Ingredients

Scale

Brownie Base

  • 1 cup unsweetened cocoa powder
  • 1/2 cup oil
  • 1/2 cup butter, softened (unsalted recommended)
  • 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 (add gradually)

Instructions

  1. 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 prevent sticking.
  2. 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 well combined, forming the chocolate base for the brownies.
  3. Add Butter and Sugar: Add the softened butter to the cocoa and oil mixture and blend until creamy. Then mix in the granulated sugar thoroughly to incorporate sweetness and help create a crust.
  4. Incorporate Eggs and Vanilla: Add the eggs one at a time, mixing well after each addition to ensure even distribution, then stir in the vanilla extract to enhance the chocolate flavor.
  5. Add Dry Ingredients: Gently fold in the all-purpose flour and salt, stirring carefully to avoid overmixing which could make the brownies tough.
  6. Bake the Brownies: Pour the batter evenly into the prepared 9×13-inch pan and place in the preheated oven. Bake for 25 to 30 minutes until almost set but still fudgy.
  7. Add Marshmallow Topping: Remove the pan from the oven and evenly sprinkle the mini marshmallows atop the hot brownies. Return the pan to the oven for an additional 2 to 3 minutes, just until the marshmallows soften and begin to melt slightly.
  8. Cool Completely: Allow the brownies to cool completely in the pan to let the marshmallow layer firm up and the dessert set properly before frosting.
  9. Prepare Frosting: In a clean bowl, combine the melted butter, 1/4 cup unsweetened cocoa powder, evaporated milk, and 2 cups of powdered sugar. Mix until smooth and creamy.
  10. Adjust Frosting Consistency: Gradually add the remaining powdered sugar to the frosting mixture, mixing continuously until you reach your desired thickness and spreadability.
  11. Frost the Brownies: Spread the prepared frosting evenly over the cooled brownies to create a rich, creamy chocolate layer.
  12. Serve: Cut the brownies into squares and serve immediately or store for later enjoyment.

Notes

  • Do not overmix the batter after adding flour to keep brownies tender and moist.
  • Use unsalted butter for better control of salt in the recipe.
  • Allow brownies to cool completely before frosting to prevent melting.
  • For an extra gooey marshmallow top, broil for 1-2 minutes instead of baking the marshmallows.
  • Store brownies in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week.
