Feel like a quick treat without the fuss? This double chocolate mug cake has you covered. Taking only 1 minute to cook in the microwave, and bursting with flavour, this will be your new go to cake!

What makes this chocolate mug cake the BEST EVER?

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!

Double Chocolate Mug 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
- 1½ 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 🙂
