Chocolate Fudge Cupcakes!

Easy, Delicious and super Insane Chocolate Fudge Cupcakes with the Ultimate Chocolate Buttercream Frosting! 

So the time has come, to morph my Chocolate Fudge Cake into the very sort after Chocolate Fudge Cupcakes! Honestly, this has been SO requested that I apologise that it’s taken so long. These are the most incredible cupcakes, so here they are! 

From the start I will say that these are quite a bit more intense than the classic ‘Chocolate Cupcake’. If you are after something delicious, but easier and more basic, then check out my Chocolate Cupcakes recipe! They’re more chocolate Victoria sponge based, whereas these beauties are intense and wonderful.

The Dark Chocolate in the cake sponge is part of what makes it so fudgey, so PLEASE don’t switch it to milk chocolate. If you don’t like dark chocolate, these probably aren’t for you… but if you like a rich and delicious chocolate cake, then you are in luck.. because they are INCREDIBLE. 

This sort of cake mixture is a lot thinner once you have made it, in comparison to a normal cake batter like a chocolate Victoria sponge. When I make it, I really just use my hand and a whisk and a spatula… there is no need for an electric mixer with this cake! Yeah you need three different bowls, but its 100% worth it! 

Melt the Chocolate and Butter, add in the Coffee, whisk all the dry ingredients together, and whisk the Eggs, Vanilla and Buttermilk together and you have a cake! The best thing I did for this sponge was to bake the full cake at 140C Fan, so I stuck with it for these cupcakes. It does mean that they take longer to bake, 30 minutes in reality, but it makes them so ~moist~ and soft. 

For the Frosting, it’s just basically a cocoa powder buttercream frosting, but mixed with evaporated milk. This is basically all that makes it special, but IT IS WORTH IT. I tend to buy the mini tin size, so as there isn’t as much wastage, but with this recipe there is about half a tin left. I then use it up in another batch of cupcakes or use it in another recipe!

For the Buttermilk, it’s worth buying (or making), but if you have any leftover, make some buttermilk scones! HEAVEN. Especially if you spread some of the frosting on, because it is just honestly the best and I would eat it with a spoon. All day long. 

I hope you love these seriously fudgey and delicious Chocolate Fudge Cupcakes, as they are my new favourite. ENJOYYYY! xxx

For the Cupcakes!

  • 100 g Dark Chocolate
  • 100 g Unsalted Butter
  • 1 tsp Instant Coffee
  • 75 ml Boiling Water
  • 100 g Plain Flour
  • 20 g Cocoa Powder
  • 1 tsp Baking Powder
  • 200 g Light Brown Sugar
  • 2 Medium Eggs
  • 75 ml Buttermilk (or soured cream)
  • 1/2 tsp Vanilla (optional)

For the Frosting!

  • 150 g Unsalted Butter (room temp - not stork/spread)
  • 300 g Icing Sugar
  • 35 g Cocoa Powder
  • 1/2 tsp Vanilla (optional)
  • 75-100 ml Evaporated Milk


  • Sprinkles


For the Cupcakes!

  • Preheat your oven to 160C/140C Fan, and get your cupcake cases ready. 
  • In a microwave proof bowl, add your Chocolate and Butter and heat and mix until melted. I usually do 30 second bursts! 
  • Pour the Boiling Water onto the Coffee Granules and mix till smooth - add the Coffee mix into the Chocolate/Butter mix until smooth. 
  • Add the Flour, Cocoa Powder, Baking Powder and Sugar to a large bowl and whisk till distributed. 
  • Mix together the Buttermilk, Eggs and Vanilla. 
  • Add the three mixes together - I pour the Chocolate/Coffee mix and the Egg/Soured Cream mix into the dry ingredients and fold until smooth. 
  • Split the mixture evenly between the baking cases. I use Regular Baking Cups from Iced Jems, and I fill them 2/3 full.
  • Bake in the oven for 28-32 minutes, or until baked. 
  • Leave to cool fully once baked!

For the Frosting!

  • Make sure your Butter is at room temperature!
  • Beat the Butter on it's own for a few minutes to soften!
  • Add in the Icing Sugar and Cocoa Powder 1/2 at a time, and beat till combined.
  • Add in the Vanilla if using, and then the Evaporated Milk a little at a time beating fully in-between each go!


  • Pipe onto your cupcakes how you please! I used a Medium 2D Closed Star Piping Tip. 
  • Sprinkle on your favourite sprinkles and enjoy!

    Hi Jane,

    Apart from the flour would there be anything else in these cupcakes that wouldn’t contain gluten

    • Jane's Patisserie
      February 16, 2021 at 8:01 pm

      You would need to double check all ingredients you buy as brands can vary – but it should just be the flour.

    Hi Jane! How would this batter react in a mini bundt tin? I want to make some mini chocolate bundts and the recipes I’ve tried so far haven’t given a soft, fudgey enough result yet! Thanks

    • Jane's Patisserie

      I think as long as you have a really good release spray/paste on the mould, they would be fine!

    Incredible recipe! Will be definitely making again and they were incredible well received by my housemates. I could slightly taste the coffee the first day, however cakes I ate on subsequent days didn’t have this taste (perhaps they were still slightly warm the first time which may have made a difference? I also used decaf coffee as this is all I had so perhaps this made a difference). The coffee taste had definitely gone by the following morning though and they were delicious! Will definitely make it into my regular rotation of baking recipes!

    Hi jane,
    Can i use oil instead of butter in the cupcakes? Or it will completely alter the recipe?

    • Jane's Patisserie
      December 10, 2020 at 10:13 am

      I would stick to the butter personally because of the method and how it all works together.

    Hi Jane,

    I made these for my friends birthday and they were delicious. Is there any way to use different flour to make them gluten free?

    • Jane's Patisserie
      December 10, 2020 at 10:16 am

      I’m sure switching to gluten free flour would be fine, and maybe adding 1/2 tsp xantham gum if you have it!

      I wouldn’t recommend it. It’s important to follow the recipe as it is x

    These had a wonderful flavour. Only issue was the tops of my cupcakes turned out like brownies – that thin meringue crisp layer that we all strive for in brownie making! – but wasn’t ideal for the cupcakes as the frosting would not stick properly the actual cupcake. Wondering if this is as a result of the temperature of the chocolate mix being too hot when added to the dry mix with the sugar? When brownie making i add the sugar to the chocolate butter mixture when it’s still hot, which gives me my crinkly tops so perhaps it’s the same thing here… In the end I just ate them all I frosted and the chocolate flavour was unbelievably rich which you don’t often get in a chocolate cupcake without frosting!!

    • Jane's Patisserie
      November 5, 2020 at 3:32 pm

      The melting of the chocolate for this is different to my brownie method (Where the chocolate does cool) but yes it most likely is the heat, or even over mixing! x

    Would this recipe be okay for making marble cupcakes? ( Just halving the ingredients for each batter and omitting the cocoa in one and replacing with flour )

    • Jane's Patisserie
      October 26, 2020 at 5:33 pm

      As the recipe uses melted chocolate as well as the cocoa and coffee, and they are both quite key to the recipe that wouldn’t be possible with this mix. It’s best to use a standard sponge (I do have a marble cupcake recipe on my blog) x

    Hi Jane!

    I have made so many of your cupackes nad they are simply delish, my work colleagues adore me for it!

    I was thinking of doing a dark chocolate cupacke and I was looking at this recipe and your white chocolate recipe, do you think this chocolaate cake with dark chocolate chips and a dark chocolate buttercream would turn out nice? maybe melted dark chocolate in the crem or would that be too heavy? Also how do you make the coffe for this? like how much coffe how much water? any sort of coffe or a particuler one? Sorry for all the questions!

    Thanks x

    • Jane's Patisserie
      September 24, 2020 at 9:18 am

      This cake batter is too thin for chocolate chips, and I don’t think they need it anyway as they are such a lovely deep flavour already. The details for the coffee are on the recipe! xx

  • Claire

    What would you suggest as a dairy free alternative for the evaporated milk?

  • Teyanne

    Hi Jane,
    Would this buttercream recipe work to cover the sides and top of the chocolate fudge cake if I’m doing 3 x 20cm tin layers? Or would I need more?

    Hi Jane,

    LOVE the flavour of this recipe it’s amazing, thank you!

    I did notice a big whole in the bottom of a lot of my cupcakes though which from the bottom looked like a big dome missing. Absolutely gutted – what did I do wrong?

    Thank you 😊

    • Jane's Patisserie
      August 28, 2020 at 7:23 pm

      That’s so odd – I’ve never seen it before! I can only assume it had too much air in the mix?! Or wasn’t baked for long enough? x

  • Kate
    August 8, 2020 at 11:36 pm

    Can’t wait to try this recipe, just wondering to know if you can use condensed milk instead of evaporated milk. If so how much should i add to the frosting?

    Thank You!

    • Jane's Patisserie
      August 9, 2020 at 12:26 pm

      They really aren’t the same and it doesn’t have the same results – I would just use double cream if you can’t use evaporated! x

    Hey Jane, I’ve just made the recipe and was just wondering and they supposed to come out of the oven when a toothpick comes out clean like normal cupcakes of if they should still be a little liquidy as once the 30 minutes were up mine still were xx

    • Jane's Patisserie
      August 8, 2020 at 8:32 pm

      They certainly should not take that long unless the temperature in the oven is wrong, you’ve changed an ingredient, or the cupcakes are larger than mine (as cupcakes really don’t take too long to bake at all!) – however, yes a skewer should come out clean! x

    Have made these during lockdown for a few occassions – husband’s birthday, cousin’s 40th and a family picnic. They are absolutely delicious and so easy to make. I’ve made them with the choc fudge icing and the peanut butter icing from the Reese’s cupcakes recipe. Loving this website!

    These cupcakes are so yummy. In the frosting I incorporated nutella and cocoa powder and it was mouth watering. For some reason I only had enough batter to make 11 cupcakes.

    • Jane's Patisserie
      July 10, 2020 at 4:08 pm

      That just means you have split the mixture between too few cupcakes or your cases are larger – it definitely makes 12! x

    I made these and they tasted delicious! Unfortunately when they came out the oven they shrunk away from the cupcake cases as they cooled, maybe my cases were too big.
    My only problem was my icing was too liquidy to pipe with, I do follow the recipe exactly- so better luck with my next bake!

    • Jane's Patisserie
      June 29, 2020 at 7:33 pm

      So shrinking away usually means the cupcakes haven’t finished baking yet, so the moisture causes them to peel away! And what butter did you use for the buttercream?

    My friends and family absolutely loved these!! The buttercream is sooo good.
    I hate coffee with a passion so I was wary but you definitely can’t taste the coffee at all!
    Also I couldn’t find buttermilk or sour cream in the shops so I made my own buttermilk and they still turned out amazing!

    Hi Jane, I hope you’re well! I’ve made this recipe before and it was DELICIOUS! I’m wanting to make it again but I’m really struggling to find light brown sugar anywhere! I found some light brown muscovado sugar, would that work or not?! Thank you

    • Jane's Patisserie

      Muscovado sugar should work fine, but golden caster sugar or regular caster sugar also works well!

    Hi Jane, just wondering if you have any preference on cocoa powder at all, whether some work better than others? I was looking online at Hershey’s, although a little more expensive I quite liked the idea that it is just cocoa and doesn’t go through other processes some do, have you tried Hershey’s in any recipes? Thanks in advance. The cupcakes look scrum, I’ve never thought of adding evaporated milk before & must give it a go! x

      Im a cake maker and Ive used this recipe a few times for my cupcakes and customers loven them. Although i tried tripling the ingredients as i needed to make 36 cupcakes and the batter was more runny than when i only doubled it🤷🏻‍♀️ They also were slightly crispy on top. And the batter had alot of lumps as i was only folding thru rather than using the mixer? They tasted ok but not as good as before trys🤷🏻‍♀️

    • Jane's Patisserie
      June 19, 2020 at 7:26 pm

      Tripling is quite a lot of mix – so you probably won’t have mixed it correctly, especially if you still had lumps. x
