Ingredients You’ll Need
- 1 cup unsalted butter: This forms the luscious base. Unsalted gives you the opportunity to control the salty undertones, but you can substitute with margarine if needed.
- 4 oz semi-sweet chocolate, cut into pieces (or chocolate chips): Adds richness. You can replace it with dark chocolate for a more intense flavor.
- 1 cup granulated sugar: Sweetness and moisture come from this. If you want to reduce sugar, consider using a sugar substitute.
- 1/2 cup brown sugar: This elevates the flavor profile with a subtle caramel undertone.
- 2 tsp vanilla extract: A splash of this enhances the chocolatey goodness. Pure vanilla works best, but you can use imitation if necessary.
- 3 eggs: They provide structure. Room temperature eggs mix in more easily.
- 2/3 cup unsweetened cocoa powder: This is where the chocolate magic happens! Choose a good quality cocoa for more flavor.
- 3/4 cup all-purpose flour: Helps bind everything. This can be swapped with a gluten-free flour blend if needed.
- 2 tbsp cornstarch: This lends to a lighter texture; it’s an important player in achieving the perfect fudgy brownie.
- 1/2 tsp salt: Balances the sweetness. You can reduce this if you prefer.
- 1 cup semi-sweet chocolate chips: For an extra pop of chocolate in every bite.
- 1/2 cup heavy whipping cream: Used in the ganache to give it a decadent, smooth texture. Heavy cream is essential for the right consistency.
- Colored Chocolate Candies: These bring a fun and festive twist, although you can use any sprinkles or toppings you prefer.
- Mini M&Ms: Add a crunch and extra chocolatey goodness—perfect for kids and chocolate lovers alike.
How to Make Cosmic Brownies
- Preheat the Oven: Start by preheating your oven to 350°F (175°C). Line a 9×13 inch pan with parchment paper or grease it well with cooking spray; this ensures easy removal later.
- Melt Butter & Chocolate: In a large bowl, melt 1 cup of unsalted butter and 4 oz of semi-sweet chocolate together in the microwave, using 30-second increments. Stir after each interval until it’s utterly smooth and glossy.
- Mix in Sugars and Vanilla: Whisk in 1 cup of granulated sugar, ½ cup brown sugar, and 2 tsp of vanilla extract until well combined.
- Beat in the Eggs: Add 3 eggs, one at a time, whisking thoroughly after each addition for a velvety batter.
- Incorporate Dry Ingredients: Sift in 2/3 cup cocoa powder, 3/4 cup all-purpose flour, 2 tbsp cornstarch, and ½ tsp salt. Whisk it all together until you have a rich, smooth batter.
- Bake: Pour the batter into the prepared pan and spread it evenly. Bake for about 20 minutes. The top should be set, and a cake tester should come out clean with a few moist crumbs.
- Cool the Brownies: Allow the brownies to cool in the pan for about 20 minutes before frosting them.
- Make the Ganache: Heat ½ cup heavy whipping cream in a saucepan until it’s just below boiling. Pour it over 1 cup semi-sweet chocolate chips placed in a small bowl, then cover this with a towel and let stand for 5-7 minutes.
- Mix Ganache: Once the chocolate has melted, whisk it together until it’s smooth and shiny.
- Top the Brownies: Pour the ganache over the cooled brownies and spread it in an even layer. Optional: Top with colored chocolate candies, mini M&Ms, or sprinkles for that fun cosmic effect.
- Chill: For best results, place the brownies in the fridge for at least 60 minutes before cutting them into delicious squares—15-20 servings, depending on your size preference.
- Store Leftovers: Keep any leftovers refrigerated due to the ganache containing cream.
Storing & Reheating
To store your Cosmic Brownies, keep them in an airtight container at room temperature for up to 2 days. For longer storage, they can be refrigerated for about a week. If you’d like to enjoy them later, freeze the brownies for up to 3 months. Simply thaw in the fridge before serving. If you find they’ve lost a bit of their texture after freezing, a quick 10-second microwave reheat should bring them back to life, though the ganache may soften slightly.
Chef’s Helpful Tips
- Avoid Overmixing: Be gentle when mixing the dry ingredients into the wet. Overmixing can lead to dense brownies.
- Temperature Matters: Always use room temperature eggs. It helps them combine smoothly and creates a better texture.
- Check for Doneness: Test with a toothpick; a few moist crumbs are perfect, but you don’t want raw batter.
- Let Cool Completely: Always cool the brownies before frosting to avoid soupy ganache; patience is key for that clean cut!
- Experiment with Toppings: Don’t hesitate to try different toppings or add-ins like walnuts or caramel bits for an upgrade.
- Make Ahead: You can prepare the batter in advance and bake it later for a quick dessert fix.

With their rich, fudgy texture and delightful toppings, they’re the perfect treat for any occasion.

Recipe FAQs
Can I use different types of chocolate for this recipe?
Absolutely! While semi-sweet chocolate is recommended for that classic rich flavor, you can easily swap it out for dark or milk chocolate based on your taste preferences. Just ensure the chocolate is high quality for the best results.
How do I know when the brownies are done?
The best way to check for doneness is to use a toothpick. Insert it into the brownies; they should be set around the edges but still slightly moist in the center. If it comes out with a few moist crumbs, they’re perfectly baked!
Can I freeze Cosmic Brownies?
Yes, you can freeze them! Wrap the brownies in plastic wrap and store them in a freezer-safe container. They will keep for up to 3 months. Remember to thaw them in the fridge before serving.
What can I use instead of heavy whipping cream for the ganache?
If you’re looking for a lighter alternative, you can use light cream or half-and-half. However, note that the ganache will be less rich. For a non-dairy option, try full-fat coconut milk; it gives a lovely flavor!
