- 1/2 cup melted butter (base for creamy frosting)
- 1/4 cup unsweetened cocoa powder (adds chocolate richness)
- 1/4 cup evaporated milk (gives smooth consistency)
- 1 teaspoon vanilla extract (infuses frosting with flavor)
- 3 cups powdered sugar (thickens frosting, add gradually)
Instructions
- Preheat Oven 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.
- Mix Cocoa and Oil: In a large mixing bowl, whisk together the oil and 1 cup of cocoa powder until the mixture is smooth and well combined.
- Add Butter and Sugar: Add the softened butter to the cocoa-oil mixture and blend until creamy. Then mix in the granulated sugar thoroughly.
- Incorporate Eggs and Vanilla: Add the eggs one at a time, mixing well after each addition to ensure a smooth batter. Stir in the vanilla extract for enhanced flavor.
- Fold in Dry Ingredients: Gently mix in the all-purpose flour and salt, being careful not to overmix to keep the brownies tender and moist.
- Pour Batter and Bake: Pour the batter evenly into the prepared pan and bake in the preheated oven for 25 to 30 minutes, until a toothpick inserted near the center comes out with a few moist crumbs.
- Add Marshmallows and Finish Baking: Remove the brownies from the oven and evenly sprinkle 2 cups of mini marshmallows on top. Return the pan to the oven and bake for an additional 2 to 3 minutes until the marshmallows are soft and slightly melted.
- Cool the Brownies: Allow the brownies to cool completely in the pan on a wire rack, which will help the frosting set properly.
- Prepare the Frosting: In a mixing bowl, combine 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 until the frosting reaches your desired thickness, stirring continuously.
- Frost and Serve: Spread the frosting evenly over the cooled brownies. Cut into squares and serve fresh for a decadent treat.
Notes
- Do not overmix the batter once flour is added to avoid tough brownies.
- Using unsalted butter allows you to control the salt level better.
- Allow brownies to cool completely before frosting for best results.
- Store leftovers in an airtight container at room temperature for up to 3 days.
- For extra gooey marshmallows, you can broil them for 1 minute instead of baking longer, but watch closely to prevent burning.
