After years of exploring the culinary world through blogging, I’ve had the pleasure of connecting with some truly amazing bakers who have become cherished friends. To celebrate these incredible talents and introduce their magic to my wonderful readers, I’ve invited a select few to share their most tempting creations. Today, we have the distinct honor of hosting Paula from Call Me PMc, a true Southern belle from Mississippi whose passion for baking shines through her extensive collection of dessert recipes.

Meet Our Guest Baker: Paula from Call Me PMc

“Get ready for your taste buds to explode!” exclaims Paula. “This 3 Musketeer Mississippi Mud Cake is absolute chocolate heaven for anyone who considers themselves a true chocoholic. And what better dessert to share as a guest post for the Queen of Chocolate herself? Hi friends, I’m Paula, and I share my culinary adventures and recipes over at CallMePMc.com. A huge thank you to Joan for inviting me to guest post today. As a Southern gal hailing from Mississippi, I’m right there with many of you, juggling a family with strong opinions on food, including a husband who unofficially serves as my food critic and two sons who are equally picky and vocal about their culinary preferences. My goal is always to put easy, delicious, and often nutritious meals on the table.”

Paula’s blog is a treasure trove of diverse recipes, from classic Southern dishes and convenient 30-minute meals to healthy recipes. But, as she confesses with an undeniable enthusiasm, what she reallllllly loves to make are desserts! This passion is palpable, especially when it comes to chocolate.

A Chocoholic’s Confession and the Inspiration Behind the Cake

“I’ll be honest,” Paula continues, “I always have at least two plastic containers and an entire drawer brimming with chocolate. I absolutely despise running out of an ingredient mid-recipe, so I tend to overstock everything. And when chocolate goes on sale after holidays? You bet I’m buying it, whether I ‘need’ it or not, because #onsale is a compelling argument! I might have gone a little overboard after Christmas this year, which is how the ‘chocolate drawer’ came into existence.”

This abundance of chocolate led to a humorous family dynamic. “I told my boys, ‘This chocolate is not for snacking. This is blog chocolate.’ My youngest, Lincoln, looked at me with genuine confusion and asked, ‘What’s blog chocolate?’ ‘It’s for the blog,’ I explained. ‘But, Mom, it’s just chocolate,’ he insisted. ‘No, it’s in the drawer, it’s for the blog!’ At that point, he took my hand, looked me squarely in the eye, and with the utmost sincerity, said, ‘Mom, you do know that chocolate is the same as the other chocolate, right?'” Paula recounts with a laugh.

Whatever the semantic arguments within her household, Paula is happy to report, “At least they don’t snack on the ‘blog chocolate,’ which means I have it readily available to create outrageously decadent desserts like this 3 Musketeer Mississippi Mud Cake just for you!”

The Classic Mississippi Mud Cake, Elevated

Mississippi Mud Cake has long been a Southern staple, celebrated for its rich, dense chocolate base that often resembles a brownie, topped with marshmallows and a generous layer of chocolate frosting or ganache. It’s a dessert that evokes comfort, indulgence, and pure chocolate satisfaction. Paula, like many, grew up loving this classic. “I’ve made Mississippi Mud Cake countless times,” she shares, “along with Strawberry Cake, it was my absolute favorite dessert growing up. But it wasn’t until recently that I had an epiphany: why didn’t I think to add another incredible chocolate layer to my favorite kicked-up brownies before now?”

The addition of 3 Musketeer candy bars is nothing short of genius. These beloved bars, known for their light, fluffy nougat center enrobed in milk chocolate, add a unique texture and a subtle, creamy chocolate note that complements the deep, intense flavor of the brownie and ganache. As the cake bakes and cools, the 3 Musketeer chunks melt slightly into the warm layers, creating pockets of soft, chewy delight that truly set this version apart.

Mastering Your 3 Musketeer Mississippi Mud Cake: Essential Tips

To ensure your 3 Musketeer Mississippi Mud Cake turns out perfectly every time, Paula shares some invaluable tips born from years of baking experience:

Choosing the Right Chocolate for the Brownie Base

Baking Bars vs. Chocolate Chips: “I always opt for semi-sweet chocolate baking bars for this dessert, rather than chocolate chips,” Paula advises. While she prefers not to delve into the ‘geeky side of chocolate,’ she explains, “the bars melt much smoother than chips. This results in a silkier, more uniform chocolate base for your brownie. You’ll typically find chocolate baking bars in the baking aisle alongside chocolate chips and cocoa powder.” For further guidance on achieving that perfect melt, check out her detailed tips on How to Melt Chocolate.

Marshmallow Magic

Size Matters: “I strongly recommend using small miniature marshmallows over the large ones,” Paula stresses. “The big marshmallows are just too bulky for this cake. Stick to the plain minis; avoid any flavored varieties that might clash with the rich chocolate.” The smaller marshmallows melt more evenly and create a perfect gooey layer without overwhelming the other components.

Ingredient Temperature is Key

Room Temperature Essentials: “For the best results, ensure your butter and eggs are at room temperature,” she notes. “Simply take them out of the refrigerator and let them sit on the counter for about an hour before you start mixing. This allows them to incorporate more smoothly into the batter, leading to a more uniform and tender cake.”

Mixing with Care

Avoid Over-Beating: “Lastly, resist the urge to over-beat this mixture,” Paula cautions. “If you’re using an electric mixer, stir on low speed just until everything is combined and smooth, which usually takes about one minute. If you’re going old-school with muscle power and mixing by hand (and I truly respect that!), mix until all ingredients are fully incorporated and smooth, making sure you don’t see any dry pockets of flour or cocoa powder. Over-mixing can lead to a tough, dense cake, and we want a perfectly rich and tender brownie base.”

The Anatomy of Indulgence: Layers of Flavor

This 3 Musketeer Mississippi Mud Cake is a masterpiece of layered delight, each component contributing to its irresistible charm:

The Brownie Base: A thick, fudgy, and intensely chocolatey brownie forms the foundation. Its density and richness provide the perfect counterpoint to the lighter toppings.
Toasted Marshmallows: A blanket of miniature marshmallows, briefly baked to golden perfection, adds a delightful gooey, slightly caramelized texture and a sweet, vanilla-like flavor.
3 Musketeer Candy Bars: Chopped into generous chunks, these candy bars melt into the warm marshmallow layer, offering a creamy, airy nougat texture and a gentle milk chocolate flavor that creates delightful surprises in every bite.
Chocolate Ganache/Frosting: A smooth, glossy, and intensely chocolatey ganache crowns the cake, sealing in the goodness and adding another layer of deep chocolate flavor and a luxurious mouthfeel.

Every element is carefully chosen to create a harmonious blend of textures and an explosion of chocolate goodness. From the first forkful, you’ll experience the satisfying chew of the brownie, the melt-in-your-mouth gooiness of the marshmallows, the tender sweetness of the 3 Musketeers, and the rich embrace of the ganache.

Serving Suggestions and Occasions

This 3 Musketeer Mississippi Mud Cake is truly a showstopper, perfect for any occasion where you want to impress and indulge. Serve it at dinner parties, family gatherings, or as a special treat for weekend dessert. It’s incredibly rich, so small slices often suffice. For an even more extravagant experience, consider pairing it with:

A scoop of vanilla bean ice cream to cut through the richness.
A dollop of freshly whipped cream.
A drizzle of caramel sauce for an added layer of sweetness.
A hot cup of coffee or a cold glass of milk for the ultimate comfort.

No matter how you serve it, this cake is guaranteed to be a hit with chocolate lovers of all ages.

3 Musketeer Mississippi Mud Cake

Prep Time
15 minutes

Cook Time
40 minutes

Total Time
55 minutes

Ingredients

For the Brownie Base:

1 cup butter, at room temperature
4 ounces semisweet chocolate, chopped (baking bar recommended)
2 cups granulated sugar
1 and 1/2 cups all-purpose flour
1/2 cup unsweetened cocoa powder
4 large eggs, at room temperature
1 teaspoon vanilla extract
3/4 teaspoon salt
1 (10.5 ounce bag) miniature marshmallows
6 regular size 3 Musketeer candy bars, chopped into large chunks

For the Chocolate Frosting:

1/2 cup butter
1/3 cup milk
1/3 cup unsweetened cocoa, sifted
4 cups confectioners sugar
1 teaspoon vanilla extract

Instructions

Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius).
Line a 15x10x1 inch sheet pan with foil or parchment paper, ensuring it overhangs slightly for easy removal. Spray the lining generously with non-stick spray.
In a microwave-safe bowl, combine 1 cup of room temperature butter and the chopped semisweet chocolate. Microwave in 30-second intervals, stirring well after each, until fully melted and smooth. Set aside to cool slightly.
In a separate large bowl, combine the granulated sugar, all-purpose flour, unsweetened cocoa powder, and salt. Whisk these dry ingredients together thoroughly.
Once the chocolate mixture has cooled a bit, combine the large eggs and vanilla extract with it. Whisk until well incorporated.
Gradually add the wet egg and chocolate mixture to the dry flour mixture. Mix on low speed (if using an electric mixer) or by hand until just combined and smooth. Be careful not to over-mix, as this can make the brownie tough.
Pour the brownie batter evenly onto the prepared sheet pan. Spread it out gently to cover the entire surface.
Bake in the preheated oven for 20 minutes.
Carefully remove the brownie from the oven. Immediately and evenly spread the miniature marshmallows over the warm brownie layer.
Return the pan to the oven and bake for an additional 8 to 10 minutes, or until the marshmallows are beautifully toasted and golden brown. Keep a close eye on them to prevent burning.
Remove the cake from the oven and, while still warm, immediately sprinkle the chopped 3 Musketeer candy bars over the toasted marshmallows. The residual heat will help them melt slightly.
To Make the Chocolate Frosting: In a small saucepan, combine 1/2 cup butter, 1/3 cup unsweetened cocoa, and 1/3 cup milk over low heat. Cook for 2 to 3 minutes, stirring constantly, until the butter is completely melted and the mixture thickens slightly.
Remove the saucepan from the heat. Add the confectioners’ sugar one cup at a time, whisking vigorously after each addition to combine thoroughly.
Stir in the vanilla extract and continue to whisk until the frosting is smooth and free of lumps.
Pour the warm chocolate frosting evenly over the slightly cooled cake, spreading it gently to cover the top. Allow the cake to cool completely before slicing and serving for the best texture and clean cuts.
