Thermomix Muesli Bars

Image of thermomix crunchy Muesli bar recipe

This Thermomix muesli bar (or Granola bar) recipe is super quick and easy.  I used to make something similar for my son years ago.  So if you’re a mum and you’re trying to satisfy, “Mum I’m hungry” snacks or lunch box treats, save this one, it’s a keeper.

If you bake them off for the time I’ve stated in my recipe you’ll achieve a crunchy bar if you want them a little softer and chewier just bake for a shorter time.  We love crunchy here, but for little ones, you might want soft and chewy.

Classes if you are local (Melbourne) or Zooms from anywhere 🙂

You can change the fruit or nuts to whatever you like, just keep the weights the same for each.  And you can stick them in the freezer in individual portions and dole them out each day for school.  Yay!

Every time I have my grandson over I find myself in the kitchen, baking something. I’m not sure why that is anymore, he’s starting to lose the “less cook somfin Nan” feeling.  Maybe it’s a nurturing mothering sort of thing, or maybe it’s just habit.  Oh, and I do love to see his face when he’s sampling.

The Tin I used is called a USA Biscotti Tin.  They’re brilliant for all sorts of slices.  Right shape and size and non-stick.

  • Thermomix


  • 80 g butter
  • 50 g brown sugar
  • 45 g honey
  • 1 tsp Vanilla
  • 160 g oats not quick oats
  • 60 g dates chopped fine. Or other fruit of your choice great way to use up leftovers
  • 20 g desiccated coconut
  • 60 g nuts I used chopped almonds in this one but anything you like or a mix
  • 40 g pepitas
  • 1 pinch of cinnamon
  • 1 pinch of Allspice or mixed spice
  • 1 pinch salt


  • Line a tin 14cm (w) x 30cm (l) x 5.5cm (h) with baking paper leaving a little extra on two sides, so they're easy to remove later.
  • Preheat your oven to 180°c
  • Weigh the sugar, butter, honey and vanilla into the TM bowl and set to 50°c/5 mins/ speed 3.
  • Weigh the remainder of the ingredients into the TM bowl and set to reverse speed +3/ 10 seconds (if you have a TM 5 you can be doing this in a bowl on top of your TM while the last step is happening. Yes you can weigh while it’s working but not if it’s rocking around. ?
  • Pour the mixture out of the jug into the prepared tin and gently press down to flatten them.
  • Pop them in the oven and bake for 20 minutes then cover with a baking paper lined foil hat like this and bake for a further 15 minutes.
  • Remove from the oven and let rest for 10 minutes, then using a knife mark the top into 10 – 12 portions while still warm. Allow to cool completely in the tin and when cold, remove and finish the cutting.


Make sure you don’t press down too hard, or they’ll be heavy and too hard to cut at the end although you need to get them pressed enough, so they don’t fall apart when cool.  If you bake this recipe off as stated these muesli bars will come out crunchy, but if you want them a little softer just don’t bake them as long.

    This is my favorite muesli bar recipe. I make it for lunchboxes, swap out nuts for sunflower seeds and add cereal like rice bubbles or cornflakes to add more crunch! My kids prefer crunchy baked goods. Delicious with yoghurt too if it’s particularly crumbly.

  2. Love the mixture. I added more nuts and fruit. I think this might have been the reason why my bars didn’t stick together very well. Should I have added more butter or honey?

    1. Hi Penny, Yes for sure. I always say “Make the recipe as intended the first time around, then you know what you have”. It depends on what you’re after; if you want more nuts and fruit, then yes, add more things that help them stick together, but if you wish to have more muesli bars, then I would add 50% to all the recipe ingredients. I hope that makes sense. Thnx for trying them.

    Really enjoyed this! I added 80gm dark choc as well. I put the choc, nuts and dates in and chopped them all first (being lazy), then put aside in a seperate bowl. Without washing the bowl, I then went straight to the step with the butter etc. These are absolutely delicious! My husband loves to take them for brekkie (he wakes at 3am and doesn’t like making brekkie in the house as it used to wake the kids). Such a hit with everyone. Thank you x

    1. Oh, that’s so cool! I absolutely love the dark chocolate addition and the whole idea of being lazy. That’s totally me, the lazy chef, that won’t ever compromise on taste! 🤣🤣🤣
