Ingredients for Marshmallow Brownie Recipe

1 cup unsalted butter
2 cups granulated sugar
4 large eggs
1 teaspoon vanilla extract
1 cup all-purpose flour
1 cup unsweetened cocoa powder
1/2 teaspoon salt
2 cups mini marshmallows

Ingredient Notes and Substitutions

Unsalted butter: Used for a rich flavor; you can substitute with margarine if needed.
Granulated sugar: Sweetens the brownies; brown sugar can add a hint of caramel flavor.
Eggs: Provide structure; you can use flax eggs for a vegan version.
All-purpose flour: Helps bind the ingredients; gluten-free flour works well too.
Unsweetened cocoa powder: Delivers deep chocolate flavor; carob powder is a suitable alternative.

How to Make Marshmallow Brownie Recipe

Step 1: Preheat the Oven

Start by preheating your oven to 350°F (175°C). This ensures that the brownies bake evenly and rise beautifully.

Step 2: Prepare the Baking Pan

Grease your 8×8 inch baking pan with butter or line it with parchment paper. This will prevent the brownies from sticking and make cleanup a breeze.

Step 3: Melt the Butter

In a saucepan over low heat, melt the butter. This step brings out the rich flavor and smooth texture of the brownies.

Step 4: Mix the Sugar and Eggs

In a mixing bowl, combine the melted butter and granulated sugar. Add the eggs one at a time, whisking until the mixture is smooth and glossy.

Step 5: Add Vanilla and Dry Ingredients

Stir in the vanilla extract, then sift in the flour, cocoa powder, and salt. Mixing them well ensures there are no lumps and creates a fudgy texture.

Step 6: Pour into the Pan

Spread the brownie batter evenly into the prepared baking pan. This helps with even baking and ensures every bite is delicious.

Step 7: Bake the Brownies

Bake in the preheated oven for 20 minutes. You want them to be just set but still a bit soft in the center for that perfect brownie texture.

Step 8: Add Marshmallows

After 20 minutes, remove the brownies from the oven and sprinkle the mini marshmallows on top. Return them to the oven for an additional 5 minutes until the marshmallows are puffy and golden.

Pro Tip: For extra flavor, add chocolate chips to the batter before baking.

Tips for the Best Marshmallow Brownie Recipe

Use high-quality cocoa powder for a richer taste.
Do not overmix once you add the flour; it can make the brownies tough.
Let the brownies cool before cutting to get clean edges.
Experiment with toppings like chocolate drizzle or crushed nuts.
For a deeper flavor, add a pinch of espresso powder to the batter.

Common Mistakes to Avoid

Overbaking the brownies will result in a dry texture.
Not greasing the pan properly can lead to stuck brownies.
Using cold eggs can affect the batter; room temperature is best.
Skipping the sifting step can leave you with cocoa lumps.
