What you do:
1. For the pecan crumble, place crumble ingredients in a food processor. Alternate pulsing and blending the mixture, stopping to scrape down the sides of the mixing bowl as needed, until a graham cracker crust consistency is achieved. Set aside.
2. For the caramel sauce, place ingredients into a blender and blend until fully emulsified. Set aside.
3. For the ice cream, place ingredients into a blender and blend until a thick, smooth ice cream consistency is achieved.
4. Spoon pecan crumble into the bottom of four serving dishes of your choice. Top with ice cream, caramel sauce, and any remaining pecans.
