Babs3466 - Your Question:
I love using this. The only problems I have is it only works with round and square tins and it doesn't tell you the new baking times.

Our Response:
Have you tried the Cakeometer App? if you've a smartphone or tablet this will help you with cooking times etc.

Great App - and FREE as well! Thank you. As to people stressing in the comments about loosing info and needing a log in - the App is FREE! Of course the mathmatical calculations will not round up and down for you, it is an exact science. If you use your common sense, as long as you round all ingredients up or down, you should be fine. Another idea would be to add info, and work it out from the eggs. So say your new ingredients are 4.7 eggs - and it was 2 before. Round down to 4 eggs and then you can see you just need to double everything OR round up to 5 eggs, get your orig quantity of 2 eggs, divide everything by 2 then x by 5. For a FREE App, I am happy to let all my students know how well this works. Thank you :)

Can't get this to work - just coming up with "infinity" against ingredients Help!

After changing to a new phone and downloading both my cakeometer and cakeulator apps from my iCloud I've lost all my recipes,previous quotes and additional ingredients from both and it's not the first time it's happened. I then spent ages rewriting and re-adding them all,only to have to reset my phone to resolve an issue(unrelated),so I've lost everything again! I love the apps but my patience is wearing thin-surely in this day and age there must be a way to combat this?! Even a simple login option which would also allow you to use the apps on multiple devices?

I LOVE this app!! I make lots of cakes, tiered or otherwise and it never fails me.If you have ingredients missing then it's probably because you have entered a 1/2 or a 1/4 which it doesn't recognise... just pop in .5 or .25 instead.Some people have asked about cooking times... well, you can't have everything and I think common sense needs to be put into use! If it's smaller then just check it sooner, or leave longer if it's bigger and don't increase the temperature!!Another fab app is Cake Stacker... if you bake for a living don't leave home without it!Calculates everything from tier shapes, previews and gives you dowel, ribbon and fondant quantities!

The cake converter worked a dream, many thanks for this.I had also hoped to be advised of the time difference in different size tins, but could not find this information unfortunately.Can you help please?

BUDDY - 3-Oct-13 @ 7:55 PM
It hasn't worked for me!!I have typed in all ingredients and the different tin sizes but nothing has happened!Do I have to do anything else?
Mavis52 - 28-Sep-13 @ 4:36 PM
Ok so I got all the ingredients, but how do I know how long to cook the cake for?The description says that it includes cooking times, but where?Please help!!
Kaz - 23-Sep-13 @ 2:51 PM
I may be doing something wrong here, I wrote down all the ingredients for 6 inch cake pan and in the conversion I get all the ingredients except the flour.Why!!

I am so happy as I have converted a 12" to 10" chocolate tier for my daughter's wedding cake. I was a bit worried up to now. Thank you so much
Charlie - 29-Aug-13 @ 3:08 PM
This is just awesome the days of me trying to work it out myself are now history, brilliant idea thanks you thank you. Off to start my twin daughters three tier game of thrones 18th birthday cake, using the tins I already had thus saving myself cash on buying new ones.
Carol - 25-Aug-13 @ 11:10 AM
Hi there found this brilliant for my needs, my sister wants me to make her wedding cake as its going to be a 4 tier this has worked a treat but I was wondering if you could help me with the cooking times aswell as im not to sure about that if possible I recently did a 6" x 6" x 3" trial of madeira cake and that took around 1hr 50mins at gas mark 4 im going to be doing a 8x8 10x10 and 12x12 if you could help me with this I would be so grateful thank you
malcy - 20-Aug-13 @ 10:31 PM
this seems so easy - thanks - when I got my quantities, converting from small round to large square amounts seemed enormous then noticed original rounds were for two separate cakes so just halved the amounts given - haven't tried yet but seems to be about right.
postie - 4-Aug-13 @ 6:35 AM
Could you give me a guide to convert round tin sizes to the equivalent square tin. Many thanks, Polly
Polly - 28-Jul-13 @ 3:04 PM
Yes, love the app but no cooking times shown.I am now trying to convert from 2 sandwich tins as I don't want to include a filling but want to make one large cake.Can you help?
Alex - 26-Jul-13 @ 11:32 AM

bellevueace - 25-Jul-13 @ 7:24 PM

angie - 23-Jul-13 @ 8:10 PM
hiya, im making a chocolate cake and have no problems with entering the ingredients, it seems like an excellent app. i am only confused at the bottom where it states new recipe. is this the extra amount i add to my existing recipe? It surely cant be the new recipe? your comments would greatly help before i make a kitchen disaster! ha! : )
angie - 23-Jul-13 @ 7:38 PM
I think this calculator will be fantastic for allowing me to scale up a Christmas cake recipe to 3 tiers for a wedding cake. However, like many of your previous customers, I am wondering whether you just round up or down the fractions of grammes, teaspoons , mls and whole eggs to make it practical for weighing and measuring the new recipe ingredients? I presume the tolerances are such, especially in a fruit cake, that it won't make much difference to the finished results.I am wondering now about cooking times for the larger cakes.Thanks.
CW - 18-Jul-13 @ 12:52 PM
It doesn't ask but what if the original recipe makes 2 or 3 cakes? Most recipes don't just make one 8 or 9 inch round cake but may make 2 or 3. How do I account for that when trying to convert to a different size pan?
N - 18-Jul-13 @ 2:28 AM
Hi! What happened to this app? I can't find it in the AppStore anymore. :(
chocydolly - 15-Jul-13 @ 6:54 AM
I have just been on your cakeometer and love but have a query! It has converted an 8inch round cake to a 10inch round cake but some of the ingredients are odd like for the 10inch it says to use 4.7 eggs is it best to use 5 or 4 1/2 some of the other ingredients are odd too so do you suggest to round up or down.Thank you for your help
Aggie - 30-Jun-13 @ 7:24 PM
Hii most really be doing something wrong. Put every thing in plus the cake tin size from 6inch to 8inch nothing happens am i ment to click on something else.
buddy - 18-Jun-13 @ 7:48 PM
Hi...I was trying to figure out how much time it took to convert a coconut cake recipe into cupcakes and it did not work for me.Maybe I have too many ingredients? Thanks for any info you can give me:)
Amy - 1-Jun-13 @ 5:37 PM
The CakeOmeter was excellent scaling up from on 8" to 10" cake tin. However the most important part was the cooking TIME , but there was no mention of how long to cook the cake !I saw a comment about turning the cake halfway thru the normal cooking cycle however as far as I know one cannot open the oven during te cake cooking process ..hence I still don't know how long to cook this chocolate cake !HELP !
Mary - 27-May-13 @ 8:10 PM
@Buddy. We've just checked this and it definitely works. Just add your ingredients then put 6 inches in the existing tin space and 8 inches in the new tin space. You new recipe shows at the bottom.
CakeBaker - 20-May-13 @ 11:52 AM
