2 tablespoons unsalted butter, at room temperature
How to make it
In a food processor, blend pecans, brown sugar, and cinnamon until nuts are finely chopped. Add butter and process until well combined. Press mixture into bottom and sides of a 9-inch (23cm) tart pan with a removable bottom. Bake for 20 minutes in a 325 degrees F (160 degrees C) oven or until golden brown. Transfer to rack and cool to room temperature.
