thermomix double chocolate surprise brownies 1

I have to warn you, these brownies are sooo good but sadly sooo bad for your waistline.  If you are on a diet, look away now.

Miss H is having a new school friend over for a play date tomorrow and she is so excited she’s been counting down the sleeps all week.  I promised I’d make her something yummy today for their afternoon tea.

“What you would like me to make?” I asked her.  “Nothing yucky! and not those ‘good for you raison and nut things’.  I hate them!”  She means my muesli bars, which I think I actually very yummy.  “Ok, how about something chocolate?” I asked, “YES!!”  she said, with a huge grin on her face.

I decide to go with a full fat, full chocolate, full of naughty brownie because I’m the best mum ever!!! That will surely earn me at least two love hearts (hand drawn of course).   thermomix double chocolate surprise brownies 1

I’ve added some smarties to these brownies to make them fun,  but you could always substitute with nuts if you wanted to be slightly more healthy (walnuts would be great).

Here is the thermomix recipe for these super delicious, best ever chocolate brownies.

  1. can’t believe i have stumbled across another British mum of 3 living in australia with a thermomix. Going to make your brownies at the wend and your chic chip cookies now before school is out and chaos resumes.
    Looking fwd to following your blog

    • Hi Sophie, Thanks so much for visiting. I so know all about the 3pm chaos, lol. Where about in Aus do you live and where in the UK are you from?? Sorry, I’m so nosey, haha xx

  2. I’m 15 and it’s amazingly fun and easy for me to make for my older brother and his girlfriend and when my mum and sister sister visit us they love them x

  3. I am not really wanting to go out and buy smarties but have an absolute truckload of easter eggs, would you suggest just substituting the smarties with 200g of additional milk choc?

  4. 🙁 100 degrees for 4 mins burnt my chocolate, butter and sugar mixture. Maybe it should be 60 degrees for 4 minutes?
