Set your oven to 180°C (160°C fan) / 350°F. Line a baking tray with parchment paper so the biscuits won’t stick.
In a medium bowl, stir together the flour, baking soda, ginger, cinnamon, and pumpkin pie spice. Give it a quick whisk to make sure everything is evenly mixed.
In another bowl, beat the softened butter and sugar until it looks light and smooth. This takes just a couple of minutes by hand.
Pour in the golden syrup and mix until fully combined. It will look sticky and soft—that’s perfect.
Gradually stir the dry mix into the wet mix. You’ll get a soft dough that’s a little sticky but still easy to shape.
Scoop out small balls of dough (about the size of a walnut) and place them on your baking tray with space between them. They’ll spread as they bake.
Pop them in the oven for 10–12 minutes. They’ll puff up at first, then flatten into lovely round biscuits with a slightly cracked top.
Let them rest on the tray for a few minutes before moving them to a wire rack. They’ll firm up as they cool.
