Each component plays its part, from the rich Dutch-process cocoa powder that intensifies the chocolate notes to the buttery base that ensures a tender chew.

• Semisweet chocolate for ganache: Finely chopped chocolate melts smoothly to create a luscious, creamy center.
• Heavy cream: Heated and combined with chocolate to form the silky ganache filling.
• All-purpose flour: Forms the sturdy base of the cookie dough, providing structure.
• Dutch-process cocoa powder: Adds intense chocolate flavor with a deep, rich color.
• Baking soda: Helps the cookies rise just enough for a tender, chewy texture.
• Kosher salt: Balances sweetness and enhances all the chocolate flavors.
• Chopped semisweet chocolate for dough: Creates little pockets of melty chocolate within the cookie.
• Unsalted butter: Adds richness and a smooth texture to the dough.
• Brown sugar: Adds moisture and chewiness with subtle caramel notes.
• Granulated sugar: Provides crisp edges and sweetness.
• Large eggs: Bind the ingredients while adding moisture and richness.
• Vanilla extract: Lifts all the flavors with its warm, fragrant aroma.
• Rainbow sprinkles: Add colorful, joyful decoration that makes the cookies truly cosmic.

How to Make Ganache-Stuffed Cosmic Brownie Cookies

Step 1: Prepare the Ganache Filling

Start by finely chopping the semisweet chocolate and placing it in a heatproof bowl. Warm the heavy cream until it’s steaming hot but not boiling, then pour it over the chocolate. Let this mix sit undisturbed for about two minutes so the chocolate softens, then stir gently until the mixture turns smooth and glossy. Pop the ganache into the fridge to chill for around an hour so it firms up and becomes easy to handle later.

Step 2: Preheat the Oven

While your ganache chills, set your oven to 350°F (175°C) and line baking sheets with parchment paper. This simple prep ensures your cookies bake evenly and don’t stick.

Step 3: Mix the Dry Ingredients

In a bowl, whisk together the all-purpose flour, Dutch-process cocoa powder, baking soda, and kosher salt. This blend is going to give your cookies their classic rich brownie taste and perfect texture.

Step 4: Melt the Chocolate

Melt the chopped semisweet chocolate gently over a double boiler or in short bursts in the microwave. Allow it to cool slightly; this glossy addition will help deepen the cookie dough’s chocolate flavor.

Step 5: Cream Butter and Sugars

Using a mixer, beat the unsalted butter with brown sugar and granulated sugar until the mixture turns pale, light, and fluffy. This step is essential for creating cookies with a tender crumb and slightly crispy edges.

Step 6: Add Eggs and Vanilla

One at a time, beat in the eggs, making sure each is fully incorporated before adding the next. Then, stir in the vanilla extract to boost the dough’s aroma and overall taste.

Step 7: Combine Wet and Dry Mixtures

Slowly add the dry ingredients to the wet ingredients, mixing just until they come together. Then fold in the melted chocolate for extra gooey richness throughout the dough.

Step 8: Assemble the Cookies

Now for the fun part: scoop the dough into 2-tablespoon-sized balls. Flatten each ball gently, place a small spoonful of chilled ganache in the center, and carefully fold the dough around it to seal in the chocolatey goodness. Roll it back into a ball and set it on your prepared baking sheet.

Step 9: Add Sprinkles

Press the top of each cookie ball lightly into a bowl of rainbow sprinkles. These sprinkles not only bring a bright burst of color reminiscent of a cosmic celebration but also add a slight crunch that contrasts beautifully with the chewy cookie.

Step 10: Bake and Cool

Bake your cookies for 10-12 minutes until the edges are set but the centers still look slightly soft. Let them cool on the baking sheets for a few minutes to firm up before transferring to a wire rack to cool completely.

Make Ahead and Storage

Storing Leftovers

Place cooled Ganache-Stuffed Cosmic Brownie Cookies in an airtight container at room temperature. They will stay fresh and chewy for up to 4 days, making them a perfect treat to bake ahead for gatherings or snack cravings.

Freezing

If you want to keep these cookies longer, freeze them after baking and cooling by layering them with parchment paper in a freezer-safe container. They freeze beautifully for up to 3 months without losing their rich chocolate flavor or gooey ganache center.

Reheating

To enjoy your frozen Ganache-Stuffed Cosmic Brownie Cookies as if freshly baked, thaw at room temperature and warm them gently in a microwave for 10-15 seconds. The ganache filling will soften and become wonderfully melty again.

FAQs

Can I use milk chocolate instead of semisweet chocolate for the ganache?

Absolutely! Using milk chocolate will create a sweeter, creamier ganache filling. Just keep in mind that it may be less intense in cocoa flavor, but still deliciously smooth inside your cosmic brownie cookies.

Do I have to chill the ganache before stuffing the cookies?

Chilling the ganache is important because it firms up, making it easier to handle and preventing it from oozing out during baking. If you skip this step, the filling might melt too quickly and leak, losing that signature indulgent surprise inside.

Can I make these cookies gluten-free?

Yes! Substitute the all-purpose flour with a gluten-free flour blend designed for baking. Just make sure it includes xanthan gum or another binding agent to keep the cookies’ structure and texture intact.

Why are rainbow sprinkles used in Ganache-Stuffed Cosmic Brownie Cookies?

Rainbow sprinkles add a playful pop of color that makes these cookies feel festive and cosmic, inspired by nostalgic childhood favorites. They also give a slight crunch that contrasts perfectly with the soft, chewy cookie and creamy ganache.

How do I know when the cookies are perfectly baked?

Look for edges that are set and slightly firm while the centers might remain soft and a bit underbaked. This balance ensures chewy cookies with a fudgy texture that pairs beautifully with the ganache center.
