Difficulty Easy
Container 1.4L Container 


  • 200g beetroot, peeled (2 medium)

  • 150g zucchini (1 medium)
  • 2 eggs
  • 1 ¾ cup brown sugar
  • ½ cup coconut oil or butter, melted
  • 2/3 cup cocoa powder
  • Pinch of salt
  • 1 ½ cup spelt flour
  • 1 tsp baking powder
  • 2 avocados
  • 2 tbsp tahini
  • 3 tbsp maple syrup
  • 1/4 cup cocoa powder
  • Optional – grated dark chocolate & flaked sea salt


  1. Preheat the oven to 180C. Grease & line a 23cm square baking tin.

  2. Cut the beetroot into large wedges and the zucchini into large pieces.
  3. Run the blender, lid on, on speed 2 and drop the beetroot and zucchini through the lid hole onto the running blades to finely chop them. You want a coarse puree texture. Use the tamper if required.
  4. Turn the blender off and add in the eggs, sugar, coconut oil, cocoa powder, salt, flour & baking powder. Pulse on speed 3, using the tamper to bring the mix together but do not overwork it.
  5. Spoon into the prepared tin and bake for 30-35 minutes, until the brownie is firm in the middle. Allow to cool completely before removing from the tin.
  6. For the frosting, combine the avocado, maple syrup & cacao in the blender and using the tamper, turn the blender on at speed 2, gradually increasing it to speed 5 to make a thick, smooth frosting. Let this sit in the fridge to firm up while waiting for the brownie to cook & cool completely.
  7. Spread the frosting on the cooled brownie, grate over some dark chocolate and sprinkle with flaked sea salt if desired. Cut the brownies into desired sizes.

Tip: Make your own spelt flour by grinding dried spelt grains in the 0.9L Dry Grains container
