    Our Thermomix Oat & Caramel Slice is always a winner! Filled with ooey-gooey caramel, oats and chocolate... talk about YUM!

    Thermomix Oat & Caramel Slice

    If you've been visiting ThermoBliss for a while now, you'll know that we're two girls who LOVE our slices!!! Whether it's a no-bake slice, a chocolate slice or a traditional favourite.. we're definitely big fans!

    Thermomix Oat & Caramel Slice

    And this Thermomix Oat & Caramel Slice is one of our absolute favourites! It's packed full of caramel and chocolate... and is definitely not a recipe for the faint-hearted! It's packed full of sugary goodness... and just try stopping yourself at one piece!

    Thermomix Oat & Caramel Slice

    Before you get baking, just one little tip! This slice has a layer of gooey caramel in the middle (which is AMAZING!), but this means that you really do need to wait until the slice has completely cooled and set before cutting it. I like to leave it overnight... but give it at least a few hours! I know.. I know... it's so hard to wait... BUT it's totally worth it!

    Enjoy! xx

    • Add the plain flour, oats, bi-carb and salt to the bowl. Mix on Reverse, Speed 3, 10 seconds. Scrape down the sides of the bowl and repeat for a further 10 seconds.
    • Add half of the mixture to the tin and press down firmly. Bake in the oven for 10 minutes. (Set aside the other half of the mixture). 
    • Meanwhile place the caramels, cream and salt into the TM bowl. Melt on 80 degrees, Speed 3, 4 minutes (scrape the sides after 2 minutes).

      I've made this again today using the Werthers Toffees coz I couldn't find the caramels anywhere. This is my favourite slice... didn't change anything else!! It is a little on the expensive side but well worth it..

      I've just made this - it's baking in the oven right now and I just have a couple of comments.
      1) Step 6: I didn't realise that I was to put the remaining 1/2 of the oat mixture aside whilst making the caramel, so I just added those ingredients to the TM bowl and now it's all mixed in together – perhaps this could be a bit clearer?
      2) Step 7: Refers to 'salted caramel' but the ingredients list doesn't mention any extra salt. I already used the pinch of salt listed in step 4 so just added another pinch - is that enough?
      I think it will still turn out ok (you can't really go wrong with caramel in my book) but perhaps those two things could be a bit clearer?

        Hi Heidi, thanks for your feedback! I've added in an extra note to make it clearer about setting aside half of the mixture. And yes, it's a pinch of salt in the crumble mixture and a pinch in the caramel mixture. Hope you loved it!!! xx

          Thanks Lucy! It did taste sensational but it was almost impossible to cut haha. It made for a great laugh though with our guests and I'll definitely be trying it again the 'right' way 🙂
