Chocolate-Peanut Butter Crispy Treats

Butter the inside of a 4- to 6-quart slow cooker. In the prepared cooker combine marshmallows, the 6 tablespoons butter, and peanut butter.

Cover and cook on low about 1 1/2 hours or until smooth, stirring every 30 minutes. Add cereal and peanuts, stirring gently to combine.

Using buttered hands or a buttered 1/4-cup cookie scoop, scoop and shape mixture into 36 balls; place on a buttered sheet of foil. Let stand at room temperature until firm and no longer sticky, about 30 minutes.

Stir shortening into melted peanut butter-flavored pieces until smooth.

Drizzle treats with melted peanut butter sauce and melted chocolate. Sprinkle with additional finely chopped peanuts, if desired. Let stand until set.
