Chocolate Birthday Cake Calculator

For those times that you need chocolate cake but you can’t find a tin the right size in your cupboard.

Skip to the calculator… round cake or square/rectangular cake

For those times that you need chocolate cake but you can't find a tin the right size in your cupboard.

It seems that there’s a lot of love around for my Chocolate Birthday Cake Recipe and I’ve started to get requests for the quantities to make it in various different shapes and sizes. So far each time I’ve been asked I’ve tapped away in excel to work out what’s needed, but I thought it was about time I sorted out a calculator (just like my vanilla birthday cake calculator) so you can do it yourselves without waiting for me.

All you need to do is to enter your tin dimensions and the number of layers you’d like the cake to have into the boxes and it’ll tell you what you need. I hope you all find it useful…

As with the vanilla version, I've not tested the cake in all possible sizes but as long as you don't stray too far from the original quantities it should still work well.

Chocolate Cake FAQs

What temperature should I cook the cake at?

You can cook the cake at the same temperature given in the original recipe regardless of the size of tin you're using.

How long should I bake my cake for

As long as you split the mixture into layers the cooking times will be the same as in the original recipe.

Can I cook my cake in one deep tin instead of sandwich tins?

Yes, however it will take longer to cook.

If you cook the mixture for two layers in one deep tin it will take 45-50 minutes to bake rather than the 30-35 specified in the original recipe.

I only know my tin size in inches. How can I change it to cm to use the calculator?

To convert from inches to cm, simply multiply by 2.5

Can I use this recipe to make cupcakes

Yes, I've turned this recipe into a cupcake recipe here.
