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

    My dad isn’t a huge chocolate fan but he does enjoy a galaxy chocolate bar. I made these for him for Fathers Day and he was very happy with them.

      Hi. I doubled the buttercream mixture to decorate a cake. Added 1 tablespoon of boiling water and the buttercream separated. What did I do wrong? I normally would use milk in buttercream but used water this time and it was a disaster!

    How can I change the ingredients to cake a birthday galaxy cake rather than cup cakes

    • Jane's Patisserie on January 6, 2021 at 9:51 am

      I usually say one batch of cupcakes makes one 8″ cake that takes about 35 minutes to bake x

    Jane, I don’t know what I’m doing wrong, my buttercream on these is so much lighter than yours every time I make them. Can I substitute some of the icing sugar for Cocoa to make it darker? Would 20g do it?

    • Jane's Patisserie on December 27, 2020 at 9:35 am

      You can do, but all photos will look a bit different to the end result, and as mentioned I used some of the darker collection in the buttercream as its what I had so that will have done it. x

    I loved the recipe, I really like brown sugar but I never tried it on the cupcake. I will make the recipe and it will surely be successful !! Thank you!

    Hi Jane,
    I was wondering if i could leave out the galaxy chunks since i just want a plain chocolate cake recipe.

  6. Sam on October 21, 2020 at 8:51 pm

    These look amazing!
    I want to make this into a birthday cake tomorrow in 3 9 inch tins would I still just triple the recipe and do you have an idea how long I would have to cook for thank you!!

    • Jane's Patisserie on October 22, 2020 at 3:14 pm

      Unfortunately I don’t usually bake 9″ cakes so I am insure on timings I am afraid, but yes I would say at least triple it, maybe even x4?



  7. Liza on October 13, 2020 at 6:15 pm

    Hi Jane recipe looks amazing! I was looking to bake these but in a 3 8inch cake tins. I was wondering would I need to triple the ingredients please? If yes would that also be for the buttercream if I was to cover the sides and have inside too please? Thank you xx

    • Jane's Patisserie on October 13, 2020 at 9:48 pm

      Yes tripling would be good – bake the layers for about 35 minutes! And 3x buttercream would be good! x



    • Liza on March 15, 2023 at 6:26 pm

      Hello I am looking to make this into a cake version but only have large eggs.. How many should I use please if making into a 9 inch cake? X



  8. Gillian on October 7, 2020 at 3:59 pm

    Hi Jane!

    I’ve just made these cupcakes, haven’t tried them yet but they look good. 🤞🏽 Just wondering if I can save the leftover buttercream? If so, how would I store it?

    There is so much left over I just can’t bring myself to throw it away. Not too sure why so much leftover, though I’ve a feeling it’s because I’m so rubbish at piping cupcakes! 🤦🏼‍♀️

    • Jane's Patisserie on October 8, 2020 at 9:42 am

      You can keep buttercream in the fridge for two weeks, or freeze for three months! Both ways the buttercream needs bringing back to room temperature and then re-mixing! X

    Hi, I love all your recipes! What if you only wanted to make 6?

    • Jane's Patisserie on October 5, 2020 at 12:11 pm

      You can try and half the recipe but because of the eggs I usually say it’s easier to use 2/3 of the recipe (so a two egg mix) and just put a bit more mix in each cupcake, or have 1-2 spare cupcakes!

    Fabulous recipe, thank you! I used a mix of galaxy and the darker galaxy for the icing and it was yummy!
    Also I didn’t have any brown sugar so just used caster sugar and it still worked well 🙂
    Just wondering, with the chopped galaxy in the cupcake, how finely do you chop?

    • Jane's Patisserie on August 3, 2020 at 2:25 pm

      I chop don’t chop the pieces that finely really, about 1cm pieces I guess?!



  13. Rohini Takhar on July 25, 2020 at 11:12 am

    Hi Jane I was wondering if you have a recipe using fresh cream instead of butter cream that would still give me the effect you have for the galaxy cup cakes. My family aren’t keen on butter cream.
    Thanks

    • Jane's Patisserie on July 25, 2020 at 2:17 pm

      Just whip 300ml double cream with 2tbsp of icing sugar!



  14. Sam on July 4, 2020 at 11:17 pm

    Hi Jane, if I just wanted to make 4, what would be recipe? Like how many eggs etc? Xx

    • Jane's Patisserie on July 5, 2020 at 11:31 am

      Use 1/3 of the recipe – so one egg!



  15. Chanel Phillips on July 3, 2020 at 2:49 pm

    Could i use Galaxy Carmel for inside the cupcake and for decoration? xx
