Peel your persimmons and add them to a mixing bowl.
Using your hand blender, mix up the persimmons to get a nice pulp. This should be one cup of pulp which is usually around 4 persimmons.
Add in baking soda and mix again.
Next add softened butter, sugar, egg, and vanilla and mix until creamy. Then add in your spices (cinnamon, ground ginger, ground clove, and ground nutmeg) and mix in.
In a separate bowl add in flour and mix in your baking powder.

Once the batter is complete, take an ice cream scoop and scoop your dough onto a cookie sheet covered in parchment paper.
