This Thermomix Festive Jelly Slice will make the perfect dessert for your Christmas parties this year! It's no-bake and while it's a little time consuming waiting for the jelly to set, it really is so easy to put together.
When putting this Thermomix Jelly Slice together, make sure that you use a DEEP slice tray as you want your tin to be deep enough to fit the two layers of jelly. I’d also recommend putting your slice tray onto a larger oven tray to move it in and out of the fridge, otherwise you may end up with jelly on the floor which is NOT fun - believe me!

If you wanted to make this slice extra festive, you could pipe some cream and sit strawberries on top to make little strawberry Santas - too cute!

Hello, what size tray do I use?
Whitney broadbent says
Is the condensed milk the sweetened kind or do you mean evaporated milk?
Lucy says
Sweetened condensed milk x
Bianca says
I don't have any lemon juice.
Can I leave it out?
Lauren says
You could but it will impact the taste a little
Suzy says
Hi just wondering do you add all the water to the packet of jelly or just the 250ml boiling water? So it only makes up half the normal packets quantity.....
Lauren says
Hi Suzy,
When I made this I made the jelly as per the packet instructions and made the full quantity. I hope that helps 🙂
melissa says
did you mean melted butter? or is there such a thing of milted butter? i have never heard of it thats all, but i am not a renowned cook 🙂 lol
Lauren says
Sorry Melissa, it's melted butter
Rachael Diprose says
Hi, just checking that 225g was the correct amount of butter? I thought it sounded like a lot compared to other biscuit bases and the mixture is rather sloppy.
Lauren says
Hi Rachael, Yep it is 225g of butter. The extra butter makes the base more 'cake' like, you certainly could use less butter, but your base may be a little more crumbly.
