Tips & Variations

For extra texture, add chopped pecans or walnuts to the batter before baking.
Use dark cocoa powder for a more intense chocolate flavor.
If you prefer a less sweet frosting, reduce powdered sugar slightly or add a pinch of salt.
For a fudgier brownie, bake slightly less time and check with a toothpick.

Storage

Store brownies in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week, but allow brownies to come to room temperature before serving. Reheat briefly in the microwave if you prefer warm brownies.

FAQs

Can I use regular milk instead of evaporated milk in the frosting?

Yes, you can substitute regular milk, but the frosting may be slightly less rich. Use a little less milk to maintain thickness.

How do I keep the marshmallows from burning?

Keep the marshmallow topping brief in the oven—just 2-3 minutes until they start to melt and brown lightly. Watch closely to prevent burning.

Ingredients

Scale

Brownie Batter

1 cup unsweetened cocoa powder
1/2 cup oil
1/2 cup butter, softened (unsalted)
1 cup granulated sugar
4 large eggs
1 teaspoon vanilla extract
1 cup all-purpose flour
1/2 teaspoon salt

Topping

2 cups mini marshmallows

Frosting

1/2 cup melted butter
1/4 cup unsweetened cocoa powder
1/4 cup evaporated milk
1 teaspoon vanilla extract
3 cups powdered sugar

Instructions

Preheat and prepare pan: Preheat your oven to 350°F and grease a 9×13-inch pan with non-stick cooking spray to ensure easy removal of brownies after baking.
Mix cocoa and oil: In a large mixing bowl, whisk together the oil and cocoa powder until the mixture is smooth and well combined, forming the base for the brownie batter.
Add butter and sugar: Add the softened butter to the cocoa mixture and blend until creamy, then incorporate the granulated sugar to add sweetness and help form a crust during baking.
Incorporate eggs and vanilla: Add the eggs one at a time, mixing thoroughly after each addition, and then stir in the vanilla extract to enhance the chocolate flavor.
Combine dry ingredients: Gently fold in the all-purpose flour and salt, being careful not to overmix to maintain the brownies’ tender texture.
Bake the brownies: Pour the batter into the prepared pan and bake in the preheated oven for 25 to 30 minutes until set but still moist inside.
Add marshmallow topping: Immediately sprinkle the mini marshmallows evenly on top of the warm brownies, then return to the oven for 2 to 3 more minutes until the marshmallows soften and slightly melt.
Cool the brownies: Remove the pan from the oven and allow the brownies to cool completely in the pan to set the layers before frosting.
Prepare frosting: In a bowl, mix together the melted butter, cocoa powder, evaporated milk, and 2 cups of powdered sugar until smooth; gradually add the remaining powdered sugar until you reach your desired frosting consistency.
Frost and serve: Spread the creamy frosting evenly over the cooled brownies, cut into squares, and serve immediately for a luscious treat.

Notes

Do not overmix the batter once flour is added to avoid dense brownies.
Use unsalted butter to control the saltiness in the recipe.
Allow brownies to cool completely before frosting to prevent melting the frosting.
You can substitute mini marshmallows with regular marshmallows cut into smaller pieces if needed.
Store brownies in an airtight container at room temperature for up to 3 days or refrigerate for longer freshness.
