Immerse yourself in the captivating realm of Cosmic Brownie Cookies, a creation that guarantees to transport your taste buds on an adventure. Every cookie is a work of art blending the intense flavors of sweet chocolate with the soft crumb of a flawlessly baked brownie. If that wasn’t enticing enough they are adorned with a chocolate ganache adding an extra layer of velvety indulgence. The finishing touch comes from a sprinkle of rainbow candy-coated chocolate chips not only infusing playful bursts of color but also introducing an enjoyable contrast, in texture.



Ingredients for Brownie Cookies:

8 ounces semi-sweet baking chocolate

1/4 cup salted butter

1/2 cup all-purpose flour, spooned and leveled

2 tablespoons cocoa powder

1/2 teaspoon baking powder

1/4 teaspoon salt

1/2 cup brown sugar

1/2 cup granulated sugar

2 large eggs, at room temperature

1 teaspoon vanilla extract

Ingredients for Chocolate Ganache:

3/4 cup semi-sweet chocolate chips

3 tablespoons heavy cream

1/4 cup rainbow candy-coated chocolate chips


Preheat your oven to 350 degrees Fahrenheit.

Line a baking sheet, with parchment paper.

Create the Cookie Dough:

In the microwave melt 8 ounces of sweet baking chocolate and 1/4 cup of salted butter together stirring every 20 seconds until smooth.

In a bowl whisk together 1/2 cup of all-purpose flour, 2 tablespoons of cocoa powder, 1/2 teaspoon of baking powder and 1/4 teaspoon of salt.

In a bowl whisk together 1/2 cup each of sugar and granulated sugar with 2 large eggs for approximately 5 minutes until frothy.

Add in the melted chocolate-butter mixture. Stir in 1 teaspoon of vanilla extract.

Gently fold in the flour mixture until it is just combined.

Bake the Cookies:

Using a scoop or spoon place portions of dough that are 1 & 1/2 tablespoons onto the prepared baking sheet. Make sure to space them two inches from each other.

Bake for 8 to 9 minutes until the edges are firm and the tops have a cracked appearance.

Allow the cookies to cool completely on the baking sheet.

Prepare the Chocolate Ganache:

Take a bowl and add in three quarters (3/4) cups of sweet chocolate chips.

Heat three (3) tablespoons of heavy cream, in the microwave until it is hot but not boiling. This usually takes forty (40) seconds.

Finish the Cookies:

Start by pouring the cream onto the chocolate chips. Allow it to sit for a minute and then stir until the mixture becomes smooth.

If there are any remaining chunks of chocolate you can microwave the mixture for a few seconds to melt them completely.

Now let’s move on to finishing the cookies. Take the cookies. Evenly spread the ganache on top of each one.

Sprinkle 1/4 cup of rainbow candy-coated chocolate chips, over the ganache layer.

Place the cookies in the refrigerator for 20 minutes to allow the ganache to set.

Finally, your delicious Cosmic Brownie Cookies are ready! Enjoy!


To make these Cosmic Brownie Cookies gluten-free you just need to make adjustments. Instead of all-purpose flour opt, for a high-quality blend of gluten-free flour. Look for one that is designed to be a 1:1 substitute, for wheat flour and preferably includes xanthan gum, which helps bind the ingredients in the absence of gluten.

When choosing your chocolate and cocoa powder double-check that they are certified gluten-free because some chocolate products may contain gluten additives. When it comes to the rainbow candy-coated chocolate chips it’s important to select a brand specifically labeled as gluten-free to avoid any cross contamination.
