Kitchn has published a from-scratch Cosmic Brownies recipe that makes eight brownies, with a bittersweet chocolate base, ganache topping and rainbow candy-coated chips. The recipe takes about 25 minutes to prepare and 30 minutes to bake, followed by cooling and chilling time. Its published testing comments are positive, but those are recipe-test feedback rather than independent nutritional or taste comparisons.
Kitchn has published a homemade Cosmic Brownies recipe that makes eight chocolate bars topped with ganache and rainbow candy-coated chocolate chips. The recipe offers home bakers a from-scratch version of the packaged snack, with about 25 minutes of preparation and 30 minutes in the oven, plus time to cool and chill the brownies before slicing.
The recipe’s brownie base uses all-purpose flour, Dutch-process cocoa powder, bittersweet chocolate, butter, eggs, sugar and vanilla. The chocolate and butter are melted together, then mixed with the eggs, sugars and vanilla. The dry ingredients are folded in just until combined; the recipe warns that overmixing can make the brownies more cakey instead of dense and fudgy.
The brownies bake at 325°F for 28 to 30 minutes, until the edges are set and a tester comes out with a few moist crumbs. They should cool completely, which the recipe estimates will take about an hour. A topping made from bittersweet chocolate and heavy cream is then poured over the cooled base, spread evenly and finished with rainbow candy-coated chocolate chips. The brownies need chilling time for the ganache to set before they are cut.
The recipe lists eight servings and estimates 25 minutes of preparation and 30 minutes of cooking. It suggests mini M&M’s as an alternative if rainbow candy-coated chocolate chips are difficult to find. The source describes the topping as ganache, rather than a separate buttercream frosting, and recommends heavy cream rather than milk or half-and-half for its texture.
A Packaged Favorite, Made at Home
The recipe is aimed at readers who want to make a familiar snack-style brownie from scratch, with control over the ingredients and a fresh-baked base. Its approach keeps the visual markers of the packaged treat—the chocolate topping and colorful chips—while using bittersweet chocolate in both the batter and ganache. That may appeal to bakers looking for a more pronounced chocolate flavor, though the source does not provide a blind taste test or a measured comparison with the original product.
The method also makes timing part of the practical story. Although active preparation and baking total about 55 minutes, cooling and chilling add time before the brownies are ready to slice. Readers planning to serve them should account for that wait rather than treating the listed prep and cook times as the full time from start to finish.

How the Recipe Builds Its Texture
The recipe’s texture depends on its ingredient choices and handling. Kitchn says Dutch-process cocoa gives the brownies a deeper color and a mellower chocolate flavor than natural cocoa, while all-purpose flour provides structure without aiming for a cake-like crumb. The recipe says natural cocoa can be used if needed, with a lighter color and sharper flavor expected; it advises against cake flour or gluten-free flour blends for the same result.
For the topping, the recipe calls for bittersweet chocolate and heavy cream. It recommends a chocolate bar for a smooth ganache, while noting that chocolate chips can also work. Once the ganache has been spread over the cooled brownies and the candy pieces added, chilling helps the surface set for cleaner slicing. A shallow line across the center can be pressed into each piece with the back of a butter knife as a nod to the original snack’s appearance.
““This is truly the ultimate cosmic brownie recipe. We absolutely loved this recipe!””

Serving Time and Nutrition Details
The source gives preparation and oven times, but does not include one total estimate covering cooling and chilling. It says the base needs about an hour to cool completely, then calls for chilling until the ganache is set without specifying a duration. The actual wait will depend on conditions and how firmly set a baker wants the topping.
The provided source material also does not state calories, full nutrition information, storage duration or a food-safety shelf life. It does not report a gluten-free adaptation in the excerpt, although it notes that changing the flour can affect the texture. Readers with allergies should check the labels on chocolate, candy and other ingredients: the recipe includes dairy, eggs and wheat, and some candy products may have additional allergens or cross-contact warnings.
Cooling, Chilling and Slicing
The next steps for anyone making the recipe are to let the baked brownies cool completely, prepare and spread the ganache, add the candy-coated chips, and refrigerate the pan until the topping is set. The recipe then calls for slicing the brownies and making the shallow center ridge. Further reporting or recipe updates would be needed to establish a specific chilling time, storage guidance or nutrition values; none is supplied in the source excerpt.
