Step 1

Line a baking sheet with parchment. Beat the peanut butter, butter and salt in a large bowl with an electric mixer on medium speed until combined. Add the sifted confectioners’ sugar and vanilla; beat on low until incorporated. Increase to medium-high and beat until fluffy and smooth, about 1 minute. Gently stir in the rice cereal with a rubber spatula. Scoop 2-teaspoon-sized mounds (11 to 12 grams each) and roll into balls. Place on the prepared baking sheet and freeze until very firm but not frozen, 20 to 30 minutes.

Step 2

Microwave the chocolate and coconut oil in a medium microwave-safe bowl in 30 second increments, stirring in between, until the mixture is melted and smooth. Let cool slightly for 2 minutes.

Step 3

Stick a toothpick into the top of a ball and dip the ball into the melted chocolate. Coat most of the ball in chocolate, leaving a small uncoated circle on top; let excess chocolate drip off. Return the ball to the baking sheet and remove the toothpick. Repeat with the remaining balls. Smooth out the hole left by the toothpick if desired. Refrigerate until the chocolate has set and the peanut butter ball is very firm, at least 1 hour. Keep refrigerated until ready to serve.
