Add molasses and mix on low speed until combined. Add flour, baking soda, cinnamon, ginger and salt, mixing on low speed just until combined.
TAKE 2 TABLESPOONS of dough and roll into a ball. Place 3 tablespoons sugar on a flat plate and roll dough ball into the sugar. Place ball on prepared baking sheet and continue with remaining dough. Cover both baking sheets and refrigerate for 1 hour before baking.
PREHEAT OVEN to 350F. Remove baking sheets from refrigerator and using the bottom of a glass, flatten each dough ball slightly. Bake cookies 8–10 minutes, until golden around the edges. Let cookies cool completely before filling.

TO ASSEMBLE cookie sandwiches, using a small spoon, place filling in the center of a cookie bottom. Gently press another cookie bottom on top until filling spreads.
