Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.

In a medium bowl, whisk together flour, ginger, cinnamon, baking soda, and salt.

In a large bowl, beat softened butter, brown sugar, and granulated sugar until fluffy. Mix in the egg and vanilla extract.

Gradually add the dry ingredients to the wet mixture until just combined.

Scoop dough into balls, roll in granulated sugar, and place on prepared sheets.

Bake for 10–12 minutes until set but soft in the center. Cool on racks for about 5 minutes.

For the filling, beat cream cheese and powdered sugar until smooth. Spread between cooled cookies to assemble.
