I'm cooking this todayRecipe's preparation
- Preheat oven to 150c (fan forced).
Boil your kettle.
Bottom element only if possible. Turn heat down a little if you have to have both elements on.
Grease and line 2 8inch round tins. Make sure the tins don't leak as the mix is very runny.
Ensure baking paper around the sides of the tin are taller than the tin as it will rise significantly.
Crack eggs into a jug and set aside.
Place chocolate broken into pieces. Blitz on speed for 5 seconds. Place mars bars chopped up into three pieces, butter cubed, coffee, sugar, vanilla, cocoa and boiling water in Thermomix bowl for 3 minutes, 60c Speed 2. Increase to speed 3 for another 3 minutes.
Except for the EGGS, add remaining ingredients mix 1 minute on speed 5. Scrape down sides of bowl.
Reduce the blades to speed 3, add the eggs one at a time.
Mix for 1 min on speed 4.
Scrape sides down. Mix again for 30 seconds, speed 4.
Pour mixture into prepared pan.
Place on the middle shelf of the oven.
Bake for anywhere from 1 hour and 10 minutes to 1 hour 30 minutes.
Insert a thin-bladed knife or metal skewer into the centre of the cake to test whether it is cooked through.
When cooked through, remove cake from oven, and allow to cool in the pan for an hour. Move to fridge to cool overnight. Remove from tin the next day.
It is best to freeze this cake over night and remove from freezer a few hours in advance befor icing the cake. - Break white chocolate into pieces into the bowl.
Blitz on Speed 9, 10 seconds.
Add cream and caramel top'n'fill.
Mix for 6 minutes, 60 degrees, speed 2 or until well combined.

Let set as it will be too runny otherwise when stacking the cakes. Run a ring of buttercream around the cake and set in fridge for ten minutes before spreading out caramel. - Break chocolate into pieces into the bowl.
Blitz on Speed 9, 10 seconds.
Add thickened cream and mix for 4 minutes, 60 degrees on speed 2 or until well combined.

Recipe is created forTM 5
If you are using a Thermomix® TM6 measuring cup with your Thermomix® TM5:
For cooking (simmering) at temperatures of 95°C or above (200°F), the simmering basket should always be used instead of the TM6 measuring cup, as the TM6 measuring cup fits tightly in the lid. The simmering basket rests loosely on top, is steam-permeable, and also prevents food spatter from the mixing bowl.Please note that the TM5 mixing bowl has a larger capacity than the TM31 (capacity of 2.2 liters instead of 2.0 liters for TM 31). Recipes for the Thermomix TM5 may not be cooked with a Thermomix TM31 for safety reasons without adjusting the quantities. Risk of scalding by spraying of hot liquids: Do not exceed the maximum filling quantity and observe the filling level markings of the mixing bowl!

Milk choc ok as a substitute for the dark cooking choc in the cake?
I’ve made this recipe quite a few times now and love it! I just use normal plain flour and it comes out fabulous. Yum!
Made this for my chocoholic mars bar loving husband and he LOVED it. Makes a good size cake. Will definitely use again.
Made for my daughters birthday cake and yummy and moist easy to work with.
AWESOME we will make again!
We only halved the recipe and worked wonders for the amount of people we had.
THANKS FOR SHARING!
Thankyou for sharing this recipe. This cake is delicious....a favourite Birthday cake in our house! The recipe makes a very big cake so make sure you put baking paper higher than cake tin as it rises heaps.
I have a 20cm x 30cm tin. Is this tin going to be a good size for this cake? Wondering if I should make double..
That's ok. Oh no sorry to hear that. Im not much of a baker but haven't had that happen with this one before. I'll have a search and see what may help x
Thanks Nic. I think it has melted but the cake has sunk considerably in the middle. was wondering if it was anything to do with the unmelted mars bar pieces. but probably not. Thanks for replying.
Hi sueinlsa. Sometimes the mars bar doesn't melt completely so you can pop the machine on for a little loger for that step. If not it will melt when baking xx Nic.
