In a sauce pan, bring the heavy cream to a simmer over medium heat.
Stir in the white chocolate chips, then remove from heat. Stir the mixture until smooth, then let stand for 5 minutes.
Add the butter and vanilla and mix until smooth.
Pour the mixture into a shallow bowl. Cover and refrigerate for at least 4 hours or until it is mostly set up and solid.
Once the truffle mixture is set, use a small cookie scoop to scoop balls of the mixture. Place the balls in a shallow bowl of shredded coconut, and use your fingers to toss and form into a ball.
Place the truffles on a baking sheet and put it in the fridge to set up for 1-2 hours.
Store in the fridge until ready to serve.
Notes
Store leftovers in an airtight container in the fridge for 2 weeks, or in the freezer for 6 months.
You can use toasted, non toasted, sweetened, or unsweetened coconut.
