Yes, absolutely, you can still donate those items.
Now, having said that. If you can tie a string around your finger and remember to pre-check for the future, that would be very helpful. Pre-checking your donation is a real courtesy to your hub manager. It makes easy work for them to submit the final counts on donation Sunday. Here is a reminder of our pre-check process.
When you pre-check your donation, it is automatically listed on a printed sheet, placed on a clipboard, and you can simply scribble your initials and dash. No paper bag with your name is needed. Further, it is much easier for a hub leader to estimate the number of bins/boxes to put out. Rest assured, even if your count changes between the pre-check and the physical donation, as when a spouse unexpectedly cuts into one of the loaves, you can easily make a note on the printed check-in sheet.
Baking and donating is wonderful. Baking, pre-checking, and donating is divine!
