Ingredients
- 7 cups Rice Chex cereal (start with 5 cups and check 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

Instructions
- Step 1: In a large mixing bowl, add the Chex cereal 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 between each, until fully melted and smooth.

- Step 4: Pour the marshmallow mixture over the Chex cereal. Stir thoroughly to generously coat all the cereal pieces.
- Step 5: Transfer the coated cereal mixture to a greased 9×13 inch baking pan. Press it firmly and evenly into the pan.
- Step 6: Refrigerate the pan for 10-15 minutes to allow the bars to set.
- Step 7: Lightly dust the top of the bars with confectioners’ sugar before cutting into squares and serving.
Tips & Variations
- Try adding a splash of vanilla extract to the chocolate and peanut butter mixture for extra flavor.
- You can mix a little confectioners’ sugar into the bars before pressing them into the pan for a sweeter texture.
- Make sure to stir the cereal mixture well to coat every piece evenly for the best texture.
- Swap peanut butter for almond butter or sunflower seed butter for a different nutty taste or to accommodate allergies.
Storage
Store the Puppy Chow Bars in an airtight container in the refrigerator for up to one week. For best texture, allow them to come to room temperature for a few minutes before serving. You can also freeze the bars for longer storage—thaw them in the refrigerator before enjoying.

FAQs
Can I use salted butter instead of unsalted?
Yes, salted butter works just fine in this recipe. It will add a slight salty contrast to the sweetness, which many find delicious.
What can I substitute for mini marshmallows?
If you don’t have mini marshmallows, you can use regular-sized marshmallows, but chop them into smaller pieces for even melting and coating.
