Preheat the oven to 350°F. Gather all ingredients to ensure a smooth baking process.
Whisk the flour, ginger, cinnamon, and sea salt in a large bowl. Set aside for later use.
Cream the vegan butter and sugar in a medium bowl. Add molasses and applesauce, beating until fully mixed. Combine with dry ingredients to form a dough.
Cover the dough in plastic then chill for 30 minutes to firm up.
Roll out the dough on a floured surface and cut into shapes with cookie cutters.
Place cut cookies on a parchment-lined baking sheet and chill again.
Bake cookies for 12-14 minutes until they are set but still soft.
Cool cookies before decorating with vegan royal icing.
