Preheat the oven to 170'C / Fan 150'C / Gas Mark 2 and line a 23cm square baking tray with baking paper. Set to one side.
Add the butter, sugar and syrup to a large pan and place on a low heat. Stir until the butter has completely melted – be patient, don’t let it start boiling!
Take off the heat and add the oats to the mix. Stir well until fully combined.
Place half of the oat mixture in the lined baking tray and flatten down.
Pour the mincemeat over the top and carefully spread over the oats until fully covered.
Pour over the rest of the oat mixture, covering the mincemeat, and flatten down.
Bake in the middle of the oven until golden brown, approximately 25-30 mins.
Allow to cool completely then cut into 16 squares. Serve them hot or cold – they go really well with a glass of mulled wine!
