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 and ensure easy removal of the brownies.
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 fully combined, creating a rich chocolate base.
3. Add butter and sugar: Add softened butter to the cocoa-oil mixture and blend until creamy. Then, mix in the granulated sugar thoroughly to help form a sweet crust and add texture.
4. Incorporate eggs and vanilla: Beat in the eggs one at a time, mixing well after each addition for an even consistency. Stir in the vanilla extract to enhance the chocolate flavor.
5. Add dry ingredients: Gently fold in the all-purpose flour and salt, being careful not to overmix to keep the brownies tender and moist.
6. Bake batter: Pour the prepared batter evenly into the greased 9×13-inch pan and bake for 25-30 minutes, or until a toothpick inserted near the center comes out with moist crumbs.
7. Add marshmallows: Remove the brownies from the oven and immediately sprinkle the 2 cups of mini marshmallows evenly over the top. Return to the oven for an additional 2-3 minutes to slightly melt the marshmallows.
8. Cool brownies: Allow the brownies to cool completely in the pan to set the layers before frosting.
9. Prepare frosting: In a mixing bowl, combine melted butter, 1/4 cup cocoa powder, evaporated milk, and 2 cups of powdered sugar. Mix until smooth and creamy. Gradually add the remaining powdered sugar until the frosting reaches your desired thickness.
10. Frost and serve: Spread the frosting evenly over the cooled brownies. Cut into squares and serve for a decadent dessert experience.
