How to Make Irresistible Cosmic Brownies

Preheat your oven to 350°F (175°C) and line an 8×8 inch baking pan with parchment paper. This ensures easy removal later and gives your brownies a perfect shape and texture.
Melt butter in a large mixing bowl over low heat or in the microwave. Whisk in granulated and brown sugar until the mixture becomes smooth and glossy—this helps to create that rich base!
Incorporate vanilla extract and large eggs, whisking until everything is well combined and shiny. The glossy mixture indicates it’s ready for the dry ingredients!
Sift in cocoa powder, all-purpose flour, and salt; gently fold the dry ingredients using a spatula until fully incorporated. Avoid overmixing; you want your brownies to stay fudgy and soft!
Pour the batter into the prepared baking pan, smoothing the top with a spatula to ensure even baking. The batter should look rich and thick, full of promise for deliciousness!
Bake for 20–22 minutes; check for doneness by inserting a toothpick. It should come out with a few moist crumbs attached—don’t overbake to preserve that fudgy texture!
Prepare the ganache by heating the heavy cream until it’s just simmering. Pour it over the semi-sweet chocolate chips in a bowl, let it sit for a minute, then stir until smooth and silky. This is the crowning glory for your brownies!
Spread the ganache evenly over your cooled brownies, allowing it to cover every inch. Then, sprinkle your choice of candy-coated chocolate chips or rainbow sprinkles on top for a festive finish!
Chill until set, about 30 minutes in the fridge. Once firm, slice into squares and serve. The chilling helps the ganache to perfectly harden, giving you beautiful cuts!

Optional: Serve with a scoop of vanilla ice cream for an extra indulgent treat!

When you’re ready to bake, pour the chilled batter into the prepared pan and proceed with baking; finish by spreading the ganache on top and chilling to set before serving. This way, you’ll enjoy delicious homemade brownies without the last-minute rush!

Expert Tips for Irresistible Cosmic Brownies

Check for Doneness: Insert a toothpick in the center; it should come out with a few moist crumbs. Overbaking leads to dry brownies, so keep a close watch!
Use Room Temperature Ingredients: Eggs and butter mix better when at room temperature, creating a smoother batter for your irresistible Cosmic Brownies.
Don’t Overmix: Gently fold the dry ingredients into the wet ones. Overmixing can result in tough brownies, which lose that luscious, fudgy texture!
Chill for Neat Cuts: After frosting with ganache, refrigerate brownies before slicing. A warm knife helps ensure clean, beautiful edges that showcase your delightful creation.
Experiment with Toppings: Try adding nuts, caramel drizzle, or a mix of chocolate chips for a unique twist. Personalize your cosmic brownies to suit your taste!
