2 cups all-purpose flour
2 teaspoons baking soda
1 1/2 teaspoons ground cinnamon
1 teaspoon ground ginger
3/4 teaspoons ground cardamom
1/2 teaspoons kosher salt
1 large egg
1/2 cup (1 stick) unsalted butter, melted
1/3 cup granulated sugar
1/3 cup mild-flavored (light) or robust-flavored (dark) molasses
1/4 cup (packed) dark brown sugar
1 teaspoon Vain Indonesian Vanilla extracted in Ginger Spirits
Coarse sanding or raw sugar (for rolling)
Place racks in lower and upper thirds of oven; preheat to 375°F. Whisk flour, baking soda, cinnamon, ginger, cardamom, and salt in a small bowl. Whisk egg, butter, granulated sugar, molasses, vanilla extract and brown sugar in a medium bowl. Mix in dry ingredients just to combine.
Place sanding sugar in a shallow bowl. Scoop out dough by the tablespoonful and roll into balls (if dough is sticky, chill 20 minutes). Roll in sugar and place on 2 parchment-lined baking sheets, spacing 2" apart.
Bake cookies, rotating baking sheets halfway through, until cookies are puffed, cracked, and just set around edges (over-baked cookies won't be chewy), 8–10 minutes. Transfer to wire racks and let cool.
MAKE AHEAD: Cookie dough can be made and rolled into balls 2 weeks ahead. Freeze on a baking sheet; transfer to resealable plastic bags. Let sit at room temperature 30 minutes before rolling in sugar.
