1. Pop some of your buttercream into two separate bowls and add a drop of the rose colouring to one bowl and three drops of rose to the other bowl and mix. Now you have your colours ready.

"My secret to the perfect buttercream is to whip it on a high speed for as long as possible – 5-10 minutes will make it the perfect texture to work with!"

2. Take some of the darker rose buttercream using your palette knife and spread the colour as you wish around your cake. Use your smoother to smooth out the buttercream. Pop back into the fridge for 10 minutes to firm.
