Process the ingredients. Add the dates, cacao butter, and vanilla extract to a food processor bowl fitted with an S blade and process until completely smooth. The dates will turn into a smooth, sticky paste. Add the almond flour and cacao powder to the food processor and process until well combined. The mixture will be sticky but firm enough to roll into balls. Be careful not to add too much almond flour - the truffles should be moist.
Roll the mixture into balls. Using a 1-Tbsp./15 ml cookie scoop or a spoon, scoop out the mixture and roll it into a ball. If the mixture is too sticky, dust some cacao powder on your hands. Place the ball onto a parchment paper-lined baking sheet. Repeat until all the mixture is used up.
Coat the truffles. You can roll the truffles in a little bit of cacao powder or some chopped nuts.
Chill. Transfer the truffles to the freezer to firm up, for about 20 minutes.
Store. Leftover truffles keep well in an airtight container in the refrigerator for up to 1 week. For longer-term storage, freeze the truffles in an airtight container, separating each layer with parchment paper, so the truffles don't stick together, for up to 1 month.
