Tips & Variations

For an extra fudgy texture, slightly underbake the brownies and let them set as they cool.
Substitute mini marshmallows with chopped nuts for added crunch.
Use salted butter in the frosting to enhance the chocolate flavor and balance sweetness.
Store brownies at room temperature for up to 3 days or refrigerate for longer freshness.

Storage

Store leftover brownies in an airtight container at room temperature for up to 3 days. To keep them moist longer, refrigerate for up to a week. When ready to enjoy, bring brownies to room temperature or warm briefly in the microwave to soften the frosting and marshmallows.

FAQs

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

Yes, you can substitute evaporated milk with regular milk, but the frosting may be slightly thinner and less rich. Adjust the powdered sugar amount to achieve the desired consistency.

How do I prevent the brownies from drying out?

Make sure not to overbake the brownies; check for doneness by inserting a toothpick with a few moist crumbs attached. Also, properly storing them in an airtight container helps retain moisture.

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 easy removal of the brownies.
Combine Oil and Cocoa Powder: In a large mixing bowl, whisk together the oil and the full cup of unsweetened cocoa powder until smooth and well incorporated, creating the chocolate base for your brownies.
Add Butter and Sugar: Add the softened butter to the cocoa mixture and blend until creamy. Then mix in the granulated sugar thoroughly to incorporate sweetness and help form the crust.
Incorporate Eggs and Vanilla: Add the eggs one at a time, mixing well after each addition to ensure a smooth batter. Stir in the teaspoon of vanilla extract to enhance the chocolate flavor.
Mix in Dry Ingredients: Gently fold in the all-purpose flour and salt, being careful not to overmix to maintain a tender brownie texture.
Bake the Brownies: Pour the batter evenly into the prepared pan and bake in the preheated oven for 25 to 30 minutes until set but still moist.
Add Marshmallow Layer: Remove the brownies from the oven and immediately sprinkle 2 cups of mini marshmallows evenly over the top. Return the pan to the oven for an additional 2 to 3 minutes, until marshmallows are soft and beginning to melt.
Cool the Brownies: Allow the brownies to cool completely in the pan on a wire rack to help set the layers.
Prepare the Frosting: In a mixing bowl, combine 1/2 cup melted butter, 1/4 cup unsweetened cocoa powder, 1/4 cup evaporated milk, and 2 cups of powdered sugar. Mix until smooth.
Adjust Frosting Consistency: Gradually add the remaining powdered sugar, mixing well after each addition, until your frosting reaches a spreadable consistency.
Frost and Serve: Spread the creamy chocolate frosting evenly over the cooled brownies. Cut into squares and serve to enjoy delightful, gooey, chocolate-packed treats.

Notes

Do not overmix the flour to avoid dense brownies.
Letting the brownies cool completely before frosting prevents the frosting from melting.
Using unsalted butter allows better control over the saltiness.
You can substitute mini marshmallows with regular-sized ones, roughly chopped.
For a richer taste, use high-quality cocoa powder.
