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?

A. Measure out 1.5 tablespoons lightly beaten egg

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.

What is the equation for the scaling function? ›

The graph y=k⋅f(x) (where k is a real number) is similar to the graph y=f(x), but each point's distance from the x-axis is multiplied by k. A similar thing happens when we graph y=f(k⋅x), only now the distance from the y-axis changes. These operations are called "scaling."

How do I downsize a recipe? ›

The trick is to switch your measurements to units that are simpler to split, such as tablespoons and teaspoons. Key Measurement Conversions for Scaling Down Recipes: 1 cup = 16 tablespoons (tbsp) = 48 teaspoons (tsp) Half of 1 cup = 8 tablespoons = 24 teaspoons.

What is scaling equation? ›

Scaling equations are often developed to generalize results from limited data sets. The form of the equations is usually based on physical intuition about hydraulics, guided by the techniques of dimensional analysis and statistical model fitting (eg, O'Connor et al., 2006).
