Chocolate cake disaster hive mind help!

[Savethechocolatecake]

I have volunteered ( first mistake) to make chocolate cake for tomorrow. I usually make BBC good food ultimate chocolate cake X2 and then sandwich them together with ganache. Except I just put the first one in and I've forgotten to add sugar. So it's basically alot of chocolate, butter and a little flour. I will have to go back out to get more ingredients and the time has just gone up from now till 8pm to now till god knows when.
Any ideas on how to use this cake or rescue ideas?
I thought I could do Nadiyas cheesecake brownies and put little bits of the other cake in it too? (Which wouldn't require a shop trip or waiting for the first cake to finish before reusing the tin).
Help!

If you google moosewood 6 minute chocolate cake it’s super quick to make and bakes easily and is super moist and could still sandwich with ganache. Doesn’t need chocolate. Just cocoa

My suggestion is to pop to the shop and buy a chocolate cake. Up to you if you pass it off as your own, or if you just tell folks you had a kitchen disaster and this was your Plan B.

You offered to provide cake. Showing up with cake = mission accomplished.

I would 100% not use the sugar-free cake in any form.

Do exactly what @AphroditesSeashell says, for she is The Voice of Reason.

Aunt Bessie’s red velvet cake out a packet mix makes a nice chocolatey cake. You addd oil and eggs and it takes 2minutes to throw together

Make cake pops with the cake you have, the frosting you mix in will make it sweet enough.

I don't think the sugar-free cake will be very nice, even if you add it to something else.

I would buy a cake mix and cover with the homemade ganache. Cakes from mixes are usually quite nice really, with a decent ganache I think it'll be grand.
