What Is Jelly Slice?
Jelly slice is a three-layered dessert made with a:
- Biscuit base – usually made from crushed sweet biscuits and butter.
- Creamy filling – typically a mix of sweetened condensed milk and lemon juice set with gelatine.
- Jelly topping – made with flavoured jelly crystals and water, poured over the set creamy layer.
Each layer complements the others, with a firm, crunchy base, a smooth and tangy middle, and a sweet, fruity finish.
Ingredients
For the base:
- 250g plain sweet biscuits (like Marie or Digestive)
- 125g unsalted butter, melted
For the filling:
- 395g can sweetened condensed milk
- ½ cup lemon juice (freshly squeezed)
- 1 tablespoon gelatine powder
- ¼ cup boiling water
For the jelly topping:
- 1 packet (85g) flavoured jelly crystals (strawberry or raspberry works well)
- 1 cup boiling water
- 1 cup cold water
Method
Step 1: Prepare the tin
Line a rectangular or square slice tin (approx. 20x30cm) with baking paper, leaving some overhang on the sides to lift the slice out easily later.
Step 2: Make the base
Crush the biscuits in a food processor or with a rolling pin until they resemble fine crumbs. Combine with melted butter and mix until evenly coated. Press the mixture firmly and evenly into the base of the tin. Place in the fridge for 15–20 minutes to chill and firm up.
Step 3: Prepare the creamy filling
In a small bowl, sprinkle the gelatine over the boiling water and stir until completely dissolved. In a separate bowl, mix the sweetened condensed milk and lemon juice until smooth. Then stir in the dissolved gelatine. Pour this creamy mixture over the chilled biscuit base and return the tin to the fridge. Let it set for at least 1 hour or until firm.
Step 4: Make the jelly layer
Dissolve the jelly crystals in 1 cup of boiling water, stirring until completely dissolved. Add 1 cup of cold water and mix well. Allow the jelly to cool to room temperature but not set before pouring it over the cream layer. This prevents the jelly from melting the middle layer.
Step 5: Set and serve
Carefully pour the cooled jelly over the creamy filling. Place the slice back into the fridge for at least 4 hours or overnight to set completely. Once firm, lift the slice out using the baking paper and cut it into squares or bars using a sharp knife.
Tips for Perfect Jelly Slice
- Cool the jelly completely before pouring it onto the creamy layer, or it may seep into it or cause it to break.
- Use fresh lemon juice for the filling it adds a bright, tangy flavour that balances the sweetness of the condensed milk.
- Chill each layer properly before adding the next to ensure clean, distinct layers.
- Run your knife under hot water before slicing to get neat, clean cuts.
Variations
- Different jelly flavours: Try lime, mango, or blueberry jelly for a fun twist. You can even use two jelly layers for a rainbow effect.
- Add fruit: Place thin slices of strawberries, kiwi, or blueberries on the creamy layer before adding the jelly for a decorative finish.
- Use a cheesecake filling: Swap out the condensed milk filling with a no-bake cream cheese mixture for a richer dessert.
Storage and Shelf Life
Jelly slice should be stored in an airtight container in the fridge. It will keep well for up to 5 days. It’s not suitable for freezing, as the jelly and cream layers may separate or weep upon thawing.
