In a large bowl, blend 4 cups of rice cereal, 1 cup of peanut butter, 1/2 cup of powdered sugar, 1 teaspoon of vanilla extract, and 1/2 teaspoon of salt until thoroughly combined.
Take a quarter sized portion of the mixture and roll them into bite-sized balls, placing them on a parchment-lined tray.
Allow the peanut butter rice crispy balls to chill in the refrigerator for about 30 minutes, helping them firm up.
Place 8 ounces of dark chocolate chips in a microwave-safe bowl. Microwave in 30-second intervals, stirring between each, until the chocolate is completely melted and smooth.
Dip the chilled peanut butter rice crispy balls into the melted dark chocolate, ensuring an even coating. Place them back on the parchment-lined tray.
Allow the dark chocolate coating to set. Expedite the process by placing the tray back in the refrigerator for approximately 15-20 minutes.
Once the chocolate has set, your Peanut Butter Rice Crispy Balls, adorned with a dark chocolate twist, are ready to be savored. Share them during the holidays for a delightful treat that's both easy and indulgent.
