Place the chopped butter, caster sugar, honey, cinnamon, salt and vanilla extract into the Thermomix bowl. Melt for 4 minutes, 50 degrees, Speed 2 (or until the mixture is melted and smooth). Allow to cool slightly.
Add the egg and the self-raising flour. Mix for 20 seconds, REVERSE, Speed 3 or until combined (you may need to scrape down the sides of the bowl partway through). At this stage the mixture will be warm and sticky. Chill in the fridge for 1 hour or until firm.
Preheat oven to 180 degrees celsius (fan-forced).
Roll the mixture into tablespoon-sized balls. Place onto baking paper lined flat baking trays, leaving a 5cm gap between each dough ball (this will allow the cookies to spread when baked).
Cook for 12 minutes (rotating the trays part-way through) or until lightly golden brown. Cool on trays for 10 minutes before transferring to a wire rack to cool completely.
