Combine the tahini, pumpkin puree and butter in a medium bowl of a mixer and beat until blended.
Add the sugar and brown sugar and beat on high until well blended.
Add the eggs and mix on medium until the mixture is smooth.
Add the salt, baking soda, cinnamon and flour and mix on low until well blended.
Add the chocolate chips and mix to combine.
Heat oven to 375F. Line two cookie sheets with parchment paper.
Using a 1 oz. scoop, scoop the dough onto the lined baking sheets leaving about an inch around each cookie so that they brown evenly.
Top each cookie with a few granules of sea salt and bake 15-17 minutes or until golden brown.
Warm, the melted chocolate chips will dominate the cookies, but as they cool the cinnamon will come through. I love them both ways.
Makes about 30 cookies.
