Have you ever wondered how to calculate cake recipes for odd shaped cake tins? This is a question I often get asked. Knowing how to calculate the quantity of batter for non-round and non-square cake tins will enable you to bake cakes in odd shaped tins and molds without any wastage.
This is the technique I used when I baked a 3D car cake in a car shaped cake tin. And I use the same technique for all my other cakes which are baked in non round and non square cake pans.
This is an easy technique so long as you have a cake recipe that you have baked before and know how much batter it will produce for a certain cake tin size.

❤️Why you will love this tutorial
- It helps you bake cakes in any shape.
- It reduces wastage at having to guess the amount of batter required for a specialty cake tins.
- You can also use this technique to scale up or down the size of round cakes and squares cakes.

🧾Supplies required
This is what I use in this tutorial to calculate and come up with the estimation for the cake batter:
- 6 inch round cake tin (I have baked six inch round cakes many time and know how much batter the tin would require)
- Water - this is used as a substitute for the cake batter when calculating the estimate.
- A large measuring cup
- The actual cake tin or pan you intend to bake your cake in.
💡How it works
Note: In order for this technique to work, you must know how much batter you cake recipe yields for a standard round or square tin.
For example, if the recipe you have is for a 6 inch round cake, you will need to know much will the cake batter fill the 6 inch cake tin, i.e., whether it will fill half of the tin or two thirds of it. Only if you know this will this calculation technique work.
Assuming your recipe normally fills two thirds of a 6 inch round tin, you will need to fill the cake tin with water until it is two thirds full. Then, pour the water into a measuring jug. Note the measurement.
In my example, two thirds of my 6 inch cake pan fills 800 ml water. So, this is how much batter my recipe will yield. If my odd shaped cake pan requires more than 800 ml batter, I will have to scale up my recipe accordingly.
Let's assume I wish to bake a dome shaped cake in a bowl shaped cake tin. To determine how much batter my dome-shaped tin requires, I fill it with water all the way until it is about ¾ inches to the rim. This is how much I want the cake batter to fill my cake tin. I then pour the water into a large measuring cup. In my example here, the dome-shaped bowl requires almost 1000 ml batter. This is more than the 800 ml for a 6 inch round tin. So I will have to scale up my recipe in order to have enough batter to fill my dome-shaped bowl.
👩🍳How to Calculate
To calculate how much scaling is required, you can use this formula:
- Batter for odd shaped cake tin (in ml) / Batter for standard round or square tin (in ml) = number of times the recipes needs to be scaled up or down
I have illustrated this in graphics below.
The Scenario
Assuming the recipe you have is a butter pound cake recipe for a 6 inch round cake tin. You have baked this cake before and know that the batter (before baking) will fill up to two thirds of the cake tin.
You now want to bake the cake in bowl shaped tin and need to know how much you need to scale the recipe (up or down).
Step 1: Fill the round cake tin with water
Fill your 6 inch round cake tin with water until it is two thirds full (two thirds because that is how much batter your recipe normally produces and you know it).
Note: You will only be able to use this technique this if you remember the point at which your cake tin is filled with the cake batter based on your experience of baking the cake previously.
Step 2: Measure the water in the round tin
Pour the water from the cake tin into a large measuring cup and note the measurement. In this example it is 800ml.
Step 3: Fill and measure the water in the bowl shaped tin
Repeat the same process with your bowl shaped cake tin. Fill it with water up to the level where you want my cake batter to fill up.
And then pour the water into a large measuring cup and note its measurement. In this example, the bowl requires 1000 ml batter.
Step 4: Calculate the batter required with the formula
Based on the measures above, here is the formula to calculate the required amount of cake batter for the odd shaped cake pan:
- Batter for odd shaped cake tin (in ml) / Batter for standard round or square tin (in ml) = number of times the recipes needs to be scaled up or down.
Using this formula in the example above, the equation to calculate would be as follows:
- 1000 ml / 800 ml = 1.25 times
This means you will need to scale your recipe by 1.25 times from the original recipe which was meant for a 6 inch tin. To do this, each ingredient in the calculated recipe for a 6 inch round cake tin must be multiplied by 1.25 times. This way I will have the required amount of cake batter for the dome-shaped bowl.
And that's it. This is how I calculate cake recipes for odd shaped cake tins and pans.
I hope this will be able to help you to calculate cake recipes for your baking projects!

Hi, I'm not understanding the formula stuff. I waqnt to make a Victoria sponge in my new air fryer using 2 x 5" Springform tins and I want to know what the quantities are for the ingredients please
Thank you

Hi Alan,
In order to be able to calculate the quantities required, you would need to have a base measurement. Have you made the cake in any other cake tin sizes pls. If not, you wont be able to use the formula.
