Creating Peanut Butter Rice Krispie Treats with Chocolate Swirl is a fun and easy process. Follow these steps to make your own delicious treats:

1. Prepare Your Pan: Line a 9×13 inch baking dish with parchment paper for easy removal later.
2. Melt Butter and Marshmallows: In a large saucepan, melt the butter over low heat. Add the mini marshmallows and stir until completely melted and smooth.
3. Add Peanut Butter: Remove from heat and stir in the peanut butter until fully combined.
4. Mix in Cereal: Gradually add the Rice Krispie cereal and a pinch of salt. Stir until the cereal is evenly coated with the peanut butter mixture.
5. Press into Pan: Transfer the mixture to the prepared baking dish. Use a spatula or your hands (greased with butter) to press it down evenly.
6. Melt Chocolate: In a microwave-safe bowl, melt the semi-sweet chocolate chips in 30-second intervals, stirring between each interval until smooth.
7. Swirl the Chocolate: Drizzle the melted chocolate over the pressed Rice Krispie treats. Use a knife or toothpick to swirl the chocolate into the peanut butter mixture.
8. Chill: Place the baking dish in the refrigerator for about 30 minutes to allow the treats to set.
9. Cut into Squares: Once set, remove the treats from the pan using the parchment paper. Cut into squares or rectangles as desired.

These steps will guide you in creating an incredible batch of treats that everyone will love!
