I’d go half and if you wanted for the adults, just in case,pick up some cookies or cupcakes or other “overflow” dessert
We had about 35 people at my DD’s last bday party and got a half sheet from a different grocery store and it was plenty. |
Pp here - I just remembered I made a note on my calendar for this coming year and checked it. I wrote “reminder - half sheet for party (17 kids 12 adults) was plenty. Quarter sheet would have been fine” |
It will serve 36 2x3 servings. |
I’d say half, but you can also ask the bakery what they would recommend. I did this when debating between a full and half sheet and they steered me towards a half. We had more that enough cake for 40 people. |
In general, I think it actually serves close to double the recommended number. You are completely safe with the half sheet. |
