This does look better in a mason jar so i had a snoop and can get them at tesco 4 for £5, good deal
This recipe doesnt give amounts as it depends on volume of the mason jar and how many you make:
Recipe
Ingredients:
Nutella
Mini oreos
Milk
Vanilla icecream
Whipped cream
Peanut butter
Mini peanut buttercups
Method:
1.Crush the buttercups and oreos roughly. Spread nutella onto the rim of the mason jar and then cover in the crushed biscuit mixture.
2. In a blender blend icecream, milk, nutella and peanut butter until smooth. Personally i love a thick milkshake so i add more icecream than milk. Pour the milkshake half way into the jar and then drizzle some nutella onto the sides of the jar and then fill up to the brim.
3. Top with whipped cream and add crumbs of oreos and Buttercups.
