In this video I'm going to show you how to make jet black frosting, how to add colourful galactic
0:05
details and sparkling constellations, and how to make this gravity-defying cake topper. I'm using
0:11
my 4 Minute Buttercream for this cake and the recipe link is in the video description. Add
0:16
black gel colour and you'll need a lot of this, especially if you're starting with plain vanilla
0:20
buttercream. You'll need a lot less colour if you start with chocolate and cocoa powder and I've
0:25
put my link for my black buttercream that won't stain your teeth, which uses those ingredients
0:30
in the video description as well. The colour will develop as it sits so after mixing it in
0:36
cover the bowl with a lid or with cling film or saran wrap and after an hour it will be several
0:40
shades darker. You can add even more colour if you want and then cover it again and wait another
0:45
hour. Frost your cake as normal with the black buttercream and scrape around the cake a few times
0:50
with a frosting smoother until it's fairly smooth but don't worry about getting it perfect yet
0:56
Now spread on a few dabs of brightly coloured buttercream like pink and teal and purple and blue
1:03
Scrape around the cake once to blend the colours and then touch up any indents in the frosting
1:07
by spreading on more frosting, either the bright colours or black, depending on how subtle you want
1:13
the bright colours to be. I made these bright colours using gel colours as well. Scrape around
1:18
the cake again and the purpose of this is to blend the bright colours into the black
1:23
and also to finish smoothing the frosting. After each scrape, touch up any indents, either with
1:28
black to dull the colours or add more of the bright colours if you want them to be more intense
1:34
When you're happy with the sides of the cake, tidy up the top edge by scraping any overhanging
1:38
frosting into the middle of the cake and then swipe it off the cake on your offset spatula

to my channel for a new cake decorating tutorial every week! As the frosting starts to set, which
1:54
will happen within about 10 minutes if your cake layers are chilled, any coloured frosting you add
1:58
won't blend as well with the black frosting so the patches of colour will be more obvious
2:04
Now it's time to add some constellations! I'm using silver luster dust for this, mixing it with
2:09
a few drops of vodka or any other clear alcohol will work too or a clear extract like lemon
2:14
extract or artificial vanilla extract. Mix it to make a thick paint and then flick your paintbrush
2:20
towards the cake, stopping it just before the cake to let the silver paint spray out over the cake
2:25
I like to tap the paintbrush against a finger to stop it suddenly and create the spray
2:30
If you don't use that extra finger, the motion you're using is a quick flick, how you would cast
2:34
a spell with a magic wand. You can use white icing colour for this instead of silver paint
2:40
Remember to do this on the top of the cake as well. Wipe any smudges of frosting or silver
2:45
paint off the cake board using a paper towel wrapped around your finger. I show how to make
2:50
this gorgeous black heart topper out of chocolate in my tutorial on geometric hearts and I've put
2:55
the link in the top of the screen and in the video description. When it sets, poke a toothpick
3:00
or wooden skewer into the bottom of the heart for support and before adding it to the cake
3:05
pull apart some candy floss or cotton candy to make it nice and fluffy and cloud-like and then
3:10
place that on top of the cake. Push the heart on its stick into the middle of the cotton candy to
3:15
skewer that in place and to conceal the stick so it looks like the cotton candy and the heart are
3:20
floating above the galaxy cake. Rearrange it by pinching it and pulling it apart to make it
3:26
fluffier and there it is! A stunning galaxy cake with a gravity-defying cake topper. For cake
