Fudgy Cosmic Brownie Cookies

Our Cosmic Brownie Cookies recipe is inspired both by the renowned Crumbl Cookies and by Little Debbie Cosmic Brownies, but even better than the bakery-bought item or lunch box treat!

These fudgy, chewy, deliciously dense desserts are so easy to make; it takes only 10 minutes to prepare the brownie batter and 11 more minutes to bake.

The 2 ingredient ganache comes together quickly by melting chocolate with heavy cream in the microwave (no cooking needed), then it hardens into the perfect fudge frosting that holds the colorful rainbow candy in place.

How to Make Cosmic Brownie Cookies

    Pro Tip: Scrape along the bottom of your mixing bowl with a spatula to ensure no pockets of flour or cocoa powder remain.
  2. Bake The Brownie Cookies: Bake at 350 degrees Fahrenheit, 6 at a time, for 11 minutes per batch.
    Pro Tip: The cookies should be about 2 inches in diameter.
  3. Make The Chocolate Mixture: Melt the chocolate and heavy cream in the microwave in 30-second intervals, stirring after each interval.
  4. Dip And Decorate: Dip the top of each cooled cookie into the melted chocolate and top with mini M&M’s.
  5. Serve: Serve and enjoy!

Tips For Making The best Cosmic Brownie Cookies

  • In addition to mini M&M’s, you can use candy-coated chocolate chips. These can be found at craft stores like Hobby Lobby but will be more expensive.
  • Make sure your butter is at room temperature so that it creams well with the sugars.
  • You can line your pan with parchment paper or foil for easy cleanup.

How to Store Cosmic Brownie Cookies

  • To Store: These cookies are best stored in an airtight container on the counter. They will stay fresh for about 5 days at room temperature.
  • To Freeze: Freeze these cosmic brownie cookies for up to 3 months in a freezer-safe container. When you’re ready to eat them, thaw them overnight in the refrigerator.

Frequently Asked Questions

What type of cocoa powder should I use for this recipe?

You can use either Dutch process cocoa powder or regular cocoa powder in this recipe. Dutch process will give the cookies a deeper, richer chocolate flavor. If you do that, I recommend using a semi-sweet or milk chocolate topping, so the chocolate flavor is not too bitter.

What is the taste and texture of these Cosmic cookies?

These cookies have a thick, dense texture with a nice chew to them. They remind me of a soft peanut butter cookie, but taste like a rich, fudgy chocolate brownie.
