I made this cake for Linda’s birthday.  Her husband secretly ordered it from me and I thought that such a romantic gesture wouldn’t be complete without some love hearts!

It really is as simple to make as the photos look – you dye the cake batter, pour into the pans and bake!

It is based on a white mud cake, filled with white chocolate ganache and covered in sugar paste
This cake was so much fun to make and eat!  I love the surprised look on peoples faces when you pull out the first slice ~ Rainbow cake is something that makes everyone smile 🙂

Two things make this cake special

1. The Rainbow Inside. A really big surprise if the recipient and/or guests have no idea what is inside.

2. The cake is based on a White Chocolate Mud Cake. Lots of people are scarred to use colours with Chocolate mud cakes if they do not have the special chocolate colours. I did a lot of research before I used my ordinary food colours and the reason they work is because we are not colouring 100% pure chocolate. The other ingredients magically make it alright to use Wilton or AmeriColor (these are the only two makes that I have tried so far).

7″ White Chocolate Mud Cake (Planet Cake recipe)

I used 2 x 7″ pans
180g butter
180g white chocolate
160ml water
195g SR flour
180g plain flour
240g caster sugar
2 eggs, lightly beaten
1 tsp vanilla essence


Ganache

780g white chocolate, finely chopped
270g pure cream
Sugarpaste

730g yellow sugar paste

small amounts of orange, red, purple, blue and green sugar paste
White Chocolate Mud Cake Method

    1. Preheat the oven to 180C.
    2. Grease and line bases of both cake pans with baking paper.
    3. Combine chopped butter and water in a saucepan.
    4. Stir over low heat until butter is melted. Turn off heat, then add the chocolate and stir until it has melted and is well combined.
    5. Sift flours into a bowl. Add sugar, a pinch of salt and make a well in the centre.
    6. Pour chocolate mixture, egg and vanilla into the well then stir with a wooden spoon until well combined.
    7. Divide the batter equally amongst the 6 bowls. Weigh your mixing bowl before you begin adding ingredients and then subtract the weight of the bowl from the final measurement after the batter is completed. Divide that number by six and add that weight of batter to each bowl, and then whisk a fair amount of the appropriate food colour into each bowl. Keep in mind that the color of the unbaked batter will be the color of the baked batter.
    8. I poured 5/6th of the red batter into the pan that would be the top tier. I spread it out a little to touch the sides of the pan and be a little thinner in the middle.
    9. I then poured 4/6th of the orange batter in the middle of the pan on top of the red. I moved it about a little to make a good circle.
    10. I then poured 3/6th (i.e. 1/2) of the yellow batter on top followed by the green, blue then purple.
    11. In the second pan that would be the bottom tier, I first of all poured 5/6th of the purple batter followed by the blue, green, yellow, orange and finally red.
    12. Bake for 30 -35 minutes or until a skewer comes out clean when poked into the middle of the cakes.
    13. Leave in tins to cool completely on a wire rack.
    14. When cool, cut the domes off both cake and sandwich together with white ganache making sure that the bottom tier is placed upside down to create the design in my picture at the top of this post.

White Ganache

1. Place chocolate pieces in a large bowl.
2. Put the cream in a saucepan and bring to boiling point. Pour the cream over the chopped chocolate and mix with a hand whisk until the ganache is smooth.
3. Allow to cool completely and then leave to set overnight, if possible.

Easter Cookie Tutorial

These cookies are iced using the ‘Outlining and Flooding’ technique which is simple to learn. The outline works as a dam or wall to hold the runny icing which you use to fill in the main parts of the cookie.
I made these cookies in 3 delightful flavours: chocolate, vanilla and gingerbread.
 

Chocolate Cookie Recipe

makes about 24 medium-sized cookies
275g plain flour
100g self raising flour
75g cocoa powder
125g granulated sugar
125g salted butter, diced
125g golden syrup
1 large egg, beaten
Sift flours and cocoa, add sugar and mix well.
Add butter and using finger tips rub till mix resembles breadcrumbs.
Make a well and add syrup and egg.
Stop as soon as a ball has formed.
Cover and chill till ready to use or roll and use immediately.

170C for 14-18 mins

Vanilla Cookie Recipe

makes about 24 medium-sized cookies

200g unsalted soft butter

200g caster sugar
seeds from one vanilla pod or 2 tsp of best vanilla essence
1 egg, lightly beaten
400g plain flour
In the mixer with paddle attachment, cream the butter, sugar and vanilla till well mixed and just creamy in texture. Do not overwork or cookies will spread during baking.

Beat in the egg till well combined.

Add the  flour and mix on low speed until a dough forms.
Cover with cling and place in fridge for at least 1 hour.
Place dough on floured surface and knead briefly.
Roll out to 5mm thick.
Cut out your shapes, then, using a palette knife, lay them on a baking tray lined with greaseproof paper.
Chill again for about 30 mins.
Preheat oven to 180C/170C fan and bake for about 10 mins, depending on size, until golden brown at the edges.
Transfer cookies to a wire rack and allow to cool before decorating.

Gingerbread Cookie Recipe

makes about 24 medium-sized cookies
90g butter
150g soft brown sugar
90g golden/corn syrup
425g Plain flour
1 tsp baking powder
2tsp ground ginger
1tsp mixed spice
1 medium egg (beaten)
Gently heat butter, sugar and syrup until dissolved.
Cool slightly for five mins.
Pre-heat oven 180C and lightly grease baking trays.
Sift flour, baking powder and spices tog into mixing bowl and make a well in centre.
Add melted mixture and egg into the centre. Bind tog with knife then use hands to form soft dough.
Sprinkle work surface with flour and roll out the gingerbread to 3mm (1/8″)

Bake in centre of oven for 13 mins.

Transfer cooked gingerbread to a cooling rack.
I have been using a homemade Cookie Leveller to roll out my cookie dough. I have all the instructions if you would like to make one.

Royal Icing Recipe click here

A thicker consistancy icing is used to outline the cookie shape and then a thinner one (like custard) to fill in.

Outlining

Outline your cookies first and leave at least 15 minutes before you flood the inside of the ‘dam’ (outline). If the outline is a dark colour, it is best to wait 24 hours so that the colours don’t bleed into each other.
Outlining the egg
To outline the cookie hold the bag at 45 degrees and position the tip on your cookie. Put enough pressure on the bag so that the icing comes out and you can start moving in the direction that you want your icing to go. Start lifting the pipping bag till it is a few centimetres above your cookie and the icing just falls in a continuous line onto the cookie below. Come back closer to the cookie at corners and when finishing also reduce or stop pressure on the bag to go more slowly or to stop.

Flooding

Use a number 3,4 or 5 sized piping tip depending on the size of your cookie. Fill in one area at a time quickly zig zagging back and forth. Don’t worry if you haven’t filled in every spot: speed is more important at this point. To fill in these little missed bits just use your piping tip, toothpick or small paintbrush (used only for food), to push the icing into your missed bits.

Decorating

Bunnies with White Tummies
Outline and flood your bunny with your chosen colour and immediately add a circle of white icing for the tummy. The icing will quickly sink down till a smooth or slightly domed tummy area remains.
Once completely dry add cheeks and front paws.
Add nose and eyes once cheeks are dry or almost dry.

Bunnies with Spots 

Outline and flood your bunny with your chosen colour and immediately add little blobs of white icing to make the dots.
Once completely dry add the bow using a No.00 piping nozzle.  
Pretty Little Easter Eggs
Outline and flood your eggs with your chosen colour and immediately add little blobs of white icing to make the dots.
Once completely dry add the bow using a No.00 piping nozzle.
Yellow Chicks
Outline and flood your chicks with yellow and when completely dry add little feather details, a pink beak and an eye.
Bunny Faces
Outline and flood each face with your chosen colour leaving the centre of the ears icing free.
Once dry add the cheeks in the same colour.
Once completely dry use a contrasting colour to make the nose, whiskers and middle ear. While still wet sprinkle the ears with coloured sugar sand or similar. If you are worried about the sprinkles sticking to the nose and whiskers you can add the nose and whiskers after the sprinkles have been added.

Storing

Let the cookies dry for 24 hours before you package them.
Store in an airtight container in a cool dry place out of the sun (sunlight can fade the colours). The cookies can keep for up to 2 months but I prefer to use them up within a month.

Traditionally a thicker consistancy icing is used to outline the cookie shape and then a thinner one to fill in. I have come to prefer using the same icing to outline and flood my cookies because it saves time preparing and filling icing bags twice for each colour.
Outlining
Outline your cookies first and leave at least 15 minutes before you flood the inside of the ‘dam’ (outline). If the outline is a dark colour as here, it is best to wait 24 hours so that the colours don’t bleed into each other.

To fill in these little missed bits just use your piping tip, toothpick or small paintbrush (used only for food), to push the icing into your missed bits.

Decorating
To colour the wings by ‘melding’ several colours into each other then you must do it straight away. The base layer starts to dry quickly so you need to add your next colours as fast as possible.

Sweetopia

Add two black lines of icing with a contracting colour in-between then drag through the lines with a cocktail stick or a pin. Have a look at some pictures of real butterflies to get an idea of what it is that you want to achieve.

The ‘eye’ of the butterfly is then made by layering a few coloured dots on top of each other, with the black as the final coloured dot.

Storing
Let the cookies dry for 24 hours before you package them.
Store in an airtight container in a cool dry place out of the sun (sunlight can fade the colours). The cookies can keep for up to 3 months but I prefer to use them up within a month.

I would like to thank Sweetopia for the original idea and for 3 images.
