First you're going to want to make the ears for the milkshake. I just took some melting chocolate and created triangles. I couldn't find purple melting chocolate, so I used white and added in some purple food coloring. All you need is a plate or something flat, and make triangles from the chocolate for her ears. Place them in the fridge until they harden.
Now you want to make the actual milkshake. Add in the vanilla ice cream, purple food color and milk until blended. You may need to add more of the ice cream or milk depending on how thick or smooth you want your shake to be.
Once you have it all blended, pour your milkshake into a cup. Now is when you want to add in all the toppings, and you want to be quick before the whipped cream melts.
Now you can add on the whipped cream to the top. Then take your Ferrero Rondnoir piece of chocolate and grate it over the whipped cream. Then sprinkle some of the purple sprinkles on top and put the chocolate cat ears on top as well. Make sure the ears are placed towards the middle or they may fall.
