Equipment

  • Microwave or Thermomix
  • Oven

Ingredients

  • 150 g butter
  • 275 g (1 ¼cups) caster sugar see notes
  • 75 g (¾ cup) cocoa powder
  • 2 tsp vanilla extract or vanilla bean paste
  • 3 eggs room temperature
  • 75 g (½ cup) plain flour
  • 100 g white chocolate chopped into chunks
  • 100 g dark chocolate chopped into chunks

Instructions

  • Preheat oven to 160 degrees Celsius (fan-forced) and line a 20cm square tin with baking paper. Set aside.
  • Place the butter into a microwave-safe bowl. Heat for 1 minute.
    If using a Thermomix: Place the butter into the Thermomix bowl. Melt for 3 minutes on 80 degrees, Speed 2.
  • Add the caster sugar and sifted cocoa powder and stir.
    Heat in the microwave on 30 second bursts (50% power) until sugar dissolved and ingredients combined - stirring each time.
    If using a Thermomix: Add the caster sugar and cocoa powder and mix for 10 seconds on Speed 4. Scrape down the sides of the bowl and repeat for a further 10 seconds.
  • Allow to cool slightly.
  • Add the vanilla extract and the eggs and whisk until combined.
    If using a Thermomix: Add the vanilla extract and the eggs and mix for 10 seconds on Reverse, Speed 4. Scrape down the sides and repeat.
  • Sift the plain flour into the bowl and gently fold through.
    Fold through half of the chopped white and dark chocolate chunks.
    If using a Thermomix: Add the plain flour and mix for 5 seconds on Speed 4. Scrape the sides of the bowl and repeat. Fold through half of the chopped white and dark chocolate chunks with the spatula.
  • Pour the brownie mixture into the prepared tin and sprinkle the remaining white and dark chocolate chunks over the top.
    Bake for 30-35 minutes or until cooked through.
  • Leave in the tin to cool completely.

Notes

RECIPE NOTES & TIPS:
  • Line your tin with baking paper/parchment paper. This will make it easier to remove them from the tin later. Leave the edges over hanging slightly for convenience.
  • Cocoa Powder - whatever type you use, make sure it’s a good quality one! Dutch processed cocoa powder lends a deep smooth flavour and is recommended, but natural cocoa powder works too if that’s what you have on hand.
  • Chocolate - I use blocks of white chocolate and dark chocolate and use a knife to cut them into small chunks. Alternatively, you can use chocolate chips.
  • Sift the plain flour before adding it to the batter.
  • Don’t overmix the batter once the flour has been added. Overbeating will add air, which will produce cakey brownies, rather than fudgy.
  • Don’t overbake! Brownies will continue to cook after they’ve been removed from the oven. So, it’s best to remove them when they are slightly under cooked, rather than over cooked. All ovens differ slightly, so start to check them at the 20-minute mark and then in 5-minute intervals until they are ready. If you want fudgy brownies, remove them from the oven when the sides have begun to shrink away from the tin but the centre is still gooey.
  • For gooey brownies, cook for 30 minutes and test by inserting a toothpick into the centre for a second or two. If the toothpick is covered in thick (but not runny) chocolate mixture, then you will have gooey brownies.
  • For fudgy/moist brownies, cook for 35 minutes and test with a toothpick which should come out with less thick mixture on it. The top should be flaky and set. 
  • Cool before cutting - allow the brownies to cool in the tin before cutting into them. You will have neater slices if they are cut at room temperature.
  • Serve them on their own, dusted with icing sugar or slather ganache or frosting over the top. You can also heat them and add a big scoop of your favourite ice cream!
  • Storage - store brownies in an airtight container at room temperature for up to 4 days, or freeze them for up to 3 months.
  • Freezing - allow the brownies to cool to room temperature first and slice them into individual serves (or leave the slab whole, if preferred). Wrap the brownies in baking paper and store them in an airtight container in the freezer for up to 3 months. To thaw, leave the slices in a container in the fridge overnight, or sit them at room temperature for 1-2 hours. To warm, place them in the microwave until heated through.
