The recipe below is the recipe as it reads in the Thermomix guide, Everyday cooking for every family. I am sure you can find a method for making them without Thermomix.
You can make these for your child if you are comfortable with coconut as an ingredient. It took me a while to try.
What you need:
120 g butter
100 g golden syrup (we use local, dark maple syrup)
1 tsp baking soda
100 g rolled oats
150 g plain flour
75 g sugar (we use Wholesome Sweeteners)
75 g dark brown sugar (we use Wholesome Sweeteners)
50 g desiccated coconut (check package carefully for allergy warning)
Pre-heat oven to 335 F (160 C) (I am still working on the prefect temperature between 335-350 F). Place baking paper on baking tray
Place butter and syrup into TM bowl. Heat for 2 minutes at 60 degrees C on speed 2 until fully dissolved. Place baking soda into TM bowl and mix for 5 seconds on speed 3.
Add remaining ingredients and set dial to closed lid position and mix for 30-35 seconds on Interval speed.
Place one tablespoon of mixture onto baking tray and push down to flatten. Make sure to leave room between each one for spreading.
Bake for 10 minutes or until golden brown. I find that they firm up when cooling.
Remove from oven and allow to cool on tray for 5 minutes, then transfer to wire racks (I just put on plate) to cool completely.
