Kopi Mug Cake – Coffee Mug Cake with a Local Twist

Kopi Mug Cake
Kopi mug cake – what’s there not to love about coffee and cake?

Many of us can’t get through the morning without that first cup of coffee, be it an espresso, freshly brewed coffee, a latte, or keeping it local and having a great cup of kopi – ‘si’, ‘peng’ or ‘o’. Well, how about we give you an excuse to have cake and coffee in the morning instead? All rolled up into one perfect cup of kopi mug cake. It’s the perfect breakfast!

Fluffy and warm with that necessary hit of kopi, our kopi mug cake is a breeze to put together and requires ingredients you probably already have stashed in your kitchen cabinets. Besides breakfast, it’s great as a late morning, afternoon, early evening or tea time snack, when you need a quick but absolutely necessary pick-me-up to help you get you through the day. And if you’re the sort that likes their coffee with something sweet after dinner (and won’t stay awake all night after that), this quick and easy recipe is one you need to include in your rotation. You can picture it, can’t you? Your feet up on the sofa, a new episode of your favourite show, and a warm mug of coffee-smelling goodness in your palms.

Or, making this delicious concoction in your office pantry, and carrying it to your desk while heads swivel in the direction of that mesmerizing aroma. Mmmm… We reckon this kopi mug cake is absolutely promotion worthy! Don’t just take our word for it though, you have to give our recipe a try. All you need is a microwave oven and the ingredients below. And if you need to take a trip to the supermarket to get them, we promise you, it’s absolutely worth it.



  • 1 tsp kopi powder
  • 2 tbsp milk

  • 1 ½ tbsp granulated sugar
  • ¼ tsp baking powder
  • 1/8 tsp salt
  • ¾ tbsp vegetable cooking oil + extra for oiling the mug

  1. In a separate bowl, add flour, sugar, baking powder and salt. Use a whisk to combine the ingredients evenly.
Dry ingredients
  1. Pour the steeped coffee through a fine sieve into the mixed dry ingredients. Don’t worry if a few bits of coffee powder gets into the mixture. Stir with a whisk until thoroughly combined.
  2. Next, add cooking oil and vanilla into the batter and stir with a whisk to mix through.
  3. Add a few drops of oil into a small microwaveable mug. You can either use a brush or a kitchen paper towel to spread the oil, covering all the inner surfaces of the mug. Alternatively, you can also use cooking spray.
  4. Pour the batter into your oiled mug.
  5. Microwave on high heat for 1 minute and 30 seconds.
  6. Let cool for a minute before serving.


Extra tips

  1. Use your favourite brand of kopi kampung for this recipe. If your kopi comes in sachets, steep 1 whole sachet in the milk and don’t forget to squeeze out all the liquid goodness before pouring the steeped coffee into the dry ingredients.
  2. Do not use three-in-one kopi sachets as it already comes premixed with sugar and creamer, which will throw the rest of the recipe ingredients off-balance.
  3. No kopi, only coffee? We’re not sure if it will work, but do give it a try and let us know. You’ll want fine coffee powder for the best outcome. Steeping coffee beans won’t get you much flavour in the short amount of time needed.
  4. Mild flavoured cooking oils work best for this recipe, such as grapeseed, canola or sunflower oil. Leave your olive, sesame or coconut oils for other recipes.
  5. Microwave mug cakes will harden and become tough and chewy once it cools, so be sure to eat it while it’s still hot!
  6. For extra decadence, serve with a scoop of vanilla ice cream or whipped cream. Or both!
  7. Not much of a kopi drinker but prefer teh tarik instead? Don’t worry, we’ve got you covered with our teh tarik mug cake recipe!

We're just a small group of friends who love food, culture and Malaysia. We saw the rise of mediocre food, deteriorating relationships and missed the good old days of Malaysia where food was good, homes were warmer and full of friends and family. So we rolled up our sleeves, and made Butterkicap with the hope that it will bring people and flavors home.
