Do I put the glaze right away?

Or

Can I wait add the glaze and then the fondant with no buttercream?

or

Do i have to add buttercream too?

Please someone help me! Thanks

I don't usually fully glaze a rum cake that I plan to ice. It gets too moist that way.

If you are glazing then it works best to do it while the cake is still warm.

I would use a rum-based brushing syrup before icing, rather than the butter-based glaze rum cake often has on it.

Don't know about fondant, but I would be afraid that the fondant would get too moist if the cake was glazed with no buttercream layer underneath it, at least a thin one.

Thanks Sadie but I learned the hard way.

It was WAY too moist and even started to go through the buttercream because my fondant kept breaking off. I hd to put two thin layers of fondant and hopefully it will be good tomorrow morning.

Oh crud!
I am so sorry, I hope it holds up for you!
