Break the chocolate into squares and place in a bowl. Microwave for a minute or two until melted, then set aside to cool a little.
Meanwhile, beat the eggs with the light brown sugar in a large bowl. Add the melted chocolate, Fine Dark Cocoa Powder, ground almonds, Madagascan Vanilla Extract, and Dr. Oetker Bicarbonate of Soda, and mix well.
In a separate bowl, thoroughly mash the avocado flesh, and add it to the chocolate mixture. Mix thoroughly.
Line a cup cake tin with 24 Dr. Oetker fun baking cases. Transfer the brownie mix into the baking cases, and spread it out evenly. Bake for around 20 minutes, until a cocktail stick comes out clean.
