  • For the Brownies:
  • 1/3 cup of unsweetened cocoa powder
  • 1/2 cup of vegetable or canola oil
  • 1/2 cup of softened butter
  • 2 cups of granulated sugar
  • 4 large eggs
  • 2 teaspoons of vanilla extract
  • 1 1/2 cups of all-purpose flour
  • 1 teaspoon of salt
  • 3 cups of mini marshmallows
  • For the Frosting:
  • 1/2 cup of melted butter
  • 1/3 cup of unsweetened cocoa powder
  • 1/3 cup of evaporated milk
  • 1 teaspoon of vanilla extract
  • 3 - 3 1/2 cups of powdered sugar


Step 1: Preheat and Prepare

Preheat your oven to 350 degrees Fahrenheit and grease a 9x13-inch baking pan with non-stick cooking spray.

Step 2: Mix the Cocoa and Oil

In a large mixing bowl, pour the vegetable or canola oil over the unsweetened cocoa powder and mix until well combined.

Step 3: Combine Butter and Sugar

Add the softened butter to the cocoa-oil mixture and mix until smooth. Then, add the granulated sugar and mix for about 1 minute.

Step 4: Add Eggs and Vanilla

Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

Step 5: Incorporate Flour and Salt

Add the all-purpose flour and salt to the batter, stirring until everything is well combined.

Step 6: Bake the Brownies

Pour the brownie batter into the prepared pan. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean.

Step 7: Marshmallow Topping

Remove the brownies from the oven and evenly sprinkle the mini marshmallows over the top. Return the pan to the oven for an additional 2-3 minutes, or until the marshmallows puff up. Remove from the oven and let them cool completely.

Step 8: Prepare the Frosting

While the brownies are cooling, make the frosting. In a mixing bowl, combine the melted butter, unsweetened cocoa powder, evaporated milk, and vanilla extract. Beat with electric beaters until smooth.

Step 9: Add Powdered Sugar

Gradually add powdered sugar, about a cup at a time, mixing well until you reach your desired frosting consistency. You'll typically use about 3 1/4 cups of powdered sugar.

Step 10: Frost and Cut

Once the brownies have cooled, spread the frosting evenly over the top. To make cutting easier, it's recommended to make these brownies a day in advance and refrigerate them before cutting into squares.
