Instructions:

Combine the peanut butter, softened butter, and vanilla extract in a bowl.
Stir in the Rice Krispies, chopped pecans, and shredded coconut until well mixed.
Chill the mixture in the refrigerator for 30 minutes to firm up.
Shape the mixture into balls and place them back in the refrigerator to cool for at least one hour.
For the Chocolate Coating:

In a double boiler, melt together:
1 bag of chocolate chips
1 piece of sweet chocolate (such as a chocolate bar)
Keep the heat low to ensure the chocolate stays smooth and warm.
Dip each ball into the chocolate mixture using a fork, rolling them around until they are completely covered in chocolate.
Place the coated balls on a sheet of parchment paper and refrigerate until the chocolate is set.
Enjoy your delicious chocolate Rice Krispie balls!
