Chocolate Peanut Butter Fudge Crunch
2 sticks (8 ounces) plus 1 Tablespoon unsalted butter
1 jar (16 ounces) creamy peanut butter

Remove from heat; stir in 1 cup peanut butter, then 2 cups rice cereal. Spread mixture evenly in the prepared pan; refrigerate until set, about 15 minutes. Wash out the saucepan.
In the saucepan, combine the remaining 2 sticks butter and the salt; melt over medium heat, stirring. Remove from heat and stir in remaining peanut butter and the confectioners' sugar. Spread half of the peanut butter mixture over the cereal layer. Top with remaining 1 cup cereal.
In a small bowl, microwave the remaining chocolate at medium power until melted, 1½ minutes. Stir into remaining peanut butter mixture. Spread evenly on the cereal-topped peanut butter layer. Refrigerate until set, about 45 minutes.
