Step-by-Step Instructions
1. Prepare the Baking Pan
- Preheat your oven to 350°F (175°C).
- Line an 8-by-8-inch metal baking pan with parchment paper or foil, leaving some overhang for easy removal. Lightly spray the lining with nonstick cooking spray.
Pro Tip: Using parchment paper makes it a breeze to lift the brownies out for cutting later. No sticking, no mess!
2. Make the Brownie Batter
- Melt the Butter: In a large microwave-safe bowl, melt the butter on high for about 90 seconds. Stir it until smooth.
- Mix the Sugars and Cocoa: Stir in the granulated sugar, brown sugar, and sifted cocoa powder until the mixture is well combined. Let it cool slightly if it’s too hot.
- Add Wet Ingredients: Add the vanilla extract, eggs, egg yolk, and corn syrup. Stir until the mixture is glossy and smooth.
- Incorporate Dry Ingredients: Gently fold in the flour, cornstarch, and salt. Mix until just combined—don’t overmix! The batter will be thick and shiny.
Pro Tip: Overmixing can lead to tougher brownies. Stir just until you don’t see streaks of flour.
- Pour and Smooth: Pour the batter into the prepared pan and use a spatula to spread it evenly.
3. Bake the Brownies
- Place the pan in the preheated oven and bake for 25 minutes.
- The edges should look set, but the center might still be slightly underdone. This is what gives the brownies their fudgy texture.
- Remove the brownies from the oven and let them cool completely in the pan.
Pro Tip: Resist the urge to cut them while they’re warm! Cooling ensures they hold their shape when slicing.
4. Prepare the Frosting
- Heat the Cream: Place the heavy cream in a small microwave-safe bowl and heat on high for 1 minute until hot but not boiling.
- Melt the Chocolate Chips: Add the semisweet chocolate chips to the hot cream. Let it sit for 3 minutes to allow the chocolate to melt.
- Stir Until Smooth: Use a spatula or whisk to stir the mixture until smooth and glossy.
5. Frost and Decorate
- Pour the Frosting: Pour the frosting over the cooled brownies and spread it evenly with a spatula.
- Add Toppings: Sprinkle the rainbow candy-coated chocolate chips or your preferred toppings generously over the frosting.
Pro Tip: For even distribution, sprinkle the candy in small handfuls and press gently into the frosting.
- Chill to Set: Refrigerate the brownies for 1 to 2 hours, or until the frosting is firm to the touch.
6. Slice and Serve
- Once the frosting is set, use the parchment overhang to lift the brownies out of the pan.
- Place on a cutting board and use a sharp knife to slice into 12 squares. For cleaner cuts, wipe the knife with a damp cloth between slices.
How to Serve this Homemade Cosmic Brownies
- Classic Presentation: Serve chilled for the ultimate fudgy texture.
- With Ice Cream: Warm a brownie in the microwave for 10 seconds and top with a scoop of vanilla ice cream.
- Party Style: Cut into smaller squares for bite-sized treats perfect for gatherings.
Additional Tips for Success
- Use Good-Quality Cocoa: A high-quality cocoa powder will give your brownies a richer chocolate flavor.
- Don’t Skip the Cornstarch: It’s key to achieving that soft, fudgy consistency.
- Cool Completely Before Frosting: If the brownies are warm, the frosting won’t set properly.
- Store Properly: Keep them in an airtight container to maintain freshness.
- Customize Your Toppings: Have fun with it! Crushed nuts, toffee bits, or coconut flakes can take these brownies in a whole new direction.
Recipe Variations
- Gluten-Free: Swap the all-purpose flour for a gluten-free 1:1 baking mix.
- Dairy-Free: Use vegan butter and coconut cream for the frosting.
- Extra Decadent: Add a layer of caramel between the brownie and frosting.
- Nutty Twist: Stir in 1/2 cup of chopped walnuts or pecans into the brownie batter.
Storing and Freezing
- Room Temperature: Store in an airtight container for up to 3 days.
- Refrigerator: Keep brownies in the fridge for up to 1 week. They’re delicious chilled!
- Freezer: Place brownies on a baking sheet and freeze until solid, then transfer to a freezer-safe container. Freeze for up to 3 months. Thaw overnight in the fridge before serving.
Special Equipment
- Microwave-Safe Bowl: For melting butter and heating cream.
- 8-by-8-Inch Pan: The ideal size for perfectly thick brownies.
