Preheat oven to 180ºC (356ºF). Line a large baking sheet with parchment paper and set aside.
In a large mixing bowl, whisk together the flour and ginger.
Add cubed butter and rub it into the flour using your hands for about 1 minute until it resembles a coarse crumb.
Stir through brown sugar with a wooden spoon.
In a separate small mixing bowl, whisk together the egg and molasses.
Pour the egg and molasses mixture into the flour mixture and stir until a soft dough forms.
To form biscuits, pick up one tablespoon of dough and roll into a smooth ball. Place on lined baking sheet and press it down into a thick disc using the palm of your hand.
Repeat with remaining dough leaving a small gap between each biscuit to allow for spreading, about 5cm (1 inch).
Bake for 12-15 minutes until lightly golden around the edges and biscuits come off easily from the parchment paper.
Remove from oven and cool on baking sheet for 3 minutes.
Transfer to a wire rack to cool completely.
Serve and enjoy!
Notes
Store in an airtight container, at room temperature, for 1 week - 10 days.
To freeze biscuits, allow them to cool down completely, freeze them on a tray individually, and then transfer them to a sealed container or freezer bag with parchment paper layers between them. Label and store for up to 3 months.
To thaw frozen biscuits, either leave them on a plate at room temperature for several hours or thaw them overnight in the fridge while still in their container or bag.
