I have a great chocolate cake recipe that actually tells me the weight of each ingredient to add to the size of each cake, from square to round, from 6" right up to 12" in size

So I want to use that recipe for cupcakes
But how many cupcakes can I get out of - say for example, a 9" mix?

depends on the size of cupcakes.

In general, a cake mix (i.e. makes two 8" rounds or two 9" rounds, according to the box) will make 24 regular size cupcakes.

I just made mini cupcakes for the grandkids tonight and got 72 mini's out of one cake mix (with a bit of batter leftover that I just pitched.)

Yep to what Indydeb said. It depends on how much batter you put in each cup. When in Doubt, make a double batch and freeze the rest you don't need right away.

It's actually not from a packet. It's a written recipe that gives me variations of the weights according to square/round and from 6" right up to 12"

Also curious for quoting purposes so I know how much money I'm actually making...

If you are baking in the muffin sized papers (38mm in height), use a standard sized ice-cream scoop with swiper blade and you will get 24.

Using a standard mix and a standard sized muffin tin (filled about 1/2 full) you'll get 24.

Even with the type of recipe you have where you can get the batter by weight, it will still depend on how much batter you use.

I weigh my cupcakes when i make them. Depending on the recipe i use any where to 50 grams to 65 grams. It is not a constant for some reason. So if you do the math and divide the batter by the number of cupcakes you desite, you will find out how much batter you will have for each cupcake. The Cake Bible recommends 45 grams per cupcake which i found was not enough.

I agree it is important to know how many cupcakes you can get out a certain amount of batter. That is why i spents weeks making cupcakes in various weights til i achieved the size cupcake i wanted. I still highly recommend making some batter and doing a test run. If you make 12 ounces of batter and then start with 1 ounce per cupcake and go from ther, then you will know with your recipe how much you need and what looks like a good size cupcake.

And it will be easier to use grams than ounce, at least in my opinion.

I think I will do a practice run first.

Now I have to try work out how much mix I need for 150 cupcakes!
