Root Beer Pudding

Directions

1. 1
   In a commercial blender, grind 1/2 cup root beer candies, the milk powder, cornstarch, and salt into a powder.
2. 2
   In a medium saucepan over moderate heat, bring the whole milk and root beer soda to a simmer. Carefully add the hot mixture to the powder in the blender, and with the blender on low, process for 1 minute. Add the butter and egg yolks, then gradually increase the blender speed to high and blend until smooth, about 1 minute.
3. 3
   Carefully pour the hot pudding back into the medium saucepan, place over moderate heat, and cook, whisking vigorously, until it comes to a simmer. Continue cooking, whisking constantly, until the pudding is very thick, about 2 more minutes. Remove from the heat and let cool to room temperature, about 30 minutes. Place plastic wrap directly on the surface of the pudding and refrigerate at least 1 hour. DO AHEAD:

   Spray a heatproof rubber spatula with nonstick vegetable oil spray and have ready. Line a large rimmed baking sheet with a nonstick baking mat or spray with nonstick vegetable oil spray.
5. 5
   In a medium saucepan over high heat, bring the sugar, glucose syrup, and water to a simmer. Cook, swirling the pan occasionally but not stirring, until the mixture turns a medium-dark caramel color, about 5 minutes. Add the butter, cashews, and salt and use the sprayed rubber spatula to stir the mixture until the cashews are completely covered in caramel.
6. 6
   Carefully pour the nougatine onto the prepared baking sheet, and use the rubber spatula to spread it into a thin, even layer. Set aside to cool and harden, about 30 minutes. Once the nougatine is completely cool, use your hands to break it into small pieces then transfer to a Robot Coupe or food processor, and grind into a coarse powder. DO AHEAD:
7. 7
   In the bowl of a stand mixer fitted with the whisk attachment, beat the cream and sugar until medium peaks form.
8. 8
   Place the remaining 1/2 cup root beer candies in a resealable plastic bag and use a meat mallet or rolling pin to crush them into small pieces.
9. 9
   Divide the chilled pudding among 4 chilled glasses. Dollop each pudding with whipped cream and garnish with the crushed cashew nougatine and root beer candy pieces.
