Recipe preparation

Essential Ingredients

Here’s what you’ll need to make this delicious dish:

All-Purpose Flour: Choose unbleached flour for better texture; it gives the cookies a lovely chewiness.
Cocoa Powder: Unsweetened cocoa powder provides deep chocolate flavor; select high-quality brands for best results.
Baking Powder: Fresh baking powder ensures your cookies rise beautifully; check expiration dates before use.
Salt: A pinch of salt enhances the sweetness; don’t skip this step!
Unsalted Butter: Use softened butter for easy mixing; it creates that rich flavor we love in cookies.
Brown Sugar: Light brown sugar adds moisture and depth; feel free to use dark brown sugar for extra richness.
Granulated Sugar: Regular sugar balances the flavors; it’s essential for that classic cookie sweetness.
Eggs: One large egg binds everything together; make sure it’s at room temperature for better mixing.
Vanilla Extract: Pure vanilla extract infuses aroma and flavor; skip imitation vanilla if you can!
Chocolate Chips: Semi-sweet chocolate chips provide gooey pockets of melted chocolate; milk or dark chips are great alternatives.
Rainbow Sprinkles: These add color and fun! Use any sprinkles you like for decoration.

The full ingredients list, including measurements, is provided in the recipe card directly below.

Let’s Make it Together

Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper so those cosmic goodies don’t stick like they’re playing hide-and-seek.

Melt the Butter and Mix Sugars: In a large bowl, melt the unsalted butter in the microwave until smooth. Stir in brown and granulated sugars until well combined—this will create that delightful caramel-like base.

Add Eggs and Vanilla: Beat in the egg and vanilla extract until thoroughly mixed—this step helps bind your cosmic cookie creation together.

Sift Dry Ingredients: In another bowl, sift together all-purpose flour, cocoa powder, baking powder, and salt. Sifting helps aerate the dry ingredients for fluffier cookies.

Combine Wet and Dry Ingredients: Gradually fold dry ingredients into the wet mixture using a spatula; be gentle here so you don’t deflate all that cosmic magic.

Add Chocolate Chips: Toss in those semi-sweet chocolate chips like they’re confetti at a cosmic party—mix until evenly distributed throughout your dough.

Scoop and Bake: Scoop tablespoon-sized amounts of dough onto prepared baking sheets spaced about two inches apart. Bake for 10-12 minutes until edges look set but centers remain soft—trust me, they’ll firm up as they cool!

Let them rest on the baking sheet for about five minutes before transferring them to wire racks to cool completely. Finally, sprinkle some rainbow sprinkles on top while still warm because who doesn’t want their treats looking fabulous?

Enjoy these Cosmic Brownie Cookies fresh from the oven or store them in an airtight container where they won’t last long—trust me!
