Full Recipe:
1-1/2 cups butter, divided
3/4 cup baking cocoa, divided
4 large eggs, room temperature
2 cups sugar
1 teaspoon vanilla extract
1-1/2 cups all-purpose flour
1/2 teaspoon salt
1 jar (16.3 ounces) chunky peanut butter
1/3 cup 2% milk
10 large marshmallows
2 cups confectioners’ sugar
Directions:
Preheat oven to 350°F (175°C). In a small saucepan, melt 1 cup butter over low heat. Stir in 1/2 cup cocoa until smooth, then remove from heat.
In a large bowl, beat eggs, sugar, and vanilla until blended. In a separate bowl, mix flour and salt, then gradually add to the egg mixture. Add cocoa mixture and beat until smooth.
Spread batter evenly into a greased 15x10x1-inch baking pan. Bake for 18-22 minutes or until a toothpick inserted in the center comes out clean. Cool on a wire rack for 3-4 minutes.
In the meantime, microwave chunky peanut butter on high for about 30 seconds or until softened. Stir and spread evenly over warm brownies. Refrigerate for 45 minutes until set.
For the marshmallow topping, in a heavy saucepan, combine milk, marshmallows, the remaining 1/4 cup cocoa, and remaining 1/2 cup butter. Cook over medium-low heat until melted and smooth. Remove from heat and gradually mix in confectioners’ sugar until creamy.
Spread marshmallow mixture over the chilled peanut butter layer. Refrigerate for at least 30 minutes before slicing into squares.

The Ultimate Indulgence: Layered Chocolate Marshmallow Peanut Butter Brownies
When it comes to the world of desserts, there are classics, and then there are legendary creations that steal the show every single time. The Layered Chocolate Marshmallow Peanut Butter Brownies fall into the latter category. Combining the rich, dense texture of homemade brownies with the creaminess of chunky peanut butter and the light sweetness of a marshmallow glaze, this dessert offers a harmony of textures and flavors that captivate from the first bite.
These brownies aren’t just a treat — they’re an experience. Whether you’re baking for a holiday gathering, a potluck, or simply to indulge yourself on a weekend, these layered delights are bound to become a crowd-favorite in any setting.
A Sweet Symphony of Layers
What sets this brownie recipe apart is its three-layer design, where each layer brings something unique to the table. The bottom layer is a classic chocolate brownie base — dense, rich, and satisfyingly chewy. It offers a strong cocoa flavor that acts as the perfect canvas for what follows.
The second layer, a generous spread of chunky peanut butter, introduces a salty contrast and subtle crunch that balances out the chocolate’s sweetness. This peanut butter layer not only elevates the flavor profile but also adds structure to the dessert, giving it that signature bite and richness.
Finally, the top layer features a glossy marshmallow-cocoa glaze. It’s fluffy, sweet, and slightly gooey, providing the perfect finish that ties everything together. This topping melts into the peanut butter and firms up as it chills, making each bite a cohesive blend of texture and taste.
The Origin of a Crowd-Pleaser
While brownies themselves have a long-standing legacy in American dessert culture, this layered version was born from creativity and a desire to push boundaries. According to the original recipe contributor, the idea came from a friend’s version of a layered brownie, but it was customized with chunky peanut butter for a more satisfying crunch and enhanced flavor.
Over time, this dessert has earned a reputation for being a total crowd-pleaser. It’s the kind of treat that people remember, ask for, and try to replicate. It has become a beloved addition to holiday tables, bake sales, school events, and casual get-togethers alike.
Texture is Everything
One of the most compelling aspects of these brownies is the contrasting texture. You get the fudgy chewiness from the brownie layer, the slightly gritty, thick creaminess from the peanut butter, and the soft, airy sweetness of the marshmallow glaze.
Each bite offers something new — a crunch here, a melt-in-your-mouth moment there — making it a dessert that’s both comforting and exciting. The layering also helps each flavor shine individually while contributing to a cohesive final product.
Texture is an often underestimated factor in baking, but here it becomes one of the defining features. This dessert is proof that when done correctly, textural contrast can elevate even the simplest of ingredients into something extraordinary.
Why This Dessert Works for Any Occasion
Versatility is another hallmark of this brownie recipe. It’s easy to make in large batches, which is ideal for serving a crowd. The chilling time between layers ensures that the dessert sets properly and slices cleanly, making it ideal for presentation on dessert trays.
Because the bars are rich and flavorful, smaller pieces go a long way. This means you can serve more people with a single batch — an excellent option for holiday gifting, party platters, or buffet-style dessert spreads.
Additionally, the layered presentation is naturally eye-catching. The contrast of dark brownie, pale peanut butter, and shiny marshmallow glaze makes for a stunning visual, especially when neatly cut into squares. You don’t need any fancy garnishes or intricate techniques to make them look bakery-worthy.
Tips for Success
To ensure your brownies turn out perfect every time, there are a few key tips to keep in mind:
Use room temperature eggs to achieve the right emulsification and consistency in the batter.
Don’t overbake the brownie layer. It’s done when a toothpick comes out with a few moist crumbs. Overbaking will make it dry.
Allow the peanut butter layer to fully set before adding the marshmallow glaze. This keeps the layers distinct and prevents blending.
Chill before slicing. Refrigerating the finished product makes it easier to cut into neat, clean squares — especially important if you’re serving these for a party or gifting them.
A Balanced Flavor Profile That Appeals to All Ages
One reason why these brownies are so universally loved is their balanced flavor profile. While desserts with rich chocolate or nut butters can sometimes be too intense, the combination of the three layers ensures that no one flavor dominates.
The cocoa offers deep, bittersweet notes; the peanut butter brings savory richness; and the marshmallow glaze lightens everything with its smooth sweetness. The result is a treat that appeals to both kids and adults, chocoholics and peanut butter lovers alike.
You can also experiment with variations — try adding chopped nuts, a swirl of caramel, or using a flavored peanut butter for a new twist. But even without alterations, this recipe is about as close to perfection as you can get.
Storage and Make-Ahead Friendly
Another great thing about this recipe is how well it holds up in storage. The brownies can be made a day in advance and stored in the refrigerator. In fact, the flavor and texture may even improve after a day, as the layers settle and meld together slightly.
You can also freeze the bars — just wrap them tightly in plastic wrap and aluminum foil. When ready to serve, thaw them in the fridge or at room temperature. This makes them a convenient option for prepping ahead during the busy holiday season.
Perfect for Gifting
Looking to impress friends, family, or coworkers with a homemade treat? These brownies are ideal for gift boxes, cookie swaps, or holiday tins. Their clean-cut layers make for an attractive presentation, and their rich flavor ensures they’ll be appreciated by anyone lucky enough to receive them.
To gift, simply place individual squares in mini cupcake liners or stack them in a festive tin with parchment between layers. Add a ribbon or personalized tag, and you’ve got a beautiful and delicious gift that feels thoughtful and luxurious.
Health and Nutrition Note
Let’s be honest — these brownies aren’t designed to be diet food. They’re rich, indulgent, and unapologetically decadent. That said, they offer small servings of satisfaction. With a strong flavor impact in every bite, you don’t need to overindulge to feel satisfied.
For those watching their intake, consider cutting smaller pieces or enjoying them occasionally as a special treat. Some home bakers even experiment with slight modifications — using natural peanut butter, lower-sugar alternatives, or dairy substitutes — though this may change the texture and flavor profile.
Conclusion: A Must-Have in Your Dessert Repertoire
There’s no denying it — Layered Chocolate Marshmallow Peanut Butter Brownies are more than just a sweet treat. They are a celebration of rich flavors, comforting textures, and culinary creativity. Whether you’re a seasoned baker or someone just starting out, this recipe offers the perfect blend of simplicity and wow-factor.
With their gooey chocolate base, satisfying peanut butter heart, and silky marshmallow topping, these brownies manage to hit every note just right. Serve them at your next event, include them in your holiday spread, or keep a stash in the freezer for whenever that dessert craving strikes.
Once you’ve made these once, they’ll likely become a staple in your baking lineup — a go-to recipe that never fails to impress.
