How to keep sponge fresh

post #1 of 17
Thread Starter 
Hi, I am relatively new to cake decorating but have been teaching myself over the past 4 months.

I have 3 cakes due this weekend, 2 on saturday morning and 1 on sunday. I work Ft and have a 2 year old and think Ive taken on a bit much lol

I am wondering how long sponge cake stays fresh for or how I can prolong the freshness?? I was thinking of trying to complete one of the cakes by Thursday night but will need to make it after work wednesday and thursday nights and its required for saturday.

The cake will be sponge, dirty iced with buttercream and covered in fondant. I am looking at covering it in fondant on wednesday or thursday night.

Any ideas on time frames too keep it fresh??

Thanks!

Good question? I'm new at this too but I think I have read that the crumb coat will help keep it moist. Are you planning to put it in the fridge? That may help as well but am not positive! Good luck!

Crumb coating and applying a 2nd coat of thicker / full coverage icing will keep it moist and fresh. I baked a cake on a Monday and delivered it on a Saturday and heard from all the party guests that was the best sponge cake they ever had! I've been getting business from them every since!

I know some cake decorators throw in a box mix into their recipe to keep it fresh...from the preservatives. If you are using box mix base then you can do it a week in advance and ensure it is WELL COATED in buttercream so no air gets in. Just what has worked for me.

I don't freeze or refrigerate my cakes ever.

Excellent! I was hoping to be able to make them all early in the week and to do it each night after work.

You said that you don't ever refrigerate your cakes but doesn't the buttercream separate or go off as such if its not refrigerated? I would have thought to crumb and then finish coat it in buttercream and then refrigerate? Do I put it in a container to sit for that time?

Sorry for the questions I just want to make sure I get it right!

Thanks!

I use the wilton BC recipe which crusts on my cakes. I put on a thin layer then a thicker 2nd coat. It's crusts in one day and I don't have to refrigerate. It has never slid off and i live in the Caribbean with temperates of 34 degrees everyday!

I just cover it with a cover or something to keep it safe. The icing seals in moisture and prevents air from drying out the cake.

Please post and let us know your end results!

The Wilton BC has shortening in it but I use a butter based buttercream, do you think this will make a difference?

Hi,yes butter-based BC will be a big hot mess. My 1st BC was with all butter and it was a disaster for me. It never set. Was wet and like butter at room temperature and I am in 34 degrees weather daily. The shortening helps BC to crust. I think you will find better results with a shortening based BC. You get 3 or 4 cups of BC from the Wilton recipe. You will only know how much you need to cover your cake size by experimentation over time. Buy enough BC ingredients for 2 recipes just in case you need more. I always make 1 batch 1st and then make a 2nd depending on how much I need again. Let us know how this comes out for you.

i am in the topical humid singapore.
when i crust my cake and then go through a next layer, i put it in the fridge to get it all set.
But once i take it out, it get wet from condensation... leaving it out... the buttercream will melt.. so I am in total confusion.

and when I remove from the fridge to cover with the fondant,the buttercream gets messy...

I've got about a month more to practice before my two tier cake get out into the public.

I have experimented like four times and each time I get a different or a new problem to solve...

What should I do?

You need to use a crusting BC - wilton or Indydebi's recipe which you can find here on most saved recipes. Don't refrigerate your cake covered in BC. IT WILL CONDENSE! You will get a lot of water droplets all over and it will mess up your fondant. Leave it to crust at room temperature for one day. Then apply your fondant or if not, put on a thicker 2nd coat of BC. Trust me,it will work.

Thanks for the reply icon_smile.gif

I used this particular recipe for my buttercream:
1/2 cup shortening
1/2 cup butter, softened
1 teaspoon vanilla extract
4 cups confectioners' sugar
2 tablespoons milk


will it still work?

I was thinking of increasing my shortening amt in comparison to the butter so that the buttercream will be able to hold in the heat and humidity...

I have looked through the recipes listed on the forum... the really good ones requires some ingredients that seems impossible to find in the stores... Now, my head is bursting trying to solve individual problem with making the fondant cake.


Thanks in advance...

I use this same recipe but substitute margarine for butter. Butter at room temperature is a mess and slides. You need a sturdy and firm base to apply fondant. Try using margarine in a block not the soft spread margarine. You should get good results.

Your recipe is good as in with the 2tbsp milk, 4 cups PS etc

For condensation problems I wrap my cake in Saran wrap, then foil then refrigerate (or sometimes slightly freeze if I'm carving). Once I pull my cake out the next day I let it rest, still fully wrapped so the condensation forms on my foil instead of the cake. Then I cut/pull everything off once my cake is at room temp voila no soggy cake!
