I was tasked to make another galaxy themed cake, but had already made a galaxy mirror glaze cake! After a bit of thought, I decided to make some galaxy colored cake layers, cover the cake in a gothic black ganache. This cake design is inspired by Sweetapolita! I also added some of my favorite sprinkles from Neon Yolk Shop and Fancy Sprinkles. The recipes used can be found below:
My Favorite Vanilla Layer Cake Recipe
I made four, seven inch cake layers, which I colored two shades of blue, and two shades of purple.
I then covered the cake with room temperature dark chocolate ganache, which I colored black with gel food coloring. I’ve found that dark chocolate ganache is MUCH easier to color a true black than frosting. You can use the same techniques to smooth ganache that are used to smooth buttercream!
I added a sprinkles around the base, and piped on some ganache drops using a piping bag.
And that’s it! No fancy tips, no additional components, just a lot of ganache, and some colorful cake layers 🙂
What a great idea! Those sprinkles look so vibrant against the black ganache. Well done! I have watched some youtube clips of yours where you mention that you freeze your cakes after baking. Could you please share how you freeze them? I am wanting to make my daughters first birthday cake next month and will need to do the cakes a day or two in advance.
I put mine in a large tupperwear container! but you could also wrap them in saran wrap once they’re fully cooled!
This looks so similar to one of Sweetapolita’s cakes from her blog. But she starts with black cocoa powder so you don’t have to use a ton of black food coloring. Not sure if you are as well.

I actually didn’t use much to color the dark chocolate ganache! That’s the beauty of using ganache instead of frosting to cover the cake!
What colors did you use to color the cake? I love the vibrant shades ??
I used americolor gel in the electric blue, electic purple, royal purple, and classic blue shades!
The americolor gel colors that you use; is there any place where I can buy these as singles? This cake is gorgeous and would love to use the colors you have used in this.
of course! the shades should be up on amazon!
With the cake being iced in ganache, does it need to be kept in the fridge or is okay sit out on the counter? I just don’t want the ganache to harden too much before I serve it.
it will firm up either way! It can definitely sit out at room temp. I would recommend running your knife under hot water (and drying it) to cut into this cake, to help you get clean slices!
what kind of dark chocolate do you used?
I love your cakes!
I like using the whole foods brand!
