Puppy Chow Bars Recipe
Introduction
Puppy Chow Bars are a delightful twist on the classic snack, combining crunchy cereal with a creamy chocolate and peanut butter coating to create an irresistible treat. Easy to make and perfect for sharing, these bars offer a sweet, marshmallow-packed experience that both kids and adults will love.

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
- Step 1: Place the Rice Chex cereal in a large mixing bowl and set aside.
- Step 2: In a medium microwave-safe bowl, combine the chocolate chips, peanut butter, and butter. Microwave in 30-second intervals, stirring well after each, until completely melted and smooth.
- Step 3: Add the mini marshmallows to the melted mixture. Return to the microwave and heat in 30-second intervals, stirring each time, until the marshmallows puff up and melt into a thick, creamy mixture.
- Step 4: Pour the marshmallow mixture over the Rice Chex cereal. Stir thoroughly to ensure every piece is generously coated.
- Step 5: Transfer the coated cereal mixture into a greased 9×13-inch baking pan. Press the mixture firmly and evenly into the pan.
- Step 6: Refrigerate the pan for 10-15 minutes to allow the bars to set.
- Step 7: Once chilled, lightly dust the top of the bars with confectioners’ sugar. Cut into squares and serve.
Tips & Variations
- For a nut-free version, substitute the peanut butter with sunflower seed butter or omit it entirely and increase the amount of chocolate chips slightly.
- Add Golden Grahams cereal to the mix for a crunchier, s’mores-inspired variation.
- To make cutting easier, lightly grease your knife or use a plastic knife to prevent sticking.
- If you want extra chewiness, slightly undercook the marshmallows when melting to retain some texture.
Storage
Store Puppy Chow Bars in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week. For best texture, bring refrigerated bars to room temperature before serving. They can also be frozen for up to a month; thaw in the refrigerator overnight before enjoying.

FAQs
Can I use a different cereal instead of Rice Chex?
Yes, you can substitute Rice Chex with other similar cereals like Corn Chex or even Golden Grahams for a different flavor and texture, but be sure to adjust marshmallow and coating quantities as needed.
What can I do if the marshmallow mixture is too thick or not melting well?
Microwave the mixture in additional 15- to 30-second intervals, stirring well each time until it reaches a thick but pourable consistency. Avoid overheating, which can cause marshmallows to harden.

Instructions
- Add Chex to bowl: Place the Rice Chex cereal in a large mixing bowl and set aside to prepare for coating.

- Pour marshmallow mixture over cereal: Pour the melted marshmallow chocolate mixture over the Rice Chex cereal. Stir thoroughly and gently to coat all the cereal pieces evenly with the sticky mixture.

Notes
- Start with 5 cups of Rice Chex and add more as needed to achieve the right consistency and thickness of bars.
- If you prefer, salted butter can be used instead of unsalted; reduce added salt in other recipes accordingly.
- Heating the marshmallow mixture in short intervals helps prevent burning and ensures smooth melting.
- Make sure to press the mixture firmly into the pan to help the bars hold together when cut.
- Store bars in an airtight container at room temperature for up to 3 days or refrigerate for longer freshness.
