FAQs
Can I use regular-sized marshmallows instead of mini marshmallows?
Yes, you can use regular marshmallows, but chopping them into smaller pieces helps them melt more evenly and blend better with the cereal.
Can these bars be made gluten-free?
Reese’s Puffs cereal is typically gluten-free, but always check the packaging to be sure. Using certified gluten-free cereal and ensuring all other ingredients are free from gluten will make these bars safe for gluten-sensitive individuals.

Ingredients
Main Ingredients
- 4 tablespoons salted butter (add 1/4 teaspoon salt if using unsalted)
- 10.5 oz mini marshmallows (use fresh for best melting)
- Optional: 1/3 cup peanut butter
- 5 cups Reese’s Puffs cereal
Optional Drizzle Toppings
- 1/2 cup chocolate chips
- 1/2 cup peanut butter
Instructions
- Melt Ingredients: In a large saucepan, gently melt the butter over low heat to avoid burning. Once melted, add the mini marshmallows and stir continuously until the mixture becomes completely smooth and uniform. Remove the pan from heat promptly to prevent overcooking.
- Combine with Cereal: Pour the Reese’s Puffs cereal into the marshmallow mixture. Stir thoroughly to coat all the cereal evenly with the marshmallow and butter mixture, ensuring every piece is well covered.
- Press into Pan: Prepare an 8-inch pan by greasing or lining it with parchment paper. Transfer the coated cereal mixture into the pan. Use a buttered spatula or wax paper to press the mixture firmly and evenly into the pan, creating a compact layer. Allow it to cool and set completely for optimal bar shape.
- Cut Bars: Once cooled and set, remove the mixture from the pan and cut it into 8 equal bars for serving.
- Optional Drizzle: For an extra sweet touch, melt the chocolate chips and peanut butter separately either in a microwave or over a double boiler. Drizzle these melted toppings over the bars. Let the drizzle firm up before serving to avoid messiness.
Notes
- Use fresh mini marshmallows for best melting and texture.
- Butter the spatula or wax paper when pressing the mixture to prevent sticking.
- If you prefer a peanut butter flavor, mix the optional 1/3 cup peanut butter in with the melted marshmallows before adding cereal.
- Allow the bars to fully cool and set to ensure they hold their shape when cut and served.
- Store bars in an airtight container at room temperature for up to 3 days for best freshness.
