Essential Ingredients
Here’s what you’ll need to make this delicious dish:
- All-Purpose Flour: Essential for structure; make sure it’s fresh for the best texture.
- Cocoa Powder: Use unsweetened cocoa powder for that deep chocolate flavor that everyone craves.
- Baking Powder: This helps the cookies rise beautifully and maintain their chewy texture.
- Salt: A pinch enhances all the flavors; don’t skip it even if you’re watching your sodium intake.
- Unsalted Butter: Use softened butter for the right creaminess; it leads to perfectly chewy cookies.
- Brown Sugar: This adds moisture and depth of flavor—light or dark works well here!
- Granulated Sugar: Balances out the brown sugar’s richness for sweet perfection.

Let’s Make it Together
Preheat Your Oven and Prepare Baking Sheets: Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper—they’ll keep your cookies from sticking like that ex who won’t leave you alone.
Mix Dry Ingredients: In a bowl, whisk together flour, cocoa powder, baking powder, and salt until well combined. This step ensures even distribution of those dry ingredients so every cookie is equally delicious.
Cream Butter and Sugars: In another bowl, cream together softened butter, brown sugar, and granulated sugar until fluffy. You want this mixture light and airy—like your mood when you realize it’s Friday
Add Eggs and Vanilla: Beat in the eggs one at a time followed by the vanilla extract until everything is well combined. The batter should look smooth and luscious—a sign that good things are coming.
Add Dry Ingredients: Gradually mix in the dry ingredients until just combined. Be careful not to overmix; we want our cookies tender—not tough like Monday morning meetings.
Add Chocolate Chips and Sprinkles: Fold in chocolate chips and rainbow sprinkles gently using a spatula. Watch as they swirl into your batter like colorful comets racing across a midnight sky.
Scoop and Bake: Use a tablespoon to scoop dough onto prepared baking sheets spaced evenly apart. Bake for 10-12 minutes until edges are set but centers remain slightly soft—trust me; they’ll firm up as they cool
Enjoying these Cosmic Brownie Cookies is not just about satisfying cravings but also reliving cherished memories while creating new ones with each batch you bake
