Yummy Galaxy chocolate cupcakes with a chocolate cupcake sponge, Galaxy chocolate buttercream frosting. GALAXY HEAVEN!

Galaxy chocolate cupcakes
Galaxy = yum. Chocolate = yum. Cupcakes = yum. Galaxy chocolate cupcakes?! Oh holy moly yum! I just can’t really cope with how good they are. Like, I am so proud of the photos of these cupcakes, because I think it shows how good these cupcakes are.
I thought these cupcakes deserved a good start, and that paragraph I think sums them up nicely. I am obsessed with them. They’re delicious, so chocolatey and heavenly. How many times can I say that before it gets boring?! Honestly?


Cupcakes
Anyway… the cupcakes. I decided to use my standard brown sugar chocolate cupcake sponge. It’s an easy basic sponge, plus cocoa powder. They’re still light and delicious, and I use them in so many recipes – including my Toblerone cupcakes!
If you wanted a richer and more indulgent cupcake mix however – I one hundred percent recommend using my chocolate fudge cupcake recipe. They’re gooey, so fudgey, and purely epic. However, I understand that not everyone wants to go through that faff of the recipe, so I went for a basic on for these bad boys!


Baking cups
As usual I used my all time favourite baking cups from Iced Jems. The good thing about them is that they’re so easy to use, and she sells so many of them there is always ones to suit your theme! I used the brown polka dot baking cups as the brown colour fit the chocolate theme!
Chocolate
Like me, you can put some chopped galaxy throughout the cupcake – but its completely optional. You have enough galaxy in the buttercream and decoration that you definitely don’t need it – but I just love going a little overboard on a flavour theme! As you all well know…


As you can get the darker galaxy collection now, I used half of that and half of the regular galaxy in the buttercream frosting, but either work perfectly. It’s why the buttercream frosting is slightly darker – but don’t worry.. it tastes perfectly like Galaxy still!
Piping
I used my favourite 2D closed star piping tip for the frosting – as I am just obsessed with the swirl it creates. a 1M open star piping tip also works really well though. I always use ‘medium’ size piping tips in general, apart from a couple which are large.


I sometimes get comments saying how are my swirls so good, when others come out looking a bit like spaghetti, and that’s because a lot of piping tips that are sold in places such as supermarkets are much much smaller than the ones I use.
Decoration
For the decoration I use a couple of chunks of galaxy chocolate, a galaxy counter, and my favourite bronze crunch sprinkles. I was going to do a drizzle of galaxy chocolate… but I might have eaten the spare required for that job. My bad.
ENJOY THESE BEAUTIES! x

Hi Jane! I was wondering if you can making this recipie using galaxy caramel chocolate? If so would you recommend using it in both the cupcake batter and the frostings or just inside the batter? And would you use the same amount? Thank you!
Hi, I’ve been asked to make a galaxy choc birthday cake next week and love your recipes. I can only find the cupcake recipe. Could I adapt this to make one big cake?
How do I make this recipe into a cake? I want to make it as a birthday cake thanks xx
Hi Jane if I’m making it with my 4 year old sister ,can I add food die and if I do how much would I us in the buttercream?
Thank you very much 🤗🤗
Hiya! You can give it a go – however it may be slightly tricky as the buttercream is chocolate so you won’t be starting from a white base! Hope this helps! x
Hi jane. Ive had a go at these cupcakes today but the buttercream was extremely oily. I worked out it was probably due to my butter being way to soft as it is a hot day. I tried adding more icing sugar to try dry it up as adiviced on google search with no luck so tried putting it in the fridge for few minutes (15 to be precise) with also no luck. It was also hard to get the right consistency for piping any tips would be much appreciated. Thanks
Hiya – what exact butter did you use? Sometimes if it does become too warm this can happen. It may have needed slightly more chilling time, and then re-beating again x
Hi I made this recipe and My icing was a lot paler than yours, why would this be? I followed the recipe exactly xx
Hiya! In the blog post, I note the I used part regular and part dark Galaxy, so that would be why! Hope this helps! x
Hello! Love all your recipes. I am looking at making these but instead miniature cupcakes (like canope/bite size).
How many mini cupcakes do you think this recipe would make and how long would they need to be in the oven?
Thank you!
How long should I wait to add the melted chocolate to the buttercream? So excited to make these!
Hi Jane,
I love this recipe so much, I’m looking to use it to make an 8 inch cake, how many times would you say I should increase the recipe by? Thanks
Usually one batch of cupcakes = 1 8″ cake baked for 30 minutes! Or, use ratios from my layer cake recipes! x
can i make these galaxy cupcakes into gluton free
Hi Jane
With the stork butter for the cupcakes do you leave it at room temperature or can you use it out of fridge?
Thanks Claire
Hey, for the sponge it can be out of the fridge x
Hello Jane! Would you be able to use another chocolate like dairy milk or lindt for the sponge? Thank you and have a nice day 🤍
Hey! Yes most should work, thank youuu and you xx
Hi Jane,
Love these cup cake but do u use a beater attachment or wisk attachment to make cake mix. Thanks Claire
I always use a beater to make cupcake batter and buttercream, never the whisk x
I was scrolling this afternoon looking for a quick cupcake recipe to make with my children and came across these beauties!! Really easy to make and taste super delicious and I haven’t put the topping on yet!
Hey! Yayy I am so pleased you all enjoyed them xx
Hi Jane, what cocoa powder do you recommend for your chocolate cakes? I wouldn’t want the rich creaminess of the galaxy chocolate to be taken away with an over powering bitter cocoa powder.
I use Barry cacao 100% – but I find it is delicious so doesn’t over power x
Hi Jane, I made these for a friend and they went down really well. My question is how do I adapt the recipe for a 10″ square cake tin? Would I be able to adapt the galaxy buttercream to a fudge cake frosting?
Hiya! So I normally say one batch of cupcakes makes 1x 8″ round cake – so a 10″ square I would actually double the recipe (not sure on bake time though but maybe like an hour at 150fan? x
Hi I’ve made these before and making these again now. But I don’t have any galaxy chocolate for the buttercream could I make this with normal milk chocolate? Hopefully you will seen this soon. Many thanks.
Yes you can! X
How cool does the melted chocolate need to be before adding it to the buttercream?
Hiya! Your chocolate should be at room temp before adding it to the buttercream. Hope this helps! x
Ive these for my kids a few times now and they love them….can i make them gluten free by changing the flour and using xantham gum? Would it work ok? Thanks Gill
Yes!! As long as you double check all other ingredients as well obviously it works perfectly! x
