Chocolate & peanut butter mug cake


Ever have those nights when you desperately want something sweet for pudding, but the cupboards are bare and you don’t have the time (or energy) to bake something from scratch? Me too!

Well, did you know that with just a few ingredients you’re bound to already have in your pantry you can whip up a delicious mug cake – a flavoursome, warm cake for one that’s mixed, baked and eaten straight from a mug.

This recipe for chocolate and peanut butter mug cake is my absolute favourite – it’s warm, chocolatey and moist with a delicious, creamy peanut butter surprise tucked away in the middle. Not a fan of peanut butter? Don’t worry, just leave it out – the cake still tastes amazing.

The best part is that this cake takes less than five minutes to make from start to finish (including the bake time!) and barely creates any dishes, making it the perfect sweet treat for lazy winter nights at home.

Tip: Add a swirl of whipped cream and sprinkles for an extra special – and equally quick – treat kids will love!



  • 2 Tbsp flour
  • 1 tsp sugar
  • 2 tsp cocoa
  • ¼ tsp baking powder
  • 2 Tbsp chocolate chips
  • 2 Tbsp milk
  • 1 Tbsp oil
  • 1 tsp peanut butter, heaped


  1. Place all dry ingredients in a mug and stir until well combined
  2. Add milk and oil and mix until well combined, taking care to scrape the sides and bottom of the mug
  3. Drop peanut butter onto mixture and push in until completely covered
  4. Place in microwave and heat on high for one minute

        So I made 2 of these earlier this week. And then Mr Santé sneakily asked for another later in the week. I think that’s a win! Thanks so much Kirsten! Quick, easy and next to no dishes! And Mr Santé is quite right-these are delicious!

    We’ve just made these – our first foray into mug cakes – and they are MAGICAL. Scrape the pattern off the bottom of the cup amazing, and with lactose free milk – dairy free! Awesome!

      Thank you so much for the wonderful feedback Kate – so, so glad you like them! Clever using lactose free milk too x

    Love the idea – do this mug cakes have to be “baked separately” or is it possible to prepare two at a time? Thank you.

      Hi Beryl, I haven’t tried baking more than one at the same time but don’t think it would be a problem – you might just have to give them a little extra time in there. I’d suggest checking them with a tooth pick after the normal amount of time, then give them another 10-20 seconds until they’re baked through :) Let me know how you get on!
