Step 1: Preheat and Prepare the Pan

Preheat your oven to 350°F (175°C). Prepare your baking pan by lining it with parchment paper or greasing it with non-stick cooking spray. This step ensures that your brownies will come out easily once they’ve cooled.

Step 2: Mix the Wet Ingredients

In a large bowl, whisk together the melted butter and sugar until well combined. Add the eggs one at a time, mixing thoroughly after each addition. Then, stir in the vanilla extract.

Step 3: Add the Dry Ingredients

In a separate bowl, sift together the flour, cocoa powder, salt, and baking powder. Gradually add the dry mixture into the wet ingredients, stirring until just combined. Be careful not to overmix, as this can result in a dense texture.

Step 4: Add the Milk

Pour in the milk and mix until smooth. The batter should be thick but spreadable.

Step 5: Bake the Brownies

Pour the brownie batter into the prepared pan and spread it evenly. Bake in the preheated oven for 20-25 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs (not wet batter). Keep an eye on the brownies towards the end of baking to avoid overbaking.

Step 6: Prepare the Chocolate Topping

While the brownies are baking, heat the heavy cream in a small saucepan over medium heat until it just begins to simmer. Remove from heat and stir in the semi-sweet chocolate chips. Let the mixture sit for a minute, then stir until the chocolate is fully melted and the topping is smooth.

Step 7: Top the Brownies

Once the brownies are done, remove them from the oven and let them cool for about 10-15 minutes in the pan. Pour the chocolate topping over the slightly cooled brownies and spread it evenly. Immediately sprinkle the colorful candy-coated chocolates on top for that signature cosmic look.

Step 8: Cool and Serve

Allow the brownies to cool completely on a wire rack or in the pan. Once cooled, slice them into squares and serve. Enjoy the rich chocolate flavor and colorful fun of these homemade cosmic brownies!
