Preheat the oven to 350F. Place your cookies in a food processor or blender and grind them until they are fine crumbs. Alternatively, you can put your cookies in a gallon-size plastic bag and crush the cookies with a rolling pin until fine.
Next, make your brown butter. First, cut the butter in small pieces and heat the butter in a small pan on medium heat for about 3-5 minutes until the butter turns an amber color. The butter will first foam and start to pop. Then, brown bits will begin to form in the bottom of the pan. Once browned and popping slows, it is ready. You should smell a nutty aroma. Scrap the butter (and all the of those magical brown bits into a heat-safe bowl and let rest for about 5-10 minutes.
Next, place your cookie crumbs in a medium bowl. Add your sugar, spices, and brown butter. Mix until well combined.
Pour your cookie mixture evenly into a 9-inch or 10-inch springform pan. Press the crumbs down along the bottom and sides of the pan to form the crust. Be sure to pat the crumbs evenly. Alternatively, you can use the back of a measuring cup or spoon to pat the crumbs and form the crust.
Bake the crust for 10 minutes. Once done, remove from oven and set aside. Then, reduce the oven to 325F.
