Ingredients
Instructions

- Return to the oven and bake for 3 minutes longer.

Tips & Substitutions
For best results, slightly underbake the brownies to maintain a fudgy texture. If you prefer a different flavor, consider using white chocolate chips or almond butter instead of peanut butter. You can also substitute the Rice Krispies with another crunchy cereal for a unique twist. Make sure to stir the chocolate mixture continuously to prevent burning.
Serving Suggestions
These Marshmallow Krispie Bars are delightful on their own but can be paired with a scoop of vanilla ice cream for an extra treat. They also make a great addition to a dessert spread alongside other sweet treats like Finger Cheesewiches or Scrumptious Ice Cream Torte. Serve them at parties or family gatherings for a fun and nostalgic dessert experience.
Storage & Reheating
Store any leftover bars in an airtight container at room temperature for up to three days. If you want to keep them longer, refrigerate for up to a week. To enjoy them warm, simply microwave a bar for a few seconds until the chocolate softens and the marshmallows are gooey again.
