Step 1: In a large mixing bowl, beat the softened cream cheese, softened butter, and creamy peanut butter together until the mixture is completely smooth and well combined, about 2-3 minutes with an electric mixer.
Step 2: Gradually add the powdered sugar, mixing on low speed until fully incorporated. Once incorporated, increase the speed to medium-high and beat for another 1-2 minutes until the mixture is light and fluffy.
Step 3: Stir in 1 cup of the chopped Reese's Peanut Butter Cups and 1/4 cup of the mini chocolate chips into the cream cheese mixture by hand. Fold them in gently to distribute evenly.
Step 4: Scrape the mixture onto a large piece of plastic wrap. Gather the plastic wrap around the mixture and form it into a firm, round ball shape.
Step 5: Place the wrapped Reese Peanut Butter No Bake Dessert Cheese Ball in the refrigerator for at least 2-4 hours, or preferably overnight, to allow it to firm up properly.
Step 6: Just before serving, unwrap the chilled dessert cheese ball. In a shallow dish or plate, combine the remaining 1/2 cup chopped Reese's Peanut Butter Cups and 1/4 cup mini chocolate chips.
Step 7: Roll the dessert cheese ball in this topping mixture, pressing gently to ensure it is evenly coated on all sides. Transfer to a serving platter.
Step 8: Arrange your favorite dippers around the Reese Peanut Butter No Bake Dessert Cheese Ball and serve immediately. Enjoy!
