This 3 ingredient mug cake is ideal for those nights when you want a sweet treat but didn’t buy the good snacks at shopping! It’s quite possibly not the best recipe you’ll find on this website, as it is just so basic, but it will satisfy your sweet tooth for sure.

My 3 ingredient mug cake recipe takes just 30 seconds to prepare and 60 seconds to cook! It’s a doddle to make, just make sure you use a microwave safe mug. A cake in under 2 minutes – what more can you ask for?

If you’re looking to bake a cake, and put a little more effort in, this Vanilla velvet cake looks lovely! As does this honey cake.

Ingredients for 3 ingredient mug cake:

1 egg (large ideally)

80g chocolate spread (any is fine)

30g plain flour

Cooked chocolate chip muffins in a baking tray with text overlay that says ultimate chocolate chip muffins

Method for this chocolate mug cake:

Choose a microwave safe mug. I tend to go for a larger one (The one I use holds 315ml of liquid).

Add the chocolate spread to the mug.

It’s just over 5 tablespoons if you don’t have weighing scales to hand.

Crack in the egg. Mix well.

Add the flour.

Homemade oat biscuits on a cooling rack

Mix really well until everything is combined.

Microwave for 50-60 seconds. I always check at 50 seconds and do another 10 seconds if needed.

Serve with ice cream, a dusting of icing sugar or just eat it alone with a spoon! I eat it from the mug, without generating more washing up!

  • 80 g chocolate spread I use a cheap version of Nutella
  • 1 egg large
  • 30 g plain flour


  1. Get a mug. Make sure it is microwave safe!

  2. Place the chocolate spread into the mug. If you’re lazy and don’t want to weigh 80g then go for 5 tablespoons and a little dash more.
  3. Crack the egg in. Mix it well.
  4. Add the flour. Mix this round until everything has been mixed together well. This only takes a few seconds of effort and makes sure that your 3 ingredient mug cake cooks correctly.
  5. Place in the microwave for 50-60 seconds. My microwave is 750w and I find that 60 seconds is perfect when using a slightly smaller mug. With this mug I needed 70 seconds. However, err on the side of caution. Watch the microwave and do not let the cake overflow. If the cake goes to overflow then turn the microwave off immediately.
  6. That’s it! Serve it alone, with ice cream, dust it with icing sugar, whatever. It’s a tasty way to have a nice treat after dinner, without breaking the bank. It IS high in calories, because of the chocolate spread and flour, but it tastes delicious so enjoy!
