Place rice cereal in a sealed bag and crush with a rolling pin until fine crumbs are formed.

In a medium microwave-safe bowl, combine chocolate chips, peanut butter, and butter.

Heat in 30-second intervals, stirring between each, until the mixture is completely smooth.

Stir in vanilla extract and salt.

Fold in the crushed cereal crumbs until fully incorporated.

Refrigerate the mixture for 60 minutes until firm enough to handle.

Scoop 1-tablespoon portions and roll into 1-inch balls.

Place powdered sugar in a shallow bowl and roll each ball until heavily coated.

Store in an airtight container in the refrigerator.
