Place cooled brown butter (ok if it's still warm) into a stand mixer or large mixing bowl. Add coconut oil, brown sugar, molasses and egg, beating on medium until well combined. Slowly add flour, baking soda, salt, cinnamon and ginger. Mix until just combined. Dough will be thick. Roll heaping tablespoons of dough into granulated sugar and place onto prepared baking sheet. Place 1 inch apart to allow for spreading. Bake for 10-12 minutes, until baked through. Remove and let cool on baking sheet for at least 15 minutes before transferring to cooling rack. Serve room temperature or chilled.
