Notes
✔ Extra gooey? Slightly underbake and let them set as they cool.
✔ Crunchy twist? Add chopped peanuts or pretzels for extra texture.
✔ Drizzle alert! Top with melted peanut butter or chocolate for even more decadence.
✔ Storage: Store in an airtight container at room temperature for up to 5 days or freeze for up to 3 months.
