Essential Ingredients for Crumbl Cookies Cosmic Brownie Recipe
Creating the perfect homemade cosmic brownie cookies requires gathering the right components before you start mixing. The success of this copycat Crumbl cosmic brownie relies heavily on the quality of your ingredients, particularly the cocoa and chocolate used for the base and frosting. Below, you will find a detailed breakdown of everything you need to make these fudge-filled brownie cookies.Main Ingredients
- 1 cup unsalted butter (softened) – Creates a rich, tender base and helps the cookies spread perfectly.
- 1 cup light brown sugar – Adds moisture and a deep, caramel-like sweetness.
- 1/2 cup white sugar – Provides crispness to the edges of the cookie.
- 2 large eggs – Acts as the binder and adds structure to the dough.
- 1 tsp vanilla extract – Enhances the overall flavor profile.
- 2 1/2 cups all-purpose flour – The main structure for the cookies.
- 2/3 cup unsweetened cocoa powder – Delivers the intense chocolate flavor.
- 1 tsp baking soda – Helps the cookies rise slightly for a soft texture.
- 1/2 tsp salt – Balances the sweetness and highlights the chocolate notes.
- 1 cup semi-sweet chocolate chips – The base for the rich ganache frosting.
- 3/4 cup heavy whipping cream – Creates the silky, pourable consistency of the ganache.
- 1/2 cup powdered sugar – Sweetens and stabilizes the frosting.
- 1/4 cup unsalted butter (softened) – Adds creaminess to the frosting.
- 1/2 cup mini M&Ms or colorful candy pieces – Provides the signature crunch and colorful topping.
Special Dietary Options
Adapting this crumbl cosmic brownie recipe to fit specific dietary requirements is simple. Here are a few swaps you can make: Vegan: To make these cookies plant-based, replace the butter with a high-quality vegan butter stick and use flax eggs (1 tablespoon ground flaxseed meal mixed with 3 tablespoons water per egg) instead of chicken eggs. For the ganache, use full-fat coconut milk or a vegan heavy cream alternative and dairy-free chocolate chips. Gluten-Free: Substitute the all-purpose flour with a 1-to-1 gluten-free baking blend that contains xanthan gum. This ensures the cookies maintain their chewy texture without crumbling. Ensure your oats and other additives are certified gluten-free. Low-Calorie: While dessert is meant to be indulgent, you can reduce the calorie count by using a sugar substitute like erythritol or stevia in the dough and frosting. Additionally, you can use applesauce or Greek yogurt to replace half of the butter in the cookie base for a lighter version that still tastes great.Check out our guide on Baking Basics for more tips on how to measure flour and cocoa correctly to ensure your cookies turn out perfect every time.
How to Prepare the Perfect Crumbl Cookies Cosmic Brownie Recipe: Step-by-Step Guide
Making these delicious treats is a rewarding process. By following these clear steps, you will achieve a bakery-quality result that rivals the famous store-bought version. This easy cosmic brownie recipe breaks down the method into manageable parts, focusing on technique to ensure the perfect texture.Preparing the Cookie Dough
First Step: Start by preparing your mise en place. Ensure your butter is softened to room temperature so it creams easily with the sugars. Preheat your oven to 350°F and line two large baking sheets with parchment paper. This prevents sticking and makes cleanup effortless. Second Step: In a large bowl, cream together 1 cup of softened butter, 1 cup of light brown sugar, and 1/2 cup of granulated sugar. Beat on high speed for about 3 minutes. You want the mixture to be pale and fluffy, which incorporates air into the dough for a lighter texture. If you are watching your sugar intake, this is the stage where you might mix in your sugar substitutes. Third Step: Add the 2 large eggs and 1 teaspoon of vanilla extract to the butter mixture. Beat again until the eggs are fully incorporated and the mixture looks glossy. Scrape down the sides of the bowl to ensure everything is evenly mixed. This step is crucial for emulsifying the ingredients. Fourth Step: In a separate medium bowl, whisk together the dry ingredients: 2 1/2 cups of all-purpose flour, 2/3 cup of unsweetened cocoa powder, 1 teaspoon of baking soda, and 1/2 teaspoon of salt. Whisking these together ensures the leavening agents are evenly distributed throughout the flour, preventing pockets of bitter baking soda in your finished cookies. Fifth Step: Gradually add the dry flour mixture to the wet ingredients. Mix on low speed just until the flour streaks disappear. Be careful not to overmix, as this can develop the gluten in the flour and make the cookies tough rather than chewy. The dough will be thick and dark.Chilling and Baking
Sixth Step: Cover the bowl and place the dough in the refrigerator to chill for at least 30 minutes. This step is vital because chilled dough produces thicker cookies with a richer flavor. It prevents the cookies from spreading too flat in the oven, ensuring they remain soft and fudgy in the center. Seventh Step: Once chilled, scoop the dough using a 1/4 cup measuring scoop to form large balls. Place them on the prepared baking sheets, leaving about 2 inches of space between each ball to allow for spreading. For the authentic Crumbl experience, do not flatten the balls; let them spread naturally. Eighth Step: Bake the cookies in the preheated oven at 350°F for 10 to 12 minutes. You will know they are done when the edges look set and matte, but the centers still look slightly soft and underbaked. Remove them from the oven and let them cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely. They will finish cooking on the hot pan.Making the Ganache Frosting
Ninth Step: While the cookies are cooling, prepare the frosting. In a microwave-safe bowl, heat 3/4 cup of heavy whipping cream until it is simmering, which should take about 1 minute. Pour the hot cream over 1 cup of semi-sweet chocolate chips. Let it sit for 2 minutes to soften the chocolate without stirring. Tenth Step: After 2 minutes, stir the mixture vigorously until the chocolate is completely melted and the ganache is smooth and glossy. Whisk in 1/2 cup of powdered sugar and 1/4 cup of softened butter until the frosting is creamy and spreadable. If the consistency is too thick, add a teaspoon of cream; if it is too thin, let it chill in the fridge for 5 minutes. Final Step: Once the cookies are completely cool, spread about 2 to 3 tablespoons of the ganache onto each cookie. Use an offset spatula to create a smooth, even layer. Immediately sprinkle the mini M&Ms or colorful candy pieces on top before the frosting sets. Let the frosting firm up for about 15 minutes before serving.

One of the joys of baking at home is the ability to adjust recipes to fit your specific health needs or pantry inventory. This cosmic brownie cookies recipe is very forgiving, allowing for several swaps that keep the delicious taste intact while catering to different preferences.Protein and Main Component Alternatives
If you are looking to increase the protein content of these cookies, consider modifying the flour base. You can replace up to half of the all-purpose flour with almond flour or a protein powder designed for baking. This adds a nutty flavor and a protein boost, making the cookies a more substantial snack. Keep in mind that almond flour creates a softer, more caky texture, so you may want to reduce the baking time by a minute or two. For the main fat source, coconut oil makes an excellent substitute for butter if you prefer a dairy-free or plant-based fat. Use refined coconut oil to avoid a coconut flavor in the final product. This swap maintains the moisture level and crisp edges of the cookie. Additionally, using black beans in place of some flour is a popular secret for adding fiber and protein to brownies, though it will slightly alter the classic texture of this copycat crumbl recipe.Vegetable, Sauce, and Seasoning Modifications
While traditional brownie cookies do not typically contain vegetables, you can incorporate pureed vegetables like avocado or zucchini to increase moisture and nutrient density. Mashed avocado can replace half of the butter in the frosting and dough, offering healthy fats and a velvety texture. Similarly, finely grated zucchini can be added to the dough for moisture without altering the chocolate flavor significantly, provided you squeeze out excess water first. For the sauce element, which is essentially the ganache, you can experiment with different flavors. A splash of raspberry extract or a teaspoon of instant espresso powder mixed into the hot cream before adding the chocolate can transform the frosting into a mocha or chocolate-raspberry delight. These seasoning modifications allow you to create a gourmet twist on the standard chocolate fudge taste.If you love experimenting with flavors, you might enjoy reading our article on Unique Flavor Combinations for Baking to find more inspiration for your kitchen creations.
Mastering Crumbl Cookies Cosmic Brownie Recipe: Advanced Tips and Variations
Once you have mastered the basic recipe, there are several advanced techniques and creative variations you can try to take your homemade cosmic brownie cookies to the next level. These tips will help you achieve professional results and impress your friends and family.Pro Cooking Techniques
For an even richer chocolate experience, try blooming your cocoa powder. Whisk the cocoa powder with a small amount of hot water or coffee before adding it to the dry ingredients. This releases the fat-soluble flavor compounds in the cocoa, resulting in a more intense chocolate taste. Another pro tip is to weigh your ingredients using a kitchen scale rather than using measuring cups. Precision is key in baking, and weight ensures you get the exact same result every time you bake. When creaming your butter and sugar, do not rush the process. The longer you cream them, the more air is incorporated, leading to a lighter, fluffier cookie. However, if you prefer a denser, fudgier texture that mimics a traditional brownie even more closely, reduce the creaming time to just one minute.Flavor Variations
While the classic version is a hit on its own, adding mix-ins can create exciting new profiles. Consider stirring in 1/2 cup of chopped walnuts or pecans to the dough for a crunchy texture that pairs beautifully with the soft chocolate. You could also add white chocolate chips to the dough for a cookies-and-cream style contrast against the dark cocoa base. For the topping, swap the mini M&Ms for crushed pretzels, potato chips, or sea salt flakes. This combination of sweet and salty is a modern twist that gourmet bakeries often feature. Peanut butter lovers can swirl a tablespoon of warmed peanut butter into the ganache before spreading it on the cookies for a Reese’s-like flavor.Presentation and Make-Ahead Options
Presentation matters, especially if you are serving these at a party. Use a piping bag fitted with a large star tip to apply the ganache instead of spreading it with a knife. This creates a decorative swirl that looks elegant and bakery-style. You can also use a variety of colorful sprinkles to match holiday themes or birthday parties. For busy schedules, this recipe is excellent for meal prep. You can make the dough balls and freeze them raw. Simply place the scooped dough on a baking sheet, freeze until solid, and then transfer them to a freezer bag. When you are ready to bake, you can put the frozen dough balls directly onto the baking sheet; just add an extra minute or two to the baking time. This ensures you always have fresh, warm cookies on demand.How to Store Crumbl Cookies Cosmic Brownie Recipe: Best Practices
To keep your cookies tasting fresh and delicious, proper storage is essential. Because these cookies feature a ganache frosting and candy toppings, they require a bit more care than standard drop cookies. Follow these guidelines to maintain the best texture and flavor for as long as possible.Refrigeration
If you plan to eat the cookies within a few days, storing them in an airtight container at room temperature is perfectly fine. They will stay soft and chewy for 4 to 5 days. However, if your kitchen is particularly warm or you prefer the ganache to be firmer, you can store the container in the refrigerator. Just be aware that refrigeration can sometimes cause the cookie base to dry out slightly. To mitigate this, place a slice of white bread in the container with the cookies. The bread releases moisture, keeping the cookies soft.Freezing
Freezing is an excellent option for long-term storage. It is best to freeze the cookies before frosting them. Wrap the unfrosted cookies individually in plastic wrap and place them in a freezer-safe bag. They can last for up to 3 months in the freezer. When you are ready to eat them, thaw the cookies at room temperature for about an hour, then prepare the fresh frosting and toppings. This ensures the ganache remains glossy and the candies stay crunchy. If you must freeze frosted cookies, flash freeze them first by placing them on a tray in the freezer for 2 hours, then wrap them individually. Consume frozen frosted cookies within 1 month for the best quality.Reheating and Meal Prep
There is nothing quite like a warm cookie. To reheat refrigerated or thawed cookies, place them in the microwave for 10 to 15 seconds. This warms the chocolate center and softens the dough. Avoid overheating, or the ganache will melt completely and become messy. If you prefer a slightly crisp edge, you can reheat them in a 300°F oven for 5 minutes. For meal prep, consider making a double batch of the dough on the weekend. Scoop the dough into balls and store them in the fridge for up to 3 days or freeze them as described above. This allows you to bake fresh cookies throughout the week with minimal effort. Having dough ready to go makes it easy to satisfy a sweet tooth spontaneously.
