How to Make Fudgy Cosmic Brownie Cookies
Step 1: Preheat Your Oven
First things first—preheat your oven to 350°F (175°C). This ensures your cookies bake evenly and achieve that perfect fudgy texture.
Step 2: Cream the Sugars and Butter
In a large bowl, use an electric mixer on medium-high speed to cream together the softened unsalted butter, light brown sugar, and granulated sugar for about 2 minutes until it’s light and fluffy. This step is key because it incorporates air into the mixture, giving your cookies that lovely soft texture.
Step 3: Mix in Wet Ingredients
Now it’s time to add in your egg, vanilla extract, and light corn syrup. Mix on low speed until everything is well combined. Remember to scrape down the sides of the bowl so no ingredients are left behind—every bit counts!
Step 4: Combine Dry Ingredients
Next, sprinkle in the baking soda and salt before mixing for another 5-10 seconds until just combined. This ensures your cookies will rise nicely during baking while balancing out the sweetness.
Step 5: Add Cocoa Powder and Flour
Gently mix in the dark cocoa powder and all-purpose flour on medium speed until everything is combined. Don’t overmix; we want those fudgy cookies to shine through without becoming tough!
Step 6: Scoop and Shape
Using a cookie scoop (about ¼ cup), scoop out dough and roll it into balls. Then gently flatten each ball into a disc about ½ inch thick. Flattening them helps your cookies spread evenly rather than puffing up too much.
Step 7: Bake!
Pop those beauties into your preheated oven for about 11-12 minutes. Be careful not to overbake; they might look slightly underdone in the center—that’s okay! They’ll continue cooking on the hot pan after you take them out. Allow them to cool completely before adding any decorations.
And there you have it—your very own batch of Fudgy Cosmic Brownie Cookies! Enjoy every single bite!
Pro Tips for Making Fudgy Cosmic Brownie Cookies
Baking these cookies is a delightful experience, and with a few handy tips, you can ensure they turn out perfectly every time!
- Use room temperature ingredients – This helps the butter cream more easily with the sugars, resulting in a light and fluffy base for your cookies.
- Chill the dough – If you have time, refrigerating the dough for about 30 minutes before baking can enhance the texture and flavor of your cookies, making them even fudgier.
- Don’t overbake – Keep an eye on your cookies as they bake; pulling them out while they still look slightly undercooked helps maintain that gooey center we all love.
- Experiment with add-ins – Feel free to mix in some chopped nuts or swap in your favorite chocolate chips for a personal touch that complements the fudgy flavor.
- Store correctly – To keep your cookies fresh and fudgy, store them in an airtight container at room temperature. You can also refrigerate them for an extra chilled treat!
How to Serve Fudgy Cosmic Brownie Cookies
These cookies are a showstopper on their own, but with a few creative serving ideas, you can take them to the next level!
Garnishes
- Rainbow sprinkles – A classic touch that adds a pop of color and fun! Just sprinkle them on top right after baking when the chocolate is still warm.
- Drizzle of melted chocolate – Melt some semi-sweet chocolate chips and drizzle over the cooled cookies for an extra layer of indulgence.
Side Dishes
- Vanilla ice cream – Nothing pairs better with rich brownie cookies than creamy vanilla ice cream. The contrast between warm and cold creates a heavenly dessert experience.
- Fresh berries – A side of strawberries or raspberries adds brightness and acidity that balances out the sweetness of the cookies beautifully.
- Milk or plant-based milk – A tall glass of cold milk (or almond/coconut milk) is perfect for dunking those fudgy delights!
