In a medium sized bowl, whisk together the flour, salt, cinnamon, and baking soda. Set this aside for now.
In the bowl of a stand mixer fitted with the paddle attachment, beat the butter and sugars together on medium speed until light and fluffy (1-2 minutes).
Add the cookie butter, egg, and vanilla and continue beating until the mixture is smooth and creamy.
Then, reduce the mixer to low speed and add the flour mixture, beating until the flour is just incorporated. Make sure not to overmix the dough.
Turn the mixer off and use a cake spatula to fold the chocolate chips and crushed cookies in until they are evenly distributed.
Transfer the dough into a medium bowl, cover with plastic wrap, and place it into the fridge and chill for at least half an hour or overnight.
When you’re ready to bake the cookies, preheat your oven to 350°F and line two cookie sheets with parchment paper. Scoop 1.5 tbsp size balls of the dough and place onto the cookie sheets at least 2 inches apart so they have room to spread.
Bake for 11-13 minutes, or until the cookies start to turn golden brown along the edges. Remove them from the oven and let them rest for 5 minutes on the baking sheet before transferring to a wire rack to cool completely.
