Preheat the oven to 180°C. Mix the flour, oats, dates and coconut in a bowl.
Melt the butter in a small saucepan, add the syrup and sugar and heat.
When the butter is bubbling, add the bicarbonate of soda, stir through and remove from the heat.
Pour the butter mixture into the dry ingredients and mix. Using the back of a metal spoon, press the mixture into a greased or lined baking tray (approximately 30cm x 20cm, depending on how thick you like your crunchies). Bake for 15 minutes, then reduce the heat to 160°C and bake for a further 10 minutes, or until golden brown, making sure they don’t burn. Allow to cool in the pan before slicing.
Notes
Store in an airtight container for up to 3 - 4 weeks. You can freeze crunchies too.
