In a medium bowl, mix almond butter and maple syrup until well combined.
Add almond flour and matcha powder, then mix until everything is blended.
Use a cookie scoop or tablespoon to form mixture into balls. Place them on a parchment-lined plate and freeze for 10-15 minutes to firm up.
While the truffles chill, melt white chocolate chips in the microwave with 1 teaspoon of coconut oil, if desired. Heat in 30-second intervals, stirring until smooth.
Dip each truffle into the melted white chocolate, then return them to the freezer to set.
Optionally, sprinkle with more matcha powder before freezing.
Once firm, they're ready to enjoy!
