Equipment

  • Thermomix
  • Oven

Ingredients

  • 150 grams butter
  • 220 grams caster sugar
  • 75 grams cocoa
  • 1 teaspoon vanilla extract
  • 3 eggs
  • 75 grams plain flour
  • 5 x 47 gram Mars Bars

Instructions

  • Preheat your oven to 160 degrees celsius (fan-forced) and line the base and sides of a 20cm square baking tin with baking paper – this will help you to remove the Mars Bar Brownies once they are cooked.
  • Roughly chop the Mars Bars and set aside until needed.
  • Place the butter (which has been cut into 4 pieces, cocoa and caster sugar into your Thermomix bowl and cook for 3 minutes, 60 degrees, speed 2 to melt. If it's not quite melted, cook for a further 1 minute, 60 degrees, speed 2.
  • Add the vanilla extract, eggs and plain flour and mix for 10 seconds, speed 4 to combine.
  • Scrape down the sides of your Thermomix bowl and add the Mars Bar pieces (reserving approximately 1 bar) you set aside earlier and mix for 6 seconds, speed 4 on REVERSE to combine.
  • Pour the brownie mixture into the prepared tin and use a spatula to gently spread it across the tin. Gently press the remaining Mars Bar pieces into the top of the brownie. Place the brownies into the oven to bake for 35 minutes.
  • Carefully remove the cooked brownies from the oven and allow them to cool in the tin before removing, cut into small pieces .

Notes

  • You can use 'Fun Size' Mars Bars for this recipe. Please note you will need approximately 250grams.
  • It is 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.
  • To store, place in an airtight container and store in a cool dry place (pantry) for up to three days. These Brownies can also be stored in the fridge, allow the brownies to come to room temperature before serving.
  • To freeze, place in a freezer safe container and freeze for up to one month.
  • 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.
