Decorating ingredients

  • 2 x 400 g Renshaw Vanilla Frosting Pot
  • Rainbow Dust Twinkle Dust
  • Rainbow Dust Light Silver Metallic Paint
  • 2 x 50 g Rainbow Dust Pearlescent White Sprinkles
  • Rainbow Dust Ice Blue ProGel
  • Rainbow Dust Edible Glue
  • 1 kg Buttercream


Prepare your Equipment:

Step 1

You will need: 4 x 6” round x 1.25” deep vanilla cake layers, Cake board, Greaseproof paper, Baking tray, Turntable, Offset spatula, Palette knife, Dipping solution, Paint palette, Fine paintbrush, Flat paintbrush, Metal side scraper, Piping bags, No.12 round piping tip, 2D piping tip, Scissors, Flower & Modelling Paste snowflakes


Step 2

Stack, fill and crumb coat the cake layers using Renshaw Vanilla Frosting and chill for at least one hour.

Step 3

Place the cake onto a turntable and spread a small amount of Frosting all the way around the middle of the cake with an offset spatula to make a band for the fault line.

Step 4

Place the turntable over a sheet of greaseproof paper and a baking tray. Place a small amount of Pearlescent White Sprinkles into the palm of your hand and press onto the freshly applied frosting. Gather up the excess Sprinkles for reuse. Chill the cake until the Sprinkles have set.

Step 5

Colour the buttercream with a small amount of Ice Blue ProGel (up to 3g) to reach desired shade. 🌟 Top Tip: The colour of the buttercream will develop over time so go a shade lighter when colouring.

Step 6

Mix the Twinkle Dust with dipping solution to make a paint and paint over the Sprinkles using the flat paintbrush.

Step 7

Place a small amount of the Ice Blue buttercream into a piping bag fitted with a 2D tip and the rest into a piping bag fitted with a No.12 round piping tip. Using the round tip, pipe bands of buttercream above and below the Sprinkles and the top of the cake.

Step 8

Neaten the top of the cake with the spatula, then heat a side scraper in boiled water and dry off, scrape around the sides of the cake.

Step 9

Once the buttercream has set, paint the edges of the fault line with Metallic Light Silver Paint.

Step 10

Brush the snowflakes with edible glue and shake over either Sprinkles or Twinkle Dust to decorate. Push the snowflakes into the top of the cake and two on the front of the cake. Using the 2D piping bag, pipe mini drop flowers around the snowflakes and sprinkle over Twinkle Dust and Sprinkles to finish.
