Notes

Use commercial creamy peanut butter rather than natural styles for best results. For variations, try using crunchy peanut butter, almond butter, or add mix-ins like mini chocolate chips, crushed pretzels, or chopped Reese's cups. A sprinkle of flaky salt on top adds a delicious sweet-salty contrast. Store in an airtight container in the refrigerator.
