In a large bowl, mix cream cheese, powdered sugar, peanut butter, and vanilla extract until smooth and well combined.
Fold in crushed graham crackers and mini chocolate chips until the mixture is uniform.
Roll the mixture into small balls, about 1-inch in diameter, and place them on a baking sheet lined with parchment paper.
Freeze the balls for about 30 minutes or until firm.
Dip each chilled ball in melted chocolate, then roll in crushed graham crackers to coat.
Place the coated balls back on the parchment paper and refrigerate until the chocolate sets.
Serve chilled. These no-bake peanut butter cheesecake balls are a decadent treat, combining the flavors of peanut butter and chocolate in a bite-sized dessert that’s perfect for sharing or snacking.
