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,
    Love these cup cake but do u use a beater attachment or wisk attachment to make cake mix. Thanks Claire

    • Jane's Patisserie on June 2, 2021 at 9:44 am

      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!

    • Jane's Patisserie on April 13, 2021 at 12:27 pm

      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.

    • Jane's Patisserie on March 22, 2021 at 3:50 pm

      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?

    • Jane's Patisserie on March 3, 2021 at 8:10 pm

      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



  5. Grace Macdonald-cain on February 28, 2021 at 8:05 pm

    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.

    • Jane's Patisserie on February 28, 2021 at 10:06 pm

      Yes you can! X



    • Lauren on March 30, 2022 at 1:34 pm

      How cool does the melted chocolate need to be before adding it to the buttercream?



    • Jane's Patisserie on March 30, 2022 at 3:50 pm

      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

    • Jane's Patisserie on February 2, 2021 at 6:52 pm

      Yes!! As long as you double check all other ingredients as well obviously it works perfectly! 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.

    • Elle on July 28, 2021 at 1:22 pm

      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!



  8. Angie on January 5, 2021 at 9:57 pm

    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



  10. Ana Clara on December 8, 2020 at 6:32 pm

    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.

  12. 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?
