Some of you may or may not know that I am a household of one! And since I love making lots of cakes and treats, my freezer (and neighbors) see a lot of leftovers. Enter the craving-saving, fudgy, fluffy, moist one-minute chocolate mug cake for one!
Single-serving desserts are pretty much a lifesaver for my freezer and my waistband.

Plus, and this is a big plus, this easy mug cake recipe is practically effortless! Shove everything in a mug, mix, and microwave – I mean, could it get much simpler than that?

Within this post I’ll take you through how to make a mug cake, the ingredients, top tips, ingredient substitutions, as well as serving suggestions and more.
The Ingredients & Substitutions
All you need for this vegan mug cake is a few simple ingredients that you may already have in your pantry right now. Plus, as you’ll see – there are plenty of ways to adapt the recipe to what you have to hand.
- Whole wheat flour
- Baking powder
- Unrefined brown sugar – or a sweetener of your choice
- Cacao powder – or cocoa powder
- Coconut oil – or another neutral oil
- Plant-based milk – I used homemade oat milk.
- Vanilla extract – really helps ramp up the flavor
- Salt – a pinch of salt is all that is needed to bring out the chocolate flavor even more.
- Chocolate chips (optional)
When it comes to ingredient swaps, there are tons that you can make, for example:
- The Flour: You can use plain flour instead of whole wheat. You can also use a GF flour blend – unfortunately, I can’t guarantee the results as I haven’t tried each blend. You may also have success with oat flour.
- The Sweetener: My recipe is already unrefined. However, you could also try to swap it out with a sweetener of your choice (erythritol, coconut sugar…) and adjust the amounts. Liquid sweeteners (maple syrup, agave, rice syrup) will also work but may result in a more gooey cake.
- The Oil: You can substitute the coconut oil for a variety of neutral oils such as vegetable oil, canola oil, etc. Vegan unsalted butter should also work well.
- The Plant-based Milk: I used oat milk but almond milk, cashew milk, soy milk, rice milk, etc. will all work. In fact, you can even use vegan chocolate milk or coffee-flavored milk.
Bonus Ingredient Swaps:
- Instead of using plant-based milk, you could experiment with using black coffee for a mocha mug cake option.
- Plus, for a healthier cake, you can swap out the oil for applesauce and reduce the amount of sweetener used!

Learning how to make a mug cake is possibly one of the easiest ‘treats’ that I could possibly show you. All that’s required is mixing the wet and dry ingredients, chucking it in a microwave-safe mug, and microwaving!
Note: You can do this process in a separate bowl and then pour into the mug, or for less washing up, simply prepare the entire dish in the mug.
First, mix the dry ingredients into a microwave-safe mug/bowl.
Then, either mix the wet ingredients in a separate bowl before pouring into the mug or pour directly into the mug to mix. Mix well with a mini whisk or spoon/fork, to thoroughly combine. You want a smooth, lump-free batter.
Note: If you want to make it extra chocolatey, you can add extra chocolate chips (or dark chocolate) into the wet ingredients – just melt it quickly in advance.
Add part of the chocolate chips and stir them into the mix. Then sprinkle the rest on the top of the cup.
Microwave on high for 1 minute (my microwave’s high power is at 900W). If you prefer a slightly ‘underdone’ lava middle then you could try to microwave it for 40-45 seconds initially. If you find that your cake needs a little longer even after 60 seconds then place back into the microwave for a further 10-second burst.
Be careful not to overbake the cake though.
Best served immediately.
While I haven’t personally tried to do it this way, I can’t see why you can’t bake this chocolate mug cake recipe in the oven instead.
Simply make sure that it is in an oven-safe dish, like a ramekin. Bake in the oven at 180ºC/350ºF for between 10-15 minutes. You can check to make sure that it is cooked through with a toothpick or skewer.
I’d suggest watching it quite carefully after the 10-minute mark though as over-baked mug cake isn’t great.
Since I’m all about the effortless dessert here, there is nothing wrong with serving your chocolate mug cake as-is, from the microwave. However, if you’re wanting to elevate the dish even further then you could serve with some coconut whipped cream, a scoop of vegan ice-cream, or even a handful of berries or berry compote – Delish!
Unfortunately, I wouldn’t recommend trying to prepare the batter in advance. This can lead to cakes that don’t rise properly and, in general, just don’t seem to microwave very well.
Luckily, this recipe takes just minutes to throw together, so making mug cakes fresh is the way to go!
You could add a few blueberries or raspberries to the vegan chocolate mug cake batter. This will likely make the cake wetter, with more of a ‘lava’ cake effect.
You could also spoon in some nut butter to the center of the batter – such as peanut butter, almond butter, or even Vegan Nutella.
For a chocolate caramel swirl then simply spoon in some vegan caramel, or use the nut-butter based caramel from this recipe.
Add a few drops of natural flavoring such as peppermint oil or orange oil to boost flavor further for your vegan mug cake.
Add a spoonful of crushed walnuts or other nuts, if preferred, or even some shredded coconut.

To Make It In The Oven
- Simply make sure that it is in an oven-safe dish, like a ramekin. Bake in the oven at 180ºC/350ºF for between 10-15 minutes. You can check to make sure that it is cooked through with a toothpick or skewer.I'd suggest watching it quite carefully after the 10-minute mark though as over-baked mug cake isn't great.
- Make sure to stir/whisk the chocolate mug cake batter thoroughly. Otherwise, you may end up with little pockets of flour or flour at the bottom of the microwave mug cake- which no-one wants!
- If you have issues with the mug cake spilling over at all, then simply use a larger mug/dish.
- You can (optionally) grease your mug, to avoid any sticking. Though I tend to skip this step.
- Microwave cook times may vary depending on the make and model of your microwave. For my own microwave, I’ve found that 45-50 seconds yields a slightly gooey center still (which some may prefer). Whereas 60 seconds seems to be the perfect amount to be cooked, without being overcooked.
