What is Jelly Slice?

Jelly slice is a traditional Australian no bake dessert usually consisting of three layers:

  • 1st Layer:Crushed biscuits blended with butter.
  • 2nd Layer:Milk jelly made with sweetened condensed milk and gelatine.
  • 3rd Layer:Regular jelly – usually bright red raspberry or green lime jelly.

Red or green jelly slice is most popular at Christmas and Easter celebrations, alongside recipes likepavlova roll,choc ripple logandtrifle.

That said, it really can be served for any celebration or get-together. It’s the old school recipe our mums and grandmas used to make (in Laura’s family, her Aunty Glenda is the jelly slice queen!)

While the traditional dessert is made with gelatin, you can make a vegetarian friendly version by using clear agar agar powder for the middle layer, and a colouredagar agar jellyfor the top layer.

What You’ll Need

Jump to Full Recipe Measurements

  • JellyCrystals –For the traditional bright red colour, use raspberry or strawberry jelly crystals. Other popular flavours are port wine, grape or lime. Sub with your favourite colour or flavour to make it your own.
  • Sweetened Condensed Milk–Sub with light condensed milk for a less sweet slice or plant based alternative such as condensed coconut milk to make it vegan (alongside agar agar). You can also use yoghurt for the healthier option.
  • Gelatine Powder / Gelatin– For a vegetarian version, sub withagar agar powder.
  • Lemon Juice– Either fresh or reconstituted lemon juice will be fine.You can also use lime juice in a pinch.
  • Biscuits– We use Arnott’s ‘Nice’ biscuits, but you can sub with arrowroot biscuits for less sweetness. This recipe also works well with Marie biscuits, scotch finger biscuits, digestives or butternut snap cookies. Crush them with a rolling pin, mortar and pestle or use a food processor for even less effort!
  • Butter–Both salted or unsalted work well – we often use salted butter for a little extra zing.

Wandercook’s Tips

  • Water –This recipe intentionally uses less water than usual when making the jelly layers. This helps set the jelly firmer, resulting in a better final structure for cutting. For a thicker jelly layer, double it and do two packets of jelly instead (still with the less water amount).
  • Be Patient– Wait for each layer to fully set before pouring in the next, otherwise they will blend into each other and you won’t end up with those lovely, clearly defined layers. You can try pouring the liquid jelly over the back of a spoon to help disperse it softly over the surface and stop holes forming in the preceding layer.
  • Handle Carefully– It can be easy to spill the white or red layers, so be careful transferring the tray back and forth from the fridge.

Storage and Freezing

Slice once set and store in the fridge in an airtight container.

Jelly slice will last up to 7 days in the fridge, but best eaten sooner rather than layer. Note: The longer you leave it, the more the jelly colour will start to leach into the condensed milk layer over time.

FAQs

Can I make it without the biscuit base?

The biscuit base is what makes the jelly slice easy to pick up and eat. While youcouldmake the slice without the biscuit base, it will be much harder to work with.

If you really don’t want to include the biscuit base, make sure to swap the gelatine for agar agar powder as this will result in much firmer set jelly layers that can set at room temperature, allowing it to be handled more easily.

My layers didn’t set, what went wrong?

Make sure the gelatine powder has completely dissolved in the boiling water before adding any other ingredients. If you don’t, the jelly layers won’t fully set and will blend together.

What size tray works best for jelly slice?

This recipe works perfectly with a24 cm or 9 inch square baking tray. Line it with baking paper first so you can easily remove the slice from the tray once fully set.

If using a larger tray, you could do a double batch of the ingredients.

Serving Ideas & Variations

  • Extra Layer(s)– You can double or triple the jelly layers with different colours and flavours – just make sure to set it fully between each and pour very gently. Why not make it a festive Christmas jelly slice with an extra layer of green jelly?
  • Extra Fun– Mix sprinkles through the white layer for afairy breadversion of jelly slice!
  • Experiment with Flavours– Trycoffee jellyorpandan coconut jellyinstead.
  • Biscuits– Swap the biscuits for chocolate Tim Tams or Anzac biscuits for extra decadence.
  • Flummery – Make a flummery aka jelly whip for the third (or even a fourth) layer to your jelly slice!
