Ingredients

Scale

Brownie Batter

  • 1 cup unsweetened cocoa powder (Adds deep chocolate flavor)
  • 1/2 cup oil (Keeps brownies moist)
  • 1/2 cup butter, softened (Use unsalted for better control)
  • 1 cup granulated sugar (Sweetens mix and helps create a crust)
  • 4 large eggs (Bind ingredients and add richness)
  • 1 teaspoon vanilla extract (Enhances chocolate flavor)
  • 1 cup all-purpose flour (Provides structure, don’t over-mix)
  • 1/2 teaspoon salt (Balances sweetness)
  • 2 cups mini marshmallows (Creates a gooey layer)

Frosting

  • 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

  1. Preheat and prepare pan: Preheat your oven to 350°F and grease a 9×13” pan with non-stick cooking spray to prevent sticking and ensure easy removal.
  2. Mix oil and cocoa: In a large mixing bowl, whisk together the oil and cocoa powder until smooth, forming a rich chocolate base.
  3. Add butter and sugar: Add the softened butter and blend until creamy. Then mix in the granulated sugar until combined for sweetness and texture.
  4. Incorporate eggs and vanilla: Add the eggs one at a time, mixing thoroughly after each addition, then stir in the vanilla extract to enhance the chocolate flavor.
  5. Add dry ingredients: Gently fold in the flour and salt, taking care not to overmix to maintain a tender crumb.
  6. Bake the brownies: Pour the batter into the prepared pan and bake for 25-30 minutes until set and slightly pulling away from the edges.
  7. Top with marshmallows: Sprinkle mini marshmallows evenly on top and return to the oven for an additional 2-3 minutes to melt them slightly, creating a gooey top layer.
  8. Cool the brownies: Remove from oven and allow the brownies to cool completely in the pan before frosting for best texture.
  9. Prepare frosting base: In a bowl, mix together the melted butter, cocoa powder, evaporated milk, and 2 cups of powdered sugar until smooth and well combined.
  10. Adjust frosting consistency: Gradually add the remaining powdered sugar until you reach your desired thick and spreadable frosting consistency.
  11. Frost the brownies: Spread the frosting evenly over the cooled brownies using a spatula or knife.
  12. Serve: Cut the frosted brownies into squares and serve. Enjoy the rich, gooey, and creamy dessert.

Notes

  • Do not overmix the batter after adding flour to keep the brownies tender and moist.
  • Use unsalted butter for better control over salt content.
  • You can substitute mini marshmallows with regular marshmallows cut into smaller pieces if preferred.
  • Allow the brownies to cool fully before frosting to prevent melting.
  • Store leftovers in an airtight container for up to 4 days at room temperature or refrigerate to extend freshness.
