Welcome to How To Cook That I am Ann Reardon
Today we are making a rainbow cake and we have got the new release of the Surprise Cakes
app ready so you can put a unicorn on top of your cake.
If you already have the app with the fireworks and the dragons then just hit update button
on your Surprise Cakes app to get the Unicorn as well, if you don't have it yet then I'll
add a link in the description below where you can purchase it on Android and IOS.
To make the rainbow cake you will need two packets of vanilla cake mix made according
to the directions on the pack.
I am using packet mix for this because it can handle the over-mixing when we are adding
our colors.
Split the mixture evenly between 6 bowls and then add a generous amount of red gel food
colour and mix it through really well.
Do the same with your orange, yellow, green, blue and purple.
Take your baking and tin cut out a circle of baking paper to line the base.
And then using the scraps of baking paper grease the base and sides of the tin and then
add the circle back in.
Pour one of your colours into the tin.
And then use a spoon to spread it out and push it out towards the outside and this is
going to help decrease that doming in the middle that cakes often have.
Bake that in the oven, the time that will take will depend on your packet mix so check
what it says and then take into account that you're only putting half a cake in.
Then repeat that with your other colours of cake batter.
For the icing in between the layers I am going to use a buttercream mixed with cooled ganache
and you can find those recipes on the website howtocookthat.net and I'll link to them in
the description just below this video.
Once your cakes are baked and cooled take them out of the tin and place a bowl or something
round over the top and trim off the outer edge.
This is just getting rid of that brown colour that's right on the edge colour because we
want our cake to be beautifully coloured and without any brown in it all.
Then level off the top using a cake leveler or you can use a knife.
Place your frosting into a piping bag or plastic bag, shake it down to the bottom and twist
it at the top to stop it coming back out the top end when you squeeze it.
Place a small amount onto your cake stand or plate and spread it out, this just stops
the cake from slipping off the cake platter.
Add your purple layer of cake and then pipe a thin layer of frosting over the top and
spread that out as level and flat as you can.
Then add the blue, green, yellow, orange and red layers.
Then use your piping bag to pipe more frosting onto the outside of each layer and then use
your spatula to smooth it out.
Piping it on first just helps to keep the different coloured crumbs separate to each
other so we don't get it mixed over the cake.
Then pipe the frosting on top as well in a circle and spread that out.
Go around your edge one more time to smooth that and then any bits of frosting that are
coming up above the top just push them flat going towards the centre of your cake.
Now we need to make a double batch of buttercream recipe which again is on the website, and
split that into 6 different bowls.
And just like we did for the cake batter use lots of gel colour, and I mean lots, to get
bright colors.
Now you can't use liquid colour here because you'll have to add too much and it will make
the buttercream split.
Take a spoon of your purple and add some cocoa powder to that and a little bit of black food
colouring to darken it.
Now take another little bowl and mix together some of your blue and some of your purple
to make a light bluey purpley colour.
Now you need to do this for each of your colours that are next to each other on the rainbow
to create a mid tone colour so that they are going to blend together nicely going up the
cake.
Then place each of those into ziplock bags.
And starting with the darkest colour, cut a tiny corner off and then begin to pipe dots
of the colour all the way around the base of the cake.
Then we don't want it to be in stripes, we actually want it to be sort of uneven, so
start to make little triangles coming up and then a dot above that.
You can do it in a neat pattern or you can do it uneven and random it really doesn't
matter.
Then take your purple and fill in the gaps and make the purple come unevenly high as
well just like we did with the darker colour.
Then continue that with your next colour as well.
This piping style with the dots of all different colours is inspired by a photo I saw of a
7-tiered cake by Michelle Brull which was the last cake she made before selling her
bakery so she doesn't do cakes anymore.
She used much larger dots than this and you can do that too but I like the look of the
little ones.
At the top pipe a circle of red dots then a row of each colour until you get to green.
And then in a bowl mix together some shredded coconut with some green liquid colour, just
keep mixing it until the coconut absorbs the colour.
If you've only got gel colour you can use that, just add a little bit of water to it
as well.
Then add a spoonful of your coconut over the top, all the way to cover the middle section,
up to that green line that we typed.
Then add your Unicorn marker on top, and you can colour it in lightly as long as the black
lines are still clearly visible so the app can lock onto it.
Turn your Surprise Cakes app, press the movie clapper and then line up the box with the
marker and a Unicorn will magically appear on top of your cake.
You can press the buttons down the bottom to make it move, you can change its colour
by pressing the buttons on the other side and you can even take photos with the birthday
kid behind it.
Afterwards they can keep the marker and play with the unicorn as well.
Then you can cut up your cake and serve it to reveal the colourful rainbow inside.
