Before you get started, take a look at our weighing and measuring skills guide. If you have digital scales, place one of the jars, bowls or containers on the scales and reset to zero. Weigh 40g oats into the jar, then repeat with the second jar.

Fill a tablespoon measure right to the top with yogurt, add it to one of the jars and repeat in the same jar (so you’ve added a total of 2 tbsp yogurt). Repeat with the second jar.

Fill a teaspoon measure right to the top with cocoa powder and use a cutlery knife to swipe across the top of the spoon, knocking any excess cocoa back into its container. Tip the cocoa into one of the jars, then repeat with the second jar.

Rinse the teaspoon measure under warm water to wash off the cocoa powder, then use it to measure a teaspoon of honey or maple syrup. Add this to one of the jars, then repeat with the second jar.

Slowly measure 175ml milk into a jug, then pour roughly half of the milk into one jar and the rest into the second – you can estimate this rather than weighing again.

Stir each of the jars well until the ingredients are combined and the mixture is chocolatey brown. Top each jar with a drizzle of honey and 4 raspberries, then chill overnight to enjoy for breakfast the next day.
