Some people may know this, it's a very simple recipe...
-Sweet/choc/biscuit that you want the shake to be
-Soft-scoop Vanilla Ice-cream
-Blender (the thinner+powerful the better)
Take your sweet/chocolate, put it in the blender, and blend with pauses for around 30-40 seconds, until the ingredient is disintigrated to your liking, then remove it and pour it into a glass for now, then add three scoops to the blender, pour in the blended shake flavour, then pour around 100ml of milk in, close the lid, and blend until the shake seems mixed properly, and if you want it thicker, add more ice-cream, and blend for around 10 seconds...and you have a delicious shake of the flavour of your shake. I have made Lion, Millions, Kinder Beuno, Oreo, Hobnobs, Dairy Milk + (wanted to try this LOL)Salt and Vineger Walkers flavour shakes, and MOST of them were f'in delicious! If you like Shakeaway/Miishakes etc, make them at home and save a fortune...i'm on 1 a day atm LOL
