T.F.
I freeze a lot of things like that and it always comes out great. We have a pie shop who has a buy one get one on the mini pies and I take advantage of those.
I have frozen buttermilk, key lime, apple and they did great.
I also take advantage of Nothing Bundt Cakes and the Buy one Get one and those freeze very well.
I buy the "single serve" mini pie or bundtlet for myself and they last about 3-4 days for me after I thaw them.
