Grease a 20 x 20cm baking tin and line the base with baking paper.

Preheat the oven to 200C (180C fan).

Put the butter, sugar, golden syrup, black treacle (molasses) and vanilla extract in a large microwave safe bowl.

Microwave for 30 seconds, stir and repeat until the grains of sugar have pretty much dissolved into the syrup.

Add the oats, flour, baking powder and ground ginger and stir to coat evenly.

Tip the oat mixture into the lined tin and press to level off.

Bake the flapjacks in the centre of your preheated oven for 20 mins until golden brown.

Run a cutlery knife and the inside edges of the flapjack, then place the tin on a cooling rack to cool completely.

Once cool, turn out on a board and cut into 9 pieces in a 3 x 3 pattern.
