Hi! I'm Emily of British Girl Bakes and I'm going to show you how to make a
0:04
black cake with black filling and black frosting. For a black cake I recommend
0:09
making a chocolate cake since it's already dark brown and you won't need cups and cups of black food colouring. This is my perfect chocolate cake batter
0:18
which has cocoa powder in it which you dissolve in water. I'm using this black
0:22
cocoa powder which is naturally black or if you want to use normal cocoa powder
0:26
you can add black gel food colour until you get the shade of black you want
0:30
Definitely use a gel colour instead of liquid because they're much more
0:34
concentrated so won't affect the consistency of your cake batter. By the time I've added all of the black cocoa powder mixture the cake batter is
0:44
really dark and it's going to get darker as it bakes but as an experiment I'm
0:48
filling half of my cake pans with the batter as it is and then adding a
0:52
maracola super black gel colour to the rest of the batter to see if it makes
0:56
the cakes any darker. These are mini springform pans and I love using them for
1:01
4 inch cakes because they're so easy to get the cakes out after baking and I've
1:05
put the link for these ones in the description below the video. The batter
1:09
with black gel colour looks slightly darker at the moment but let's see how
1:13
they look after baking. Exactly the same! I can't tell the difference between the
1:18
cakes with and without the black colour added. I've leveled this cake layer and
1:22
you can see that the inside is jet black as well. For black filling and
1:27
frosting you have two options, chocolate ganache or buttercream. For ganache, melt
1:32
two parts of chocolate and one part of heavy whipping cream or double cream so
1:37
this is two cups of semi-sweet chocolate and one cup of cream. I've put the link
1:41
for the recipes in this tutorial with measurements in grams and ounces and
1:44
cups in the video description. This ganache is already a nice dark brown so
1:50
you don't need to add much colouring to make it black. I'm adding about a teaspoon of Americolor super black gel colour. Let the ganache come to room
1:57
temperature which will take one or two hours or you can speed up the process by
2:01
putting it in the fridge and stirring it regularly to keep it smooth. Then you can
2:07
fill and frost your cake with it. If you prefer buttercream you can use black
2:11
cocoa powder to make it black. I'm using my 4-minute buttercream but I haven't
2:16
added the milk or cream at the end of the recipe. Instead I'm mixing a third of
2:20
a cup of black cocoa powder with a quarter of a cup of hot water to make a
2:24
paste and then adding it to the buttercream and you can see it's already quite dark from the cocoa powder but definitely not black. Now I'm adding
2:33
3 quarters of a cup of melted semi-sweet chocolate which makes it a bit darker
2:37
and then a teaspoon of black gel colour and then I'm covering the bowl and
2:43
letting it sit for an hour to darken. The buttercream does darken a bit on its
2:48
own with time but I want a really black frosting so I'm adding another teaspoon
2:52
of black gel colour and I'm really happy with this shade of black which is going
2:56
to get even darker with exposure to air. And there's the final colour after
3:02
another hour! So here's my black cocoa cake with black cocoa buttercream
3:07
filling and frosting and now it's time to cut into it! Wow it's so black! Now let's see if it stains my teeth
3:27
All clear! The black cocoa powder does most of the work for you and you really
3:32
need very little gel colour to make the cake or buttercream really black. A black
3:36
cake is fun for Halloween but also makes a very dramatic looking cake, both inside
3:40
and out! Thanks for watching! I share a new cake decorating tutorial every week
