Step 1: In a large mixing bowl, combine the melted butter and vanilla extract. Add the peanut butter and stir until well mixed and smooth.
Step 2: Gradually add the powdered sugar, mixing thoroughly until a smooth, thick dough forms. You may need to use your hands to fully incorporate the sugar.
Step 3: Roll the mixture into small, bite-sized balls (about 1 inch in diameter) and place them onto a parchment-lined baking sheet.
Step 4: Freeze the peanut butter balls for at least 30 minutes to firm up. This step is crucial for easy dipping.
Step 5: While the balls are chilling, prepare your dipping chocolate. Melt your choice of chocolate in a microwave-safe bowl in 30-second intervals, stirring after each, until completely smooth, or use a double boiler method.
Step 6: Dip each frozen peanut butter ball into the melted chocolate, coating it completely. Use a fork or toothpick to lift the ball out, letting any excess chocolate drip off. Place the chocolate-covered balls back on the parchment-lined baking sheet.
Step 7: Allow the chocolate to set at room temperature or in the refrigerator until firm. Enjoy!
