    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!

Recipe's preparation

    Cake
  1. 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 and boiling water in Thermomix bowl for 3 minutes, 60c Speed 2.
    Increase to speed 3 for 3 minutes.







    Except for the EGGS, add remaining ingredients mix 1 minute on speed 5.
    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 a few hours. When the cake has cooled to room temperature, remove it from the pan.
    It is best to freeze this cake over night and remove from freezer a few hours in advance befor icing the cake.

  2. Caramel Filling
  3. 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.
    Tip into a container and allow to cool in the fridge.
    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.
  4. Chocolate Ganache
  5. 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.

    Tip into a container and allow to cool in the fridge.
  6. Buttercream Icing
  7. Alternative for choc ganache.

    Place All ingredients into bowl and mix for 1 minute on speed 4.

    Scrpe down the sides of the bowl.

    Insert butterfly and whisk for 1 minute on speed 3 until light creamy and smooth.

    For making chocolate buttercream replace 50 grams of icing sugar with 50 grams of cocoa.
  8. Decorate
  9. Top with extra mars bars thinly chopped and sprinkled on top.
    Let your creativity run wild adding various chocolates and macarons.

    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.

    Submitted by SueinIsa on 11. April 2016 - 16:40.

    When you complete step 2 (the first lot in for 6 mins) should the mixture be smooth?  Mine still had big lumps of mars bar in it.  Not sure if that was the way it was supposed to be?  Thanks  tmrc_emoticons.)

  • Hi. Maybe your cake tin

    Submitted by NicoleCarey on 6. November 2015 - 22:11.

    Hi. Maybe your cake tin wasn't big enough as it rises quite significantly. Plain cake flour can be found in the baking aisle of either coles or Woolworths. It's by a brand called lighthouse with blue packaging.

  • I don't know what happened -

    Submitted by Sonster on 6. November 2015 - 21:45.

    I don't know what happened - it was a complete disaster! The cake mixture spilled over the top of the baking mixture and ran to be bottom of my oven! I followed directions carefully. Maybe it was the 'plain cake flour' which I researched to mean 1 part corn flour to 3 parts plain flour. Any ideas?

    Thanks. I think my scales must have been out! This is a superb cake. I made a number of large cakes and cut into smaller ones for a wedding cakes on a tiered stand. These were covered in fondant. It looked and tasted awesome. Thanks so much for a great cake. I've also made it with only one Mars Bar (where did those other ones go?? tmrc_emoticons.D) and it was still fantastic.

    Submitted by NicoleCarey on 7. August 2015 - 18:37.

    That's not good to hear. Maybe your I've runs a bit hotter than notmal? You can always place an extra piec of baking paper over the tin to keep it from burning. Or Heath the choc components for a bit longer at the start.

    Submitted by Ashleighbridget on 4. August 2015 - 07:12.

    I made this for my brothers birthday (at his mud cake request) 

    1. It's a HUGE CAKE and you seriously do need to have the baking paper high above the dish. haha

    2. My father thinks it's the best cake he's ever had. (Albeit maybe the most unhealthiest) 

     

    So thanks!

    Hi there. I measure one teaspoon of vinegar into the 1 cup measuring cup then top it up with milk. It has never weighed that much for me before. As long as you follow the above it should be all good.

    The measurement for buttermilk says 150g, while the information about making it with milk and vinegar weighs out at 220g. Which is it?

    Yes the caramel is for between the layers. If u have any leftover you could also put it on top if you like tmrc_emoticons.)

    yes that's right about the buttercream. It is just an alternative to the choc ganache

    Submitted by Flipper on 1. November 2014 - 17:59.

    Just a quick assembly question - I'm assuming I the caramel filling goes ibetween the layers and then I cover the whole cake with ganache? And the buttercream is unnecessary if I make the ganache?
