How long can you freeze a cake and it stay edible? I'm going to do a grooms cake that will be a 3D type cake with buttercream and MMF (rolled and modled). I would like to practice before making the actual cake (I'm still very new to this). What if my practice cake turns out great. Can I freeze it and thaw it out for the wedding?

I would imagine that it would still be edible come time for the wedding, as you can freeze the top tier of your wedding cake for your anniversary and eat it a year later! I wouldn't guarantee that the decorations would stay completely intact, or that you wouldn't have a problem with the icing sweating as it defrosts. I guess it depends on the intricacy of your design!

When's the wedding? I've told my brides how to freeze the top tier for their one-year anniversary, and it's always turned out great for them: freeze the cake solidly (deep freezer, preferably) with no cover. Pop the cake off the cardboard. Wrap well with plastic wrap then foil. Place back in freezer. One year later, remove cake from freezer and unwrap while still frozen....Obviously, you wouldn't want to use a freezer with weird freezer smells.

Hope that helps for you, mik_mcd!!

Thanks.
The wedding is in August. I was thinking I might make the practice version 3 or 4 weeks prior.

I've frozen cakes for up to 3 months with no problems at all ... I bake, wrap in saran, wrap in foil, place on cake boards and freeze. After frozen, I take the cakes off the cake boards and stack no more than 3 cakes on top of one another... when I get ready to defrost, I place them back on a cake board, take the aluminum foil off and leave the saran on the cakes until they come to room temperature. I then take the saran wrap off and decorate. Just make sure that you have nothing in your freezer that your cakes would take the flavor of; i.e., onions, sausage, etc.

Good luck! Let us know how it turns out for you

Wouldn't hurt to add a fresh box of baking soda (opened) to the freezer to absorb any odors that might be hiding in there.

I wouldn't freeze a fondant covered cake.

Ziploc 2 gallon freezer bags are great for freezing cake. After wrapping in foil place in the ziploc which will give you added protection against any smells.
