Space Themed Birthday Cupcakes

My kids really wanted a space themed birthday party and although I love making cakes this time I decided it would be fun to go really simple and create some galaxy themed cupcakes for the kids to have instead of a big cake. Using our chocolate cupcake recipe I doubled the mix to make 24 cupcakes and decorated them with this really easy decoration just some swirled vanilla buttercream icing on top.

Galaxy Cupcakes for a Space Party for Kids

Both J and T love anything space related.

From asking to stay up in the garden late in the summer to see the stars to watching our favourite space-themed movies as a family including our long-standing family cinema date to see the latest Star Wars films.

So it came as no surprise that they wanted a space party. These cupcakes were so simple to put together and I was glad as I’m generally in a rush when it comes to parties as always think I have more time than I actually do.

Using a simple icing recipe and some extra sparkles these were perfect to make and the kids loved them.

Neon Food Colouring – I try and use Wilton gel food colouring for cake decorating. You need much less of it, it leaves no taste and the colours are really vibrant with just a little of the colour. The bonus is it’s also great to add to our Edible Playdough or in Salt Dough creations too!

Black Gel Food Colouring – instead of just buying black I have a set of Wilton gel food colours which includes black as one of the tubs. To be honest I haven’t tried other makes of gel food colouring as our local store only stocks Wilton so I’ve stuck with them!

Silver Edile Mist – this is one of my daughter’s favourite things to decorate cakes with. We have both the gold and silver spray and she always asked to sparkle up her cupcakes when we make them. Just a spray and they pop!

Edible Pearl Lustre Dust – Along with the spray above and edible glitter these little pots get used time and time again from adding sparkle to our Space Rock Buns to making our Princess Party Cupcakes shine.

Servings 24 cupcakes


  • 2 x Chocolate Cupcake Recipe See Notes for Link and Instructions
  • 227 g unsalted butter softened to room temperature
  • 375 g icing sugar
  • 3 tbsp. double cream
  • 1 tsp. vanilla extract
  • neon food colouring gels
  • black gel food colouring
  • silver edible mist
  • pearl lustre dust


  • In the bowl of a stand mixer, cream together the butter, icing sugar, vanilla, and double cream until combined and smooth and stiff peaks form
  • Divide the frosting up between 5 bowls.
  • Mix one colour into 1 bowl each and until combined. We find this easiest to do using a toothpick.
  • You'll need to add more black gel food colouring to get the black to be a darker shade for your space cupcakes.
  • Place the piping bag into a large glass and fold the sides over the edge to provide an easy way to fill the bag.
  • Using an angled spatula, scoop black icing onto 3 sides of the piping bag.
  • Alternating between the 4 remaining colours, scoop 2 tablespoons of the colour icing into the piping bag on the side you have left free of black.
  • Frost the cooled cupcakes using a star-shaped nozzle.
  • Lightly spray the frosting with the edible dust when finished.
  • Dip a small paintbrush into the pearl dust.
  • Using your finger, run it along the bristles of the brush to allow the dust to splatter onto the icing on top of the cakes.


Make 2 batches of our simple chocolate cupcakes and leave until fully cool before decorating with the vanilla icing.

Space Themed Birthday Party

We loved these Light Saber Balloons from Crystal and Co which we gave alongside a Pool Noodle Light Saber to the party guests instead of a party bag.

We made some edible moon rocks which tasted amazing!

And had lots of fun with some space-themed crafts.
