Here are the coconut macaroon "best practices":
Do Macaroons Need to be Refrigerated?
If you're planning on eating your macaroons within a couple of days, then no, they don't need to be kept cold. They should be just fine if you leave them out on the counter in an airtight container. They'll definitely soften up a little bit, but they'll be perfectly delicious.
If you're planning on eating your macaroons within 2 weeks, then definitely go ahead and keep your coconut macaroons in the refrigerator. That will help them retain moisture so they don't dry out.
Can You Freeze Coconut Macaroons?
If you're planning on rationing your macaroons so that you always have a gluten free treat on hand whenever you want it, by all means freeze your coconut macaroons! Macaroons freeze really well, so you don't have to worry about anything happening to them while they're in the freezer. Give them about an hour to come up to temp before eating them, or, if you're the frozen candy bar type, try them frozen!
