Neon Galaxy Cupcakes

These magic glow in the dark cupcakes are made with strawberry essence and a meringue buttercream frosting.


  • Cupcakes
  • 429g all-purpose flour
  • 265g caster (superfine) sugar
  • 3 tsp baking powder
  • 1/2 tsp salt
  • 125g unsalted butter, softened
  • 375ml of tonic water
  • 125ml vegetable oil
  • 2 tbsp Greek yogurt (can substitute with sour cream)
  • 1 tsp vanilla extract
  • 2 large eggs
  • 1 tsp strawberry essence
  • 5 drops pink food gel
  • 3 drops orange food gel
  • Jelly Glaze
  • 1 pkt clear jelly or blue jelly.
  • ½ cup boiling water
  • 1 cup tonic water
  • Frosting
  • 1 batch Swiss meringue buttercream frosting
  • 2 drops green food gel + 1 drop yellow food gel
  • 2 drops purple food gel
  • 2 drops blue food gel


  1. Preheat a fan-forced oven to 160C (320F) or 180C (356F) for a conventional oven. Line a cupcake tin with cupcake liners.
  2. In the bowl of a stand mixer fitted with the paddle attachment, add the flour, baking powder, caster sugar and salt. Turn mixer on low speed and allow it to mix for a couple minutes to help everything combine well (alternatively you may do this by sifting the ingredients together). Add the softened butter and let it mix until it resembles a fine sand like texture.
  3. Next, add tonic water, eggs, yogurt, oil and vanilla extract in a large jug and whisk well.
  4. Add wet ingredients to dry ingredients in a slow and steady stream until no dry ingredients are visible. Scrape down the bowl and mix for another 20 seconds.
  5. Fill each cupcake liner 3/4 of the way (using an ice cream scoop to transfer the batter into the cupcake liners makes this a quick and easy process otherwise you can use two tablespoons).
  6. Bake for 30-35 min or until a toothpick inserted comes out clean. Allow them to cool completely on a wire cooling rack before frosting.
  7. Frosting
  8. To prepare frosting split into three separate bowls. Colour one purple, one green with the green and yellow food gel and the other blue. Mix until well combined.
  9. Add each colour to three separate piping bags and snip a small bit off the end of each one.
  10. Lay a piece of plastic wrap on your work bench and pipe lines of the different coloured frosting on it. Then roll up and twist both ends. Snip off one end and insert it into a large piing bag fitted with a Wilton 1M piping tip. Frost a swirl of frosting on your cupcakes. Chill in the fridge until frosting is stiff. About 30 minutes.
  11. To make the jelly glaze add the jello powder to a medium sized mixing bowl and some hot water. Mix until completely dissolved. Then add Indian tonic water until mixed. Set aside at room temp.
  12. Once the cupcakes are chilled carefully dip into the jelly/jello glaze. Allow excess to drip off. Thaw before serving.
  13. Use a black light to make them glow in the dark!
