Sprinkle fault line cake
By Karen Keaney
You will need
For the buttercream:
500g unsalted butter at room temperature
1kg sifted icing sugar
Flavouring of your choice
A couple of tablespoons of liquid, either cooled boiled water or UHT milk
Colours of your choice
For the cake:
2x 6in round cakes
800g yellow buttercream
250g pink buttercream
250g blue buttercream
Brightly coloured sprinkles
25g each of yellow and blue sugarpaste
Gold lustre or highlighter
8in round cake board
Piping bags and nozzles (any nozzles will work; I have used the closed star style)
Make your buttercream
- Begin by using the whisk attachment on your stand mixer. Add the butter and beat on high until it becomes paler in colour.
- Turn the mixer to low and begin adding the icing sugar a cup at a time (if you have a cover/shield for the top of your mixer it’s a good idea to use it now).
- You can add a tablespoon of liquid once the mixture starts looking dry.
- Add a colour and flavouring.
- Once all the ingredients are added beat on high for about five minutes.
- Switch to the paddle beater and beat for another five minutes, this helps eliminate the air from the buttercream.
Fill and stack your cake
1. Split and fill your cakes straight onto the 8in cake board.
2. Once stacked, trim off any parts of the cake that protrude out - this gives you a nice base to begin applying the buttercream.
3. Using the palette knife, apply a thin coat of yellow buttercream all over the cake; this is called a crumb coat and seals in all the crumbs so that they don’t make their way into your final coat. Refrigerate the cake for about 15 minutes to allow the buttercream to firm up.
4. Apply a second coat of buttercream all over the cake.
5. Set the pro froster to the correct height for your cake.
6. Use the pro froster to smooth the top and sides at the same time. This will give you straight sides and top.
Apply the sprinkles
7. Place your cake on a wire rack over a baking tray. Apply the sprinkles to the middle part of your cake only, the tray underneath will catch the sprinkles that fall off.
8. Brush away as much of the spilled sprinkles from the bottom as possible. Refrigerate again until firm.
Prepare the fault line
9. Apply the remaining yellow icing with a piping bag above and below the sprinkles. You need to be generous with the icing so you don’t scrape off the sprinkles in the next step.
10. Smooth out the buttercream using a side scraper. Take care not to get too close to the sprinkles.
Decorate the top
11. Apply a layer of buttercream to the top of the cake and level using the palette knife.
12. Insert the nozzles into the piping bag and fill the piping bag with blue icing. Pipe swirls of icing on the top of the cake as shown.
13. Repeat for the pink icing, but pipe smaller swirls in between the blue.
14. Pipe one large blue swirl in the middle.
15. Fill in the top with little pink swirls.
16. Add some sprinkles all over the top.
17. Clean up the board with a paper towel.
Make the fault line
18. Mix some gold lustre or highlighter with some confectioner’s glaze and paint it along the top and bottom edge of the fault line.
19. Make some yellow and blue balls by rolling small pieces of the coloured sugarpaste in your hands.
20. Sprinkle the balls on the cake, you can also add some into the fault line.
21. Finish the board off with a ribbon and bow (you know the rules when it comes to using ribbon on cake).
22. Pipe some piping gel or a very thin layer buttercream on the board and spread some sprinkles onto it.
