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 richer, smoother flavor)
• 1 1/2 TBSP Cornstarch
• 1/2 tsp Salt
• 1 cup Semi-sweet chocolate chips
• 1 cup Marshmallow creme

Baking the Perfect Brownie Base

The journey to these incredible Marshmallow Brownies begins with crafting the perfect brownie base. We’re aiming for something fudgy, rich, and intensely chocolatey – a canvas that will beautifully complement the sweet marshmallow topping. Don’t rush this stage; the care you put in here will absolutely pay off in the final product.

1. Preheat your oven and prepare your pan: Before we get our hands dirty with batter, let’s get our oven ready. Preheat it to 350°F (175°C). This consistent temperature is crucial for even baking. Next, prepare a 9×13 inch baking pan. I like to grease it thoroughly with butter or non-stick cooking spray, and then line it with parchment paper, leaving an overhang on the sides. This overhang acts as a helpful “sling” to lift the baked brownies out of the pan cleanly, making slicing a breeze. Trust me, struggling to cut brownies in the pan is a frustration you don’t need.
2. Combine wet ingredients and sugar: In a large mixing bowl, whisk together the 2 cups of granulated sugar, 3 large eggs, and 1 egg yolk. Whisk until the mixture is smooth and slightly lighter in color. This step incorporates air into the batter, which contributes to the fudgy texture. Now, pour in the 1/2 cup of melted unsalted butter and the 1/2 cup of oil. The combination of butter and oil creates a wonderfully moist and tender brownie. Add the 2 teaspoons of pure vanilla extract for that essential warm aroma and flavor. Whisk everything together until well combined. You should have a glossy, homogenous mixture.
3. Incorporate dry ingredients: In a separate medium bowl, whisk together the 3/4 cup of all-purpose flour, 1 cup of unsweetened cocoa powder (definitely use Dutch process for its deeper, less bitter flavor), the 1 1/2 tablespoons of cornstarch, and the 1/2 teaspoon of salt. The cornstarch helps to create a tender crumb and prevent the brownies from becoming too cakey. Sift these dry ingredients into the wet ingredient mixture. Gently fold them in with a spatula until just combined. Be careful not to overmix at this stage; overmixing can develop the gluten in the flour, resulting in tougher brownies. A few streaks of flour remaining are perfectly acceptable.
4. Add chocolate chips and bake: Now for the little bursts of chocolatey goodness! Stir in the 1 cup of semi-sweet chocolate chips. These will melt slightly during baking, adding another layer of richness and texture to your brownies. Pour the thick batter into your prepared baking pan and spread it evenly. Now, it’s time to bake! Place the pan in your preheated oven and bake for 25-30 minutes. You’ll know they’re ready when a toothpick inserted into the center comes out with moist crumbs attached, but not wet batter. We’re aiming for fudgy, not dry and overbaked.

The Marshmallow Magic

Once your brownie base is out of the oven, it’s time for the show-stopping marshmallow layer. This is where the magic truly happens and elevates these from great brownies to unforgettable treats.

1. Apply the marshmallow creme: While the brownies are still warm in the pan, immediately spread the 1 cup of marshmallow creme evenly over the top. It’s important to do this while the brownies are warm so the marshmallow creme spreads more easily and begins to melt slightly into the warm brownie. Don’t worry if it’s not perfectly smooth; a slightly rustic look is part of its charm.
2. Toast to perfection: This is the crucial step for that toasted marshmallow flavor and appearance. You have two options here:
   • Broiler Method: If you have a broiler, carefully place the pan under the broiler for 1-2 minutes. Keep a VERY close eye on it, as it can go from perfectly golden to burnt in seconds! You want the marshmallow creme to puff up and turn a beautiful golden brown.
   • Oven Method: Alternatively, you can return the pan to the oven for another 5-7 minutes at 350°F (175°C), or until the marshmallow creme is golden and slightly bubbly. Again, watch it closely to prevent burning.

   Whichever method you choose, the aroma that will fill your kitchen at this point is simply divine.

3. Cool and slice: This is arguably the hardest part – waiting! Let the brownies cool completely in the pan on a wire rack. This allows them to set properly, ensuring clean slices and preventing the marshmallow from becoming too gooey and messy. Once completely cooled, use the parchment paper overhang to lift the entire brownie slab out of the pan. Now, you can slice them into squares. For the cleanest cuts, use a sharp knife, and wipe the knife clean between each slice.

Enjoy these heavenly Marshmallow Brownies with a glass of milk, a cup of coffee, or simply on their own. They are rich, decadent, and utterly irresistible!

Frequently Asked Questions:

Why are my marshmallows not toasting properly on top?

Ensure your oven rack is positioned in the upper third of your oven. You can also turn on your broiler for the last minute or two of baking, watching very carefully to prevent burning. Make sure the marshmallows are spread in a single layer for even toasting.

Can I make these Marshmallow Brownies ahead of time?

Yes, you can bake the brownies and let them cool completely. Store them in an airtight container at room temperature for up to 2-3 days. When you’re ready to serve, you can gently warm them in the oven for a few minutes before topping with marshmallows and toasting. The marshmallow topping is best added closer to serving time for optimal gooeyness.
