What You’ll Need

- 4 ½ cups Rice Krispies Cereal
- 1 cup granulated sugar
- 1 cup light corn syrup (Karo syrup works great)
- 1 ⅓ cup creamy peanut butter (use natural peanut butter for a less sweet option)
- 4 (1.5 ounce) Reese’s Peanut Butter Cups, chopped (freeze them for easier chopping)
- ½ cup milk chocolate chips (semi-sweet or dark chocolate chips can be substituted)
How to Make Reese’s Peanut Butter Cup Rice Krispies
- Prepare the cereal: Place the Rice Krispies cereal in a large mixing bowl and set aside.
- Make the peanut butter mixture: In a medium saucepan, combine the sugar, corn syrup, and peanut butter. Stir over medium heat until the mixture is smooth and fully combined, about 3-4 minutes. Remove from heat.
- Combine with cereal: Pour the warm peanut butter mixture over the cereal in the mixing bowl. Stir thoroughly to coat the cereal evenly. Add the chocolate chips and stir again until they begin to melt slightly.
- Add Reese’s chunks: Let the mixture cool for about 1 minute, then gently fold in the chopped Reese’s Peanut Butter Cups. They will soften slightly but should retain some texture.
- Shape the treats: Line a baking sheet with parchment paper. Drop rounded tablespoons of the mixture onto the sheet, spacing them slightly apart.
- Serve or cool: Enjoy them warm and gooey, or let them cool for a firmer texture. Store in an airtight container for up to 3 days.
Storage and Reheating Tips
Store your Reese’s Peanut Butter Cup Rice Krispies in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the fridge for up to a week. If you prefer them warm and gooey, pop them in the microwave for 10-15 seconds before serving. Pro tip: Layer parchment paper between the treats to prevent sticking!
Recipe Variations to Try
Switch things up by using dark chocolate chips instead of milk chocolate for a richer flavor. You can also swap Reese’s chunks for mini peanut butter cups or even crushed pretzels for a salty-sweet twist. For a nut-free version, try sunflower seed butter and dairy-free chocolate chips. Get creative and make it your own!
Time-Saving Hacks
To speed up prep, use pre-chopped Reese’s cups or peanut butter baking chips. If you’re short on time, skip the stovetop and melt the peanut butter mixture in the microwave in 30-second intervals, stirring in between. Bonus tip: Use a cookie scoop to portion the mixture quickly and evenly onto the baking sheet.
Serving Suggestions
These treats are perfect as-is, but you can elevate them by drizzling melted chocolate or caramel on top. Serve them alongside a glass of cold milk or a scoop of vanilla ice cream for an indulgent dessert. They also make great party favors or gifts when wrapped in cellophane bags with a ribbon.
