Key Ingredients
- Corn Chex cereal: The crispy, airy base that gives these bars their essential crunch.
- Semi-sweet chocolate chips: Melted to create the rich coating that holds everything together.
- Creamy peanut butter: Adds nutty flavor and helps the bars set. You can use any nut butter you prefer if you would rather stay away from peanuts.

How to Make Muddy Buddy Bars
- Prep the pan and bowl. Line an 8×8-inch baking pan with parchment paper, leaving an overhang, then add the chocolate chips, peanut butter, and butter to a large microwave-safe bowl.
- Melt in short bursts. Microwave in 30-second increments, stirring after each one.
- Stir until smooth. Keep stirring until the mixture is completely melted and glossy.
- Pour over the cereal. Add the Chex cereal to a large, wide bowl and pour the melted chocolate mixture over the top.
- Fold gently. Fold with a spatula until every piece is evenly coated, being careful not to crush the cereal.
- Press and chill. Press the mixture firmly into the lined pan, then refrigerate for 1 to 2 hours, until the bars are firm and set.
- Slice into squares. Lift the slab out using the parchment overhang and slice it slowly with a serrated knife.
- Toss in powdered sugar. Roll each square in a bowl of powdered sugar until fully coated, then enjoy!
Expert Tips
- Melt the chocolate gently. Use low heat or short microwave bursts so the chocolate, peanut butter, and butter don’t burn or seize.
- Use an extra wide bowl. It makes it easier to coat the cereal evenly without crushing it.
- Press firmly. A flat-bottomed measuring cup helps pack the mixture so the bars hold together when sliced.
- Chill completely. Let the bars fully set in the fridge before slicing. It makes cutting neat squares much easier.
- Shake instead of rolling. For the classic method, add the squares to a zip-top bag of powdered sugar and gently shake to coat.
Muddy Buddy Bars FAQs
Of course! I prefer the corn flavor, but you can use wheat or rice Chex cereal in muddy buddy bars too. Each has a slightly different texture and flavor that’s fun to play around with. If you love cinnamon and chocolate together, cinnamon Chex is a great option.
Absolutely. I used semi-sweet because it has a nice balance of sweetness. Use milk chocolate if you want your muddy buddy bars sweeter, dark chocolate if you want them less sweet, or white chocolate chips for a completely different flavor. The prep and chill time stay the same.
Store muddy buddy bars in an airtight container or zip-top bag. They keep on the counter for 3 to 4 days or in the fridge for up to a week.
Yes. Wrap muddy buddy bars in plastic wrap first, then place them in an airtight container to help prevent freezer burn. Freeze for 1 to 2 months. Depending on how they look after thawing, you can dust them with more powdered sugar.
There are a ton of mix-ins you can add to muddy buddy bars, like mini marshmallows, chopped candy bars such as Butterfinger or Snickers, salted pretzels, or nuts. Holiday M&Ms give them a festive look!

The trick with these for me is being really gentle when mixing the melted chocolate mixture into the Chex. I’ve found that folding instead of stirring keeps the cereal from getting crushed, so you still get those nice crunchy pieces throughout the bars.
