Galaxy Chocolate Cupcakes

Galaxy Chocolate Cupcakes

As I mentioned back when I made my Malteser Teaser Cupcakes, there are so many chocolate bars being turned into spreads at the moment. So I feel it is only my duty to then turn these spreads into buttercream to top delicious cakes and cupcakes with! This time it’s the turn of Galaxy Chocolate Cupcakes. I’ve infused the sponge with Galaxy hot chocolate powder, which by the way is my favourite hot chocolate powder and you must give it a try, it’s so creamy and rich for a powder drink. Then I’ve made a buttercream using the Galaxy chocolate spread, and of course the decoration had to be in the form of Galaxy chocolate pieces for the ultimate Galaxy triple treat!

Jump straight to the recipe!

For the sponge, I creamed the butter and sugar together, then whisked in the eggs and milk. Next I whisked in the self raising flour, baking powder and Galaxy hot chocolate powder.

I divided the batter between 12 cupcakes cases and baked them for 20-25 minutes.

Whilst the cakes were cooling, I made the buttercream by mixing the Galaxy chocolate spread with icing sugar, butter and milk.

I piped it onto the cupcakes using my Wilton 1M nozzle, then topped them with Galaxy chocolate pieces.

The Galaxy Chocolate Cupcakes were an absolute chocolate sensation! They disappeared in less than an hour when I took them into work.

Any Galaxy chocolate fan, or just chocolate fan in general, will go nuts for these cupcakes! I only added two Galaxy pieces to the top, but you could add three – I wish I added more!!

    Those cupcakes look soooo luxurious! The butter cream screams velvety chocolate! I think it’s great you’re talking on the task of turning new and exciting chocolate spreads into cupcake creations….it’s a difficult job , but somebody’s got to do it.

    Like you, Galaxy is my favourite hot chocolate powder. It is definitely the best and they also have a lighter version which makes me think I’m being healthy haha. These cupcakes look so delicious, the buttercream is so shiny and smooth! My father in law is obsessed with Galaxy and would absolutely love these!

    1. Yay, I’m so glad you’re also a Galaxy hot choc fan – it’s my absolutely favourite!

  3. Those cupcakes – that frosting! It just looks like I could reach right in my screen and sneak one! I wish I could! Thanks for bringing this by Fiesta Friday!


  4. Your cupcakes always look so dreamy Kat. I reckon you’d find it hard to get more Galaxy in there if you tried. I bet they were super delicious. Thanks for linking up with the final ever #WeShouldCocoa and for being a part of it for so long.

  5. I made your Nutella three tier cake, a huge success. I’d like to do the same with this recipe. Do you think doubling the quantities would work?

    1. I’m so glad you liked the Nutella Cake! No you wouldn’t want to double the quantities of this cupcake recipe. The best thing to do would be to use the same quantities as the Nutella cake, but replace the Nutella in the buttercream with Galaxy spread, replace the cocoa powder in the sponge with the Galaxy hot chocolate powder (or you could stick with cocoa powder), remove the hazelnuts, and decorate with Galaxy chocolate. Let me know how it turns out!

    May i know why the sponge receipt different compare to nutella cupcake? Whats is the purpose of the milk?

    1. I used slightly more of the hot chocolate powder than I did of cocoa powder in my Nutella Bueno Cupcakes and as cocoa powder/hot choc powder can dry sponge out I added the milk to combat this.
