Ingredients You’ll Need

The beauty of this Cosmic Brownies Recipe lies in its straightforward ingredients, each chosen to build that perfect balance of fudginess, sweetness, and texture. From the deep cocoa powder to the rainbow candy-coated chocolate chips, every element plays a starring role in creating these irresistible brownies.

  • ¾ cup all-purpose flour: The base that gives structure to your brownies; use gluten-free 1-to-1 flour if needed for a gluten-free version.
  • â…” cup unsweetened cocoa powder: Provides that rich chocolate flavor and dark color essential for fudgy brownies.
  • 12 tablespoons unsalted butter (melted): Adds moisture and richness; salted butter can be used if you skip adding kosher salt.
  • 1 cup granulated sugar: Sweetens the batter; brown sugar can be swapped for a deeper caramel note.
  • ½ cup brown sugar: Adds moisture and a subtle molasses flavor that complements the cocoa beautifully.
  • 2 large eggs: Bind the ingredients and contribute to a tender crumb.
  • 1 teaspoon pure vanilla extract: Enhances all the chocolatey goodness with warming vanilla notes.
  • ¾ teaspoon kosher salt: Balances the sweetness and intensifies the chocolate flavor.
  • 1 cup chocolate chips: Creates a dreamy, melty frosting; choose milk, semi-sweet, or dark depending on your preference.
  • ½ cup heavy cream: Combined with chocolate chips to make a smooth frosting that’s luscious and velvety.
  • ¼ cup rainbow candy-coated chocolate chips: The star topping that brings vibrant color and a fun crunch; mini M&M’s or rainbow sprinkles work beautifully here.

How to Make Cosmic Brownies Recipe

Step 1: Prepare Your Pan and Oven

Start by preheating your oven to 325°F and preparing a 9×9-inch baking pan. Spraying it lightly with nonstick spray and lining it with parchment paper ensures your brownies release easily once baked, making your life a whole lot easier.

Step 2: Mix Dry Ingredients

In a medium bowl, whisk together the flour and cocoa powder until well combined. This step is crucial because it helps evenly distribute the cocoa, preventing clumps and ensuring each bite is richly chocolatey.

Step 3: Combine Butter and Sugars

In a larger bowl, whisk the melted butter with the granulated and brown sugars. This mixture is where the magic begins; the butter’s richness combined with the sugars’ sweetness forms the luscious base of your brownie batter.

Step 4: Add Eggs, Vanilla, and Salt

Next, whisk in the eggs, vanilla extract, and kosher salt. These ingredients bind your batter together while enhancing flavor layers, especially that kiss of vanilla that complements the chocolate so well.

Step 5: Fold in the Dry Ingredients

Gently stir the flour and cocoa mixture into the wet ingredients until just combined. Be careful not to overmix, as too much stirring can develop the gluten and result in tougher brownies rather than the tender, fudgy texture we’re aiming for.

Step 6: Spread Batter Into Pan

Pour your rich batter into the prepared pan and use a spatula to spread it out evenly. This ensures a uniform bake, so every piece is beautifully consistent.

Step 7: Bake the Brownies

Bake in your preheated oven for about 30 to 35 minutes. The trick to perfect cosmic brownies is to pull them out when a toothpick inserted comes out nearly clean—meaning a few moist crumbs should cling to it, highlighting that delicious fudginess.

Step 8: Make the Chocolate Frosting

While the brownies bake, heat the heavy cream in a small pot over medium heat until it just begins to simmer. Remove from heat and add the chocolate chips, stirring steadily until you have a glossy, smooth chocolate frosting that’s just waiting to be spread.

Step 9: Frost and Decorate

Once the brownies have cooled completely, pour the chocolate frosting over the top and smooth it out with a spatula. Immediately sprinkle on the rainbow candy-coated chocolate chips, giving these brownies their signature cosmic sparkle and texture.

Step 10: Chill For the Perfect Finish

Pop your frosted cosmic brownies into the refrigerator or freezer to help the frosting set firmly. This final step sharpens the flavors and gives you those clean edges that make serving so satisfying.

Garnishes

While the rainbow candy-coated chips are the show-stopping garnish, feel free to add a light dusting of powdered sugar or a few edible glitter sprinkles to amp up the cosmic vibe before serving. A fresh mint leaf or a dollop of whipped cream also pairs beautifully for an extra touch of elegance.

Side Dishes

Cosmic brownies shine best as the star of the show, but pairing them with a scoop of vanilla ice cream or a drizzle of caramel sauce elevates the experience to dessert heaven. For a balanced treat, serve alongside fresh berries or a simple fruit salad to cut through the richness.

Creative Ways to Present

For parties, cut the brownies into bite-sized squares and serve them on colorful platters arranged in star or galaxy shapes to echo the cosmic theme. Wrapping individual pieces in parchment paper tied with a shiny ribbon also makes a delightful gift or party favor.

Make Ahead and Storage

Storing Leftovers

Wrap leftover brownies tightly in plastic wrap or store them in an airtight container at room temperature for up to 3 days. Keeping them covered preserves moisture and maintains that luscious fudgy texture.

Freezing

These brownies freeze wonderfully. To freeze, wrap individual pieces or the entire pan tightly with plastic wrap and then foil to prevent freezer burn. They’ll keep well for up to 3 months and thaw quickly at room temperature.

Reheating

If you’re craving a warm Cosmic Brownie, a quick zap in the microwave for 15 to 20 seconds brings back that soft, gooey magic—just watch that frosting doesn’t overheat and melt away its cosmic charm!

FAQs

Can I make this Cosmic Brownies Recipe gluten-free?

Absolutely! Simply substitute the all-purpose flour with a certified gluten-free 1-to-1 baking flour, and you’ll still get those fudgy, decadent brownies without compromising flavor or texture.

What type of chocolate chips should I use for the frosting?

You can choose from milk, semisweet, or dark chocolate chips depending on your taste preference. Milk chocolate offers a creamier sweetness, while dark chocolate delivers a richer, more intense flavor. Semisweet is a nice middle ground.

Is it necessary to refrigerate the brownies after frosting?

Refrigerating helps the chocolate frosting set firmly and keeps the rainbow chips from melting or sliding off. While not absolutely required, it makes cutting and serving tidier and enhances the overall texture.

Can I substitute the rainbow candy-coated chips?

Yes! Mini M&M’s or rainbow sprinkles are excellent alternatives that keep the playful, colorful look and provide that delightful crunch on top of the frosting.

How do I know when the brownies are perfectly baked?

The best test is to insert a toothpick around the 30-minute mark. If it comes out with moist crumbs but not wet batter, your Cosmic Brownies Recipe is perfectly fudgy and ready to cool.

Final Thoughts

There’s something truly special about a recipe that feels both nostalgic and delightfully fun, and this Cosmic Brownies Recipe hits all those notes perfectly. Rich, fudgy, and topped with a festive pop of color, it’s bound to become a go-to recipe for any occasion.
