Hello!
Great question! Depending on the size of your cheesecake, this could be a great option! I would recommend placing your cheesecake on a cake board and not directly on the box itself alone. I would worry the moisture from your cheesecake would soak through the box and may not look the prettiest.
Personally, I've used this box myself to hold a cheesecake and it worked perfectly, but remember you can always try a sample to test out to see how well this box would work for you before ordering a larger quantity.
Have a wonderful weekend.
