Marty McFly’s Hoverboard Sour Gummy

*This recipe is by one of our Love Baking Club subscribers, Indya Shaw. Thank you for this recipe, Indya!


  • 21g gelatine powder
  • 2 x 85g packets of raspberry jelly
  • 1 1/4 cup hot water
  • Citric acid & Caster sugar (to coat)
  • Green, pink and yellow fondant
  • A skateboard cookie cutter, OR a curved letter “U” cookie cutter
  • A small circle fondant cutter (optional, but helpful)
  • Paper and pencil (option, but helpful)


  1. Pour gelatine powder and both packets of jelly crystals into a heatproof bowl.
  2. Boil 1 and 1/4 cups of water in a kettle, then add to the bowl of jelly.
  3. Carefully stir the hot water into the jelly until all the crystals have dissolved. Line a deep tray with baking paper and have some hanging over the edges at either end. Pour the liquid into the tray, then place in the refrigerator for at least an hour – I left mine overnight just to be sure.
  4. When your jelly is set, lift it out by grabbing the two overlapping pieces of baking paper. Flip it over onto a clean chopping board, then peel the baking paper off. Now, start cutting out your skateboard pieces with your cookie cutter. Don’t forget to trim one end of your jelly shape with a knife so that it isn’t curved anymore, as that’s how the hoverboard looks!
  5. Pour some citric acid and caster sugar into a bowl; play around with the amounts of both until you get a taste that you like, then pick up your gummy hoverboards and run them through the citric acid sugar mixture until all the sides and edges are covered.
  6. To make the fondant decorations, I traced around the cookie cutter I used multiple times onto some paper, then placed those outlines underneath your baking paper. Roll out some green fondant, then use your circle fondant cutter to cut out a circle, and place it on top of one of your outlines to make sure you’re happy with the size of it in regards to the entire hoverboard.

    You could also just roll some fondant in your hands and flatten it to make this shape, and that way it can be any size you wish! When you’ve found a size you’re happy with, cut out one green circle for each hoverboard you have, but don’t put it on the hoverboard yet.

  7. Roll out your yellow fondant and cut it into strips, then line those strips up with the outlines you drew, and cut the ends down to size so there won’t be any overlap. Remember that these strips sit horizontally on the board, so be sure to measure them while they’re facing the correct way. Cut two of these strips for every hoverboard you have, then put them aside with your green circles.
  8. Roll out your pink fondant and cut it into strips like you did with your yellow fondant, but this time make it slightly thicker. Line it up with your outlines and trim the edges down to size. Make one of these for each hoverboard you have.
  9. Roll out more pink fondant and cut it into thinner strips than the previous two. Get one of your green circles that you have out before, and use that as a guide so you know how short to trim your pink strips, as they will be placed on top to be the “strap”.
  10. Once you have all your fondant pieces cut out, you can start putting them on your jelly! Keep in mind that fondant and liquid are not friends, so these are best eaten soon after being put together, otherwise the fondant starts to dissolve. If you have time to leave the fondant out a bit beforehand so that it hardens before you add it to your gummies, that might help a bit.
