How to Make Homemade Cosmic Brownies
Quick Overview
Homemade Cosmic Brownies are simple: bake a rich chocolate brownie base, pour on a creamy ganache, top with rainbow chips, and chill until set. You’ll have a tray of chewy, chocolatey bars that are pure joy from start to finish.
Ingredients Overview
- Unsalted Butter: Gives a tender, melt-in-your-mouth texture. Substitute with vegan butter or coconut oil for dairy-free brownies.
- Granulated Sugar: Adds classic sweetness. Coconut sugar can be used for a deeper flavor.
- Brown Sugar: Boosts richness and moisture. If needed, use all granulated sugar.
- Eggs: Essential for binding and that signature fudgy bite. Flax eggs work for egg-free versions.
- Vanilla Extract: Highlights and brightens chocolate notes.
- Cocoa Powder (preferably Dutch-process): Delivers intense, smooth chocolate flavor.
- All-Purpose Flour: Maintains a tender crumb. A gluten-free 1:1 blend works well if needed.
- Salt: Balances sweetness and intensifies the chocolate.
- Heavy Cream (for ganache): Makes the topping ultra-creamy. Coconut cream is a great substitute for dairy-free.
- Chocolate Chips: Use semi-sweet for authentic flavor, or pick dairy-free chips for allergy-friendly brownies.
- Mini Rainbow Chocolate Chips or Candy-Coated Chips: Bring that classic cosmic finish—try naturally colored chips for a healthier option.
Step-by-Step Instructions
- Prepare the Pan: Line an 8×8-inch square baking pan with parchment paper and lightly grease for easy removal.
- Melt Butter and Mix Sugars: Melt butter in a microwave-safe bowl. Stir in both sugars until fully combined and glossy.
- Add Eggs and Vanilla: Beat in eggs one at a time, followed by vanilla extract, for a flavorful, fudgy base.
- Mix Dry Ingredients: Sift cocoa powder, flour, and salt together. Gently fold into the wet mixture—avoid overmixing for tender brownies.
- Bake: Spread the batter evenly in the pan. Bake at 350°F (175°C) for 23–26 minutes. Remove when the center looks slightly underbaked for maximum fudginess.
- Make Ganache: Warm heavy cream until steaming, then pour over chocolate chips. Let sit for 2–3 minutes before stirring to a silky, shiny ganache.
- Frost and Decorate: Once brownies are cool, pour ganache on top, spreading it evenly. Sprinkle rainbow chips while ganache is still soft for that signature cosmic look.
- Chill and Slice: Refrigerate the brownies until the ganache is set, then cut into squares and serve.
Helpful Tips & Customizations
- Don’t Overbake: For irresistibly fudgy Cosmic Brownies, remove from the oven when the center still looks soft.
- Healthier Toppings: Choose naturally colored candy chips or allergen-friendly varieties for a more wholesome treat.
- Dairy-Free Option: Use coconut oil instead of butter and coconut cream in place of heavy cream. Select dairy-free chocolate chips for a fully plant-based version.
- Gluten-Free Swap: Substitute all-purpose flour with a gluten-free 1:1 flour blend.
- Chocolate Lover’s Boost: Fold in extra chocolate chips or chopped chocolate for a double dose of decadence.
