Preheat oven to 350 degrees and line two cookie sheets with parchment paper
Using a medium microwave safe bowl, melt the butter
Mix in the pumpkin puree, both sugars, molasses and vanilla extract into the melted butter until combined
In another bowl, whisk together the flour, pumpkin pie spice, baking soda, and salt
Gradually mix in your dry ingredients into the wet until combined
Mix in the chocolate chips and chocolate chunks
Using a medium cookie scoop, scoop some dough onto your hands and roll into a ball
Place onto the cookie sheet and lightly press down with your fingers until a thick disk forms
Repeat steps with remaining dough until all is gone
Place into the oven and bake for 13-15 minutes or until center doesn't look gooey
Allow cookies to cool completely before enjoying!
