When I think about my favourite birthday party treats growing up, Jelly Slice is ALWAYS high up on the list and I promise you this is the BEST Jelly Slice Recipe you will ever make! After all what is there not to love about it when you’ve got a yummy buttery base, tangy cheesecake filling and then the sweet jelly topping – yum!
I’ve made a few versions of Jelly Slice in the past including this Strawberry Jelly Slice and my Christmas Jelly Slice, but I have to admit this traditional Jelly Slice recipe is my favourite. I can remember being a little nervous the first time I attempted it as the thought of creating three perfect layers was a little intimidating. However I PROMISE you that this is really easy to achieve and not only does it look great, but it tastes amazing as well.
The secret to achieving perfect layers with your Jelly Slice, is to make sure you let the cheesecake layer cool in the fridge and begin to set before pouring the COOLED jelly over the top. If you try and pour jelly which is still a little warm over the cheesecake layer which hasn’t chilled for long enough you are going to end up with ‘holes’ filled with jelly in your slice – this doesn’t change the taste but can be an issue when you try to cut it into neat little squares.
While I’m all for sticking with the classics, you REALLY need to also try this Christmas Jelly Slice recipe (Thermomix instructions also included) – how fun does it look?!
The Best Jelly Slice Recipe – Thermomix Instructions
- Line the base and the sides of a slice tin with baking paper, making sure you leave plenty hanging over the sides.
- Place the biscuits in the bowl and crush for 5 seconds on speed 9.
- Add the butter and heat for 3 minutes on 80 degrees speed 2.
- Remove biscuit mixture from the bowl and pour into the lined tray. Push the mixture down with a metal spoon to create a flat surface. Place in the fridge for 30 minutes to set.
- To make the filling, combine the gelatine in a jug with the boiling water and allow to cool slightly. In a clean bowl, add the lemon juice and condensed milk and mix for 45 seconds on speed 4. After 5 seconds, remove the measuring cup and carefully pour the gelatine mixture in. Remove the set slice base from the fridge and pour over the filling.
- Put back into the fridge for 30 minutes.
- In a clean Thermomix bowl, add the hot water and heat for 3 minutes on 90 degrees speed 2.
- Add the jelly crystals and one extra teaspoon of gelatine and stir until they have dissolved. Pour jelly into another bowl and allow it to cool until it has reached room temperature.
- Remove the slice from the fridge and carefully pour the jelly over the slice and place it back in the fridge to set for approximately 4 hours – overnight is best.
- Remove the set slice from the fridge and cut into squares.
