Easy and delicious chocolate mug cakes with a gooey centre that are ready in minutes!

Chocolate mug cakes

Hello chocolate mug cakes! So it’s an obvious thing if you read my blog, or look for recipes on here, that I adore chocolate… and cake. To be fair, I prefer cookies or brownies over cake in general, but sometimes thats just down to the fact that they’re easier to make. Therefore, I wanted to finally publish a recipe that is SO EASY that it’ll be rude for you guys to not try it. Honestly, six ingredients, no butter or eggs, and ready in less than five minutes.

I’ve tried several mug cake recipes over my time, as they’re just so easy. When you want a slice of chocolate cake, and you either don’t want to bake an entire one yourself, or you don’t want to buy one. Literally, whisking together some ingredients together and microwaving the mug cake, and huzzah you have a fudgey, chocolatey and delicious treat. I went for chocolate for my first mug cake recipe, but don’t worry… I will be posting plenty more as the time passes!

Serves one

I decided to make two of them for the photos to have a little more impact than just one.. but the recipe is designed for just one mug. Obviously, you have to make sure that the mug you use, that it can actually go in a microwave. I once tried to use one of my favourite mugs… but that went a little wrong. Let’s just say it had to go straight in the bin. But anyway, I used these cute mugs that I got from my local Starbucks, and they were the perfect size!

Raising agent

I tried this recipe with some baking powder, and it does work and make it more fluffy, but personally I wanted a denser and more gooey cake. You can add in 1/2 tsp of baking powder, but its entirely optional. I used self raising flour as I preferred it to plain, and then thats enough raising agent for me. The measurements are a difficult thing I find because peoples versions of ‘one tablespoon’ can vary in weight SO VERY MUCH so I have put weights as well. 15g is typically a level tablespoon weight, so don’t do heaped.. it might not turn out as good!

More chocolate?!

I did think that even though these cakes are so gooey already, that they needed a little more oomph. One of my favourite things at Easter was to add a frozen creme egg in the middle of the mug and it was so ridiculously yummy I couldn’t cope, but I never got round to posting it in time. So, as Easter is now long gone and all the treats are out of the shops again… I thought why not just use some actual chocolate?!

I thought I would make mine triple chocolate style by using a couple of chunks of milk chocolate, and then also some white chocolate chunks. When microwaving the cake, these melt as well, and it forms a gooey molten centre that you can devour.

Recipe adaptations

One of the best things about this recipe? It can so easily be made dairy free, and vegan. Honestly, I’ve tried several vegan versions, and they’re just as good. The first time I started making these I was attempting to be dairy free to see if I had an intolerance, and I was heartbroken I couldn’t have one. However, soon after realising I already didn’t include butter, and my cocoa powder is dairy free… why not try a different milk?!

I used almond milk and it heated up and ‘baked’ in the exact same way as the whole milk. Also, the chocolate chunks in the centre can easily be made vegan by using dairy free dark chocolate (which to be honest is most dark chocolates these days!)

Top tips!

Be careful when making these with your microwave as well. Microwaves can vary in power, so my guides for timing can be different for your own. It’s worth giving one a go, and you’ll be able to adjust yourself from there. If you’re doing more than one at once, they will take longer than just one on its own, so be wary of that as well! For the two in these photos, it took 100 seconds. For just one, it took 60 seconds. I hope you love these as much as I do! Enjoy! x

Category: Dessert
Type: Cakes
Prep Time: 2 minutes
Cook Time: 2 minutes
Total Time: 4 minutes
Servings: 1 Mug Cake
Author: Jane's Patisserie

Ingredients

  • 45 g self raising flour (3 tbsp)
  • 30 g caster sugar (2 tbsp)
  • 15 g cocoa powder (1 tbsp)
  • 1 tbsp sunflower oil
  • 4 tbsp whole milk (Or almond milk)
  • Chunks of chocolate

Instructions

  • In a mug, add all the ingredients, apart from the chunks of chocolate. 
  • Add in a few chunks of chocolate into the middle. I used two pieces of white, and two pieces of milk chocolate. 
  • Microwave for 60-90 seconds. And enjoy!

Notes

  • My microwave is an 1000watt microwave, and my mug cake only took one minute to do on full power. 
  • If you want to do more than one, add on 30 seconds or so if microwaving at the same time. Mine took about 100 seconds to do two. 
  • You can EASILY make this vegan, by using dairy free dark chocolate in the middle, and using almond milk. 
  • Sometimes it can look a little gooey on top, or round the edges, but it is done!
  • You can easily mix everything in a bowl, and simply pour into a mug to bake in the oven. 
  • You can add in 1/2tsp baking powder if you want it to be more light and fluffy, but it can raise up a lot more and explode over the edges!

    Great texture for a mug cake. I used only 1tbsp of sugar and it was sweet enough for me. Pretty good with a dollop of creme fraiche on top.

    Just tried out this recipe as a bit of comfort food as I’ve been unwell. I really fancied a mug cake, and hadn’t made one in years so couldn’t remember which recipe I used to use. I found this one and it was delicious! I only had semi skimmed milk so used 2 tbsp milk & 2 tbsp single cream (I had a little cream left over in the fridge that needed used) I also added an extra tbsp of milk after reading comments from others that they had added extra milk. I used a few cubes of dark chocolate (also left over that needed used up) More than the recipe says, 8 squares of Bournvilke chocolate) I heated it in short bursts and after 80 seconds it was done but still very “saucy” and gooey which I was hoping for. Poured over another dribble of the left over single cream and tucked in! It was so good! And not overly sweet as I used dark chocolate. Thank you. It was just what I needed feeling poorly on a cold snowy day in Scotland! Great recipe xx

    Too much self-raising flour, and how can 3tbsp be worth of 45g? I did this recipe and I used 45g and it came out to be 4tbsp and in the end it barely rose and came out too hard. I used skimmed milk instead of whole, but I don’t think that is the issue. I don’t know if it is just me but I don’t think this came out right. Any tips, Jane?

    • Jane's Patisserie on December 3, 2024 at 12:47 pm

      15g = 1tbsp typically, so it’s 45g. However, if you don’t fill a tbsp firmly it can seem like more. The measurements are correct in the grams however, but skimmed milk doesn’t have any fat content so that will have caused a problem x

    Only mug cake recipe I use! Just make sure the first time you do you try with the shortest possible time and go from there. Easy to overcook by as little as 10 secs in microwave .
    10/10 recipe would recommended.

    • Marion on February 24, 2025 at 4:20 pm

      I do not have self raising flour. How much baking powder is added to regular flour for this recipe? How long does it bake in the oven and what temperature? Thanks you.

    A perfect recipe!
    I made this with chocolate chips and put a dollop of nutella on top, it took about 80 seconds in my 700w microwave and came out perfect!
