Kirsty is a much lovedThermoFun Club member and she wanted to share with us a living reminder of her inspirational Nana. Introducing, Nana's converted Thermomix Hedgehog slice.

Thank you Kirsty. :)

"I have very fond memories of being taught to cook some classic recipes while holidaying with my Nana as a child. One of my most popular requests was Hedgehog. As an adult, I became known for 'Nana's Hedgehog', so much so that my mum made 100 pieces to use as my wedding cake! When my beautiful Nana passed away in April, at the incredible age of 97½ I decided I needed to convert her recipe to the Thermomix so I could regularly make this treat, and be reminded of the many, many happy times I spent in her kitchen. I was pleased to find it easier in the Thermomix (which of course means we can make it more often!)

I hope you enjoy this as much as we do in my family and I hope you think of the wonderful cooking influences in your life as you make this recipe.

Kirsty xxx"

For anyone wondering, this can be made gluten free by using gluten free arrowroot biscuits (found in the health food aisle of the supermarket). The only change is to increase the biscuits to 300gm, as they are a bit softer so they don't take up as much of the chocolate sauce as standard biscuits.
My gf 7yo gives it a big tick, and my fussy non-gf 5yo also approves!

  Nice slice but wouldn’t dare make it for anyone who is pregnant or has a low immunity. Raw egg is not good .

  Hi Frances I haven't tried it with this recipe, but I do know that bananas and or apple sauce substitute very well for eggs. If you try it please let us know how it goes. :)
