Christmas jelly slice recipe

Christmas jelly slice recipe


  • 1 packet sweet plain biscuits (I used Arnotts Nice)
  • 175g unsalted butter
  • 400g sweet condensed milk
  • 1 tablespoon + 1 teaspoon gelatine
  • 1 packet of raspberry jelly


1. Butter a slice tray (16cm x 26cm x 3cm). Dissolve jelly in 1 and 1/2 cups boiling water, place in fridge for about 45 minutes until cool.

2. Crush biscuits in a food processor (or in a plastic bag with a rolling pin), transfer to a bowl and mix in melted butter. Place mixture in prepared tray and press down firmly. Refrigerate for 30 minutes.

3. Dissolve gelatine in 1/2 cup hot water. Combine gelatine mixture with condensed milk in a bowl, pour over biscuit base and place back in fridge for 30 minutes until cool and nearly set.

4. Pour cold jelly on top of slice and return to fridge to set.

5. Slice into squares using a butter knife. I wiped the knife occasionally so that the white filling didn't ruin the look of the jelly.


  • Don't forget the jelly in the fridge! I made two batches - one red and one green, but took my kids to the park, forgot about the green jelly and had to make another jelly.
  • For my third batch of jelly, I coloured a raspberry jelly to purple (my son's favourite colour) using blue food colouring. I think the colouring did something to the jelly because it didn't set as well and kept sliding off the slice. So don't forget the jelly in the fridge.
