Directions: Peanut Butter Cup Rice Krispies Treats

Step 1: Prepare Your Pan
Begin by greasing your baking pan with a bit of butter or lining it with parchment paper. This will ensure your Peanut Butter Cup Rice Krispies Treats come out easily once they’re set.
Step 2: Melt the Butter and Marshmallows
In a large saucepan over medium heat, melt the unsalted butter. As soon as the butter is melted, add in the miniature marshmallows. Stir continuously until the marshmallows are completely melted and smooth.
Step 3: Mix in the Peanut Butter
Remove the saucepan from heat and stir in the creamy peanut butter until well combined. The mixture should be smooth and creamy, with no lumps.
Step 4: Combine with Rice Krispies
In your large mixing bowl, add the Rice Krispies. Pour the melted marshmallow and peanut butter mixture over the Rice Krispies and gently fold until everything is evenly coated.
Step 5: Add the Peanut Butter Cups
Carefully fold in the quartered peanut butter cups, making sure they are evenly distributed throughout the mixture.
Step 6: Press into the Pan
Transfer the mixture into your prepared baking pan. Use your spatula to press it down evenly, ensuring it’s packed tightly for the best texture.
Step 7: Melt the Chocolate
In a double boiler or microwave-safe bowl, melt the milk chocolate chips until smooth. If using a microwave, heat in 30-second intervals, stirring in between to avoid burning.
Step 8: Drizzle the Chocolate
Once the chocolate is melted, drizzle it over the top of the pressed Rice Krispies mixture. Use a spatula or the back of a spoon to spread it evenly if desired.
Step 9: Set and Slice
Allow the treats to cool at room temperature for about 30 minutes until set. Once cooled, slice into squares and enjoy!
