In a large mixing bowl, combine crushed crunchy peanut butter candy bars, creamy peanut butter, powdered sugar, and vanilla extract. Mix until smooth and slightly sticky.

Roll about 1 tablespoon of the mixture into a ball and place on a parchment-lined baking sheet. Repeat until all are formed.

Refrigerate the balls for at least 30 minutes to firm them up.

Melt milk chocolate chips in a microwave-safe bowl in 30-second intervals until fully smooth.

Dip each chilled ball in the melted chocolate and place back on the baking sheet. Repeat for all.

Before the chocolate sets, add any optional decorations like sprinkles or crushed candy.

Let the chocolate harden at room temperature for about 15-20 minutes before storing.
