Does anyone think it's acceptable to freeze cakes. I've started doing craft fairs and weekend markets. I did my first one last Saturday. But it was so much work making and icing cupcakes as well as brownies and also a full time job. So I was thinking of taking the weight off by doing a bit during the week and freezing them until needed. I feel like I'm cheating the customer by doing this as they are not then fresh. 

The most successful bakers/cake artists on the planet freeze cake.  Go for it!

I bake and freeze iced cupcakes and iced brownies often.   I defrost them in their original packaging and they taste just as good as the day they were made.

 I also freeze cakes and cupcakes without icing.  Cakes that have been frozen for a few hours are actually easier to frost.

Just make sure the packaging is air-tight. Usually I would only freeze for up to two weeks although for my own use I have frozen for up to 2 weeks.  

The problem I've had before is as they start to defrost. They become sticky and the casing starts to peel off. 

Always freeze my Mud Cakes - it helps them *set* in my opinion.

I just take them out of the freezer the night before i require them - place them on counter - still wrapped as when i out them in freezer - and voila, in the morning they are ready and perfect for torting and ganaching :)

Sorry, my post should have been, "...but for my own use I freeze for up to 1 month".

It's not "cheating" anyone.  It's practical and proper freezing preserves freshness.

If you want to mitigate sweating, store the products in a cardboard box, not touching the box, and keep them boxed until they come to room temp.  The condensation will go to the box, not the product.

I always freeze my cakes before decorating them.  It makes them easier to work with and I honestly think a cake has a better texture and taste after it has been frozen.  Could all be in my head as I also think pizza tastes better when it is cut into triangles instead of squares.

Pizza is infinitely better when cut into triangles instead of squares :-D
