    What makes this chocolate mug cake the BEST EVER?

    I’ve tried so many mug cake recipes, and after some experimenting, I finally came up with the ultimate mug cake! But what makes my version so great?! Apart from testing out different ratios of ingredients, it’s the chocolate, instant coffee and vegetable oil that sets this mug cake apart.

    Coarsely chopped pieces of chocolate run through the mug cake, and when melted in the microwave, add the most incredible mouth feel! Instant coffee is another game changer, and is commonly added to chocolate based treats to enhance the chocolate flavour. Lastly, vegetable oil just makes for a far moister cake!

    Can I double the recipe?

    Yes you totally can, but you will need to use a bigger bowl/cup and microwave the cake for longer. I’d start with 1 minute 30 seconds, and then check your cake.

    IMPORTANT: For accuracy, I would recommend using the gram measurements provided as those are the exact quantities I use. Cup measurements are given as estimates (based on US cup measurements) to make it easier for those who do not have a scale.

    Ingredients
     

    • 3 tbsp flour - regular all purpose
    • 2 tbsp white sugar - brown okay too - see note 1
    • 4 tsp cocoa powder
    • ¼ tsp baking powder
    • 1 pinch salt
    • 3 tbsp milk - full fat preferred
    • ¼ tsp instant coffee
    • ½ tsp vanilla essence/extract
    • 2 tbsp vegetable oil - I use canola, but any unflavoured oil will work
    • tbsp 50% dark chocolate - coarsely chopped

    Instructions

    • In a microwave safe mug, combine the flour, sugar, cocoa powder, baking powder and salt and mix together with a fork.
    • In a separate bowl/mug, mix the instant coffee into the milk, and mix together until the coffee is dissolved.
    • Pour the milk/coffee mixture, vanilla essence and vegetable oil into the mug with the dry ingredients already in it. Mix until combined (do not overmix).
    • Fold in the chocolate chunks.
    • Microwave for 1 minute. Cooking time can vary depending on the strength of your microwave. Check your cake by poking a thin knife into it, and if it comes out clean it's done. If your cake needs a little longer, pop it into the microwave for another 10 seconds until done.
    • Garnish with whatever you like! I like putting some whipped cream on top. Ice cream or fresh fruit work great too 🙂

      After several tries of making mug cakes, this is the first one that actually came out moist yet done. Also this is the first one that rose and then set without deflating like a souffle. I used a 420ml large cup and it came up to about half full once done. I then added some caster sugar and a big ball of vanilla ice cream and it was delicious.
      Thank you.

      *I have a 700w microwave. I cooked it for 1 minute 10 seconds and it seemed done, but just to make sure I put it in for 15 seconds extra.

      Rich, moist chocolate mug cake – it’s the best recipe on the internet I tell you!! No more dry, under-chocolately half raw mess like the majority of recipes out there. This was simply perfect.

      I doubled the recipe (one for myself and my partner) and used 2 tbsp of chocolate chips (as mine are very small), and omitted the coffee (as I didn’t want any more of a ping in the evening!!). I microwaved for 1 min and 15 seconds, and topped it with a ball of ice cream – It was fabulous. Write this down in your cookbook so you don’t forget it, and pull it out whenever you’re craving cake in the evening!

      Delicious! This is the best Mug Cake recipe I have ever tried. It was tender, gooey and not too sweet. I cannot wait to make this again.

      love your recipes and wanted to try the double choc mug cake. Do I have to use coffee? My partner hates coffee. What alternate would you recommend? Thanks

      • Cakes by MK

        Hi Michele! So happy to hear you’re enjoying the recipes 🙂 and you can simply leave the coffee out if you prefer – keep in mind it doesn’t make the cake taste like coffee just enhances the chocolate flavour but some people who are more sensitive to coffee may still be able to taste it 🙂 enjoy!
