Make the Peanut Butter Mixture

1. Combine the Ingredients: In a large bowl, mix the peanut butter, powdered sugar, graham cracker crumbs, vanilla extract, and salt. Stir until fully combined and smooth.
2. Shape the Balls: Use your hands or a spoon to roll the peanut butter mixture into small balls, about 1 inch in diameter. Place them on a baking sheet lined with parchment paper.

Chill the Peanut Butter Balls

1. Chill for Firmness: Pop the baking sheet with the peanut butter balls into the fridge for about 15 minutes, or until firm.

Coat the Balls in Chocolate

1. Melt the Chocolate: In a heatproof bowl, melt the chocolate and vegetable oil (or shortening) together in the microwave or using a double boiler. Stir until smooth.
2. Dip the Peanut Butter Balls: Using a fork, dip each chilled peanut butter ball into the melted chocolate, making sure to coat it completely. Tap off any excess chocolate.
3. Add Peppermint: Before the chocolate sets, sprinkle crushed peppermint on top or roll the ball in the crushed candy for an extra festive touch.

Let the Chocolate Set

1. Cool the Balls: Place the chocolate-coated peanut butter balls back on the parchment paper and allow the chocolate to set at room temperature or chill in the fridge for faster results.
