Place cereal in a baggie and use a rolling pin to crush it.
In a medium bowl, add peanut butter, butter, and powdered sugar.
Add the crushed cereal to the top of the ingredients.
Mix ingredients until completely combined. It should form a dough-like ball.
Roll into small balls. Place in fridge for at least 2 hours.
Melt chocolate chips in the microwave ⅔ cup at a time. Add a splash of corn oil to melted chocolate, if needed, to thin it out.
Roll balls in melted chocolate and place on parchment paper.
Add the sprinkles while the chocolate is still wet, optional.
They are ready to eat when chocolate is set. You can pop them in the fridge to help speed up this process if you'd like.
