Tips & Variations

• Use unsalted butter to better control the saltiness of the brownies.
• For extra richness, add a handful of chopped pecans or walnuts to the batter before baking.
• If you prefer a less sweet frosting, reduce the powdered sugar slightly and add a pinch of salt.
• You can replace mini marshmallows with regular marshmallows cut into smaller pieces if needed.

Storage

Store leftover brownies in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week. For best flavor, allow refrigerated brownies to come to room temperature before serving. Reheating briefly in the microwave can restore the gooey texture.

How to Serve

Serve this delicious recipe with your favorite sides.

FAQs

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

Yes, regular milk can be used, but evaporated milk gives a richer, creamier texture to the frosting. Using regular milk may result in a thinner consistency, so you might need to adjust the powdered sugar accordingly.

How do I know when the brownies are done baking?

Insert a toothpick into the center of the brownies. It should come out with a few moist crumbs but not wet batter. This ensures the brownies stay fudgy but fully cooked.

Ingredients

Scale 1x2x3x

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 for desired consistency)

Instructions

1. 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 ensure easy removal.
2. Mix Cocoa and Oil: In a large mixing bowl, whisk together the oil and 1 cup unsweetened cocoa powder until the mixture is smooth and well combined, creating the chocolate base for the brownies.
3. Add Butter and Sugar: Blend in the softened butter until creamy. Then add the granulated sugar and mix thoroughly to combine the ingredients evenly.
4. 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.
5. Combine Dry Ingredients: Gently fold in the all-purpose flour and salt, making sure not to overmix to keep the batter tender and chewy.
6. Bake Brownies: Pour the batter into the prepared pan, spreading it evenly. Bake for 25-30 minutes until a toothpick inserted near the center comes out with moist crumbs but no raw batter.
7. Add Marshmallows: Immediately sprinkle the 2 cups of mini marshmallows evenly over the hot brownies. Return the pan to the oven for an additional 2-3 minutes, just until marshmallows puff slightly and begin to melt.
8. Cool Completely: Remove the pan from the oven and allow the brownies to cool completely in the pan to set and prevent the frosting from melting.
9. Prepare Frosting: In a bowl, mix together the melted butter, 1/4 cup unsweetened cocoa powder, evaporated milk, and 2 cups of powdered sugar until smooth and creamy.
10. Adjust Frosting Consistency: Gradually add the remaining powdered sugar to the frosting mixture, stirring continuously until the desired thick and spreadable consistency is reached.
11. Frost Brownies: Spread the frosting evenly over the cooled brownies, smoothing the surface with a spatula.
12. Serve: Cut into squares and serve for a decadent, melt-in-your-mouth chocolate treat.

Notes

• For a fudgier texture, slightly underbake the brownies by a couple of minutes but ensure they are fully set at edges.
• Use unsalted butter to control sodium levels and balance sweetness better.
• Do not overmix the flour to avoid tough brownies.
• Cooling the brownies completely before frosting prevents the frosting from melting or becoming runny.
• Store brownies in an airtight container at room temperature for up to 3 days or refrigerate up to a week.
• Mini marshmallows can be substituted with regular sized but may require slightly longer melting time.
