Use plain milk when the recipe specifies it and you want to measure flavouring and sugar separately. Choose a ready-to-drink chocolate milkshake when the recipe calls for a flavoured drink or you are deliberately adapting it. For a larger batch, Tesco Groceries lists Yazoo in a 1L bottle; Müller UK & Ireland lists Frijj at 330ml, and ASDA Groceries lists Mars at 400ml. Check the required volume, ingredients and allergens before making a substitution.
If a cake, traybake or dessert needs a substantial amount of chocolate-flavoured liquid, compare the recipe quantity with the bottle size. Tesco Groceries lists a 1L Yazoo bottle with five 200ml servings; Müller UK & Ireland lists Frijj at 330ml, and ASDA Groceries lists Mars at 400ml.
A ready-to-drink milkshake brings its own flavour and other ingredients to a recipe. If the recipe specifies plain milk and separately measured sugar or cocoa, check the drink’s label before deciding whether to adapt it.
Check the exact bottle’s allergen statement before preparing food for guests. The listed Yazoo, Müller Frijj and Mars drinks contain milk; the ASDA Groceries listing for Mars also declares barley.
Start with the liquid specified by the recipe, then work out the volume you need and check the label of any flavoured drink you might use.
| Priority | What to check | Your needs |
|---|---|---|
| Recipe liquid | Does the recipe call for plain milk or a flavoured drink? Check whether sugar and cocoa are measured separately. | If I need to follow a plain-milk recipe closely, I would measure any added flavouring separately rather than assume a milkshake is interchangeable. |
| Pack volume | Compare the required volume with the bottle size and the number of bottles in a pack. Tesco Groceries lists Yazoo at 1L, Müller UK & Ireland lists Frijj at 330ml, and ASDA Groceries lists Mars at 400ml. | For a large batch, I want enough liquid without opening more bottles than the recipe requires. |
| Ingredients | Read the ingredient list and nutrition information for the exact drink. ASDA Groceries labels the Mars drink as no added sugar and also states that it contains sweeteners. | I want to know what the drink will add to the recipe beyond the ingredients I have measured myself. |
| Allergens | Check the allergen statement on the pack. The listed drinks contain milk, and ASDA Groceries also declares barley for Mars. | When baking for guests, I need to check the bottle I will actually use, not rely on the flavour or front-of-pack wording. |
| Opened bottles | Check the pack’s refrigeration and use-after-opening instructions, then consider how much the recipe will leave. | If I only need part of a bottle, I want a plan for using the remainder within its labelled storage instructions. |
A flavoured drink can introduce sweetness and flavour that the original recipe does not account for.
Check whether the recipe calls for flavoured milk. If it specifies plain milk and separately measured ingredients, use those quantities as your starting point rather than assuming a direct substitution.
A 330ml or 400ml bottle may leave a large recipe short of liquid, while opening several bottles can leave some unused.
Write down the recipe’s required volume and compare it with each bottle or multipack before shopping.
ASDA Groceries labels its Mars drink as no added sugar, but it contains sweeteners and declares milk and barley. That claim does not answer whether the ingredients suit a recipe or its guests.
Read the ingredient list and allergen statement on the exact pack before baking.

The eight separate 500ml bottles provide 4L in total, but a recipe may need only part of one bottle. Check the exact pack’s ingredients, allergens and opened-bottle instructions; do not assume this shake will behave like plain milk in baking.
It depends on the recipe’s liquid quantity. Tesco Groceries lists the 1L Yazoo Chocolate Milkshake as five 200ml servings; compare the amount your recipe requires with the bottle before buying.
Do not assume a direct substitution will give the same result. A ready-to-drink chocolate milkshake has its own ingredients and flavour, so use it when the recipe calls for a flavoured drink or when you intend to adapt the recipe.
No. ASDA Groceries labels the 400ml Mars drink as no added sugar, while its product information says it contains naturally occurring sugars and sweeteners. Check the exact pack’s nutrition information and ingredients for your recipe.
Yes. The listed Yazoo, Müller Frijj and Mars drinks contain milk, and ASDA Groceries also declares barley for Mars. Check the allergen statement on the exact bottle before baking for guests.
Follow the opened-pack storage instructions on the bottle you bought. Before opening several bottles, compare the recipe quantity with each bottle’s volume so you know how much will remain.
