Learn how to make your own with our simple step-by-step recipe.

This cake will take about 3-4hrs to make and needs time to set so make sure you make it the day or well before you'd like to serve it so you have plenty of time for it to set.

You could use a theme of different colours - we've gone for rainbow but try different shades of blue or pink for a baby shower, green, red and white for Christmas or yellow and pink for Easter.

Step 1

Step 1

Prepare your cake board by sticking your chosen tape around the rim of the board. Leave to one side.

Make up the cake pop batter by mixing all the ingredients together in a large mixing bowl with an electric hand whisk until combined and divide into 6 bowls (98g in each bowl). Add the colour and mix until you have all 6 bright colours. Then add the coloured batter to your cake pop making machine and cook your cake pops accordingly. Victoria made 36 balls using the cake pop making machine method. If you don't have a cake pop making machine, try making mini cupcakes and trimming them with clean scissors to make a rounder shape.

Step 2

Step 2

Once your cake pops have been made and left to cool for a while, trim your cake pops with a pair of scissors to make them neat and round. Leave to one side.

Step 3

Step 3

Grease your 3 x 7inch cake tins and line with greaseproof paper. Make up your cake mixture by adding all the ingredients into a large mixing bowl and whisking with an electric hand whisk until combined. Add some of the mixture to line the base of the tin. Add the cake balls.

Step 4

Step 4

Cover the cake balls with the rest of the mixture, making sure you have an even amount of mixture in each cake tin. Don’t worry if the cake doesn't completely cover the tops of the cake balls, you won’t notice that when the cake has been put together.

Bake for 35 mins at 160°C/gas mark 3.


Step 5

Step 5

When the cakes are cool, wrap the cakes individually in cling film and pop them in the freezer for 1 hours.


Step 6

Step 6

Once your cake is ready to be decorated, make up your buttercream by beating all of the ingredients together with a wooden spoon or electric hand whisk.

Pop some of the buttercream onto the cake board to secure the cake in place. Place the cakes bottom side up as it's easier to add the jam and buttercream that way. Put the cake board onto a turn table, as this will make it easier to decorate your cake with buttercream. Add jam and buttercream to the first layer of your cake, pop the next cake on top and repeat until you have a secure stack of three. Victoria also added a tab so she could tell where the first cut on the cake should be to show off the best polka dot balls inside.

Step 7

Step 7

Add the first layer of buttercream to the outside of the cake with a large palette knife, removing the excess with the fondant smoother. Once the sides are covered, pop in the fridge for 30 minutes.

Remove the cake from the fridge and add another layer, making sure you leave the lip at the top of the cake. Chill for another 30 minutes.

Step 8

Step 8

Now fill in the top and chill for 30 mins. The chilled buttercream lip at the top of the cake will help you get the buttercream flat on the top. Don’t worry about any imperfections at this stage.

Once the cake has chilled, you can then smooth any imperfections. Using some boiling water, dip a small palette knife in to heat it up, wipe the knife on some kitchen towel and then smooth the knife over and lumps or bumps. You can press quite firmly to melt the lines away.


Step 9

Step 9

Mix the fondant and modelling paste together and divide into 5 and colour to your desired colours. Use various circle cutters to cut the circles out. If anything sticks, dust your counter and your cutters with a little cornflour. The longer you leave these to dry the better as then the circles are easier to pick up.

Step 10

Step 10

Using a water pen, glue the dot to the cake until you have completely covered the cake.
