Baking Cosmic Brownie Cookies Made Simple

Step 1: Warm Up the Oven

Get your oven ready by heating it to 350°F.

Cover two baking sheets with parchment paper or silicone mats to prevent sticking.

Step 2: Whip Together Cookie Base

In a large mixing bowl, blend softened butter and sugar until the mixture looks fluffy and light.

Add eggs one by one, stirring thoroughly after each addition.

Pour in vanilla extract for extra flavor.

Separately, combine dry ingredients:

All-purpose flour
Cocoa powder
Baking soda
Salt

Slowly mix dry ingredients into wet mixture until just combined.

Gently fold chocolate chips into the dough.

Step 3: Create Cookie Rounds

Scoop rounded tablespoons of dough onto prepared baking sheets.

Space cookies about 2 inches apart.

Press down gently on each cookie to flatten slightly.

Step 4: Bake Cookies

Slide trays into the oven and bake for 8-10 minutes.

Cookies should have set edges but soft centers.

Remove from oven and let rest on baking sheets for 5 minutes before moving to cooling rack.

Step 5: Craft Chocolate Ganache

Place chocolate chips in a heat-safe bowl.

Heat heavy cream in a small pan until it barely simmers.

Pour hot cream over chips and wait 2-3 minutes.

Stir until smooth and glossy.

Step 6: Decorate with Flair

Once cookies are completely cool, spread ganache generously across each cookie.

Immediately sprinkle with colorful candy chips or rainbow sprinkles.

Let ganache set at room temperature or chill in refrigerator for faster results.

Step 7: Serve and Savor

Plate these delightful treats and enjoy the rich, fudgy goodness of homemade Cosmic Brownie Cookies!

Add an extra tablespoon of cocoa powder for deeper, richer chocolate flavor that makes these cookies even more decadent.
Chill the dough for 30 minutes before baking to help cookies maintain their shape and prevent excessive spreading on the baking sheet.
Ensure chocolate chips are completely melted by stirring gently and consistently, creating a smooth, glossy topping that sets beautifully.
Swap butter with coconut oil and use gluten-free flour blend to make these cookies suitable for dairy-free and gluten-sensitive individuals.
Keep cookies in an airtight container at room temperature for up to 5 days, separating layers with parchment paper to prevent sticking.

Keep Cosmic Cookies Soft After Baking

Place cooled cookies in an airtight container, separating layers with parchment paper. Store for up to 5 days in the refrigerator, keeping ganache firm and fresh.
Wrap individual cookies tightly in plastic wrap, then place in a freezer-safe container. Freeze for maximum 3 months. Thaw at room temperature for 30 minutes before serving.
Keep cookies in a sealed container at room temperature for 2-3 days. Ensure container is completely closed to maintain moisture and prevent staleness.
Warm cookies briefly in microwave for 10-15 seconds or place in oven at 300°F for 2-3 minutes to restore soft, gooey texture. Check carefully to prevent overcooking.
