Add the cashews onto a baking sheet and drizzle with maple syrup. Toast for 3 - 5 minutes until the cashews are golden brown.
Transfer the cashews to a food processor and process on high until smooth and creamy. Depending on your food processor, this could take anywhere from 10 - 20 minutes.
Once smooth, add the coconut oil and vanilla extract and process again until combined. The batter should now be almost pourable.
Pulse in the sprinkles.
Transfer your homemade cashew butter into a sealed container. Store in a cool dry place for 2 - 3 weeks.
