Ingredients
For the Cookie Dough
- ½ cup unsalted butter (softened)
- ½ cup light brown sugar
- ¼ cup granulated sugar
- 1 large egg
- 1 teaspoon vanilla extract
- 2 tablespoons light corn syrup
- ¼ teaspoon baking soda

How to Make Fudgy Cosmic Brownie Cookies (TikTok Viral!)
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your cookies bake evenly.
Step 2: Cream the Butter and Sugars
In a large bowl, use an electric mixer on medium-high speed to cream together:
1. ½ cup unsalted butter (softened)
2. ½ cup light brown sugar
3. ¼ cup granulated sugar
Mix for about 2 minutes until the mixture is light and fluffy.
Step 3: Add Wet Ingredients
Add in:
1. 1 large egg
2. 1 teaspoon vanilla extract
3. 2 tablespoons light corn syrup
Mix on low speed until fully combined. Scrape down the sides of the bowl to ensure everything blends well.
Step 4: Combine Dry Ingredients
Add:
1. ¼ teaspoon baking soda
2. ¼ teaspoon salt
Mix for another 5–10 seconds until incorporated.
Step 5: Incorporate Cocoa and Flour
Finally, add:
1. ½ cup dark cocoa powder
2. 1 ¼ cups all-purpose flour
Mix on medium speed until no dry flour remains visible.
Step 6: Shape the Cookies
Scoop dough into ¼ cup sized scoops using a cookie scoop. Roll into balls then gently flatten each ball into a disc approximately ½ inch thick to promote even spreading while baking.
Step 7: Bake the Cookies
Place the cookies on a prepared baking sheet lined with parchment paper. Bake at 350°F for about 11–12 minutes. Be cautious not to overbake; centers may appear slightly wet but will firm up as they cool on the pan.
Allow cookies to cool completely before decorating with heavy cream drizzle and rainbow chip sprinkles.

Common Mistakes to Avoid
Baking Fudgy Cosmic Brownie Cookies can be tricky, but avoiding common mistakes will ensure your cookies turn out perfectly. Here are some pitfalls to watch out for:
-
Ignoring ingredient temperature: Using cold butter or eggs can affect the texture. Make sure to soften the butter and bring the egg to room temperature before mixing.
-
Overmixing the dough: Mixing too much can lead to tough cookies. Aim for just combined ingredients, especially after adding flour.

Not measuring flour correctly: Too much flour will make the cookies dry. Use a spoon to fluff the flour, then scoop it into your measuring cup without packing it down.
-
Skipping chilling time: Allowing the dough to chill enhances flavor and texture. If you’re short on time, even a quick 10-15 minute chill helps.
-
Overbaking the cookies: Keep an eye on your cookies; they should look slightly underbaked in the center when you remove them from the oven.
