Ingredients

For the Brownie Base

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)
1 1/2 TBSP Cornstarch
1/2 tsp Salt
1 cup Semi-sweet chocolate chips

For the Marshmallow Topping

1 cup Marshmallow creme

How to Make Marshmallow Brownies

Step 1: Preheat the Oven

Preheat your oven to 325°F. Prepare a 9×9-inch baking pan by spraying it with nonstick spray. Line the bottom and two sides of the pan with parchment paper and spray again for easy removal later.

Step 2: Prepare Dry Ingredients

In a medium bowl, sift together the flour, cocoa powder, cornstarch, and salt. Set this mixture aside while you work on the wet ingredients.

Step 3: Mix Wet Ingredients

Using a stand mixer or hand mixer with a whisk attachment, beat together the sugar, eggs, and egg yolk on high speed for about 5 minutes until it turns pale in color. Meanwhile, melt your butter in the microwave and allow it to cool slightly.

Step 4: Combine Wet Ingredients

Add in the oil, melted butter, and vanilla extract into your egg mixture. Mix on low speed until everything is combined. Gradually add in your dry ingredients and mix on low until just combined. Fold in the semi-sweet chocolate chips using a rubber spatula.

Step 5: Add Marshmallow Fluff

Pour your brownie batter into the prepared pan evenly. In a separate bowl, melt the marshmallow fluff in the microwave for about 20-30 seconds until it’s easier to dollop. Use a teaspoon to add dollops of marshmallow fluff on top of your brownie batter. Lightly swirl it into the batter using a butter knife.

Step 6: Bake

Place your pan in the preheated oven and bake for about 45-55 minutes. Check for doneness by inserting a toothpick; it should come out slightly wet but not covered in batter. If necessary, bake for an additional 5 minutes.

Step 7: Cool Down

Once baked, remove from oven and let cool completely on a cooling rack before cutting them into squares to serve.

How to Perfect Marshmallow Brownies

To achieve the ultimate marshmallow brownies, attention to detail is key. Here are some essential tips to ensure your brownies turn out perfectly every time.

Use Quality Ingredients – High-quality cocoa powder and chocolate chips will elevate the flavor of your brownies significantly.
Don’t Overmix – Mixing too much can lead to tough brownies. Just combine until you see no dry flour.
Swirl Gently – When adding marshmallow fluff, use a light hand for swirling. This keeps distinct layers while blending flavors.
Check Baking Time – Every oven is different; keep an eye on the brownies towards the end of baking for perfect doneness.
Let Them Cool Completely – Allowing them to cool fully before cutting helps achieve clean edges and prevents them from falling apart.
Store Properly – Keep leftover brownies in an airtight container at room temperature for up to three days.

Best Side Dishes for Marshmallow Brownies

Pairing side dishes with marshmallow brownies can enhance your dessert experience. Here are some delicious options that complement these fudgy treats.

Fresh Fruit Salad – A mix of seasonal fruits provides freshness and balances richness.

Coffee or Espresso – The bitterness of coffee enhances chocolate flavors and offers a sophisticated pairing.
Cheese Plate – A selection of mild cheeses can create an interesting sweet-savory contrast.
Caramel Sauce – Drizzling caramel over your brownie adds an extra layer of sweetness and decadence.
Tea Selection – Herbal teas such as chai or mint provide warmth and unique complementary flavors.

Common Mistakes to Avoid

When making marshmallow brownies, it’s easy to overlook some essential steps. Here are common mistakes that can affect your final product.

Skipping the Parchment Paper – Not lining the pan with parchment paper can make it difficult to remove the brownies once baked. Always line the bottom and sides for easy removal.
Overmixing the Batter – Mixing too long can lead to dense brownies instead of fudgy ones. Mix until just combined to keep them light and airy.
Using Cold Ingredients – Cold eggs and butter can cause the batter to clump. Always use room temperature ingredients for a smooth mix.
Baking Too Long – Overbaking can dry out your brownies. Check them a few minutes before the suggested baking time to ensure they stay moist.
Not Swirling Enough – If you don’t swirl the marshmallow fluff properly, it may not mix well during baking. Use a gentle hand to create those beautiful swirls.
