I keep being asked how to adapt a cake recipe to bake a larger or smaller cake. It’s not difficult and instructions are given in both my ‘Cakes to Inspire and Desire’ and ‘Celebrate with a cake!’ books! Below however is the chart you will need:
How to use the chart:
The chart assumes that your own basic recipe will be for a 20cm (8in) round cake, as this is the most common size. Therefore, if you want to make a 25.5cm (10in) round cake, for example, look at the chart and you will see that you need 11⁄2 times the quantity of your usual recipe.

If you wish to use a tin (pan) that is not mentioned above, such as a pre-formed shaped tin or oval, fill a 20cm (8in) tin with water and compare it with the quantity of water that your tin holds. The basic recipe quantity can then be multiplied or divided as necessary.
Hope this helps

hi Lindy I have a friend that wants me to make a cake for her baby shower, the cake is made in a 2 litre bowl and the recepie is a 5 egg maderia mixture my problem is my friend wants the chocolate cake in your inspire and desire book but i can’t work out what cake size to use, i thought maybe the 8 inch round and the mix that was left over i’d make some cup cakes, Would that be right or way too much? thanks so much Debbie xx
Hi Debbie
Yes I think that is what I’d do as well
Lindy
hi,
just a quick question. If i am making in a 28cm tine do I need to alter cooking time? recipe is for an 8” round tin, and bake at 140 degrees C for 40 mins-1 hour. Obviously I am making this by 2 1/2 so do i double up on cooking time or should it be the same!
Thanks,
Abbie
Hello Abbie
A 28cm cake is equivalent to an 11″. The baking times for this would be 1 3/4 – 2 hours at 180C.
thank you for being there.have just made a cake for my great
-gran daughter christening could not have done it with out your help.
Hi Lindy,
My Mum and I are going to make my wedding cake. I would like a madeira cake at the bottom, a lemon cake in the middle and a fruit cake on on top. Would a 12 inch, 9 inch and a 6 inch be big enough for 90 people? If not, what sizes would you use? Also, what quantities would you use and what temperature and for how long would you bake the cakes for?
Thank you,
Jessica
Hello Jessica,
I would suggest you look at Lindy’s Cakes to Inspire and Desire which contains recipes, portions and baking times. You can obtain this from our online shop.

Hi
I’m making a plain cake in a 12″ square tin but what temperature and how long do i bake it.
Thanks
You would need to bake a 12 inch square madeira cake for between 2 and a quarter and 2 and a half hours at 160 degrees Celcius (325 degrees Fahrenheit / Gas Mark 3).
HI,
If I have a wedding cake recipe for a 9″ fruit cake, how do I work out quantities for a 12″ and 6″ cake?
Hope you can help,
Dawn
Hello Dawn,
We tend to use an 8″ basic recipe as our starting point when adapting recipes.
If your start point was an 8″ fruit cake, you would need 2 1/2 times the ingredients for a 12″ cake and 1/2 the ingredients for a 6″ cake.
I hope this helps
hi i am going to try to make a two tier weeding cake i would like your advise on the right ingedients for a 35.5cm and a 23cm mudcake reciept i would be greatful for your help
Hi Sharon,
There is a mud cake recipe on Lindys blog.

Use this recipe with the chart above to work out how much mixture you will need for each cake
Hope this helps!
hi lindy ,
i am wanting to make an 10″ maderia cake , as your recpie is for an 8″ , i have read your instructions for changing the measurments, but i dont fully understand, it says times the quanty to 1 1/2 but what does that mean …. like if the butter is 12 oz make it 30 oz or does it mean make it 18 oz ??? if you could get back to me asap that would be great as i am making the cake tonight for a 40th wedding anniversary party ..
thank you
lora
Hi Lora
You times all the quanitities by 1.5, so 12oz becomes 18oz etc
Hope that is clearer
Lindy
Hi Lindy
I am due to make a 12 inch oval madeira this week and have been unable to find any recipe quantities for oval cakes – could you give me any advice? I used all of your tips re the perfect madeira with the last cake i made (except the glycerine as i couldn’t get hold of any) and i couldn’t believe how great the cake turned out! When baking an oval cake are there any other tips you could offer as i’m concerned that the assymetrical shape may result in uneven cooking. Thanks very much, Emma.
Hi Emma
To work out the amount of cake batter you will need, firstly measure the volume of the oval tin. Do this by filling the tin with water and then tipping this carefully into a measuring jug. Do this for a standard 8in tin or tin you know your recipe suits and then compare the volume and work out the appropriate multiple.
Hope that makes sense
Good luck
Lindy
I purchased one of your books a few months ago and say that the madeira cake turns out brilliantly everytime! I’m going to make a 14″ square madeira. Would you multiply the receipe by 4 for this size?
Hello Tracy,
We have lots of queries about changing cake recipes to suit a different sized cake tin. See our blog post on this subject for details of how to convert a recipe to the size that you would like.
hi lindy
for a 6in round, how would i do that , like do i half everthing or do i take 25% off .
thanks
lora
Hi Lora
You have to halve everything
