Preheat oven to 180c or 350f.
Grease and line an 18cm x 18cm or 7inch x 7inch (base measurement) baking tin and set aside.
Combine butter, sugar and golden syrup in a medium heatproof bowl (place a piece of kitchen towel/paper on top but not touching the contents - this will save your microwave from splatters).
70 g light brown sugar, 150 g salted butter, 2 tbsp. golden syrup
Microwave on high for 1 - 1 ½ mins until butter is melted, remove from microwave and mix to melt sugar and combine.
Meanwhile place flour, dates and lemon in a medium bowl, mix to combine.
200 g chopped dates, 200 g self-raising flour - sifted, rind of 1 lemon - finely grated
Add melted butter mixture to dates and flour, and mix well to combine.
Press mixture into prepared tin, smoothing the top - I use a mini silicone spatula for this. Bake for 13 - 15 mins, until top is golden brown.
Allow to cool in tin for 30 mins before cutting into 12 squares.
