Cocoa powder provides rich flavor: The unsweetened cocoa powder gives these brownies a deep, chocolatey taste that balances perfectly with the sweetness of the marshmallows.

✓

Butter enhances moisture and texture: The melted butter not only adds richness but also helps create a fudgy, dense texture that contrasts beautifully with the fluffy marshmallows on top.

✓

Eggs bind and add structure: The two large eggs in this recipe play a crucial role, providing structure while also helping to create a moist and chewy brownie. I found that using room temperature eggs made a noticeable difference in texture.

Mini marshmallows melt perfectly: The mini marshmallows melt into gooey pockets throughout the brownies, adding a pleasureful contrast to the rich chocolate, and they hold their shape just enough to offer a satisfying texture.

Easy Substitutions

Dairy-free: swap butter for coconut oil — the brownies will have a slight coconut flavor and a more tender texture.
Gluten-free: swap all-purpose flour for a 1:1 gluten-free flour blend — the texture might be a bit denser, but the taste remains delicious.
Lower calorie: swap granulated sugar for a sugar substitute like erythritol — brownies will be less sweet but still satisfying.
Egg-free: swap eggs for flax eggs (1 tbsp ground flaxseed + 2.5 tbsp water per egg) — this will create a slightly denser brownie but still hold together well.

How to Make This Recipe

Prep & Mix

Preheat your oven to 350°F (175°C) and grease a 9x9 inch baking pan. This ensures your brownies won’t stick and will come out perfectly shaped.

In a medium bowl, whisk together cocoa powder, granulated sugar, flour, salt, and baking powder until combined. This creates a uniform dry mixture that will help your brownies rise just right.

In another bowl, mix melted butter, eggs, and vanilla extract until smooth and creamy. The butter adds richness, while the eggs provide structure and moisture.

Combine the wet ingredients with the dry mixture, stirring gently until just combined. Overmixing can lead to dense brownies, so stop when you see a few flour streaks.

Fold in mini marshmallows and semi-sweet chocolate chips gently. This adds gooeyness and bursts of chocolate in every bite. Be careful not to crush the marshmallows!

Bake

Pour the batter into the prepared baking pan and spread it evenly. The even layer helps with consistent baking.

Sprinkle milk chocolate chips on top of the batter before baking. This creates a deliciously melty chocolate layer that’s tempting.

Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. This ensures your brownies are fudgy and not overcooked.

Cool & Serve

Remove the brownies from the oven and let them cool in the pan for 10 minutes. This helps them set up before cutting.

Dust with powdered sugar before cutting into squares and serving. This adds a lovely touch and makes them look even more tempting.

tips_and_updatesTips for Success

Understanding Cocoa Powder's Role

Not all cocoa powders are created equal, and the type you use can significantly impact the flavor of your Chocolate Marshmallow Brownies. I prefer using Dutch-processed cocoa for a smoother, richer taste, but if you go with natural cocoa, it will give your brownies a more intense chocolate flavor. Experiment with both to find your favorite — I made a batch with each and found that Dutch cocoa brought a lovely depth that I just couldn’t resist.

Avoiding the Marshmallow Melt

One common mistake is adding the marshmallows too early in the mixing process. If you mix them in while the batter is too warm, they can dissolve and create a gooey mess instead of staying fluffy in the brownies. To keep those delightful little puffs intact, wait until your batter has cooled slightly before gently folding them in. Trust me; the chewy bites of marshmallows are what make each brownie so tempting.

Pro Tips

Use Room Temperature Ingredients:

Bringing your eggs and butter to room temperature helps create a smoother batter. I used to skip this step, but I've learned that it really enhances the texture of my Chocolate Marshmallow Brownies.

Layer Chocolate Chips and Marshmallows:

Instead of mixing all the chocolate chips and marshmallows into the batter, try layering them. Pour half the batter, add a layer of chocolate chips and marshmallows, and then top with the remaining batter for melty pockets throughout.

Cool Before Cutting:

Allow the brownies to cool completely before cutting them. I made the mistake of slicing them too early once, and they fell apart. Patience is key for clean edges and that perfect fudgy texture.

Use High-Quality Chocolate:

The type of chocolate you choose can enhance your brownies. I always opt for premium quality semi-sweet chocolate chips, which melt beautifully and enhance the overall flavor of my Chocolate Marshmallow Brownies.

Experiment with Add-Ins:

Don't be afraid to get creative! I love adding a sprinkle of sea salt on top before baking for a pleasureful contrast to the sweetness. You could also try adding a swirl of peanut butter or a handful of nuts for extra texture.

Variations & Customizations

Flavor Twists

Peanut Butter Swirl

Before baking, swirl in ½ cup creamy peanut butter into the brownie batter. The result is a rich, fudgy brownie with ribbons of nutty flavor. Each bite offers a pleasureful contrast between the chocolate and the smooth, salty sweetness of peanut butter — a match made in dessert heaven!

Mint Chocolate

Add 1 teaspoon of peppermint extract to the batter and fold in ½ cup crushed mint chocolate candies. The brownies become a refreshing twist, with a cool mint flavor that perfectly complements the chocolate. The vibrant green specks add a pop of color, making them eye-catching as well as delicious.

Seasonal Versions

Pumpkin Spice

Incorporate 1 cup of canned pumpkin puree and 1 teaspoon of pumpkin pie spice into the batter. The brownies turn out moist and cake-like, with a warm, spiced flavor profile that embodies fall. They have a lovely orange hue and are perfect for cozy gatherings.

Cherry Almond

Add 1 cup of chopped maraschino cherries and ½ teaspoon of almond extract to the batter. These brownies take on a sweet, fruity flavor, with a chewy texture from the cherries. The almond aroma enhances the chocolate, making this a pleasureful and unexpected treat!

Storage & Meal Prep

How to Store

Room Temperature

Your Chocolate Marshmallow Brownies can be stored at room temperature for up to 3 days. Keep them in an airtight container to maintain their fudgy texture and prevent them from drying out.

Refrigerator

If you want to extend their life, refrigerate them for up to a week. Make sure to let them cool completely, then wrap each brownie individually in plastic wrap or place them in a container with a tight seal. This prevents them from absorbing any unwanted odors from the fridge.

Freezer

You can freeze these brownies for up to 3 months. For best results, flash freeze them on a sheet pan first, then wrap each piece in plastic wrap and place them in a freezer-safe bag. When you're ready to enjoy, simply transfer them to the fridge overnight to thaw.

Be careful! If you stack them while still warm, they'll get soggy on the bottom, ruining that perfect fudgy texture.

Meal Prep

I recommend doubling the recipe so you have plenty to enjoy throughout the week. Prep them the night before a gathering or on the weekend for fresh treats during the week. Store them in an airtight container, and they’ll stay fresh for about a week in the fridge. To reheat, pop them in the microwave for about 10-15 seconds for that just-baked warmth.

Equipment You'll Need

Essential

9x9 inch baking pan: A sturdy square pan is crucial for even baking. Glass or metal pans work well, but I prefer metal for better heat conduction. Just remember to grease it well to prevent sticking.

Whisk: A good whisk makes a difference in the texture of your batter. It helps incorporate air into the eggs and wet ingredients, leading to a lighter brownie. If you have a balloon whisk, use that for the best results!

Nice to Have

Rubber spatula: This handy tool is perfect for folding in those mini marshmallows and chocolate chips without overmixing. It gently combines ingredients, preventing tough brownies!

Frequently Asked Questions

Can I use milk chocolate instead of dark chocolate?

Yes, you can use milk chocolate, but it will make the brownies sweeter and less rich than using dark chocolate. I recommend reducing the sugar slightly to balance the flavors.

Why did my brownies turn out dry?

Dry brownies often result from overbaking or using too much flour. Make sure to measure your ingredients accurately and check for doneness a few minutes before the recommended time.

Can I make these brownies gluten-free?

Absolutely! You can substitute all-purpose flour with a 1:1 gluten-free baking blend. Just ensure the blend contains xanthan gum for the best texture.

What can I serve with chocolate marshmallow brownies?

These brownies pair wonderfully with a scoop of vanilla ice cream or a dollop of whipped cream. A sprinkle of sea salt on top can also enhance the flavors beautifully.

How can I make these brownies ahead of time?

You can prepare the brownie batter in advance and store it in the fridge for up to two days. Just remember to bring it back to room temperature before baking for the best results.

These Chocolate Marshmallow Brownies are a pleasureful treat that always brings smiles to my family’s faces — the gooey marshmallow on top is simply tempting. For an extra touch, try adding a sprinkle of sea salt before baking to enhance those rich chocolate flavors.
