These are similar. Except instead of fudgey chocolate chip brownies, the melted chocolate, crunchy peanut butter, and Rice Krispies are poured over an irresistable s’mores layer of graham crackers and ooey, gooey, toasted marshmallows.
Peanut Butter Crunch S’mores Bars
7 graham crackers
2 1/2 cups miniature marshmallows
1 package (12 ounces or 2 cups) semi-sweet chocolate chips
2/3 cup light corn syrup
3 tablespoons butter or margarine
1/2 cup crunchy peanut butter
3 cups Rice Krispies cereal
Preheat oven to 375°F. Spray a 13x9x2-inch baking dish with cooking spray. Arrange graham crackers in a single layer in dish, breaking crackers as needed to fit.
Sprinkle marshmallows evenly over crackers. Bake for 7-8 minutes or until marshmallows are puffy. Cool completely.
In a 2-quart microwave-safe bowl (or in a medium saucepan over medium low heat), combine chocolate chips, corn syrup, and butter. Microwave on high about 1 1/2 minutes or until chocolate is melted, stirring every 30 seconds. If melting in a saucepan, stir constantly until melted, then remove from heat.
Stir in peanut butter, then stir in Rice Krispies until combined. Spread evenly over marshmallows.
Cover and refrigerate about 1 hour or until firm. Cut and store in an airtight container in refrigerator.
