Ingredients You’ll Need
Gathering the ingredients for this Muddy Buddy Brownies Recipe is wonderfully straightforward. Each component plays its part in creating that divine balance between a soft, chocolatey base and a crunchy, peanut buttery topping.
- Brownie mix: The star of the show provides a rich, fudgy foundation, and using a box mix keeps the process simple without sacrificing flavor.
- Oil, eggs, and water: According to the brownie mix package instructions, these bind and add moisture for the perfect cake-like texture.
- Creamy peanut butter (1/2 cup): Melting smoothly with chocolate, it offers a creamy, nutty flavor that’s utterly addictive atop the brownies.
- Semi-sweet chocolate chips (1 cup): These melt to silky perfection, blending beautifully with peanut butter for a luscious coating.
- Rice Chex cereal (1 1/2 cups): This adds a crispy, light crunch that contrasts the dense brownie beneath.
- Powdered sugar (1/2 cup): The final dusting of sweetness, it enhances the “muddy buddy” look and adds a delicate, melt-in-your-mouth texture.
How to Make Muddy Buddy Brownies Recipe
Step 1: Bake the Brownies
Start by preheating your oven to 350°F (175°C) and preparing a 9×9-inch pan with nonstick spray or parchment paper. Follow the brownie mix instructions exactly, combining oil, eggs, and water as directed. Pour the batter evenly into your pan and bake until a toothpick inserted near the center comes out mostly clean. This foundational step gives you that moist, fudgy base which will hold up perfectly under the crunchy topping.
Step 2: Make the Peanut Butter Chocolate Coating
While the brownies cool completely, it’s time to craft the delicious muddy buddy topping. Combine the chocolate chips and creamy peanut butter in a microwave-safe bowl. Heat in 30-second bursts, stirring consistently after each session until you achieve a smooth, glossy mixture. This combination is where the magic happens, melding nutty richness with sweet chocolate for an irresistible coating.
Step 3: Coat the Cereal
Add the Rice Chex cereal to a large mixing bowl, then pour that melted, luscious peanut butter chocolate mixture over the top. Gently stir to evenly coat every piece of cereal without breaking them up. Next, sprinkle in the powdered sugar and toss gently again, creating the iconic “muddy buddy” look and texture that’s part of what makes these brownies so fun.
Step 4: Assemble and Chill
Once your brownies have cooled completely, spread the cereal mixture evenly over the surface. Pat it down gently so it sticks well to the brownies underneath. Finally, pop the tray into the refrigerator for at least 30 minutes to allow the topping to set nicely, making slicing a breeze and serving an absolute delight.
How to Serve Muddy Buddy Brownies Recipe

Garnishes
For added flair and flavor, consider sprinkling a few chopped peanuts or mini chocolate chips over the top right before chilling. A light drizzle of melted white chocolate can create beautiful contrast and an extra sweet touch that’s bound to impress guests.
Side Dishes
Serve these brownies alongside a scoop of vanilla ice cream or a dollop of whipped cream for a classic indulgence. Fresh berries like strawberries or raspberries bring a bright, tart balance that pairs surprisingly well with the richness of the Muddy Buddy Brownies Recipe.
Creative Ways to Present
For parties or potlucks, place the brownies on a decorative platter lined with parchment paper and sprinkle a few extra Rice Chex around the edges. Alternatively, cut them into bite-sized squares and skewer with a toothpick for easy grab-and-go treats that look adorable and invite indulgence.
Make Ahead and Storage
Storing Leftovers
Keep any leftover Muddy Buddy Brownies in an airtight container at room temperature or in the refrigerator. They will stay fresh and delicious for up to four days, and the topping maintains a satisfying crunch throughout this time.
Freezing
You can freeze these brownies by wrapping them tightly in plastic wrap and placing them in an airtight container or freezer bag. When you’re ready, let them thaw in the fridge overnight to preserve both texture and flavor seamlessly.
Reheating
If you prefer your brownies slightly warm, gently heat a piece in the microwave for about 10 seconds. However, avoid over-heating because the cereal topping can soften or lose its delightful crunchiness.
