  • ¾ cup brown sugar 160 grams
  • ½ cup granulated sugar 100 grams

For the Ganache

  • cups semisweet chocolate chips 255 grams
  • ½ cup heavy cream 114 grams
  • ¼ cup rainbow candy-coated chocolate chips 43 grams, for topping

Instructions

  • Preheat oven to 350°F. Line a 9x9-inch baking pan with a parchment sling. Spray with nonstick spray and set aside.

  • Add the vanilla extract and whisk again.
    1 teaspoon pure vanilla extract
    chocolate sauce in a glass bowl on a white background.
  • With a wooden spoon or spatula, stir in the flour, cocoa powder, and salt.
    ¾ cup all-purpose flour, ¼ cup Hershey’s Special Dark Cocoa Powder, ¼ teaspoon kosher salt
    chocolate mixture
  • Spread the batter out in your prepared pan and bake for 20-25 minutes, until the top is set and a toothpick inserted into the center comes out with a few moist crumbs.

  • Transfer the pan to a wire rack to cool for 30 minutes. Cover and place in the fridge to cool for 1-2 hours until no longer warm to the touch.
  • Once the brownies are cool, make the ganache. Add the chocolate chips to a medium bowl. Heat the cream in a small saucepan until it is steaming and starting to bubble around the edges of the pan. Pour the cream over the chocolate and let sit for 1-2 minutes. Whisk until smooth.

Notes

  • You can use a neutral oil, such as vegetable, canola, or coconut oil, in place of the butter, but your brownies may not turn out as soft.
  • If using salted butter, omit the kosher salt.
  • Feel free to use milk or dark chocolate chips in place of the semisweet in the brownies and/or the frosting to make these brownies to your taste.
  • You can use all brown sugar in place of the granulated sugar for a richer flavor.
  • You can substitute regular cocoa powder for the Special Dark, but note that the brownies will not be as dark or rich.
  • Feel free to add up to 1 cup of mix-ins to these brownies, such as chocolate chips or nuts.
  • In place of the rainbow candy-coated chocolate chips, you can use mini M&M's or rainbow sprinkles.
  • Do NOT skip lining your pan. A parchment paper sling will help you to more easily remove the brownies from the pan.
  • Make sure your chocolate and butter mixture is warm, but not hot, when added to the eggs and sugar. Adding it while it is hot will cook the eggs and create a lumpy batter.
  • Use room temperature eggs to prevent sudden temperature shock, which could cook the eggs as well.
  • Let the brownies cool completely before frosting them; otherwise, the frosting will melt off and could crack as it cools.
  • To cut these brownies cleanly, dip a knife in hot water, then wipe it off between slices.
Storage: Store cosmic brownies in an airtight container in the refrigerator for up to 5 days or in the freezer for up to 2 months.
