Place the Powdered Confectioners Sugar (1/2 cup), Ricotta Cheese (1 tub), and Instant Espresso Powder (2 teaspoon) in a food processor or blender. Blend for 1 minute.
Scrape down the sides, add the Vanilla Extract (1 teaspoon), and blend one more minute. The consistency will be thick and creamy, like a mousse.
Fill 8 disposable shot glasses with the ricotta mixture to the top or fill 16 shot glasses half way. Cover and refrigerate 1-hour or overnight.
For the shot glasses filled to the rim, garnish with Chocolate (to taste) or Candy Cane (to taste). Serve chilled. For the shot glasses filled half way, top with Whipped Cream (to taste), then garnish as desired.
Top with a splash of Rum (to taste) for an adult version.
