Bringing food through US Customs

We’re flying from Dublin so will do US customs in Dublin in preclearance. I know you can’t bring fresh fruit but can you bring fruit in baked goods, so things like banana bread or banana muffins? I’m 99% sure I brought sweet potato and blueberry pancakes before.

My 2 year old is allergic to milk and Aer Lingus don’t offer a milk allergy food option. I’ve ordered him the kids meal and a vegan meal for me so he can hopefully have one of those but the kids one will probably have milk and he’s 2 so depending on what the vegan meal is there may be zero chance of him eating it. Was going to bring him a peanut butter sandwich but then there’s the risk of someone with a peanut allergy. At home he only really snacks on fresh fruit which we can’t bring or things like homemade muffins, so the options for food for him for a 9 hour flight are pretty limited so really hoping banana muffins are ok!
