Marble cake steam baked in the Thermomix Varoma (yes really!)

The French Thermomix Facebook groups went completely wild for this recipe this weekend and having tried it myself now, I have to say WOW, just WOW!

You have to try it to believe it!

In terms of which mould to use, it seems that pretty much anything goes. Just make sure it fits in your Varoma though.

For gluten-free, replace plain flour by buckwheat

Serves 8

Active time: 10 minutes – Total time: 45 minutes


  • 4 eggs
  • 150g sugar
  • 225g butter, at room temperature
  • 50g milk
  • 225g self-raising flour
  • 2 heaped tbsp cocoa powder
  • a few drops of vanilla essence

Let’s go…

  1. Add all the ingredients in the mixing bowl, except the cocoa powder. Mix for 1 minutes / speed 5.
  2. Divide the batter in 2. Add 2 heaped tbsp cocoa powder to the batter remaining in the mixing bowl. Mix for 20 seconds / speed 3.
  3. Take 2 spoons and use them to dollop the chocolate and vanilla cake mixes into the tin alternately. Use a skewer to swirl the mixture around in the tin a few times to create a marbled effect.
  4. Place the tin in the Varoma (careful to leave enough openings for the steam to rise). Fill the mixing bowl with water. Bake 50 minutes / Varoma / Speed 1.

Delicious. Bon appetit x


  1. Great looking recipe, can’t wait to try. I have subscribed to your emails. Thanks and bonjour, bon appetit!

  2. Mine was a big fail! The water bubbled up into the varoma and ruined the cake. I tried emptying some of the water out but it was too late. Parts of the cake cooked but other parts were completely water logged!

    • Oh no – very sorry to hear this. Some people use a clean cloth to stop water from dripping on the cake. Saying that, I’ve never had any water dripping on mine?!

  3. What tin is used in the varoma of the thermomix for this marbel cake recipe

    • Hello Michelle,
      I have a range of silicone moulds which I use regularly. Pretty much any mould that would fit in your Varoma, will do the trick. Enjoy x

  4. How much water do yo use to cook the cake?
    Also, do you put the lid of the varoma to cook or leave it open?

  5. Hi, thanks for the recipe. What size is the mould you use to fit in the thermomix varaoma/steamer?
