Pre-heat the oven to 160C (350F) fan-forced and line two baking sheets with baking paper.

In a medium bowl, mix together the peanut butter and egg.

In another bowl, combine the sugars, coconut flour, cinnamon, baking powder and chocolate.

Stirring with a wooden spoon, add the dry ingredients to the wet and mix until it forms a dough.

Roll 1 tablespoon of dough at a time into balls and place on the trays leaving 3cm (2") between each one.

Use a fork to press the dough down and then press the other way to make a crossed pattern.

Bake the biscuits for 9-11 minutes or until firm on the outside.

Remove the tray from the oven and leave to rest for 5 minutes then use a spatula to transfer the biscuits to a wire rack to cool completely.
