Preheat the oven to 180°C (350°F) (gas 4)
Put the sugar, butter and syrup into a large deep-sided pan and gently heat until the butter has melted and the sugar has dissolved, stirring to combine the ingredients well.
Remove from the heat and let the mixture cool a little.
Meanwhile lightly grease the trays/sheets.
In a separate bowl sift the flour and bicarbonate of soda/baking soda then stir through the oats.
Now add the dried mixture into the pan a couple of spoonfuls at a time stirring to combine.
Shape into 24 balls and place on the trays/sheets spacing well apart. Then flatten the balls a little. Bake in the oven for about 15 minutes until just starting to turn golden. Remove from the oven and leave on the trays/sheets for 5 minutes before transferring to wire racks to cool completely. Store in an airtight container.
