How To Make Cosmic Brownies

As a busy mom with teen boys, I don’t often find the time or motivation for baking. However, this recipe for cosmic brownies is so crazy easy that the whole family fell in love with it!

  • Prepare the oven and pan: Preheat the oven to 350°F. Line a 9×13 inch baking dish with parchment paper that overhangs slightly on the sides.
  • Whip up the brownie batter: In a large bowl, beat together the melted butter, oil, and sugar with an electric hand mixer. Mix in the cocoa powder, eggs, vanilla, and salt, then fold in the flour.
  • Bake the brownies: Pour the batter into the baking dish and smooth it into an even layer. Bake the brownies for 27-32 minutes, then allow them to cool completely.
  • Make the ganache: In a small pot over medium heat, warm the heavy cream until it simmers. Remove the cream from the heat, then stir in the chocolate chips until fully melted.
  • Top the brownies: Spread the ganache over the cooled brownies and sprinkle on the candy chips. Chill the brownies in the fridge for 1-2 hours, then slice and enjoy.

Tips For the Best Cosmic Brownies

Have you ever struggled with brownies that are just… missing something? While testing this recipe, I encountered so many issues — and that’s why I’m sharing these tips to help you avoid making the same mistakes!

  • Opt for a metal baking dish. Metal heats more evenly than glass, resulting in a more consistently fudgy texture. Light-colored metal is ideal, as a darker-colored pan may lead to overcooked edges.
  • Grease and line the baking dish. To keep the parchment paper from slipping around, lightly oil the baking dish. Make sure the paper overhangs on the sides for a hassle-free removal!
  • Use butter and oil in the batter. After plenty of testing, we’ve found that these brownies are best with both butter and oil. Butter adds flavor and fudginess to the brownies, while oil makes them chewy and moist.
  • Chill the brownies. The classic Little Debbie cosmic brownies are wonderfully rich and dense. How do we recreate this texture? After topping the brownies, we recommend refrigerating them for at least an hour (preferably two) to help them solidify.
  • Add a candy crunch. We love these candy coated chocolate chips. However, mini M&Ms or sprinkles work too!
