Marshmallow brownies are a rich and soft chocolate dessert that combines classic brownies with sweet, fluffy marshmallows.
These brownies are known for their gooey texture and extra sweetness, making them a favorite treat for both kids and adults. The base is made from a simple brownie batter, which is baked until soft and slightly chewy.
What makes marshmallow brownies special is the layer of marshmallows added either inside or on top. As the brownies bake, the marshmallows melt and create a soft, sticky layer that adds a fun texture to every bite.
In some recipes, marshmallows are added at the end and slightly toasted, giving a light golden top.

How to Make Marshmallow Brownies
Preheat the oven Start by setting your oven to 180°C (350°F). Allow it to fully heat before baking. This step is important because a properly heated oven helps the brownies cook evenly and gives them the right texture.
Prepare the baking pan Take an 8×8 inch baking pan and line it with parchment paper. You can also lightly grease it with butter. This makes it easier to remove the brownies later without breaking them.
Mix the wet ingredients In a large mixing bowl, add ½ cup melted butter and 1 cup sugar. Mix them well until smooth. Then add 2 eggs and 1 teaspoon vanilla extract. Whisk everything together until the mixture looks creamy and slightly thick.
Add the dry ingredients Now add 1 cup flour, ½ cup cocoa powder, and ¼ teaspoon salt into the same bowl. Mix gently until everything is combined. Do not overmix, as it can make the brownies hard instead of soft.
Add extra flavors If you are using chocolate chips or nuts, fold them into the batter at this stage. This step adds more texture and richness to the brownies.
Pour the batter into the pan Transfer the batter into the prepared baking pan. Use a spatula to spread it evenly so that the brownies bake properly on all sides.
Bake the brownie base Place the pan in the oven and bake for about 20–25 minutes. The edges should look set, while the center remains slightly soft.
Add marshmallows Remove the pan from the oven and sprinkle 1 cup mini marshmallows evenly on top. Make sure they cover most of the surface for a gooey finish.
Bake again briefly Put the pan back in the oven for 5–7 minutes. The marshmallows will start to melt and become soft. They may turn slightly golden on top, which adds a nice look and flavor.
Cool before cutting Take the brownies out of the oven and let them cool in the pan for at least 15–20 minutes. This helps them set properly and makes cutting easier.
Slice and serve Once cooled, lift the brownies out using the parchment paper. Cut into squares and serve. Enjoy the rich chocolate taste with the soft, gooey marshmallow layer in every bite.

Tips for Perfect Marshmallow Brownies
Use good quality cocoa powder The flavor of your brownies depends a lot on the cocoa powder. A rich and smooth cocoa powder will give a deep chocolate taste and better color.
Do not overmix the batter Mix the ingredients just until combined. Overmixing can make the brownies dense and hard instead of soft and chewy.
Measure ingredients correctly Always use proper measuring cups and spoons. Too much flour can make the brownies dry, while too little can affect the structure.
Bake at the right temperature Make sure your oven is fully preheated to 180°C (350°F). Baking at the correct temperature helps achieve even cooking and the perfect texture.
Do not overbake Keep an eye on the brownies while baking. The center should be slightly soft when you take them out. Overbaking will make them dry.
Add marshmallows at the right time Always add marshmallows near the end of baking. This helps them melt properly without burning or becoming too hard.
Let them cool before cutting Cooling is very important. If you cut too early, the brownies may fall apart and look messy.
Line the pan with parchment paper This makes it easy to remove the brownies and keeps them from sticking to the pan.
Customize for extra flavor You can add chocolate chips, nuts, or caramel to make your brownies even more delicious and unique.
Variations and Add-Ons
Chocolate drizzle – Add melted chocolate on top for a rich finish.
Peanut butter swirl – Mix a few spoons of peanut butter into the batter for a creamy taste.
Caramel layer – Drizzle caramel over marshmallows for extra sweetness.
Crunchy nuts – Add walnuts or almonds for a light crunch.
How to Store Marshmallow Brownies
Room temperature – Keep in an airtight container for up to 3 days.
Refrigerator – Store for up to 1 week to keep them fresh longer.
Freezer – Wrap well and freeze for up to 2 months. Thaw before eating.
