I am still learning about decorating. I am going to try making a spongebob and friends cake for my grandson.
I use marshmallow fondant. How far in advance can I make the figures and have them still be fine to eat? Also, should I put them in a sealed container or leave out?
I need the cake for April 3rd and wanted to make these ahead.
I am sure the answer is on the site somewhere, but everything I search for does not take me to the right place.
Any help would be greatly appreciated.
I make them up to a month ahead & if you want them moist/soft keep them in an air tight container if not it doesnt matter, I think if you add tylose powder they will last longer too
HTH
Don,t add tylose if you want them to be edible. It will make them rock hard. That is the purpose of adding tylose to fondant, to make g/p. I don,t make mmf, but i read on this site, it gets hard anyway. If it is small figures, just make them up and keep in air tight container.Add some candy clay to the mmf , this will make them a little softer for eating. If they are small figure , i mean. hth
I never put them in the fridge always room temperature 
The problem with keeping figures soft enough to be edible is then they don't hold their shape very well. I make my figures well in advance. I just consider them "decoration" that won't get eaten. A lot of times, people will save them. I made a mario figure for my grandson's cake last July. We still have it and it looks just like it did the day of his birthday
