Introduction

Cosmic Brownies are a rich, fudgy treat topped with a smooth chocolate ganache and colorful sprinkles. This delightful dessert is perfect for sharing at parties or enjoying as a special snack anytime you crave chocolate.

A tall stack of six dark chocolate squares is shown, each square topped with a smooth layer of glossy dark chocolate. Brightly colored round sprinkles in green, purple, pink, yellow, orange, and blue are scattered on top and between the layers, adding a playful touch. Each chocolate square has two sections separated by a slight line, and the layers appear thick and moist with a rich chocolate color. The stack sits on a white marbled surface with more sprinkles scattered around, and in the background, a white bowl filled with colorful sprinkles is partially visible.

Ingredients

3/4 cup (168g) unsalted butter, melted
2 cups (414g) sugar
3 large eggs, room temperature
1 teaspoon vanilla extract
1 cup (114g) natural unsweetened cocoa powder
1 cup (130g) all-purpose flour
1/2 teaspoon salt
6 ounces (169g) semi-sweet chocolate chips
6 tablespoons heavy whipping cream
Sprinkles

Instructions

Step 1: Preheat your oven to 350°F (180°C). Grease a 9×13 inch pan or line it with parchment paper that extends above the sides, which helps lift the brownies out for easy cutting. Set the pan aside.
Step 2: In a large bowl, whisk together the melted butter and sugar until well combined.
Step 3: Add the eggs and vanilla extract to the butter and sugar mixture, then whisk until fully incorporated.
Step 4: Add the cocoa powder, flour, and salt. Stir with a rubber or wooden spatula until the batter is thick and well combined.
Step 5: Spread the batter evenly into the prepared pan. Bake for 18-23 minutes. Insert a toothpick into the center; when it comes out with a few moist crumbs, the brownies are done.
Step 6: Allow the brownies to cool to room temperature or just slightly warm. Meanwhile, place the chocolate chips in a medium bowl. Heat the heavy whipping cream until it just starts to boil and pour it over the chocolate. Let it sit for 2-3 minutes, then stir gently until smooth and combined to make ganache.
Step 7: Pour the ganache over the cooled brownies and spread it into an even, thin layer. Sprinkle the top with colorful sprinkles.
Step 8: Refrigerate the brownies until the ganache is firm, which makes cutting easier. Then, cut into squares or rectangles and serve.

Tips & Variations

Use parchment paper with overhanging edges to lift the brownies out easily without breaking them.
For extra fudginess, refrigerate brownies overnight before cutting.
Try using different types of sprinkles or add chopped nuts to the batter for variation.
If you prefer a thicker ganache, reduce the cream slightly or chill it before spreading.

Storage

Store Cosmic Brownies in an airtight container in the refrigerator for up to 4-5 days. They are best served chilled for a fudgier texture but can also be enjoyed at room temperature. To serve, let them sit out for a few minutes if you prefer a softer ganache.

How to Serve

The image shows several rectangular chocolate brownies laid out on a white marbled surface. Each brownie has two layers: a thick, dense, dark brown base with a slightly crumbly texture and a smooth, glossy chocolate topping layer. On top of the chocolate layer, there are small, round, colorful candy balls scattered in shades of purple, green, orange, yellow, pink, and blue. One brownie piece is lifted up, showing the rich, dark brown inside clearly. In the background, there is a white bowl filled with the same colorful candy balls.

FAQs

Can I use salted butter instead of unsalted?

Yes, but reduce added salt slightly to avoid the brownies becoming too salty.

How can I tell when the brownies are perfectly baked?

Insert a toothpick into the center; it should come out with a few moist crumbs but not wet batter.

Ingredients

Scale

Brownie Batter

3/4 cup (168g) unsalted butter, melted
2 cups (414g) sugar
3 large eggs, room temperature
1 teaspoon vanilla extract
1 cup (114g) natural unsweetened cocoa powder
1 cup (130g) all-purpose flour
1/2 teaspoon salt

Chocolate Ganache

6 ounces (169g) semi-sweet chocolate chips (about 1 cup)
6 tablespoons heavy whipping cream

Topping

Sprinkles, for decoration

Instructions

Preheat and prepare pan: Preheat your oven to 350°F (180°C). Grease a 9×13 inch baking pan or line it with parchment paper that extends above the sides for easy removal of the brownies. Set aside.
Mix butter and sugar: In a mixing bowl, combine the melted unsalted butter and sugar. Whisk together thoroughly until the mixture is smooth and well combined.
Add eggs and vanilla: Incorporate the room temperature eggs and vanilla extract into the butter-sugar mixture. Whisk again until fully blended.
Add dry ingredients: Stir in the natural unsweetened cocoa powder, all-purpose flour, and salt using a rubber or wooden spatula. Mix until the batter is uniform and thick.
Bake the brownies: Spread the thick batter evenly into your prepared baking pan. Bake for 18-23 minutes. Check doneness by inserting a toothpick into the center; it should come out with a few moist crumbs but not wet batter.
Prepare the ganache: Once the brownies are baked, allow them to cool to room temperature or just slightly warm. Place the semi-sweet chocolate chips in a medium bowl. Heat the heavy whipping cream until it barely boils, then pour it over the chocolate. Let sit for 2-3 minutes to soften the chocolate, then stir gently until the mixture is smooth and glossy.
Apply ganache and decorate: Pour the prepared ganache evenly over the cooled brownies, spreading it gently to form a thin glaze. Immediately sprinkle your colorful sprinkles over the ganache.
Chill and cut: Refrigerate the brownies until the ganache firms up, which makes cutting easier. Once set, cut into squares or rectangles.
Store properly: Due to the ganache topping, store the brownies in an airtight container in the refrigerator to maintain freshness.
Serve and enjoy: These brownies are delicious served chilled for a fudgier texture or at room temperature. Consume within 4-5 days for best taste.

Notes

Using parchment paper that extends above the sides of the pan makes it easier to lift out the baked brownies and cut them neatly.
Check baking time carefully; overbaking can dry out the brownies. The toothpick test should show moist crumbs, not wet batter.
Heating the cream just until boiling is key to achieving a smooth ganache.
Refrigerating the brownies before cutting helps the ganache firm up for cleaner slices.
Store in the fridge due to the perishable ganache topping, and consume within a few days for best flavor and texture.
