Preheat the oven to 350°F (175°C).
Line two baking sheets with parchment paper.
In a medium bowl, whisk together flour, ginger, cinnamon, cloves, nutmeg, baking soda, and salt. Set aside.
In a large bowl, beat the butter, granulated sugar, and brown sugar until smooth and slightly fluffy, about 2 minutes.
Beat in the egg, then add the molasses and vanilla. Mix until fully combined.
The mixture may look a bit separated—that’s fine.
Add the dry ingredients to the wet ingredients and mix on low just until the flour disappears. Do not overmix.
Fold in the white chocolate chips. If the dough feels sticky, cover and chill for 30–45 minutes to make it easier to handle and to reduce spreading.
Scoop dough into 1.5-tablespoon balls (about a heaping tablespoon).
If you like a crackly sugar crust, roll each ball in granulated sugar.
Arrange on prepared sheets, spacing about 2 inches apart. Bake for 9–11 minutes until the edges are set and the centers look slightly soft and puffy.
Sprinkle each cookie with a tiny pinch of flaky sea salt, if using. Let cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
Enjoy warm for melty chips, or let them cool for a chewier texture.
They’ll firm up as they rest.
