Preheat your oven to 180 degrees Celsius (360 F)
Place all ingredients excluding the chocolate into a food processor. You can also use a vented blender (ie a blender that's not a bullet-style blender)
Whizz until smooth
Add the chocolate and pulse a few times so that it is evenly dispersed
Pour into a lined loaf tin or small cake pan
Bake at 180 degrees celsius for 30-40mins depending on tin size. When it is ready it will start to become golden particularly around the edges and the edges will begin to pull away from the tin
Leave to cool in the tin for at least 10 minutes before turning out on a rack to finish cooling.
