Our Thermomix Mars Bar Brownies recipe is simple to make, and even easier to eat!!

Mars Bar Slice, Mars Bar Muffins, Mars Bar Cheesecake – I really don’t think I’ve ever come across a Mars Bar recipe that I didn’t love!!  It’s easy to see why our Thermomix Mars Bar recipes are so popular though, this rich, caramel filled chocolate bar can only make ANY recipe taste better right?!

This Thermomix Mars Bar Brownies recipe is based on my favourite simple Brownie recipe with the delicious addition of FIVE Mars Bars.  It’s a super easy recipe to prepare, however it’s REALLY important that you let these Mars Bar Brownies cool completely in the cake tin before removing/slicing into pieces as the cooling time will help the fudgey brownie centre to set.

You can serve these Mars Bar Brownies at just about any occasion (and they are also an amazing dessert when heated slightly and served with ice cream or our Chocolate Fudge Sauce), however they also make a really lovely (and very much appreciated!!) homemade gift – simply pop a few pieces of brownie into a cello bag and decorate with a ribbon.

Enjoy!
