Preheat oven to 180°C and grease or line a rectangular baking tin with parchment paper.

In a large bowl, combine the melted dark chocolate, melted coconut oil and dairy-free milk. Combine and then add the Horlicks Vegan, plain and coconut flour, light brown sugar, cacao powder and ground flaxseed. 

Combine well and then fold 2/3 of the white chocolate and dark chocolate chunks through the mixture.

Pour the mixture into the tin and flatten so it’s smooth. Now scatter the remaining chocolate chunks on top and gently push down.

Bake in the oven for 40-45 minutes or until a toothpick comes out clean. 

Allow to cool before removing from the tin, slicing and devouring!
