Ingredients
The foundation of this incredible dessert is a rich, fudgy brownie. Using high-quality ingredients will ensure your brownies are deeply chocolatey and perfectly moist, providing the ideal base for our marshmallow and peanut butter layers. This classic brownie recipe is straightforward and delivers exceptional flavor.
Brownie Ingredients
- 2 sticks unsalted butter
- 2 cups granulated sugar
- 9 tablespoons unsweetened cocoa powder
- 4 large eggs
- 1 1/2 cups all-purpose flour
- 1/2 teaspoon salt
- 1/2 teaspoon baking powder
- 2 1/2 cups mini marshmallows (reserved for filling)
The magic truly happens with these topping ingredients, transforming an already delicious brownie into an extraordinary creation. The combination of creamy peanut butter, melted chocolate, and crunchy Rice Krispies forms an irresistible, textural contrast that’s simply unmatched. Ensure your peanut butter is fresh for the best flavor!
Topping Ingredients
- 1 cup creamy peanut butter
- 1 cup semi-sweet chocolate chips
- 2 cups Rice Krispies cereal
Instructions
For the Brownies
- In a medium saucepan, gently melt the butter over low heat. Once melted, remove from heat and stir in the cocoa powder and granulated sugar until fully combined and smooth. It’s important to let this rich mixture cool slightly (to lukewarm) before adding the eggs to prevent them from scrambling. This also helps create that signature fudgy texture.
- Once the chocolate mixture has cooled to lukewarm, crack in the large eggs one at a time, mixing thoroughly after each addition until a smooth, glossy batter forms. This step ensures proper emulsification, which contributes to a perfectly moist and fudgy brownie texture.
- Gradually add the all-purpose flour, baking powder, and salt to the wet ingredients. Mix just until combined; be careful not to overmix, as this can develop gluten and lead to tough, cakey brownies. Pour the luscious batter evenly into a greased 9×13 inch baking pan. For easy removal and clean slices, you can line the pan with parchment paper, leaving an overhang on the sides.
- Bake in a preheated oven at 350°F (175°C) for 20-25 minutes. A good indicator that your brownies are done is when a toothpick inserted into the center comes out with moist crumbs, not wet batter. Avoid overbaking to maintain that signature fudgy texture that makes these brownies so irresistible.
- Immediately after removing the brownies from the oven, evenly scatter the 2 1/2 cups of mini marshmallows over the hot surface. The residual heat from the freshly baked brownies will begin to melt them, creating that delightful gooey layer.
- Return the pan to the oven for just 2 more minutes, or until the marshmallows are puffed and slightly golden. Keep a close eye on them, as they can brown quickly! Once removed, allow the marshmallow-topped brownies to cool completely on a wire rack. This cooling step is crucial for the marshmallow layer to set properly before adding the final topping, ensuring distinct and beautiful layers.
For the Topping
- In a separate medium saucepan, melt the semi-sweet chocolate chips and creamy peanut butter together over very low heat, stirring constantly until smooth and fully combined. Alternatively, you can melt them in a microwave-safe bowl in 30-second intervals, stirring after each, to prevent burning. Remove from heat as soon as it’s melted to keep the chocolate from scorching or becoming grainy.
- Add the Rice Krispies cereal to the melted chocolate-peanut butter mixture. Gently fold them in until the cereal is fully coated. Be careful not to crush the cereal too much, as you want to preserve its light and crisp texture for that satisfying crunch.
- Once the marshmallow brownie base has completely cooled (this is paramount, as adding the topping to a warm base will cause it to melt and become messy), spread the peanut butter Rice Krispies topping evenly over the marshmallow layer. Use an offset spatula or the back of a spoon to create a smooth, consistent layer.
- Before slicing and serving, allow the chocolate and peanut butter topping to set. You can do this by letting it sit at room temperature for about an hour, or by refrigerating it for 15-30 minutes for a quicker set. Once firm, slice into squares with a sharp knife, wiping the blade between cuts for the cleanest possible edges, and prepare for an unforgettable dessert experience!

Tips for Achieving Brownie Perfection
To ensure your Marshmallow Peanut Butter Rice Krispies Brownies turn out absolutely perfect, here are some expert tips to guide you through the baking process and guarantee exceptional results:
- Use Quality Ingredients: The foundation of any truly great recipe is good ingredients. Opt for high-quality unsalted butter for richness, a rich unsweetened cocoa powder for deep chocolate flavor, and fresh creamy peanut butter for the smoothest topping. These small details can make a significant difference in the final taste and texture of your brownies.
- Don’t Overmix the Brownie Batter: For that signature dense, fudgy texture that everyone loves, it’s crucial to mix the dry ingredients into the wet just until they are barely combined. Overmixing the flour will develop gluten, which can lead to tough, cakey brownies rather than the moist, chewy ones you desire.
- Avoid Overbaking: Brownies can transition from perfectly fudgy to dry and crumbly very quickly. Start checking for doneness at the lower end of the recommended baking time (around 20 minutes). A toothpick inserted into the center should come out with moist crumbs attached, not wet batter. Remember, brownies continue to cook slightly after being removed from the oven.
- Patience with Cooling is Key: This is one of the most important tips! It’s absolutely crucial to allow the brownie base, especially the marshmallow layer, to cool completely before spreading the Rice Krispies topping. If the brownies are still warm, the topping will melt and blend into the marshmallow, ruining the distinct layers and desired textures.
- Grease and Line Your Pan: For effortless removal and beautifully clean slices, thoroughly grease your 9×13 inch baking pan. For extra insurance and easier handling, line it with parchment paper, leaving an overhang on the longer sides. This creates convenient “handles” to lift the cooled brownies cleanly out of the pan.
- Evenly Spread Marshmallows: When adding the mini marshmallows to the hot brownies, try to spread them in a single, even layer over the entire surface. This ensures uniform melting and an even gooey layer across all slices, guaranteeing that every piece gets a perfect marshmallow bite.
- Use Creamy Peanut Butter: For the smoothest and most consistent topping, creamy peanut butter is highly recommended. If you opt for natural peanut butter (the kind that separates oil), ensure it’s very well stirred and emulsified before adding it to the chocolate, or it might result in a slightly oilier or inconsistent topping texture.
Variations & Customizations for Your Marshmallow Peanut Butter Rice Krispies Brownies
While the original recipe for these brownies is divine, feel free to unleash your inner chef and customize them to your liking. Here are some delightful variations and additions you can explore:
- Chocolate Choices: Don’t limit yourself to semi-sweet chocolate chips in the topping. Experiment with different types of chocolate for varied flavor profiles. Milk chocolate chips will offer a sweeter, milder flavor, while dark chocolate chips will provide a more intense, bittersweet contrast that beautifully cuts through the sweetness of the marshmallow and peanut butter. You could even try white chocolate chips for a truly unique twist!
- Nutty Additions: For an extra layer of crunch and enhanced nutty flavor, consider folding in a half cup of chopped nuts into the Rice Krispies topping mixture. Peanuts are a natural fit, but almonds, walnuts, or even pecans would also be delicious, adding another dimension to the textural experience.
- Extract Enhancements: Elevate the flavor of your brownie base by adding a teaspoon of pure vanilla extract to the brownie batter. For those who enjoy something a little different, a touch of almond extract (start with just 1/2 teaspoon, as it’s potent) could also offer a unique and delightful aroma that complements the other flavors.
- A Hint of Spice: For adventurous palates seeking a subtle kick, a tiny pinch of cayenne pepper or chili powder (start with 1/8 teaspoon and adjust to taste) in the brownie batter can add a sophisticated warmth that perfectly complements the chocolate without making the brownies overtly spicy.
- Festive Sprinkles: If you’re making these brownies for a special occasion or holiday, add some colorful sprinkles on top of the still-wet Rice Krispies layer before it sets. This instantly adds a fun, festive touch that kids and adults alike will adore.
- Pretzel Crunch: For a delightful salty-sweet combination, consider crushing some pretzels and folding them into the peanut butter chocolate mixture alongside, or even instead of, the Rice Krispies. The saltiness of the pretzels provides a fantastic counterpoint to the sweet layers.
Serving and Storage Suggestions
To get the most out of your delicious Marshmallow Peanut Butter Rice Krispies Brownies, here are some tips for serving them and keeping them fresh:
Serving Suggestions:
- These brownies are a complete and incredibly satisfying dessert on their own. They are perfect accompanied by a simple glass of cold milk, which truly enhances the nostalgic flavors, or a hot cup of coffee for a more adult indulgence.
- For an extra special and truly decadent treat, serve a slightly warmed brownie square with a generous scoop of premium vanilla bean ice cream. The delightful contrast of the warm, gooey brownie and the cold, creamy ice cream is simply heavenly.
- A light drizzle of warm caramel sauce, a sprinkle of flaky sea salt, or even a dusting of cocoa powder over the top just before serving can elevate the flavors even further, adding a gourmet touch that will impress your guests.
- If preparing for a party or a crowd, cut them into smaller, bite-sized squares. This makes them easy to pick up, minimizes mess, and allows guests to sample more of your delicious offerings.
Storage Instructions:
- Room Temperature: To maintain optimal freshness and texture, store these decadent Marshmallow Peanut Butter Rice Krispies Brownies in an airtight container at room temperature for up to 3-4 days. While they are safe to eat longer, the Rice Krispies topping might start to lose some of its desirable crispness over time.
- Refrigeration: For longer storage, or if you simply prefer a firmer, chewier brownie, they can be refrigerated in an airtight container for up to a week. If refrigerating, allow them to come back to room temperature for about 15-20 minutes before serving to ensure the marshmallow layer softens up and regains its wonderfully gooey texture.
- Freezing: These brownies freeze exceptionally well! To freeze, first allow them to cool completely. Then, wrap individual slices tightly in plastic wrap, ensuring no air exposure, and place them in a freezer-safe bag or container. They can be frozen for up to 2-3 months. When ready to enjoy, simply thaw them at room temperature for a few hours or overnight in the refrigerator.
Frequently Asked Questions About Marshmallow Peanut Butter Rice Krispies Brownies
Have some questions about making these irresistible layered brownies? We’ve got answers to help you bake the perfect batch every time!
Q: Can I use regular marshmallows instead of mini marshmallows?
A: Yes, you can! If you only have regular-sized marshmallows on hand, you’ll need to cut them into smaller pieces (quarters or halves, depending on their size) to ensure they melt evenly and create a smooth, consistent layer over the hot brownie surface. This prevents some parts from being too thick or not melting properly.
Q: What kind of peanut butter works best for the topping?
A: Creamy peanut butter is generally recommended for the topping as it creates a smoother, more uniform texture when melted with the chocolate, which is ideal for spreading. If you use natural peanut butter (the kind that separates oil), make sure it’s very well stirred and emulsified before adding it to the chocolate, or it might result in a slightly oilier or less consistent topping texture.
Q: My Rice Krispies topping isn’t crunchy, what went wrong?
A: The most common reason for a soft or less-crunchy topping is adding it while the brownie base (especially the marshmallow layer) is still warm. It is absolutely crucial for the brownies to be completely cooled and set before spreading the Rice Krispies topping. If the base is warm, the heat will quickly soften the cereal. Also, ensure you don’t overcook the chocolate/peanut butter mixture, as excessive heat can sometimes affect the cereal’s crispness.
Q: Can I make these brownies ahead of time for an event?
A: Absolutely! These Marshmallow Peanut Butter Rice Krispies Brownies are an excellent make-ahead dessert. The flavors often meld and deepen overnight, making them arguably even more delicious the next day. Just store them properly as advised in the storage section to maintain their freshness and delightful textures.
Q: Is there a substitute for Rice Krispies cereal?
A: While Rice Krispies provide a unique light and airy crispness, you could experiment with other puffed cereals (like Chex cereal, lightly crushed) or even crushed pretzels for a salty-sweet crunch. Keep in mind that using alternatives will change the flavor and texture profile slightly, so the original recipe delivers the intended experience.
Q: How do I get clean slices of these layered brownies?
A: The key to achieving beautifully clean slices with distinct layers is ensuring the brownies are completely set and firm. Chilling them in the refrigerator for 15-30 minutes before cutting can help immensely. Use a large, sharp knife, and wipe the blade clean with a warm, damp cloth after each slice to prevent sticking and maintain neat, professional-looking layers.
We hope you enjoy baking and devouring these incredibly satisfying Marshmallow Peanut Butter Rice Krispies Brownies. Happy baking and indulging!
