Ingredients for brownie recipe with chocolate chips and marshmallows

Twelve ingredients combine to create a brownie masterpiece with crispy crackly tops and gooey marshmallow pockets.

Ingredient Amount Notes
Unsalted Butter 🧈 1 cup Room temperature for smooth mixing
Granulated Sugar 🍚 1 ½ cups Light brown sugar for deeper flavor
Semisweet Chocolate Chips 🍫 1 ½ cups High-quality chips for rich flavor
Mini Marshmallows 🍬 2 cups Standard size for even melting
All-Purpose Flour 🌾 ¾ cup Sifted for even texture
Baking Powder 🧂 ½ tsp Ensures proper rise
Salt 🧂 ½ tsp Kosher salt for balanced flavor
Vanilla Extract 🌿 1 tsp Pure extract for authentic flavor
Large Eggs 🥚 2 whole Room temperature for proper binding
Dark Brown Sugar 🍚 ½ cup Enhances caramelized flavor
Unsweetened Cocoa Powder 🍫 ½ cup Natural cocoa for rich chocolate flavor
Heavy Cream 🥛 ¼ cup For extra moisture and richness

The chocolate chips and marshmallows are non-negotiable for this recipe. Ghirardelli semisweet chocolate chips deliver the best flavor, while mini marshmallows melt into perfect fluffy clouds. For the cocoa powder, Hershey's Special Dark or Valrhona ensures deep chocolate flavor. The butter should be room temperature—cold butter creates lumps, and warm butter can cause the batter to separate. I always measure my flour by weight (5 oz) for accuracy, but if using cups, spoons it in and level off for consistency.

No semisweet chocolate chips? Dark chocolate bars chopped into chunks work beautifully, but adjust the amount to 12 oz total. Marshmallows can be swapped for white chocolate chips if you prefer, though they won't melt as dramatically. Running short on cocoa powder? Melted dark chocolate (6 oz) mixed with 2 tbsp cocoa powder creates a rich substitute. The heavy cream can be replaced with whole milk or buttermilk, though the texture will be slightly less rich. For a gluten-free version, swap the all-purpose flour for King Arthur gluten-free flour blend.

This brownie batter keeps well in the fridge for up to 2 days, so you can prep ahead. For best results, bake immediately after mixing. Once baked, store in an airtight container at room temperature for 3 days or freeze for up to 3 months. To reheat, warm in the oven at 300°F for 5-10 minutes. The marshmallows will soften beautifully when reheated, making this an ideal make-ahead dessert for parties or gatherings.

Step-by-step instructions for perfect brownie magic

Precision matters here—each step builds that signature crunchy top and molten center.

1

Cream Butter and Sugars for Structure

In a stand mixer fitted with the paddle attachment, beat the 1 cup unsalted butter on medium speed until completely smooth and creamy, about 2 minutes. This ensures no lumps remain. Gradually add the 1.5 cups granulated sugar and 0.5 cup dark brown sugar, mixing continuously until the mixture lightens in color and becomes fluffy—this typically takes 3-4 minutes. The sugar should nearly double in volume, creating air pockets that will give your brownies that signature tender crumb.

I press down gently on the butter mixture with a spatula during the first minute to break up any remaining lumps. The reason we wait until the butter is fully emulsified with the sugars is that cold butter absorbs into the flour instead of creating that gorgeous, moist texture we're after. If your butter is too cold, the mixture will look grainy—this is your signal to let it sit at room temperature for another 10-15 minutes before proceeding.

2

Incorporate Eggs and Flavorings

Add the 2 whole large eggs, one at a time, mixing on low speed for 30 seconds after each addition until fully incorporated. The mixture should become slightly thicker and ribbon-like when you lift the paddle. Stir in the 1 tsp vanilla extract and 0.25 cup heavy cream, mixing just until combined—overmixing here can develop gluten and make the brownies tough.

Next, sift in the 0.75 cup all-purpose flour, 0.5 tsp baking powder, 0.5 tsp salt, and 0.5 cup unsweetened cocoa powder all at once. Mix on low speed for 30-45 seconds until just combined—you should still see some dry flour streaks. This step is critical: overmixing develops gluten, which leads to a dense, cake-like texture instead of the fudgy, rich brownie we want. Real talk: if your mixer starts to sound like it's fighting the dough, you've mixed too long.

3

Fold in Chocolate and Marshmallows

Remove the bowl from the mixer and gently fold in the 1.5 cups semisweet chocolate chips and 2 cups mini marshmallows using a silicone spatula. Work quickly but carefully to avoid melting the marshmallows prematurely. The chocolate chips should be evenly distributed throughout the batter, while the marshmallows should remain whole—this ensures that signature gooey pockets when baked. If you're worried about the marshmallows sticking, dip the spatula in warm water before folding to prevent clumping.

At this stage, the batter will look thick and almost dry, but don't be tempted to add more liquid. The marshmallows will release moisture as they melt in the oven, creating that perfect balance of texture. For even better results, press the batter into a 9x9-inch baking pan lined with parchment paper, spreading it evenly to about ½-inch thickness. The edges should be slightly thicker than the center—this creates the classic brownie shape with a thicker, denser middle.

4

Bake to Crunchy-Gooey Perfection

Preheat your oven to 350°F and bake the brownies for 22-25 minutes. The key here is to bake until the edges are set and the top is deep golden brown, but the center still looks slightly underdone. You want that signature crackly top—when you press gently on the center with your finger, it should feel soft but spring back slightly. If you're unsure, insert a toothpick into the center: it should come out with a few moist crumbs, not completely clean.

Here's where the magic happens: once the brownies are out of the oven, let them cool in the pan for 10 minutes before transferring to a wire rack to cool completely. This resting period allows the marshmallows to fully melt and the chocolate to set just enough to hold its shape. If you cut into them too soon, the marshmallows will ooze out everywhere. For the ultimate experience, serve them at room temperature—this is when the textures truly shine.

Pro Tips For Making Brownie Recipe With Chocolate Chips And Marshmallows

  • Melt Butter Slowly: I learned this the hard way—dumping cold butter into a hot pan makes it splatter like a science experiment gone wrong. Instead, cut the butter into small cubes first, then melt it over medium-low heat until it’s just liquid. This keeps the sugar from burning when you add it later, and your brownies won’t taste like charred caramel.
  • Toast the Marshmallows: Skip the raw marshmallows—they’ll turn into a sad, sticky mess. Spread them evenly over the batter after baking, then broil for 1-2 minutes until they’re golden and puffed. Watch them like a hawk, though; they go from perfect to burnt faster than you can say “oops.”
  • Don’t Overmix the Batter: Stir just until the flour disappears—any more, and you’ll end up with tough, cakey brownies instead of fudgy perfection. The moment you see streaks of dry flour, stop. Overmixing is the fastest way to ruin a rich, gooey texture, and no one wants that.
  • Use Room-Temp Eggs: Cold eggs sink and create uneven pockets in the batter, leading to lumpy brownies. Let them sit out for 30 minutes before cracking them in—this ensures a smooth, consistent texture. Trust me, your future self will notice the difference when every bite is uniform.

Wine and beer pairings for this dish

Sweet Wine Pairings

For these rich, fudgy brownies, opt for dessert wines that complement the chocolate and marshmallow flavors without overpowering them. A glass of Moscato d'Asti from Italy brings bright acidity and floral notes that cut through the sweetness beautifully.

I love pairing it with these brownies because its effervescence cleanses the palate between bites. Another fantastic choice is Riesling from Germany, particularly a semi-sweet version like Dr. Loosen Blue Slate, which offers honeyed apple and citrus flavors that harmonize with the caramelized edges of the brownies. 🍷

Creamy Port Selection

If you're serving these as a decadent after-dinner treat, a tawny Port like Graham's 10-Year-Old is a perfect match. The nutty, caramelized notes in the Port mirror the deep chocolate flavor in the brownies, while its smooth texture enhances the marshmallow's gooey texture.

For a lighter option, try a Ruby Port—its fruity, berry-like flavors provide a refreshing contrast to the richness of the dessert. Serve chilled to let the flavors truly shine.

Craft Beer Pairings

For beer lovers, a Belgian-style witbier like Hoegaarden or Stella Artois works surprisingly well. The coriander and citrus notes in these beers balance the sweetness of the marshmallows and chocolate, creating a delightful contrast.

If you prefer something darker, a milk stout like Sweet Stout from Guinness complements the brownie's richness with its creamy, chocolatey profile. The carbonation helps cleanse the palate between bites, making each mouthful of brownie even more enjoyable. 🍺

Coffee or Espresso

If you're not a fan of wine or beer, a strong cup of espresso or cold brew is an excellent alternative. The bitterness of the coffee enhances the chocolate flavors in the brownies, while the warmth of the espresso adds a comforting touch.

For an extra indulgent experience, try a cortado—the velvety microfoam balances the sweetness of the marshmallows without overpowering the brownie's rich texture. It's a simple yet sophisticated pairing that elevates the dessert experience.

Chilled Sparkling Water

For those who prefer a non-alcoholic option, a sparkling water with a splash of lime can be surprisingly refreshing. The effervescence helps cut through the richness of the brownies, while the citrus note adds a bright contrast.

I like to add a few drops of vanilla extract to the sparkling water for an extra touch of sweetness that complements the marshmallows. It’s a light yet effective way to enjoy these brownies without the heaviness of alcohol or coffee. ✨

Frequently asked questions

1

Why do my marshmallows turn hard instead of staying gooey?

This happens when the brownies cool too quickly. Let them rest in the pan for 15-20 minutes after baking to allow the marshmallows to fully melt and set properly. Overbaking also causes this—pull them out when the edges are set but the center still jiggles slightly. For extra gooeyness, store leftovers in an airtight container with a slice of bread to keep them moist.

2

Can I make these brownies gluten-free?

Yes! Replace the all-purpose flour with a 1:1 gluten-free baking flour blend like King Arthur's. For best results, add ½ tsp xanthan gum to help bind the texture. Keep the rest of the recipe identical—just be sure to measure the gluten-free flour by weight for accuracy. The texture will be slightly denser but still delicious.

3

What's the best way to cut these brownies?

Use a hot, clean knife for clean cuts. Dip the knife in hot water, wipe dry, then cut through the brownies. This prevents sticking and gives you those perfect, crisp edges. For extra presentation, chill the brownies for 30 minutes before cutting to set the marshmallows slightly. Cut into 16 squares for standard servings or 9 larger pieces for a more generous portion.

4

How can I make these brownies less sweet?

Reduce the granulated sugar by ¼ cup and replace it with an extra ¼ cup cocoa powder for deeper chocolate flavor. You can also swap ½ cup of the marshmallows for white chocolate chips, which are less sweet. For a more balanced taste, add ½ tsp instant espresso powder to enhance the chocolate notes without adding sweetness.

5

Can I bake these in a different pan size?

Yes, but adjust the baking time. For an 8x8-inch pan, bake 20-22 minutes (thinner batter), and for a 9x13-inch pan, bake 25-28 minutes (thicker batter). Always check for doneness with a toothpick—it should come out with moist crumbs. Line all pans with parchment paper for easy removal. The edges will be thicker in larger pans, so cut wider squares to maintain the same texture ratio.
