Preheat the oven to 180℃ / 350℉.
Measure out your butter, golden syrup and light brown sugar in a bowl.
4 tbsp golden syrup, 100 g light brown sugar, 125 g butter
Melt it on high in the microwave for 2 minutes, stirring well after each minute.
Measure out your oats in another bowl, then pour the butter/sugar mixture in and stir well to combine the ingredients fully.
250 g rolled oats
Leave the mixture to cool for 5-10 minutes before adding two thirds of the chocolate chips.
100 g milk chocolate chips
Line your baking pan with baking parchment (if needed). Tip the mixture into the pan and use a wooden spoon to press it firmly down. Scatter the remaining chocolate chips over the top.
Put your pan in the oven and bake for 20 minutes or until the top of the flapjacks are golden. Remove the flapjack tray from the oven, leave to cool for a few minutes, then score the flapjacks into 9 pieces (or as many as you would like to make) while still warm. Leave to cool completely. As they cool they will harden and you can then cut them fully through using the scored lines.Serve with a cup of tea or coffee and enjoy a break.
