Essential kit

You will need a microwave.


Put all the ingredients for the cake into a small mixing bowl and beat together until smooth.

In a small ramekin or bowl, mix together the ingredients for the cinnamon swirl until combined.

Pour half the cake batter into a large microwave-safe mug or split between 2 smaller mugs if making 2.

Dollop or pipe half the cinnamon swirl mix on top of the batter.

Pour the remaining batter on top and smooth it out, then pipe the remaining cinnamon swirl on top in a spiral pattern.

Mix together the sugar and cinnamon to make the cinnamon sugar, then sprinkle this on top.

Microwave on medium for 1 minute 20 seconds, or until there’s no wet batter remaining. Check your mug cake at the 1 minute mark to make sure it doesn’t overflow.

Leave to rest for 1 minute, as it will be very hot, then dig in and enjoy!
