Tips & Variations

Use unsalted butter to control the saltiness in the brownies and frosting.
For extra texture, sprinkle chopped nuts such as pecans or walnuts on top before adding marshmallows.
Swap mini marshmallows for large ones, but reduce baking time to prevent over-browning.
For a richer frosting, add a tablespoon of cream cheese before whisking the ingredients.

Storage

Store leftover brownies in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to one week or freeze for up to 3 months. Reheat refrigerated brownies briefly in the microwave for 10-15 seconds to soften the frosting before serving.

FAQs

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

Yes, you can substitute regular milk, but evaporated milk adds a creamier texture and richer flavor to the frosting.

How do I prevent the brownies from becoming dry?

Be careful not to overbake; the brownies should be moist inside. Also, avoid overmixing the batter to keep them tender and fudgy.

Ingredients

Scale

Brownie Batter

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

Topping and Frosting

2 cups mini marshmallows
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 (175°C) and grease a 9×13-inch baking pan with non-stick cooking spray to ensure the brownies do not stick.
Mix cocoa and oil: In a large mixing bowl, whisk together the oil and 1 cup of unsweetened cocoa powder until the mixture is smooth and uniform in texture.
Add butter and sugar: Add the softened butter to the cocoa-oil mix and blend until creamy. Then stir in the granulated sugar thoroughly to combine.
Incorporate eggs and vanilla: Add the eggs one at a time, mixing well after each addition to maintain a smooth batter. Stir in the vanilla extract to enhance the chocolate flavor.
Add dry ingredients: Gently fold in the all-purpose flour and salt, being careful not to overmix to keep the brownies tender.
Bake the brownies: Pour the batter evenly into the prepared baking pan and bake in the preheated oven for 25-30 minutes, or until a toothpick inserted near the center comes out with a few moist crumbs.
Add marshmallows: Remove the brownies from the oven and evenly sprinkle the 2 cups of mini marshmallows on top. Return the pan to the oven for an additional 2-3 minutes, until the marshmallows are soft and slightly melted.
Cool completely: Let the brownies cool completely in the pan on a wire rack before frosting.
Prepare frosting: In a separate bowl, combine the melted butter, 1/4 cup cocoa powder, evaporated milk, and 2 cups of powdered sugar. Mix until smooth.
Adjust frosting consistency: Gradually add the remaining powdered sugar (about 1 cup more) until the frosting reaches a spreadable consistency.
Frost the brownies: Spread the frosting evenly over the cooled brownies.
Serve: Cut the brownies into squares and serve. Enjoy the rich, gooey chocolate goodness!

Notes

Do not overmix the batter after adding flour to avoid tough brownies.
Use unsalted butter for better control over saltiness in the final product.
Ensure brownies are completely cooled before frosting to prevent melting the frosting.
Store brownies in an airtight container to keep them fresh for up to 3 days.
Mini marshmallows create the gooey top, but regular marshmallows can be chopped and used if mini size is unavailable.
