Yummy Galaxy Chocolate Cupcakes with a Chocolate Cupcake Sponge, Galaxy Chocolate Buttercream Frosting. GALAXY HEAVEN!

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? 

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!

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! 

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!

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. 

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.

    Hi, stupid question perhaps but if I wanted to half the recipe, how many eggs would I need to use?

    • Jane's Patisserie

      You can easily either do 1/3, or 2/3, but half is hard. A full batch uses three eggs, so you can’t really use 1.5 eggs.

      Ok, thank you. I tried the recipe today but used dairy milk chocolate instead of galaxy as I didn’t have any and it was lovely – thank you! x

    Hi Jane, could you please let me know whether this recipe would be suitable for a tray bake (30x20cm tin)?

      Hey – you can do, but the ingredients will change quite a lot – have a look at my G&T traybake for a guide of ingredient amounts.
