Let's make a cake that's tie-dye inside and out
0:08
For tie-dye cake batter, divide your batter into four bowls, which you can weigh to make
0:13
sure they're all equal or just eyeball it, and add food colouring to each one
0:18
I'm making yellow, pink and blue and leaving one bowl plain. Spoon the batter into piping bags and pipe the colours into cake pans after you've greased
0:27
them, switching back and forth between the different colours and squiggling the batter
0:32
to make random patterns in the pans. Drag a toothpick through the batter to mix the colours up a bit and then bake as normal
0:40
I'm using baking strips around these pans, which help the cakes bake more evenly so that
0:45
they don't burn on the outside while still being raw in the middle and you'll find that
0:49
they rise higher and with flat tops instead of domes. Divide the cakes in half if you want more layers and then assemble your cake by alternating
0:58
cake and filling. This is my 4 Minute Buttercream and the recipe is on BritishGirlBakes.com
1:05
To frost the cake, start with a crumb coat, which is a very thin layer of frosting to
1:09
trap any crumbs that come off the cake so that they don't get into the final layer
1:13
of frosting. Chill the cake for about 30 minutes in the fridge to set the crumb coat and meanwhile
1:20
blend buttercream the same colours as the cake batter. Line the coloured buttercream up on a piece of cling film or saran wrap
1:29
You can put the colours into piping bags and pipe them on or just spoon them onto the plastic
1:34
and spread them into a line, like I'm doing here. Roll it up into a log and twist the ends and cut off one end and drop that end down into
1:43
a piping bag fitted with a star tip. This is a 1M
1:48
Now pipe onto the cake. I'm using this rosette technique but it doesn't matter what you pipe because you're going
1:54
to flatten it all in a minute, using a really fun technique that will expose a cross section
1:59
of whatever you pipe. Cover the whole cake, the sides and also the top if you want to, and then put the cake
2:05
into the freezer for 15-20 minutes. Then use a hot cake comb to scrape around the cake
2:12
You can heat the edge of the comb with a blowtorch or hold the cake comb under hot running water
2:16
from the tap or boil some water and pour it into a cake pan and dip the comb into that
2:23
You'll question yourself after the first few scrapes because it will look like you're destroying
2:27
your piping but keep scraping, reheating your cake comb after every few scrapes
2:33
If you piped onto the top of the cake you'll need to scrape that too
2:37
Now at this point the frosting is not going to be perfectly smooth because you'll have
2:41
gaps in between parts of the piping. What you're looking for is a smooth curve around the sides of the cake and a flat top
2:49
surface even though it will have lots of holes in it. Tie dye has those white markings or creases and to recreate those, spread white frosting
2:59
all over the cake. This is another part of this technique where it feels that you're ruining the cake but
3:05
the point of this white frosting is to fill in the gaps, not to cover up the other colours
3:11
So after spreading it all over, switch back to your cake comb and scrape around the cake
3:15
again to take off the excess white frosting and leave it only within the gaps in the piping
3:21
The white frosting will set really quickly because the coloured frosting is so cold so
3:25
using heat on your cake comb will make this much easier and quicker because it will melt
3:31
the outer layer of frosting instead of trying to scrape cold hard buttercream off the cake
3:37
So using the freezer to chill and then a hot cake comb to scrape, you've turned this
3:43
into this! There are so many possibilities for this technique and so many ways to add decorations to it
3:50
I'm adding some neon yellow borders using a 4B star tip and it would be really fun to
3:55
add some peace signs or smiley faces or other hippie style decorations but I'm too impatient
4:01
to cut into this to see whether the inside will match the outside
4:05
So I'm slicing straight into it and I'm not disappointed! Bright swirls of colour, my delicious very vanilla cake layers, my creamy 4 minute buttercream, perfection
