It’s the ultimate comfort food, perfect for sharing (or not!) and guaranteed to disappear in a flash. This recipe strikes a beautiful balance between deep chocolate flavor and that irresistible sweet, airy topping. Let’s get baking!

Ingredients:

• 2 cups White granulated sugar
• 3 Large eggs
• 1 Egg yolk
• 1/2 cup Unsalted butter (melted)
• 2 tsp Pure vanilla extract
• 1/2 cup Oil (canola or vegetable)
• 3/4 cup All-purpose flour
• 1 cup Unsweetened cocoa powder (Use dutch process cocoa powder for a deeper, smoother chocolate flavor)
• 1 1/2 TBSP Cornstarch
• 1/2 tsp Salt
• 1 cup Semi-sweet chocolate chips
• 1 cup Marshmallow creme

Let’s Get Baking!

This recipe is designed to be straightforward, but paying attention to a few details will ensure you achieve those perfect, gooey results. We’ll start by creating the rich chocolate brownie base, then introduce the delightful marshmallow swirl, and finally bake them to chewy perfection.

Step 1: Preheating and Preparing Your Pan

First things first, let’s get our oven ready. Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). This consistent temperature is crucial for even baking. Next, you’ll need an 8×8 inch baking pan. To ensure your brownies come out cleanly without sticking, generously grease the pan with butter or baking spray. For an extra layer of insurance and easy cleanup, I highly recommend lining the pan with parchment paper, leaving some overhang on the sides. This “sling” method will allow you to lift the entire slab of brownies out of the pan once cooled, making cutting a breeze.

Step 2: Crafting the Rich Brownie Batter

In a large mixing bowl, we’re going to combine our wet ingredients and sugar. Add the 2 cups of granulated sugar, 3 large eggs, and the single egg yolk. Whisk these together vigorously until the mixture is smooth and slightly lighter in color. The egg yolk is a secret weapon for extra fudgy brownies, adding richness and chewiness. Now, gradually whisk in the 1/2 cup of melted unsalted butter and the 1/2 cup of oil. The oil contributes to the incredible moistness of these brownies, ensuring they don’t dry out. Finally, stir in the 2 teaspoons of pure vanilla extract. Vanilla is a flavor enhancer, making all those chocolate notes sing even louder.

Step 3: Incorporating the Dry Ingredients for Deep Chocolate Flavor

In a separate medium-sized bowl, combine your dry ingredients. This is where the magic happens for that intense chocolate flavor. Add the 3/4 cup of all-purpose flour, the 1 cup of unsweetened cocoa powder (definitely use Dutch-process for its smoother, less acidic taste and deeper color), the 1 1/2 tablespoons of cornstarch, and the 1/2 teaspoon of salt. Whisk these dry ingredients together thoroughly to ensure everything is evenly distributed. The cornstarch is key here; it helps to create a denser, chewier texture in the brownie. Now, gradually add these dry ingredients to your wet ingredients, mixing until just combined. Be careful not to overmix at this stage. Overmixing can develop the gluten in the flour, leading to tougher brownies. A few streaks of flour are perfectly acceptable; they’ll disappear during baking.

Step 4: Adding the Chocolatey Goodness and Preparing for the Swirl

Once your batter is just combined and looks thick and fudgy, gently fold in the 1 cup of semi-sweet chocolate chips. These chips will melt slightly during baking, creating little pockets of even more intense chocolatey goodness throughout your brownies. Spread about two-thirds of this brownie batter evenly into your prepared baking pan. Now comes the star of the show – the marshmallow! Dollop spoonfuls of the 1 cup of marshmallow creme over the brownie batter in the pan. Don’t worry about making it perfectly even; in fact, leaving little gaps will allow the brownie batter to peek through and create beautiful swirls.

Step 5: The Marshmallow Swirl and Baking to Perfection

Now, take the remaining one-third of your brownie batter and carefully dollop it over the marshmallow creme. Using a butter knife or a toothpick, gently swirl the brownie batter and marshmallow creme together. You want to create beautiful ribbons and marbled patterns, but avoid over-swirling, which can mix everything too much and dilute the distinct layers. Aim for a marbled effect. Place the pan in your preheated oven. Bake for 25-35 minutes. The baking time will vary depending on your oven. You’ll know they’re ready when the edges are set and the center is still slightly gooey. A toothpick inserted into the center should come out with moist crumbs attached, not wet batter. Overbaking will result in dry brownies, so keep a close eye on them.

Once baked, remove the brownies from the oven and let them cool completely in the pan on a wire rack. This is perhaps the hardest part – the waiting! Cooling allows the brownies to set properly and become that perfectly fudgy texture we desire. Resist the urge to cut into them while warm, as they will be too soft and may fall apart. Once completely cool, use the parchment paper overhang to lift the entire slab out of the pan. Cut into squares and prepare for pure bliss. These Marshmallow Brownies are a testament to the simple, yet profound, joy of chocolate and marshmallow combined. Enjoy every single bite!

Conclusion:

These Marshmallow Brownies are truly a dream come true for any chocolate lover. The perfect balance of rich, fudgy brownie and gooey, melted marshmallow creates an irresistible dessert that’s both comforting and decadent. They’re incredibly simple to make, making them an ideal treat for beginners or for a quick fix when a chocolate craving hits. The contrast in textures – the chewy brownie base and the airy, sweet marshmallow topping – is what really sets these apart and makes them so addictive. I’ve found them to be a huge hit at parties, potlucks, or simply for a cozy night in.

For serving suggestions, these are fantastic served warm, perhaps with a scoop of vanilla ice cream to amplify the deliciousness. They also keep surprisingly well at room temperature, making them great for bake sales. If you’re feeling adventurous, consider adding a sprinkle of sea salt on top of the melted marshmallow for a sophisticated sweet-and-salty kick, or swirl in some caramel sauce before baking for an extra layer of indulgence. I highly encourage you to give these Marshmallow Brownies a try – I promise you won’t be disappointed!

Frequently Asked Questions:

How do I prevent the marshmallow from browning too much?

Keep a close eye on your brownies during the last few minutes of baking. If the marshmallow is browning faster than you’d like, you can loosely tent the pan with aluminum foil. This will protect the marshmallow from direct heat while allowing the brownie base to finish baking.

Can I make these ahead of time?

Yes, absolutely! These Marshmallow Brownies can be made a day or two in advance. Store them in an airtight container at room temperature. They are delicious at room temperature, but for an extra gooey experience, you can gently rewarm individual servings in the microwave for a few seconds.
