Line a 18 x 28cm baking tin with baking parchment.
Preheat the oven to 180°C (160°C for fan ovens), Gas Mark 4.
Melt the butter and sugar in a large saucepan over a low heat. Add the condensed milk and golden syrup. Remove from the heat and stir in the oats, dried fruit and half of each of the seeds.
Press the mixture into the prepared tin and lightly press on the rest of the seeds, bake for 25-30 minutes until golden. Allow to cool and then cut into 12 bars. Keep in an airtight container.
