- ¾ cup packed light brown sugar: Adds moisture and a subtle caramel flavor.

- 1 teaspoon vanilla extract: For that warm, comforting flavor.
- 1¼ cups unsweetened cocoa powder: Use Dutch-processed for a richer taste, but regular cocoa works fine too.
- 1 cup + 2 tablespoons all-purpose flour: Gives structure; don’t overmix at this stage to keep brownies fudgy.
- ½ teaspoon salt: Enhances overall flavor.
- 8 ounces bittersweet chocolate, chopped: Adds deep chocolate flavor. You can use semi-sweet as an alternative.

How to Make Cosmic Brownies
Preheat Your Oven: Start by heating your oven to 350℉. Line a 9×13-inch pan with parchment paper, allowing it to hang over two sides for easy removal later.
Mix Wet Ingredients: In a large bowl, whisk together the 1 cup (2 sticks) of salted butter and the 1½ cups granulated sugar as well as the ¾ cup packed light brown sugar until combined. Next, whisk in the 4 large beaten eggs, 2 tablespoons light corn syrup, and 1 teaspoon vanilla extract until well incorporated.
Combine Dry Ingredients: In a separate bowl, sift together the 1¼ cups unsweetened cocoa powder, 1 cup + 2 tablespoons all-purpose flour, and ½ teaspoon salt. Gradually stir this mixture into the wet ingredients, mixing until just fully combined.
Bake the Brownies: Scrape the brownie batter into the lined pan, smoothing the top evenly. Bake in the preheated oven for 28 to 32 minutes. The edges should be just set while the center remains slightly fudgy. A toothpick inserted should come out with moist crumbs attached.
Cool Completely: Remove the pan from the oven and let it cool completely on a wire rack. Once cooled, lift the brownies out of the pan using the parchment paper and place them on a cutting board.
Prepare the Ganache: In a medium glass bowl, combine the 8 ounces chopped bittersweet chocolate, 1 tablespoon light corn syrup, and a pinch of kosher salt. Heat the ½ cup heavy whipping cream until bubbling and pour it over the chocolate. Allow this to sit for 1-2 minutes before whisking until smooth.
Top the Brownies: Spread the chocolate ganache evenly over the cooled brownies. Sprinkle with candy-coated chocolate chips for extra crunch. Place the brownies in the fridge to chill before cutting into squares.
Storing & Reheating
Store your Cosmic Brownies at room temperature in an airtight container for up to 3 days. If you prefer them chilled, they can also be kept in the refrigerator for a week, but allow them to come to room temperature before serving for the best texture. You can freeze these brownies for up to 3 months, layering them with parchment paper in a freezer-safe container. When you’re ready to enjoy, simply thaw them in the fridge or at room temperature. If the texture feels a bit firmer after freezing, pop them in the microwave for 10-15 seconds to refresh their fudgy goodness.

Chef’s Helpful Tips
- Check your oven’s accuracy: Oven temperatures can vary, so consider using an oven thermometer for precise baking.
- Room temperature ingredients create a smoother batter, so allow your eggs and butter to sit out for a bit before you start.
- Avoid overmixing — the less you mix the dry ingredients into the wet, the fudgier your brownies will be.
- If using two types of chocolate, aim for a good blend to create depth of flavor.
- For extra indulgence, consider adding chopped nuts or swirl in some peanut butter or Nutella before baking.
There’s nothing like a homemade batch of Cosmic Brownies to satisfy sweet cravings and bring people together. Whether you’re snacking solo on a rainy day or serving them at a bustling gathering, they promise joy and happiness in every bite. So, gather your ingredients and let your kitchen flourish with the delightful aroma of chocolate. Enjoy experimenting with these brownies — who knows, you might just find your new favorite twist on an old classic!
