Place the rolled oats, desiccated coconut, raspberries, pitted Medjool dates, vanilla paste or extract, chia seeds, salt, and optional acai powder into a food processor.
Process the mixture until the ingredients break down and begin to stick together.
Stop the food processor once or twice as needed and scrape down the sides of the bowl with a spatula.
Continue processing until the mixture forms a sticky, rollable consistency.
Check the texture by pressing a small amount of the mixture between your fingers. It should hold together firmly.
If the mixture is too wet, add a small amount of additional rolled oats or desiccated coconut and process again.
If the mixture is too dry, add an extra raspberry, a soft pitted date, or a very small splash of water and process until combined.
Scoop portions of the mixture and roll them firmly between your hands to form balls.
Repeat until all of the mixture has been used. The recipe should yield approximately 20 balls, depending on size.
If desired, roll each ball in extra desiccated coconut or cacao powder.
Alternatively, drizzle the balls with melted dark chocolate.
Place the finished bliss balls in an airtight container.
Chill until ready to serve.
