In a high-powered blender or a food processor (I use my Vitamix), blend the soaked cashews, coconut yogurt, pumpkin, maple syrup, arrowroot starch, pumpkin pie spice, vanilla extract, sea salt, and vanilla bean powder. Scrape down the sides of the container or use the tamper as necessary to get a super smooth consistency. It will take about 3 to 5 minutes of blending to get it super smooth and creamy.
1⅓ cup raw cashews, 1 cup vegan coconut yogurt, ⅓ cup pumpkin purée, ⅓ cup pure maple syrup, 3 tablespoons arrowroot starch, 2 teaspoons pumpkin pie spice, 1 teaspoon vanilla extract, ½ teaspoon sea salt, ¼ teaspoon vanilla bean powder or another teaspoon of vanilla extract
