I've done a fair share of cheesecake in the past. Now I would like to try this Japanese cheesecake for an upcoming birthday. We'll be around 20 persons, but the recipe is for an 8" round pan, which is not enough. Can-I double the ingredient and put it in a 10" square springform pan? Do-I need to cook it longer?

  • When in doubt, make more cakes.

It's really hard to say, there are many factors to consider: oven size and power, the recipe ingredients, pan size and shape, etc. The recipe calls for an 8" or 9" round pan, I will use an 8" pan in calculations. The main question is area, an 8" pan's area is 50 square inches (that's pi times the radius squared), while the area of a 10 x 10 springform pan is 100 square inches, double that of the 8" pan. Your cheesecake will actually be the same thickness as the pan the recipe calls for, so the the baking time is not going to be dramatically different. It will be a bit longer because the cake area is bigger, that could be just a few extra minutes. Keep in mind that recipes can often be way off in baking times. Other Japanese Cheesecake recipes call for baking an hour, not 30 minutes, for example.

The recipe does not say how to check your cake is done, which is not good. Baking times vary according to many factors, and you should always bake for a result using time as a guideline. Most recipes say to bake until it's a golden brown as your first guideline, given it's actually a souffle I'd use the touch test, ie push it down with a finger, if it springs back up it's done.

My advice would be to make this recipe smaller scale before doubling it, make sure you get the ins and outs right before you make it for dinner guests.

  • That's strange, I see 8" or 9" pan in the recipe. Where do-you see 7"? Sep 13, 2017 at 17:49
  • It's the first line of the method, it says a 7 inch pan.

  • Are you talking about "Line the base of a 7″ round cake pan(fixed base) with parchment paper and grease the sides with butter, set aside." ? That's in a review, not the specific recipe. Sep 13, 2017 at 18:19
  • I have to admit to being confused @VincentCrete, the comment is more prominent than the actual recipe itself as the link you posted redirects to a different page and you have to click through for the actual recipe. I will edit

I can't vouch for any of this since this is the first time I've heard of this cheesecake style but if it's cooked in a water bath, there should be fairly little risk of it cooking unevenly because of the larger size. (I did make a bunch of different cheesecakes with that method and they usually turned out well.) Use a thermometer to check for doneness, and make sure to leave ample time for it to cool and set.
