Mars Bar slice has always been a family favourite recipe. It’s quick, easy and oh-so-delicious! So really, what’s not to love? Well we’ve updated this classic recipe and made it Thermomix friendly – so now it’s even quicker and easier!!!!

This recipe is great for getting kids involved with helping out in the kitchen. And with the addition of the Thermomix, they can nearly make this recipe all on their own!

Mars Bar slice really does make the perfect lunchbox filler and you can be guaranteed that it will be gobbled up in an instant. Just make sure you grab a few pieces for yourself before it’s all gone!

Oh and a little handy hint… buy an extra Mars Bar just in case! Funnily enough, the pieces seem to magically disappear from the time you cut them up to the time you pop them into the slice mixture. Gee I wonder where they could go? I hope the smear of chocolate around my mouth doesn’t give away my naughty little secret.

So whether you’re looking for a great slice to take to a party, need some lunchbox fillers or are just after some yummy weekend baking, you really can’t go wrong with our Thermomix Mars Bar Slice. Enjoy!
