Reese’s Puffs Cereal Bars Ingredients
For the Base
• Butter – Adds richness and helps bind the mixture; substitute with margarine for a dairy-free option.
• Mini Marshmallows – Provide sweetness and structure; use regular marshmallows if mini are not available, but cut them into smaller pieces for even melting.
• Peanut Butter – Adds creaminess and flavor while contributing protein; for nut allergies, use sunflower seed butter or tahini.
• Reese’s Puffs Cereal – Infuses the bars with that crunchy chocolate peanut butter taste; substitution with other cereals like Cocoa Puffs or Rice Krispies can yield different flavor profiles.
Step‑by‑Step Instructions for No-Bake Reese’s Puffs Cereal Bars
Step 1: Melt the Butter
In a large saucepan over medium-low heat, melt 4 tablespoons of butter. As it begins to bubble, take care not to let it brown, stirring occasionally. Once melted, the butter will create a rich base for your No-Bake Reese’s Puffs Cereal Bars, giving them that deliciously buttery flavor.
Step 2: Add the Marshmallows
Stir in 10 ounces of mini marshmallows into the melted butter. Continue to stir gently for about 2-3 minutes, until the marshmallows are mostly melted and smooth. This step is crucial; the combination of butter and melted marshmallows will create a gooey mixture that binds the bars perfectly.
Step 3: Incorporate the Peanut Butter
Remove the saucepan from heat and mix in ½ cup of peanut butter. Stir vigorously until fully combined, resulting in a creamy, sweet filling. The peanut butter adds a delightful richness that complements the chocolate in the Reese’s Puffs, enhancing the overall flavor of your cereal bars.
Step 4: Combine with Cereal
Next, gently fold in 13 ounces of Reese’s Puffs cereal into the warm marshmallow mixture. Use a spatula to quickly stir and coat each piece of cereal evenly, ensuring every bite is packed with that signature chocolatey peanut butter goodness. The mixture should be sticky but well combined.
Step 5: Press into the Pan
Transfer the sticky mixture into a greased 9×13-inch pan, using a spatula or your buttered hands to press it down firmly. Aim for an even layer that fills the pan to the edges, compacting it to create a solid bar structure. The pressing action is key to ensuring your No-Bake Reese’s Puffs Cereal Bars hold together nicely.
Step 6: Let It Cool
Set the pan aside at room temperature for about 30 minutes to allow the mixture to cool and set. You can also pop it in the refrigerator for 15 minutes if you’d like to speed up this process. This cooling time is essential for the bars to attain their chewy and crunchy texture.
Step 7: Cut and Serve
Once cooled and firm, remove the bars from the pan. Use a sharp knife to cut them into squares or rectangles, as desired. Serve these delightful No-Bake Reese’s Puffs Cereal Bars at parties, in lunch boxes, or as an easy after-school snack that everyone will love!

No-Bake Reese’s Puffs Cereal Bars Recipe FAQs
How do I choose the best peanut butter for this recipe?
Absolutely! For the best flavor, opt for a creamy peanut butter without added sugars or oils. Natural options tend to work best, as they provide a rich taste. If you’re dealing with allergies, sunflower seed butter is a fantastic nut-free alternative that still brings a lovely creaminess.
Can I store the bars at room temperature?
Yes! Keep your No-Bake Reese’s Puffs Cereal Bars tightly covered at room temperature for up to 3-4 days. This will help maintain their chewy texture and delicious flavor. Be sure to choose a cool, dry place in your kitchen, away from direct sunlight to extend their shelf life!
What’s the best way to freeze these cereal bars?
To freeze your cereal bars, wrap each bar tightly in plastic wrap or place them in an airtight container with parchment paper in between to prevent sticking. They can be frozen for up to 2 months. When you’re ready to enjoy one, simply transfer it to the fridge overnight or microwave it for 10-15 seconds for a warm treat.
What do I do if the marshmallows aren’t melting smoothly?
If your marshmallows aren’t melting smoothly, it’s likely that the heat is too high. Be sure to melt the marshmallows over medium-low heat and stir gently. If they are still not melting well, turn the heat down further and allow more time while stirring continuously until smooth. Using mini marshmallows or cutting large ones into smaller pieces can also help them melt evenly.
Are these bars safe for kids with nut allergies?
Definitely! You can easily adapt this recipe by swapping peanut butter for sunflower seed butter or tahini, which makes it nut-free. Just make sure to check all labels for possible cross-contamination if you’re preparing these for schools or playdates.
Can I use a different type of cereal?
Very! While Reese’s Puffs give these bars their signature flavor, feel free to substitute with other cereals like Cocoa Puffs or Rice Krispies. Each option brings its own texture and taste experience, so have fun experimenting!
