Serves: 20
For the base:
  • 1 ripe avocado
  • 1 cup sweet potato puree
  • ½ cup unsweetened applesauce
  • ¼ cup date paste
  • 1 tsp pure vanilla extract
  • 2 eggs
  • ½ cup brown rice flour
  • ½ cup cocoa powder
  • ½ tsp sea salt
  • 1 tsp baking soda
  • ½ cup walnuts
  • ½ cup of raisins
For the marshmallow:
  • 1 cup water
  • 3 tbsp gelatin
  • 1 cup honey
  • 1 tsp vanilla
  • ¼ tsp salt
For the frosting:
  • ½ cup coconut cream
  • 4 tbsp date puree
  • 3 tbsp cocoa powder
  • pinch salt
  • ½ a ripe banana
  • 1 tsp vanilla extract
  • 3 drops of almond essence
  • 2 tbsp coconut oil, melted
For the base:
  1. Preheat your oven to 375°F/180°C. Spray a 9” square baking pan with cooking spray and line pan with baking paper, leaving enough extra to extend over the sides.
  2. Boil the sweet potato and cool a little.
  3. In your food processor, combine avocado, sweet potato, applesauce, date paste, vanilla and eggs and process until smooth and creamy.
  4. In a large mixing bowl, mix together the flour, cocoa powder, salt and baking soda.
  5. Add sweet potato mixture and mix until well combined.
  6. Fold in walnuts and raisins and transfer to your prepared pan.
  7. Spread batter evenly and bake for approximately 25 minutes, or until a skewer inserted in the cake comes out almost clean.
  8. Cool brownies in the pan for 15-20 minutes.
For the marshmallow:
  1. In the bowl of a stand mixer, add the gelatin with ½ cup of the water and leave to soften.
  2. Pour the other ½ cup of water in a saucepan along with the honey, vanilla and the salt.
  3. Bring the mixture to a boil. Place a candy thermometer in the saucepan and continue to boil the mixture until it reaches 240°F (the soft ball stage). This will take approx. 7-8 min. Immediately remove the saucepan from the heat.
  4. Turn your stand mixer to low/med. Slowly pour the honey mixture into the bowl combining it with the softened gelatin. Turn the mixer to high and continue beating the mixtures until it becomes thick (about 10 min).
  5. Turn off the mixer and pour the marshmallow onto the base of the slice. Smooth out the top and leave to set.
For the frosting:
  1. Throw everything into the food processor, and process until smooth and creamy.
  2. Spoon out onto the set marshmallow and smooth the top.
  3. Sprinkle over some coconut and place in the fridge to set the frosting.
