- For extra flavor, add a pinch of salt to the melted chocolate mixture if using unsalted butter.
- Try substituting creamy peanut butter with almond or sunflower seed butter for a different twist.
- Use dark or milk chocolate chips depending on your sweetness preference.

FAQs
Can I use crunchy peanut butter instead of creamy?
Yes, crunchy peanut butter can be used, but it may affect the texture slightly by adding little peanut pieces to the bars.
What if I don’t have a microwave?
You can melt the chocolate, peanut butter, and butter together in a heatproof bowl set over simmering water (double boiler method), stirring until smooth. Then proceed with the marshmallows and remaining steps.

Ingredients
Main Ingredients
- 7 cups Rice Chex cereal (start with 5 cups and adjust for consistency)
- 1 cup semi-sweet chocolate chips
- 1 cup (258 g) creamy peanut butter
- ¼ cup (½ stick / 57 g) unsalted butter (can use salted)
- 1 bag (10 ounces) mini marshmallows
- ¼ cup (31 g) confectioners’ sugar
Instructions
- Prepare Cereal: Place the Rice Chex cereal in a large mixing bowl and set it aside while preparing the marshmallow mixture.
- Melt Chocolate Mixture: In a medium microwave-safe bowl, combine chocolate chips, peanut butter, and butter. Microwave in 30-second intervals, stirring thoroughly between each until the mixture is fully melted and smooth.
- Add Marshmallows: Stir in the mini marshmallows to the melted mixture. Return to the microwave and heat again in 30-second intervals, stirring until the marshmallows puff up and begin to melt, resulting in a thick and creamy mixture.
- Combine with Cereal: Pour the marshmallow-chocolate mixture over the Rice Chex cereal. Stir well to coat all of the cereal pieces evenly and thoroughly.
- Press Into Pan: Transfer the coated cereal mixture into a greased 9×13 inch baking pan. Press the mixture firmly and evenly into the pan to form a compact layer.
- Chill Bars: Place the pan in the refrigerator and chill for 10-15 minutes to allow the bars to firm up.
- Add Finishing Touch: Lightly dust the top of the chilled bars with confectioners’ sugar, then cut into squares and serve.
Notes
- Start with 5 cups of Rice Chex and add more as needed to achieve the desired consistency when mixing.
- You can use salted butter if unsalted is not available; it will add a slight saltiness to the bars.
- Microwave times may vary; stir frequently to avoid burning the chocolate or marshmallows.
- Store bars in an airtight container in the refrigerator to keep them fresh and firm.
- For a nut-free version, substitute peanut butter with sunflower seed butter and use allergy-friendly chocolate chips.
