What is a mug cake?

Mug desserts are a great thing, you guys! Think of mug cake as a quick single-serving cake that’s whipped up in your mug and baked within minutes.

Usually in a microwave but you can also make this individual brownie recipe in the oven. These single serving desserts usually take only about a minute  or two to make, and the result is a moist vegan mug cake that is sure to satisfy your chocolate craving. Yay for easy recipes.

What’s not to love about single serving cake? Instead of having to make a whole batch of brownies you can now just make one single vegan microwave brownie to get that chocolate cake fix!

So incredibly convenient and so tasty! I don’t know about you but I usually only want a couple of spoons of dessert anyway and I find one cup of this is just enough to get that satisfying chocolate flavor and that divine fudgy texture.

Can I make this vegan brownie in the oven?

YES. If making in your oven, preheat oven to 350°F/180°C and bake in about a 3.5-inch ramekin (ensure it’s oven safe) for 25 minutes. Remove and allow to cool for about 5 minutes. Enjoy!

Can I make these gluten-free?

Yes, just use a gluten-free flour blend like 1-to-1 gluten-free baking flour by bob’s red mill

Sugar-free option: 

For making a sugar-free mug cake replace sugar with the same amount of erythritol and use sugar-free chocolate chips.

Why is my mug cake so spongy?

Oftentimes overmixing the batter is the problem! You might also have added too much oil to the batter or might have overbaked the cake.

This mug cake is best served immediately, straight away from the mug. You can also serve it flipped over a plate but it won’t look as beautiful.

Tips for making vegan chocolate mug cake:

  • I recommend you use a wide short-ish mug as this allows for the cake to rise higher.
  • Ensure to stir dry ingredients and wet ingredients together well. You don’t have to go whisking for minutes on end, just ensure your entire mug cake batter is smooth without any lumps sticking at the bottom.
  • You might want to adjust your baking time based on your microwave and maybe add an extra 10 seconds.
  • You want a fudgy vegan mug brownie so do not overbake these! Leaving your cakes in the microwave for longer than recommended will make your mug cake gummy and dry. It’s better to take them out a bit too early than too late. Remember that the mug cake will keep on cooking while it’s cooling so it’s better to slightly underbake it.
  • Let it cool for like 3 to 5 minutes before digging in. It really does make a difference, like how you’d let a cake or brownies cool first!
  • As a coconut lover, I like making these with melted coconut oil and coconut milk but any plant-based milk will do and melted vegan butter or any vegetable oil will lead to great results as well.
  • I add dark chocolate chips to the batter and sprinkle some more on top
  • The espresso powder helps enhance the chocolate flavor, and so does the salt so I recommend you don’t skip these additions

Prep Time 1 minute

Total Time 2 minutes
Servings 1
Calories 200 kcal


  • 1 tablespoon melted coconut oil or any oil of choice
  • 3 tablespoons non dairy milk any vegan milk works
  • 1/2 tsp espresso powder Instant
  • 2 tablespoons granulated sugar or a sweetener of choice I use cane sugar, you can use brown or coconut too
  • 2 1/2 tablespoons unsweetened cocoa powder
  • 3 tablespoons all purpose flour or gluten free flour mix*
  • 1/4 teaspoon baking powder
  • 1 big pinch sea salt
  • 1 teaspoon vanilla extract
  • 1 tablespoon dark chocolate chips


  1. In a mug, add in the oil, milk, Instant espresso powder, sugar or sweetener and cocoa powder. Whisk together for about 15 seconds. Add in the flour, baking powder, salt and vanilla extract.

  2. Stir to combine ensuring it’s all incorporated and that you get the bottom and sides scraped well too. Add in the dark chocolate chips and fold in. Feel free to sprinkle some of them on top.

  3. Place the cake your microwave for 65 seconds. Better to take it out 5 seconds too early than too late. It's okay if it's slightly undercooked in the middle because it'll continue to cook a bit while it cools down. No one minds a melty middle but everyone minds a rubbery cake. Remove and let cool for about 3 to 5 minutes for best texture.

  4. If making the mug brownie in your oven, preheat oven to 350°F/180°C and bake in about a 3.5-inch ramekin (oven safe) for 25 minutes. Remove and allow to cool for about 5 minutes. Enjoy!
