Ingredients:
- 1 1/2 cups white granulated sugar
- 1/2 cup powdered sugar
- 3 large eggs, room temperature
- 1 egg yolk, room temperature
- 1/2 cup unsalted butter, melted
- 1/2 cup canola or vegetable oil
- 1 teaspoon pure vanilla extract
- 3.5 oz semi-sweet chocolate bar, melted
- 1 cup all-purpose flour
- 1 cup unsweetened cocoa powder
- 1 tablespoon cornstarch
- 1 teaspoon salt
- 1 cup semi-sweet chocolate chips
- 1/2 cup heavy cream
- Rainbow candy coated chocolates for topping
For the Cosmic Brownies:
1. Prepare the Chocolate Base
First, let’s get our rich, fudgy brownie base ready. In a large mixing bowl, whisk together the 1 1/2 cups of white granulated sugar and the 1/2 cup of powdered sugar. The powdered sugar will help create a finer texture. Next, add your 3 large eggs and the extra egg yolk. It’s crucial that your eggs are at room temperature for this step; it allows them to emulsify better with the sugar and fats, leading to a smoother, more luxurious batter. Whisk these ingredients vigorously until they become pnon-alcoholic ale yellow and slightly thickened, which usually takes about 2-3 minutes. This aerates the mixture and sets the stage for a tender brownie. Now, pour in your 1/2 cup of melted unsalted butter and the 1/2 cup of canola or vegetable oil. Gently whisk until just combined. Overmixing at this stage can develop the gluten in the flour too much, resulting in a tougher brownie, which we definitely want to avoid for that classic chewy texture. Stir in the 1 teaspoon of pure vanilla extract and the 3.5 oz of melted semi-sweet chocolate bar. Fold these in until everything is nicely incorporated and you have a glossy, chocolatey mixture. Don’t worry if the chocolate isn’t perfectly smooth; small flecks are fine.
2. Combine Dry Ingredients and Fold into Wet
In a separate medium-sized bowl, sift together your 1 cup of all-purpose flour, 1 cup of unsweetened cocoa powder, 1 tablespoon of cornstarch, and 1 teaspoon of salt. Sifting is a vital step here, especially with cocoa powder, as it helps to break up any lumps and ensures that your dry ingredients are evenly distributed. This prevents pockets of dry flour or cocoa in your finished brownies. The cornstarch acts as a binder and helps to create that wonderfully fudgy texture we’re aiming for. Once your dry ingredients are sifted, gradually add them to your wet chocolate mixture. Use a spatula or wooden spoon to gently fold the dry ingredients into the wet. Be careful not to overmix! Mix only until there are no visible streaks of flour remaining. A few small lumps are perfectly acceptable and actually desirable for a fudgy brownie. Remember, gentle folding is key to maintaining the airiness you incorporated earlier and preventing a dense, tough result.
3. Bake the Brownies
Now it’s time to bake these beauties! Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan, or line it with parchment paper, leaving an overhang on the sides to make lifting the brownies out easier once they’re done. Pour your rich brownie batter into the prepared pan and spread it evenly with your spatula. Ensure the surface is as smooth as possible. Place the pan in the preheated oven and bake for approximately 25-30 minutes. To check for doneness, insert a toothpick into the center of the brownies. If it comes out with moist crum extractbs attached, they are perfectly baked. If it comes out clean, they might be slightly overbaked and could be a little dry. If there’s still wet batter, continue baking for a few more minutes and test again. We are aiming for that signature fudgy center!
For the Chocolate Ganache Topping:
4. Prepare the Ganache
While the brownies are cooling, let’s prepare the luscious chocolate ganache that makes these Cosmic Brownies truly out of this world. In a heatproof bowl, place your 1 cup of semi-sweet chocolate chips. In a small saucepan, heat the 1/2 cup of heavy cream over medium heat until it just begin extracts to simmer around the edges. Do not let it boil. Once the cream is hot, pour it directly over the chocolate chips in the bowl. Let it sit undisturbed for about 5 minutes. This allows the heat from the cream to melt the chocolate evenly. After 5 minutes, gently whisk the mixture starting from the center and working your way outwards. Continue whisking until the ganache is completely smooth, glossy, and emulsified. If you find there are still a few unmelted chocolate pieces, you can place the bowl over a double boiler (a bowl set over a pot of simmering water, making sure the bottom of the bowl doesn’t touch the water) for a minute or two, stirring constantly until smooth.
5. Assemble and Decorate
Once your brownies have cooled completely in the pan (this is important for the ganache to set properly and not melt off), it’s time fornon-alcoholic alee grand finale. Pour the smooth chocolate ganache over the cooled brownies. Use an offset spatula or the back of a spoon to spread the ganache evenly across the entire surface of the brownies, reaching all the edges. You want a nice, thick layer. Immediately after spreading the ganache, generously sprinkle the rainbow candy coated chocolates over the top. Distribute them evenly for that iconic “cosmic” look. Gently press them down into the ganache so they adhere well. Allow the ganache to set at room temperature for at least 30 minutes, or pop the pan into the refrigerator for about 15-20 minutes if you’re short on time and want the ganache to firm up more quickly. Once the ganache has set, you can lift the entire brownie slab out of the pan using the parchment paper overhangs. Place it on a cutting board and slice into squares. Enjoy your homemade Cosmic Brownies!

Frequently Asked Questions:
Can I make these Cosmic Brownies ahead of time?
Absolutely! Cosmic Brownies are excellent for making in advance. Once cooled and the ganache has set, store them in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week. They might even taste better the next day as the flavors meld!
What kind of chocolate should I use for the ganache?
For the best flavor and texture in your Cosmic Brownies ganache, we recommend using good quality semi-sweet or bittersweet chocolate chips or a chopped chocolate bar. Using a higher quality chocolate will result in a smoother, richer ganache that truly complements the fudgy brownie base.
