Peanut Butter & Chocolate Mug Cake 

When you’ve got the sudden urge for cake there’s nothing better than a Mug Cake! I mean, they only take 60 seconds to cook! To me this is the Ultimate Mug cake recipe. Rich, chocolatey, with a gooey peanut butter centre. It’s super delicious!

This pudding isn’t overly big (think cup & saucer size, rather than an actual mug) so feel free to double the quantities if you need. I like the fact there’s no egg as it means there’s no risk of the pudding being rubbery. Also – it means halving or tripling the recipe is super easy.

Also, try my White Chocolate & Coconut version! 

peanut butter chocolate mug cake, recipe, one handed baker


  • 2 tbsp plain flour
  • 1 tbsp cocoa powder
  • 2 1/2 tsp sugar 
  • 1/4 tsp baking powder
  • A pinch salt 
  • 1 tbsp cooking oil (eg canola)
  • 1/4 tsp vanilla essence
  • 2 tbsp milk
  • 2 tsp milk chocolate drops
  • 1 tbsp peanut butter 
  • 1 tsp of water to sprinkle over the top


  1. In your mug/cup, stir together the dry ingredients (flour, cocoa powder, sugar, baking powder, salt). 
  2. Add in the vegetable oil, milk and vanilla essence, stirring until the mixture is smooth. 
  3. Mix through the chocolate drops.
  4. Spoon a dollop of peanut butter on top, and gently push down into the mixture.
  5. Sprinkle a teaspoon of water over the top (this stops the pudding from drying out) and microwave for approx 60 seconds on high (checking after 50 seconds).
  6. Enjoy!


  • Microwaves cook at different temperatures. This is based on a 900w microwave so alter the time if needed. The cake may need +/- 15 seconds. 
  • This makes a cup & saucer size pudding (which I find is big enough as it’s quite rich). If you want a bigger amount then double the recipe – no judgement here!
  • I like making these in pretty china cups BUT check if you do that’s there no gold in the pattern. Metal and microwaves don’t mix!
