This shake is great made with pumpkin or apple pie.
Preheat the oven to 350°. Spread the nuts on a rimmed baking sheet. Bake until fragrant and lightly toasted, 5 to 7 minutes. Let cool. Chop enough nuts to measure about 1 tbsp. and set aside for garnish.
In a blender, mix the remaining nuts, the ice cream, large slice of pie, milk, cardamom, and half the pepper until smooth. Divide between 2 glasses. Top with the whipped cream, chopped nuts, and the remaining pepper. Garnish with the mini slices of pie.
