There are a million reasons to fall in love with these Cosmic Brownie Cookies, but let me give you my top few. First and foremost, the flavor is just insane!

How do I make Cosmic Brownie Cookies?

Quick Overview

Making these Cosmic Brownie Cookies is simpler than you might think! We start by creating a rich, fudgy cookie dough. Then, you’ll shape the cookies, bake them to perfection, and top them with a glossy chocolate glaze and rainbow sprinkles. The whole process is quick and easy, and the result is a batch of decadent, irresistible cookies. It’s really the perfect recipe for when you want something sweet and satisfying without spending hours in the kitchen.

Ingredients

For the Main Batter:
* 1 cup (2 sticks) unsalted butter, softened: Make sure your butter is truly softened, not melted. This helps create a wonderfully soft cookie.
* 1 cup granulated sugar: For sweetness and structure.
* 1 cup packed light brown sugar: This adds moisture and chewiness, giving the cookies that classic brownie texture.
* 2 large eggs: These bind the ingredients together and add richness. I always use large, free-range eggs for the best flavor.
* 1 teaspoon Vanilla Extract: A must for enhancing the chocolate flavor. Don’t skimp on quality here; a good vanilla extract makes a huge difference.
* 1 cup all-purpose flour: Provides the structure for the cookies.
* ¾ cup unsweetened cocoa powder: This is where the deep, dark chocolate flavor comes from. I prefer Dutch-processed cocoa powder for its smoother taste.
* ½ teaspoon baking soda: Helps the cookies rise and gives them a slightly chewy texture.
* ¼ teaspoon salt: Balances the sweetness and enhances the other flavors.
* 1 cup semi-sweet chocolate chips: Adds extra chocolate chunks for a truly decadent treat.

For the Glaze:
* 4 tablespoons (½ stick) unsalted butter: Adds richness and shine to the glaze.
* 2 cups powdered sugar: This creates a smooth, sweet glaze.
* ¼ cup unsweetened cocoa powder: For a deeper chocolate flavor in the glaze.
* 3-5 tablespoons milk: To achieve the perfect glaze consistency. Start with 3 tablespoons and add more gradually until you reach your desired thickness.
* 1 teaspoon vanilla extract: Enhances the glaze flavor.

For the Sprinkles: What is
* Rainbow sprinkles: The iconic topping that makes these cookies look just like Cosmic Brownies. Don’t be shy – pile them on!

How do I follow step

Step 1: Preheat & Prep Pan

Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper. This prevents the cookies from sticking and makes cleanup a breeze. I always find that preheating for at least 15 minutes helps ensure even baking.

Step 2: Mix Dry Ingredients

In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt. Set aside. Make sure everything is well combined. How do I distribute baking soda and cocoa powder evenly across the dough? What is the key for the right texture and flavor?

Step 3: Mix Wet Ingredients

In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light. Set aside. Beat the eggs one at a time, then stir in the vanilla extract. The mixture should be smooth and creamy. This step is crucial for incorporating air into the dough, which helps the cookies rise properly. I usually use a stand mixer for this, but hand mixer works just as well. How do you not overwhip?

Step 4: Combine

Add dry ingredients to wet ingredients, mixing until just combined. Be careful not to overmix. Overmixing can develop the gluten in the flour, resulting in tough cookies. What is the best way to add chocolate chips? Just gently stir them in until they’re evenly distributed throughout the dough.

Step 5: Prepare Filling

This step doesn’t have a separate filling like some cookies. The brownie-like batter is the filling! The chocolate chips add little pockets of melty goodness.

Step 6: Layer & Swirl

Since these aren’t swirl cookies, just roll rounded tablespoons of dough and place them 2 inches apart on the prepared baking sheet. I usually use a cookie scoop to ensure that all the cookies are the same size, so they bake evenly. You can flatten them slightly with your fingers if you like, but they will spread out a bit during baking.

Step 7: Bake

Bake for 9-11 minutes, or until the edges are set and the centers are still slightly soft. As cookies cool, they will continue to set up. Keep a close eye on them, as baking times can vary depending on your oven. I always find that pulling them out just before they look completely done results in the chewiest.

Step 8: Cool & Glaze

Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely. While the cookies are cooling, prepare the glaze. In a medium saucepan, melt the butter over low heat. Remove from heat and whisk in the powdered sugar and cocoa powder until smooth. Gradually add the milk, whisking until you reach your desired consistency. Stir in the vanilla extract. Once the cookies are completely cool, spread the glaze evenly over the tops of the cookies. Immediately sprinkle with rainbow sprinkles. The glaze will set quickly, so it’s important to add the sprinkles right away.

Step 9: Slice & Serve

What are cookies made of? Honestly, I usually grab one straight off the cooling rack (or two!).

As Dessert: These cookies are the perfect after-dinner treat. Serve them with a scoop of vanilla Ice Cream or a dollop of whipped cream. A drizzle of chocolate sauce or caramel sauce adds an extra touch of indulgence. My family always loves them with a side of hot chocolate on a cold night.

For Cozy Snacks: Curl up on the couch with a plate of these cookies and a warm mug of milk or tea. They’re also great for movie nights or game nights with friends and family. I sometimes sneak one in when I need a little boost in the afternoon – they’re a total lifesaver!

What are some tips and tricks to make a Cosmic Brownie?

Butter Softening:Make sure your butter is properly softened before creaming it with the sugars. If your finger is soft enough to touch it, it should not be melted. How do I make a fluffy dough?

Mixing Advice:Be careful not to overmix the dough. Can overmixing cause gluten in the flour, resulting in tough cookies. Mix dry ingredients into wet ingredients until just combined. I always stop mixing when I no longer see streaks of flour.

Sprinkle Application: Add the rainbow sprinkles immediately after glazing the cookies. The glaze sets quickly, so if you wait too long, the sprinkles won’t stick.

Ingredient Swaps:If you don’t have semi-sweet chocolate chips, you can use dark chocolate or milk chocolate. Can you add other mix-ins, like chopped nuts or dried fruit? I’ve tried adding chopped walnuts before, and they were delicious! Just be sure to adjust the amount of chocolate chips accordingly.

Baking Tips:What are the best ways to keep a close eye on your cookies while baking? I always find that pulling them out just before they look completely done results in the chewiest. They will continue to set up as they cool.

Glaze Variations:For a richer glaze, use melted chocolate instead of cocoa powder. If you like a sweet glaze, you can also add salt to it. I sometimes add coffee liqueur to the glaze for a mocha flavor – it’s amazing!

Storing and Reheating Tips

Here’s how to store your Cosmic Brownie Cookies to keep them fresh and delicious:

Room Temperature: Store the cookies in an airtight container at room temperature for up to 3 days. Make sure they are completely cool before storing them. I usually put a piece of parchment paper between the layers to prevent them from sticking together.

Refrigerator Storage: For longer storage, you can store the cookies in an airtight container in the refrigerator for up to a week. The cookies may become a bit firm in the fridge, so let them come to room temperature before serving.

Freezer Instructions: To freeze the cookies, wrap them individually in plastic wrap and then place them in a freezer-safe bag or container. They can be frozen for up to 2 months. Let them thaw at room temperature before serving.

Glaze Timing Advice: If you plan to freeze the cookies, it’s best to glaze them after thawing. The glaze can become sticky or crack during freezing. If you’ve already glazed the cookies, they’re still safe to freeze, but the appearance may be slightly altered.
