In a food processor, combine all of the truffle ingredients. Process until the mixture is smooth and has a sandy consistency.
Use a small cookie dough scoop or a teaspoon to scoop a ball of the mixture and then roll in your hands to form the truffles. Place them on a plate and refrigerate for 2 hours before dipping.In a heat safe bowl, over a pan of simmering water, melt the white chocolate chips and the coconut oil, stirring frequently to prevent the white chocolate from burning.
Dip the refrigerated truffles into the white chocolate and use a fork to roll them around in the bowl, evenly coating the whole truffle.
Place dipped truffles on a baking sheet lined with parchment paper and sprinkle with cardamom.
Refrigerate again for at least 30 minutes and enjoy!
