Bubblepop Electric Cupcakes

Published: Updated:

Bubblepop Electric Cupcakes! These are the real freaking deal guys. This single cupcake is what launched The Scran Line. Now, a word of warning. These aren’t easy to make. So just know that before you make them. What makes them hard to make is the gelatine sphere. It can take a bit of practise before you can get it right. And no, before you ask, you cannot add sugar or flavouring into the gelatin ball to make it edible. No matter how it may taste, it will feel like you’re eating plastic. And a final note: this is a cupcake that takes a couple days to make. You need to let the gelatin balls dry properly for a couple days.

Pink Gelatin bubbles (make a couple days before)

  • Attach blown up balloons to paper straw or cake pop sticks with tape. Gently coat each balloon with a little oil spray over each balloon and wipe it down with a paper towel.
  • Add water and gelatin to a microwave sage bowl. Mix until well combined. Allow it to bloom (rest) for 5 min before you place it in the microwave for 10-15 seconds, or until melted. Add pink food gel and mix until well combined.
  • Dip balloons into gelatin liquid making sure they’re coated evenly leaving the bit where the balloon meets the stick free of gelatin. You may want to coat these twice. Let the gelatin set on the first coat for 5 min, and then coat again. If the gelatin stiffens you can melt again in the microwave for 10 seconds.
  • Place the coated balloons standing upright in a cup or in a styrofoam block and allow to dry completely- about 24 hours.
  • To remove balloon, cut away from the stick and pull the balloon out from the bubble. You’ll need to cut away the bottom of the bubbles so they sit evenly on top of the cupcake. You can do this using a pair of scissors.


  • Preheat a fan-forced oven to 160C (320F) or 180C (356F) for a conventional oven. Line a cupcake tin with cupcake liners.
  • 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.
  • Next, add milk, eggs, yogurt, oil and vanilla extract in a large jug and whisk well.
  • Add wet ingredients to dry ingredients in a slow and steady stream until no dry ingredients are visible. Scrape down the bowl, add bubble-gum or strawberry flavouring and pink food dye and mix for another 20 seconds. You will need to scrape down the bowl again and mix until the batter is evenly coloured.
  • 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).
  • Bake for 20-25 min or until a toothpick inserted comes out clean. Allow them to cool completely on a wire cooling rack before frosting.
  • To prepare bubble-gum goo, add white choc and cream to a microwave safe bowl and microwave for 20 seconds at a time, mixing each time until smooth. Add blue food gel and flavouring and mix until well combined.
  • To finish off cupcakes, core the centre of each one and fill with bubble-gum goo. Fit the end of a piping bag with a round tip and frost your cupcakes in a flat swirl as demonstrated in the video. Coat the frosting in pink sprinkles, starting with the top of the frosting and then work your way around the sides of the frosting.
  • Finish off by gently placing your gelatin bubble in the frosting.


Cupcakes can be stored in an airtight container for up to three days.
Bubble-gum flavouring: Can be purchased from your local cake supply store or on Amazon.com
