Preheat oven to 350 degrees F. Line a baking sheet with aluminum foil or parchment paper and set aside.
In your stand mixer*, cream the butter, sugar, egg and vanilla extract until well blended.
Add the dry ingredients: ground cinnamon, baking soda, flour, and salt; mix just until blended (take care not to overmix).
Gently fold in the green chiles and chocolate chips/chunks.
Use an ice cream scoop or a large cereal spoon to drop by rounded spoonfuls on a foil or parchment lined cookie sheet.
Bake at 350 degrees F for 12-13 minutes. For soft, chewy cookies, pull from the oven just as the edges start to brown. The cookies will continue to cool slightly on the baking tray.
Cookies will keep for up to one week in a sealed container at room temperature.
