To make pink ganache add cream and chocolate to a microwave safe bowl and microwave for 20 seconds at a time until smooth. Take care not to burn it as it's only a small amount. Add pink food dye and mix in until the ganache is evenly coloured with no white streaks. Add to a squeeze bottle or zip lock bag and set aside.
Add milk, ice cream, blue food dye and bubblegum essence to a blender and blend on high until everything is well combined.
Squeeze some drips of pink ganache around the inside of your serving glass. Add the bubblegum milk and finish off with a generous helping of fairy floss.
Tip: If you want to make your milkshake extra chill on a hot day add a couple ice cubes in with your milk ingredients.
