How to Make Better than CRUMBL Cosmic Brownie Cookies Recipe
Step 1: Prep Your Baking Station
Start by preheating your oven to 350°F and lining a large baking sheet with parchment paper or a silicone mat. This little prep step ensures your cookies bake evenly without sticking, making clean-up a breeze too.
Step 2: Mix Your Dry Ingredients
In a small bowl, whisk together the flour, cocoa powder, baking powder, and salt. Separating dry ingredients like this helps distribute everything evenly, so your cookies rise just right with a smooth chocolate flavor in every bite.
Step 3: Melt Butter and Chocolate
Gently melt the butter and 8 ounces of semi-sweet chocolate chips in a medium saucepan over medium-low heat. Stir continuously until silky and smooth, then set aside to cool slightly. This rich chocolate foundation is the secret behind these cookies’ fudgy texture.
Step 4: Whip Eggs and Sugars
In a stand or hand mixer, beat the eggs, vanilla, brown sugar, and granulated sugar on medium-high speed for about 3 to 5 minutes. You want the mixture to become light, airy, and almost double in volume—this step is key to getting that perfect cookie lift without being cakey.
Step 5: Combine Wet and Dry Mixtures
Slowly fold the warm chocolate-butter mixture into the whipped egg mixture, mixing gently. Next, add the dry ingredients and fold just until combined. Be careful to avoid over-mixing here; you want to keep all that lovely airiness intact while ensuring the flour is fully incorporated.
Step 6: Scoop and Bake
Using a large cookie scoop, portion the dough into 10 equal balls onto your prepared baking sheet. Space them about 2 inches apart to give the cookies space to spread a bit. Bake for 12 minutes or until the edges look set but the centers remain soft.
Step 7: Shape and Cool
While still warm, use a large cookie cutter slightly wider than the cookies to gently swoosh around the edges, forming perfect round, thick cosmic brownie cookies. Let them sit on the baking sheet for 10 minutes to finish setting before transferring to a rack to cool completely.

Side Dishes

Make Ahead and Storage
Storing Leftovers
Store any leftover cookies in an airtight container at room temperature, and they’ll stay fresh and chewy for up to 4 days. Keeping them sealed is the key to preserving those fudgy, delicious qualities that make this recipe stand out.
Freezing
These cookies freeze wonderfully. Pop cooled cookies in a freezer-safe bag or container, layering with parchment paper to prevent sticking. They can last up to 3 months frozen, making it easy to enjoy Better than CRUMBL Cosmic Brownie Cookies Recipe anytime you want a chocolatey pick-me-up.
Reheating
For a fresh-baked taste, gently warm thawed cookies in the microwave for 15 to 20 seconds or in a low-temperature oven for a few minutes. This softens them up and brings back that amazing gooey texture you crave, as if they just came out of the oven.
FAQs
Can I substitute the all-purpose flour with gluten-free flour?
Yes, you can use a gluten-free flour blend that measures cup-for-cup like all-purpose flour. Just make sure it includes xanthan gum or another binder to keep the cookies’ texture intact, as this recipe relies on the flour’s structure for that perfect fudgy chew.
Why do I need to whip the eggs and sugars so long?
Whipping the eggs with the sugars incorporates air into the batter, which helps lighten the dense chocolate base without making it cakey. It’s a crucial step for achieving a cookie that’s rich but with a tender crumb and a bit of bounce.
Can I use milk chocolate instead of semi-sweet chocolate chips?
You can, but keep in mind that milk chocolate is sweeter and less intense, so your cookies will be sweeter and less rich. Semi-sweet adds that perfect balance and depth, which is why it’s preferred for this recipe.
What’s the best way to get those perfectly round, thick cookie shapes?
The trick is using a large cookie cutter right after baking, while the cookies are still warm and soft. Gently swoosh it around each cookie to mold the shape. This step keeps the cookies looking uniform and gives them that signature thick, cosmic look.
Can I double the recipe for a larger batch?
Absolutely! Just double all the ingredients and bake on multiple trays if needed. Keep consistent spacing on your baking sheets to allow even heat circulation. Also, watch baking time closely, as larger batches might need a minute or two more.

- 1/2 cup granulated sugar
- 1 tsp vanilla extract
- 1/4 cup heavy cream
Toppings
- 6 oz semi-sweet chocolate chips (good quality)
- Rainbow chocolate candies
Instructions
- Preheat the oven and prepare baking sheet: Start by preheating the oven to 350°F (175°C). Line a large baking sheet with parchment paper or a silicone baking mat to prevent the cookies from sticking.
- Mix dry ingredients: In a small bowl, whisk together the all-purpose flour, cocoa powder, baking powder, and a pinch of salt. Set this mixture aside for later.
- Melt butter and chocolate chips: In a medium saucepan over medium-low heat, melt the butter alongside 8 oz of semi-sweet chocolate chips. Stir continuously until fully melted and combined. Remove from heat and let it cool slightly.
- Beat eggs and sugars: Using a stand or hand mixer, whisk the room temperature eggs, vanilla extract, brown sugar, and granulated sugar on medium-high speed for 3-5 minutes until the mixture becomes light, airy, and roughly doubles in volume.
- Combine wet and dry mixtures: Slowly pour the melted chocolate and butter mixture into the egg mixture and gently fold to combine. Then gradually add the dry ingredient mixture, folding gently with a rubber spatula just until well incorporated and no visible flour remains. Avoid overmixing to keep the batter tender.
- Scoop and bake: Using a large cookie scoop, drop 10 evenly sized cookie dough balls onto the prepared baking sheet, leaving about 2 inches of space between each. Bake in the preheated oven for 12 minutes or until the edges are set.
- Shape cookies and cool: After baking, if needed, use a large cookie cutter slightly wider than your cookies to gently press around the edges, creating a perfect round shape and thick appearance. Let the cookies cool on the baking sheet for 10 minutes before transferring to a wire rack to cool completely.
- Garnish with toppings: While the cookies are still warm, press rainbow chocolate candies and the remaining 6 oz of semi-sweet chocolate chips on top. If desired, drizzle with warmed heavy cream to create a glossy finish and enhance moisture.

- Do not overmix when combining the dry and wet ingredients to keep the cookies fudgy and tender.
