Ingredients

Chocolate Brownies:

  • 1 1/2 cups Butter (3 sticks, melted)
  • 3 cups Sugar
  • 1 Tablespoon Vanilla Extract
  • 1 cup Unsweetened Cocoa Powder
  • 5 large Eggs
  • 1 1/2 cups Flour
  • 3/4 teaspoon Baking Powder
  • 3/4 teaspoon Salt

Chocolate Frosting:

  • 1/2 cup Butter (1 stick, melted)
  • 1/2 cup Cocoa Powder
  • 1/4 cup Light Corn Syrup
  • 3 cups Powdered Sugar
  • 1 teaspoon Vanilla Extract
  • 3 to 4 Tablespoons Milk or Heavy Cream

Instructions

  • Preheat your oven to 350 degrees. Line a 9x13-inch pan with parchment paper, leaving an overhang on two sides for easy lifting or lightly spray with non-stick cooking spray. I suggest using an aluminum pan and not a glass pan.  
  • Melt the butter in the microwave in a microwave-safe bowl or in a pot over medium-low heat. In a mixing bowl, whisk melted butter and sugar until smooth. Add in cocoa powder and vanilla. Add eggs and vanilla, whisking until fully combined. Fold in flour, baking powder, and salt until just incorporated.
  • Pour the batter into the 9 x 13 pan, spreading evenly. Bake for 28-35 minutes, or until a toothpick inserted in the center comes out with moist crumbs (not wet batter). Overbaking will result in dry brownies, these brownies have a fudgy texture. Let cool.

Chocolate Frosting:

  •  While the brownies are cooling, melt butter in a saucepan over low heat. Stir in cocoa powder, milk, vanilla extract, and corn syrup until smooth. Gradually add powdered sugar, whisking until the frosting is thick and glossy. Add more milk or cream, if needed to create a silky smooth consistency.
  • Spread the frosting evenly over the cooled brownies. Allow the brownies to cool fully before cutting.

Notes

    • Why do you suggest NOT using a glass pan when baking brownies or other dessert bars? The edges of brownies in a glass pan often bake more quickly than the center, as the retained heat can cause over-browning or crisping around the edges.
    • How do I know when brownies are done baking?
      Insert a toothpick into the center of the brownies. For these fudgy brownies, it should come out with moist crumbs, not wet batter.
Store frosted brownies in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week.
To freeze the frosted brownies -- place cut brownies on a baking sheet and freeze until solid. Wrap each brownie in plastic wrap and store in a freezer-safe bag for up to 3 months. Thaw at room temperature before serving.
