In a high-speed blender, combine the soaked cashews, almond milk, powdered sugar, pistachios, pistachio paste (if using), vanilla extract, and salt. Blend until completely smooth and creamy, scraping down the sides as needed. If too thick, add almond milk one tablespoon at a time until desired consistency.

Transfer the pistachio cream to a bowl, cover, and refrigerate for at least 1 hour to thicken.

Brew a strong cup of coffee or espresso and let it cool to room temperature. If using amaretto, stir it into the cooled coffee.
