So I tried freezing cakes for the first time a few days ago. I baked as I usually do, waited about 10 minutes, took cakes out of pan, wrapped securely in saran wrap (with no openings), then wrapped in foil. I put them on the top shelf in my freezer and took them out today. After 3 hours I checked and saw that one of them was pretty mushy on the bottom from condensation.
Does anyone know how to prevent this?
Thanks!!!

Did you defrost on the counter? I always put my cakes on cooling racks and haven't had that happen.

My cakes are cooled before being wrapped and put into the freezer. Putting anything hot/warm into the freezer raises the temp inside the freezer. That's when bacteria can grow.

Try letting them cool completely. There will be less moisture trapped due to the hot air still inside of the cake.

I cover the cakes in waxed paper when I take them out of the pan and let them cool completely. Then I double wrap them in plastic wrap and freeze. They thaw on the counter top. Usually turn out great.

I did cool them on a counter...and it was only mushy on the bottom so that makes sense. I was torn, but I've read posts where people swear by wrapping them hot. I'm doing another 'freezing' experiment tonight and I'll try letting it cool completely first then putting it on a rack.

I read where people wrap them hot also, but it's a bad habit from a food safety perspective.
