Making Cosmic Brownies

Creating Cosmic Brownies is a delightful process that brings the whole kitchen to life with the sweet scent of chocolate. It’s a straightforward recipe where you’ll mix, bake, and indulge in your masterpiece. Let’s walk through the steps together!
- Preheat the oven to 350 degrees F. This is the perfect temperature to bake brownies evenly without drying them out. I always make sure to let the oven heat up fully before putting in my pan.
- Line a 9″ x 9″ square pan with parchment paper, ensuring there’s an overhang on both sides. This will make it easier to lift the brownies out after they’ve cooled.
- Coat the lined pan with cooking spray. This extra step guarantees that your brownies won’t stick to the parchment.
- In a large mixing bowl, add the granulated sugar and unsalted butter. Using a hand mixer, beat the mixture together until it’s light and fluffy, which should take about 1 minute. The more air you incorporate, the lighter your brownies will be.
- Add the eggs and vanilla extract to the bowl. Beat these ingredients in for about 2 to 3 minutes until the mixture becomes pale yellow and thick. You’re looking for a creamy, luscious batter here!
- Next, sift in the all-purpose flour, cocoa powder, and salt. Mix on low speed until all the ingredients are just incorporated. Be careful not to overmix, as this can lead to dense brownies.
- Pour in the milk and continue to beat until the batter is smooth. You want a thick yet pourable consistency, so feel free to scrape down the sides of the bowl to ensure everything is well mixed.
- Pour the batter into the prepared pan, using a spatula to spread it into an even layer. Take your time with this to ensure uniform cooking.
- Bake in the preheated oven for 20 to 25 minutes. Keep an eye on them; the brownies are done when a toothpick inserted in the center comes out clean or with just a few crumbs attached.
- Once baked, let the brownies cool in the pan for about 10 minutes. Then, carefully remove them using the parchment paper overhang.
- For the ganache, place the heavy cream in a medium bowl. Microwave it in 20-second increments until it’s hot but not boiling. This is crucial for melting the chocolate.
- Add the chopped semi-sweet chocolate and milk chocolate to the hot cream. Let this sit for a minute to soften the chocolate before stirring until smooth. This creates a luscious ganache that will top your brownies.
- Stir in the butter and vanilla extract until melted and combined. This step adds richness and flavor to your ganache.
- Pour the chocolate ganache over the top of the brownies, using a spatula to spread it into an even layer. Don’t skimp on this delicious topping!
- Add a generous sprinkle of rainbow chip sprinkles on top of the chocolate while it’s still wet, ensuring they adhere perfectly.
- Chill the brownies in the refrigerator until they set, which can take about 2 hours or overnight for best results. This step is key to achieving that perfect slice.
- Once set, lift the brownies out of the pan using the parchment paper, cut them into squares, and prepare for compliments!
Things Worth Knowing
- Cooling is Key: Letting your brownies cool completely before cutting ensures clean, neat squares.
- Variations: Add nuts or different types of chocolate chips for a unique twist on your Cosmic Brownies.
- Check Oven Temperature: Use an oven thermometer to ensure your oven is at the right temperature; an inaccurate oven can lead to underbaked or overbaked brownies.
- Storing: Keep brownies in an airtight container to maintain freshness. You can also freeze them for later enjoyment!
