How to Make The Best Cosmic Brownies

Follow these simple steps to prepare this delicious The Best Cosmic Brownies:

Step 1: Preheat and Prepare
Preheat the oven to 350?F (175?C). Line an 8-by-8-inch metal baking pan with parchment paper or foil, then spray with cooking spray for easy removal. This is your canvas, so make sure it?s ready for masterpiece creation.

Step 2: Melt and Mix
In a large microwave-safe bowl, melt the butter for about 90 seconds on high power. Carefully stir in the granulated sugar, brown sugar, and cocoa powder until well combined. If the mixture is still very hot, let it cool slightly before adding in the vanilla extract, eggs, egg yolk, and corn syrup. Stir everything together until it looks like a luscious chocolate potion.

Step 3: Combine Dry Ingredients
Now it?s time to add in the flour, cornstarch, and fine sea salt to the mixture. Stir until just combined?you’ll want a thick batter, so don?t overmix! Pour this rich chocolatey goodness into the prepared pan.

Step 4: Bake to Perfection
Pop the pan into your preheated oven and bake for 25 minutes. Keep an eye on them?you want the tops to look set but still slightly soft in the center. Once they’re baked, let them cool completely in the pan. Patience is key here, but trust me, it’s worth it!

Step 5: Make the Ganache
In a small microwave-safe bowl, heat the heavy cream for about 1 minute on high until it?s steaming. Then, pour in the semisweet chocolate chips. Just let it sit for about three minutes before stirring until smooth and luscious. This is the drizzle of joy that will top off your brownies later.

Step 6: Assemble and Chill
Pour the ganache over the cooled brownies and smooth it evenly over the surface. Now comes the fun part?sprinkle your rainbow candy-coated chocolate chips across the ganache like confetti! Refrigerate for 1 to 2 hours until the ganache is set. When it’s finally time to cut them, just think about all the delighted faces.
