What You Need
Jelly Slice is made using just 7 ingredients...
Note: Scroll to the recipe card at the bottom for the ingredients quantities and full detailed method.
A classic jelly slice is made with 3 layers:
The Base
- Butter - you can use either salted or unsalted butter in this recipe. I generally use unsalted butter, but the choice is yours.
- Crushed biscuits - also known as cookies in the US. Use any plain, sweet biscuits (such as Arnott's Marie biscuits).
The Creamy Filling
- Sweetened condensed milk - I recommend using full fat sweetened condensed milk as it sets firmer and has a slightly richer flavour than skim or light sweetened condensed milk.
- Lemon juice - use either freshly squeezed or store-bought lemon juice. Adding lemon juice to sweetened condensed milk helps to thicken the milk without the need for heating and gives a fresh, creamy flavour.
- Dissolved gelatine powder - use powdered gelatine powder dissolved in boiling water. See my tips below for dissolving gelatine powder.
The Jelly Topping
- Jelly crystals & water - you can use any brand or flavour of jelly you like. Aeroplane jelly is a popular brand of jelly crystals in Australia. When mixed with a combination of boiling water and hot water, the crystals dissolve easily. Once chilled in the fridge, the liquid jelly on top of the slice will set firm.
Step By Step Instructions
Aeroplane Jelly Slice requires a little bit of patience for the layers to set, but it only takes 15 minutes of active preparation time!
Note: Scroll to the recipe card at the bottom for the ingredients quantities and full detailed method.
Step 1 - Make The Jelly
In a bowl or jug, prepare the raspberry jelly as per the packet instructions and leave at room temperature to cool slightly while you prepare the base and filling.
Note: Do not place the jelly into the fridge at this stage as it will set.
Step 2 - Mix The Crushed Biscuits & Melted Butter
Use a food processor, a rolling pin or Thermomix to crush the plain sweet biscuits.
Combine the melted butter with the crushed biscuits and press very firmly into an 18cm x 28cm rectangular baking tray lined with greaseproof paper.
Place into the fridge while you prepare the filling.
Step 3 - Prepare The Creamy Filling
In a large bowl, mix the sweetened condensed milk, lemon juice and dissolved gelatine (see tips below for dissolving gelatine) with a whisk until slightly thickened Alternatively you can do this step in a Thermomix.
Pour the mixture over the crushed biscuit layer and place back into the refrigerator to set (approximately 1 hour).
Step 3 - The Jelly Layer
Once the creamy filling has set, very gently pour the cooled jelly over the top.
Carefully place back into the fridge for 5 hours or until set.
Once set, use a flat, sharp knife to carefully cut into pieces.
Storing Instructions:
Jelly Slice is best prepared and eaten within 3 days.
Storing:
Store Jelly Slice in an airtight container in the fridge for up to 3 days (although I can guarantee it will most likely disappear well before then!)
Freezing:
Jelly Slice is not suitable for freezing.
Expert Tips & FAQ
All your Jelly Slice recipe questions answered....
Sprinkle the gelatine powder over a small bowl or ramekin filled with ⅓ cup of boiling water. Quickly use a fork to whisk the gelatine until fully dissolved.
Absolutely! I have included both Conventional and Thermomix instructions for making Jelly Slice in the Recipe Card below.
No. The gelatine powder is required in the filling to ensure the sweetened condensed milk sets. The filling will remain soft and creamy (not rubbery), but will be firm enough to slice into pieces. There is also gelatine powder in packets of jelly crystals as this is needed for the jelly to set when chilled.
It's important to chill the filling layer for 1 hour (or until set) and then the entire slice (including the jelly layer) for 5 hours. In total, jelly slice requires 6 hours chilling time.

Hi Lucy, my best friend and I made these together, and it turned out amazing ! We actually let the gladwrap rest on top of the jelly while it set in the fridge, which gave it a cool ripple look on top. It was so cool and yummy. Thanks for the awesome recipe !
Lucy
What a great idea! So glad you liked it!
Celeste
Was so easy to make and tasted yummo
Lucy
Thank you so much!
Michael Miller
Can you still make it without lemon juice
Lucy
Hi Michael, you 'could' as the gelatine will thicken the sweetened condensed mill layer but the lemon juice helps to thicken and stabilise it even more.

Hi Lucy
My husband is allergic to citrus - what could we use to replace the lemon juice? Apple cider vinegar? White wine vinegar? Something else? Thanks!
Lucy
Oooh good question!! Hmm yes possibly apple cider vinegar or white vinegar.
