  4. Stir in the chocolate chips.

  5. Microwave mug cake for 60 seconds. Serve with a scoop of vanilla ice cream.

Recipe Notes

Top Tips and FAQ's 

  • Use a microwave safe mug. The cake will rise so it needs to be large enough to allow for that.
  • Instead of the choc chips, add 1 tsp of chocolate spread.
  • Don't be tempted to overmix the cake ingredients. You need to mix just enough to combine.
  • Don't be tempered to microwave for too long either! 45 seconds to 1 minute should be enough. My microwave is 800 W. You may need to adjust timings based on the wattage of your microwave.
  • Make sure that there is no metal on your mug.
  • If you don’t eat eggs you can substitute with the same quantity (around 20g) of mashed banana, plain yoghurt or buttermilk.
  • Egg Yolks just make for a fudgey cake and it helps to emulsify the fats and liquids.

Can it be made ahead?

This is best eaten straight out of the microwave.

You can make the batter before hand and keep it in the fridge for up to 48 hours.
