Ingredients You’ll Need

This Cosmic Brownie Cookies Recipe comes together with surprisingly simple ingredients, each chosen to build the perfect balance of rich chocolate, chewy texture, and that irresistible burst of candy crunch. Keeping these essentials on hand makes it easy to whip up a batch whenever the craving strikes.

2 cups plus 2 Tbsp flour (270 g): The foundation for the cookie’s soft structure.
½ cup plus 2 Tbsp dutch processed cocoa powder (67 g): Adds deep, intense chocolate flavor and that signature dark color.
½ tsp espresso powder (optional but strongly suggested): Boosts the chocolate notes and enriches the overall flavor.
½ tsp baking soda: Helps achieve that slight rise and tender crumb.
½ tsp baking powder: Works alongside baking soda to create the perfect cookie texture.
½ tsp sea salt: Balances sweetness and enhances the chocolate’s richness; reduce if using salted butter.
1 cup salted butter (227 g, room temperature): Adds moisture, flavor, and a tender crumb.
1 cup white sugar (200 g): Sweetens and contributes to the cookie’s structure.
½ cup light brown sugar (110 g): Provides moisture, chewiness, and a subtle caramel note.
2 large eggs (room temperature): Bind the ingredients and add richness.
1 ½ tsp vanilla extract: Brings warmth and complements the chocolate perfectly.
4 oz dark or semi-sweet chocolate: Creates a luscious ganache topping for that extra layer of decadence.
⅓ cup heavy whipping cream: Mixed with chocolate for a silky, smooth ganache.
Mini rainbow candy coated chips for topping: Adds a playful pop of color and crunch that makes these cookies truly cosmic.

How to Make Cosmic Brownie Cookies Recipe

Step 1: Prep Your Oven and Dry Ingredients

Start by preheating your oven to 350°F to get it ready for baking these cosmic delights. While the oven warms, whisk together all your dry ingredients—flour, espresso powder, cocoa, salt, baking soda, and baking powder—in a medium bowl. This step ensures everything is evenly distributed so every cookie gets consistent flavor and texture.

Step 2: Cream Butter and Sugars

In a separate bowl or your stand mixer, beat the room temperature butter with both white and brown sugars until the mixture is light and fluffy. This will take about 3 to 4 minutes and is key to achieving that tender crumb and slight chewiness in your cookies. Then, add eggs and vanilla extract, beating just until incorporated.

Step 3: Combine Wet and Dry Ingredients

Add the flour mixture in thirds to your butter and sugar mixture, beating gently after each addition. Be careful not to overmix here—the goal is just to blend everything together so your cookie stays tender, not tough.

Step 4: Shape and Bake the Cookies

Using a 1 ½ tablespoon cookie scoop, roll the dough into balls and place them on a parchment-lined baking sheet spaced about 2 inches apart to give them room to spread. Bake for 7 to 10 minutes until the edges look set and the tops puff up and feel soft to the touch. About eight minutes is the sweet spot for perfectly chewy centers and slightly crisp edges.

Step 5: Shape the Baked Cookies (Optional but Stunning)

Right out of the oven, you can gently press a biscuit or cookie cutter around each cookie to give them uniform, pretty circles. This step is optional but adds a polished look that makes the cookies feel extra special. Let them cool a few minutes before moving to a wire rack.

Step 6: Make the Luxurious Ganache

Chop your dark chocolate into fine pieces and place in a small bowl. Heat the heavy cream in short bursts in the microwave until it’s hot but not boiling. Pour the cream over the chocolate and let it sit for a few minutes, then stir until smooth and glossy. If some chocolate chunks remain, a few more seconds in the microwave will finish melting it perfectly.

Step 7: Finish with Ganache and Candy Topping

Spoon about three-quarters of a teaspoon of the ganache onto each cooled cookie, spreading gently to cover the tops. Immediately sprinkle mini rainbow candy-coated chips on top to add a cosmic burst of color and crackle with every bite. Let them set for about an hour or dive in sooner if you can’t wait!

How to Serve Cosmic Brownie Cookies Recipe

Garnishes

These cookies shine on their own, but a sprinkle of flaky sea salt on top of the ganache just before it sets creates an incredible flavor contrast. If you want to get fancy, dusting with a light shimmer of edible glitter brings home the cosmic theme beautifully.

Side Dishes

Pair your Cosmic Brownie Cookies with a creamy glass of cold milk or a scoop of vanilla ice cream for an indulgent experience. For a grown-up twist, a cup of rich espresso or a mocha latte complements the chocolate depth beautifully.

Creative Ways to Present

Arrange these cookies on a star-shaped platter or scatter edible star sprinkles on your serving tray for a fun theme party vibe. Stack them with layers of parchment paper for gifting, tied with a bright ribbon to match the rainbow chips. These little touches make serving Cosmic Brownie Cookies even more joyful.

Make Ahead and Storage

Storing Leftovers

Once cooled, store your cookies in an airtight container at room temperature. They stay soft and chewy for up to five days—perfect for enjoying over the week or sharing at gatherings.

Freezing

Cosmic Brownie Cookies freeze wonderfully. Just wrap them individually in plastic wrap, place them in a freezer-safe container or bag, and freeze for up to three months. Thaw at room temperature when ready to enjoy.

Reheating

If you want to bring back that fresh-from-the-oven warmth, pop a cookie or two in the microwave for about 10 seconds. The ganache may get slightly melty again, which only adds to the indulgence. Enjoy warm for a hug-in-a-cookie experience.

FAQs

Can I make these cookies without espresso powder?

Absolutely! The espresso powder is optional but highly recommended because it enhances the chocolate flavor without adding a coffee taste. If you don’t have it, just skip it—the cookies will still be deliciously chocolatey.

What’s the best type of chocolate for the ganache?

Using high-quality dark or semi-sweet baking chocolate is best for a smooth, rich ganache. Chocolate chips work in a pinch, but baking chocolate melts more evenly and provides superior flavor.

How do I ensure my cookies stay chewy?

The balance of brown sugar and white sugar helps keep them chewy, as does baking for the right amount of time—around eight minutes is perfect. Also, be careful not to overmix the dough, which can make cookies tough.

Can I substitute mini candy-coated chips with something else?

Yes! Mini rainbow candy-coated chips give a classic cosmic look, but you can also use sprinkles, mini M&Ms, or even chopped colorful dried fruit for a varied texture and visual appeal.

Is it necessary to use a cookie cutter after baking?

Not at all. The cookie cutter step is purely aesthetic to give uniform rounds, but the cookies taste just as fabulous without it. It’s a nice touch if you want a polished presentation.
