How to Make Ingredients – Brownies:

Step 1: Prepare Your Pan and Preheat

Set the mood by preheating your oven to 350°F (175°C). Grease a 9×13-inch baking pan, then line it with parchment paper so you can lift out those cosmic treats with zero sticking later.

Step 2: Whisk the Wet Ingredients – Brownies:

In a large mixing bowl, whisk together the melted butter, granulated sugar, and brown sugar until well combined and just a little glossy. Crack in the eggs one at a time with a steady hand, mixing well after each addition, then add your vanilla extract. This creates a dreamy, gooey batter base—don’t rush, it’s worth savoring the aroma already!

Step 3: Incorporate the Dry Ingredients – Brownies:

Sift in the unsweetened cocoa powder, salt, and all-purpose flour. Gently fold everything together just until you no longer see streaks of flour. Overmixing at this stage is the #1 way to make brownies cakey rather than fudgy, so take it easy. The Ingredients – Brownies: come together in a thick, luscious batter.

Step 4: Bake to Fudgy Perfection

Spread the brownie batter evenly into your prepared pan, coaxing it gently into the corners for even baking. Slide the pan into the oven and bake for 25 to 28 minutes—look for set edges and a moist center (a toothpick should come out with just a few crumbs). Let the brownies cool completely in the pan so they set up nice and dense.

Step 5: Make the Ganache Topping

For the velvety ganache, warm your heavy cream until it just begins to simmer. Pour it over the chocolate chips in a medium bowl and let sit for a minute to melt. Then stir—the chips will transform into a glossy, dreamy ganache that glides over the cooled brownies like a chocolate cloud.

Step 6: Decorate with Rainbow Chips and Chill

Spread the ganache generously over the cooled brownies, then shower the top with plenty of rainbow chip sprinkles—don’t hold back! Chill in the fridge for at least 1 hour to set the ganache, making slicing (and sharing) tidy and satisfying.

How to Serve Ingredients – Brownies:

Garnishes

A flourish of extra rainbow chip sprinkles just before serving makes these brownies absolutely irresistible. For a grown-up twist, try a light dusting of cocoa powder over the ganache for contrast, but the classic chips are truly what brings the Cosmic Brownie vibe to life.

Side Dishes

Balance all that rich chocolate with sips of ice-cold milk or a steaming mug of coffee. For a full dessert spread, serve alongside simple vanilla ice cream—that creamy-cold combo with warm, chewy brownies is hard to beat. A handful of fresh berries or sliced banana lightens things up too.

Creative Ways to Present

Cut Ingredients – Brownies: into neat squares, triangles, or even fun cosmic shapes using cookie cutters—perfect for lunchboxes or parties. Stack them in layers with extra ganache for a cosmic brownie ‘cake,’ or wrap single brownies in parchment and neon ribbon for a retro-style treat bag.

Make Ahead and Storage

Storing Leftovers

Ingredients – Brownies: keep their chewy magic when stored in an airtight container at room temperature for up to 4 days, or in the fridge for up to a week. Separate layers with wax paper if stacking so the ganache doesn’t stick.

Freezing

For longer keeping, freeze completely cooled brownies (sliced or unsliced) by wrapping tightly in plastic wrap and then foil. They stay fresh for up to 2 months. Thaw in the fridge overnight, then let come to room temp for that just-baked taste.

Reheating

If you love brownies slightly warm, pop a square in the microwave for just 10–15 seconds to revive that fudgy center and loosen up the ganache (add ice cream on top for a decadent treat). Avoid overheating to maintain their perfect texture.

FAQs

Can I use a different size pan?

Absolutely! If you use a smaller pan, like an 8×8-inch, your Ingredients – Brownies: will be thicker and may need a few extra minutes in the oven. Keep an eye out for doneness cues and adjust as needed.

Can I substitute the rainbow chip sprinkles?

Totally! While classic rainbow chips give Cosmic Brownies their signature look, you can use mini chocolate chips, regular sprinkles, or even chopped candy if that’s what you have on hand.

What’s the best cocoa powder for this recipe?

Go for unsweetened natural cocoa powder for that deep, classic chocolate flavor. Dutch-processed works too if you prefer a smoother, darker brownie—just use a brand you love since the cocoa flavor really shines.

Can I make these Ingredients – Brownies: gluten-free?

Yes! Substitute your favorite 1:1 gluten-free flour blend for the all-purpose flour. The brownies will still be chewy and rich, and no one will know the difference.

Why do I need to chill the brownies before slicing?

Chilling lets the ganache set up into a silky, sliceable layer and makes cutting into clean bars a breeze. Plus, the flavors actually develop more as they rest, so they taste even better!
