Ingredients
 

For the Brownies:

  • 10 Tablespoons unsalted butter
  • ¾ cup granulated sugar
  • ⅔ cup brown sugar
  • 2 teaspoons vanilla
  • 2 whole eggs plus 1 egg yolk
  • ¾ cup cocoa powder
  • ¾ cup all purpose flour
  • 1 Tablespoon corn starch
  • ½ teaspoon salt

For the Ganache:

  • we tested the ganache and found using half milk chocolate chips and half semi sweet chocolate chips was more true to the real taste
  • ½ cup heavy whipping cream
  • ¾ cup milk chocolate chips
  • ¾ cup semi-sweet chocolate chips
  • Rainbow candy coated chocolate chips or mini M&M's

Instructions

For the brownies:

  • Preheat the oven to 350*F.
  • Melt butter and place in a microwave safe bowl with the sugar and brown sugar. Whisk to combine. Put in the microwave in 30 second intervals, whisking between each one until smooth. The goal is to dissolve the sugars and end up with a smooth consistency. This should take no more than 3 times of being in the microwave for a total of 90 seconds.

  • Add the vanilla, eggs and egg yolk and whisk vigorously until silky and smooth, about a minute.

  • Add the cocoa powder, flour, corn starch and salt and fold into the wet ingredients just until the white specks of flour disappear. Don't over mix!

  • Pour batter into a greased 8x8 baking dish and bake in a 350*F preheated oven for 24-30 minutes. The top will be crackly and an inserted toothpick should come out clean.

  • Allow to cool on the counter for at least 30 minutes, then cool in the refrigerator another 1-2 hours. Or, cool on the counter 3+ hours.

For the ganache:

  • Measure milk chocolate chips and semi-sweet chocolate chips into a heat safe bowl.
  • Place heavy whipping cream in a heat safe bowl and microwave until hot and bubbly, 60 seconds.

  • Pour whipping cream on top of chocolate chips and allow to sit for 30-60 seconds. Whisk until smooth.
  • Pour ganache over top of the cooled brownies and spread smooth.

  • Allow to cool an additional 30 minutes in the refrigerator or 1 hour on the counter. 
  • Top with rainbow coated chips and enjoy!!

Notes

  • Store in an airtight container in the refrigerator or at room temperature for up to 3 days.
  • Store fresh brownies in an airtight container in the freezer for up to 2 months. Thaw by leaving at room temperature for 1-2 hours then eat immediately.
  • Make sure your butter and sugar mixture is nice and smooth before moving on to the next step.
  • Make sure not to over bake or you will have dry, crumbly brownies. For authentic, rich fudgy brownies, make sure to remove from oven as soon as in inserted toothpick comes out clean or has moist crumbs on it.
  • Allow the brownies to cool completely before adding the ganache. Otherwise the ganache will absorb into the brownies making them into something other than a cosmic brownie.
  • We love to serve these with ice cream and whipped cream for a fun sundae!
