Flapjacks are a super easy treat to make and enjoy and this chocolate flapjack recipe needs only a few simple ingredients and the right technique to guarantee you flapjacks that don’t crumble and fall apart.
Place the butter, sugar and golden syrup in a pan and melt together over a low heat until the sugar has dissolved completely.
Pour in the oats and mix them together well. Ensure all the oats are covered in the butter mixture.
Line and grease a 20x25cm baking tin with parchment paper. Leave the paper to hang over the top of the tin to create an easy way to lift the flapjacks from the tin later.
Tip the mixture into the lined tin and, using the back of a spoon or a spatula, press it down firmly and evenly.
Bake in the oven for 30 minutes.
Remove the tin from the oven, the mixture will still appear slightly soft.
Leave the mixture in the tin to cool and harden.
Once the flapjacks have cooled to at least room temperature, melt the chocolate over a low heat or in 10 second increments in the microwave.
Pour the chocolate over the top in an even layer and allow to set almost completely.
When the chocolate has hardened but isn't completely set, use the parchment paper to lift the mixture out of the tin and place it on a chopping board.
Using a very sharp knife, slice the flapjacks to the desired size. These can be bite-size pieces, square bars, or thin slices. Whatever you prefer.

Recipe Notes
Using porridge oats gives the best results. However, you can also use rolled oats. Jumbo oats create a more crumbly texture and will fall apart more easily.
Take your time to press the mixture down firmly in the tin, this will help to keep it all together.
Don't add extra baking time when you see that the mixture is still soft. It will harden as it cools.
Slicing the flapjacks before the chocolate sets completely will help to give you uniform slices and prevent the chocolate layer from cracking and breaking.
