In a large mixing bowl, add your room temperature coconut oil. It should be solid, but not hard. With an electric mixer on medium-high, mix coconut oil until it's smooth and not chunky.
Add your sugar, vanilla extract, salt and water and mix for another 2-3 minutes until combined.
Now with a large spoon, stir in the flour until combined.
The dough shouldn't be soft and soggy but it shouldn't be dry and crumbling either. Aim for the between, if it's too dry add a little more water; if it's too soggy add a little more flour.
Grab a piece of syran wrap or wax paper and sprinkle a little flour so the dough doesn't stick to the wrap/paper. The dough needs to be formed into a log shape about 2 inches in circumference and then wrapped in the wrap or paper. This can be done with your hands.
Wrap tightly and refrigerated for at least 30 minutes.
Preheat the oven to 350° F and line a baking sheet with parchment paper.
When your dough is hard and ready, take out of fridge and unwrap it. With a sharp knife cut into 1/2 inch pieces and place on baking sheet about 1 inch apart.
Bake in the preheated oven for 18-20 or until the edges are little brown. Transfer them to a cooling rack and cool completely before serving.
*Optional: You can drizzle baking chocolate over them and add some sprinkles. They make perfect holiday treats for Valentine's Day, Easter, Christmas, ect.
