This recipe yields five servings. If you are making nine servings, the scaling factor is 9 ÷ 5 = 1.8.

What is the two fold process for scaling a recipe for non multiple servings? ›

Explain the two-fold process for scaling a recipe for non-multiple servings. Divide each ingredient amount by the number of people the original standardised recipe serves and write down what the 'per person' measure is • Multiply the 'per person' measure for each ingredient by the number of people you need to serve.

Which types of recipes might not scale well? ›

Recipes such as baked goods with leavening ingredients such as baking soda, baking powder, and yeast don't lend themselves to scaling as easily. You can't simply add double the amount of baking soda in your bread dough and expect it to come out well.

How are most recipes scaled measured? ›

Recipe scaling is not just a matter of multiplying the ingredients. The container size and its shape (surface area to volume) cooking methods, and the accuracy of your measurements all greatly influence recipe scaling. Measuring all ingredients by weight will give you the most accurate results.

Why does doubling a recipe not work? ›

Here are some reasons why simply doubling a recipe might not always work: Irregular scaling of ingredients. It's a truth well-known to experienced cooks that ingredients don't always scale in a linear fashion. Doubling spices, for example, could overwhelm the dish.

What is the one big rule in baking? ›

Never bake without measuring your ingredients. Unlike cooking, baking is first a science, then anything else. If you start adding ingredients like baking powder and sugar without measuring, it can lead to some spectacular baking disasters.

How do you change the number of servings in a recipe? ›

Keep It Simple. The easiest way to modify a recipe is to double it or halve it. Keep your eye out for recipes that serve either twice or half as many people as you're cooking for.

What is the formula for scaling? ›

The basic formula that is used for calculating the scale factor is, Scale factor = Dimension of the new shape ÷ Dimension of the original shape. In case, if the original figure is scaled up, the formula is written as, Scale factor = Larger figure dimensions ÷ Smaller figure dimensions.

What is the first step in scaling ingredients? ›

You first have to find the scale factor. If the recipe makes 24 cupcakes but you want to make 100, divide 100/24, and you get approximately 4.2 times scale factor. (Always round up so you will have to many instead of too few!) So if the original recipe calls for 1 cup of milk, use 4.2 cups of milk.

What is the first step to find the conversion factor when scaling a recipe? ›

Determine the required yield of the recipe by multiplying the new number of portions and the new size of each portion. Find the conversion factor by dividing the required yield (Step 2) by the recipe yield (Step 1). That is, conversion factor = (required yield)/(recipe yield).

What steps should be followed to decrease the size of a recipe? ›

It's basically arithmetic. If the recipe makes say eight servings, and you want just two servings, each ingredient should be divided by four. So if it starts with 2 pounds of ground beef, Divide that by four and get 1/2 pound of ground beef. If it says one cup of flour, you would use 1/4 cup of flour.
