Kitchn has published a homemade version of Cosmic Brownies, the packaged Little Debbie snack. The recipe makes eight brownies and uses a bittersweet chocolate base, chocolate ganache and rainbow candy-coated chocolate chips.
Kitchn has published a homemade Cosmic Brownies recipe that recreates the packaged Little Debbie treat with a dense chocolate brownie, a bittersweet chocolate ganache and rainbow candy-coated chocolate chips. The recipe makes eight brownies, offering home bakers a from-scratch version of the familiar snack.
The recipe lists 25 minutes of preparation and 30 minutes of baking. 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 then need to cool completely before the ganache goes on; the instructions estimate about an hour for cooling.
The brownie batter uses all-purpose flour, Dutch-process cocoa powder, bittersweet chocolate, butter, eggs, sugars and vanilla. Kitchn advises folding the dry ingredients in only until combined, saying overmixing can make the result cakier rather than fudgy. For the topping, melted chocolate and heavy cream form a ganache that is spread over the cooled brownies.
Rainbow candy-coated chocolate chips provide the recognizable colorful finish. Kitchn says mini M&M’s can be used if those chips are unavailable. After the topping is added, the brownies are chilled until the ganache sets, then sliced. The recipe also suggests pressing a shallow ridge across each piece with the back of a butter knife as a visual nod to the packaged original.
A Packaged Treat, Made at Home
The recipe gives readers a practical way to reproduce a familiar lunchbox-style dessert using standard baking steps and ingredients, with a few specialty choices. Its most useful distinctions are texture and topping: the brownie is intended to stay dense and fudgy, while heavy cream helps the ganache set into a layer that can be cut cleanly.
Ingredient flexibility may make the recipe easier to use. The report says chocolate chips can stand in for a chocolate bar in the ganache, though it recommends a good-quality bittersweet bar for the smoothest result. Mini M&M’s are offered as an alternative decoration. The recipe does not claim to be an exact commercial replica; it presents itself as a homemade take on the original.
For readers planning ahead, cooling and chilling are part of the process, not optional finishing details: the brownies must cool before the ganache is spread, and the topping needs time to set. The listed prep and bake times do not include all of that waiting time.

How the Recipe Recreates the Original
The Kitchn report describes the commercial snack as a dense brownie topped with chocolate frosting and rainbow candy pieces. Its homemade version keeps those recognizable elements while changing the preparation: the brownie is made with real bittersweet chocolate, and the top layer is a quick ganache made from chocolate and heavy cream.
The recipe credits Natcha Nikki Jessop, a New York-based food stylist, recipe developer and culinary producer. The report also identifies Janette Zepeda as a senior culinary producer and includes her assessment as a recipe tester. Kitchn says Jessop trained in culinary arts at Institut Paul Bocuse, now Institut Lyfe, and has experience developing recipes and working in a Paris pastry shop.
In a tester note dated September 2026, Zepeda praised the brownies’ soft texture and ganache topping and said they were popular with her children. That is her reported experience, rather than independent evidence about how all bakers or households will find the recipe.
Details the Report Does Not Give
The source report does not provide independent testing results, reader feedback or comparisons with the packaged brownies. Descriptions such as “fudgier” and “richer” are the recipe’s characterization, not measurements against the commercial product.
The report gives the baking temperature and time, but the supplied material does not specify the required pan size, exact ingredient quantities, or how long the brownies should chill before slicing. Those details may appear in the full recipe page, but they cannot be confirmed from the material provided here. It also does not give nutrition information or a specific storage duration.
The source says the candy-coated chips may be difficult to find and offers mini M&M’s as a substitute. It does not provide a gluten-free adaptation in the supplied text; that section ends after beginning to describe a flour swap, so no complete alternative can be verified.
Cooling, Chilling and Serving
The next steps for anyone making the recipe are to let the brownies cool fully, spread on the ganache, add the candy pieces and chill until the topping has set. The brownies can then be sliced, with the shallow center ridge added using the back of a butter knife, as Kitchn describes.
Readers seeking exact quantities, pan dimensions, storage guidance or the complete dietary substitutions should consult the full recipe page. The supplied report does not state a later publication, product launch or other scheduled development; the immediate next milestone is simply completion of the recipe at home.
Because the source does not provide food-storage instructions, bakers should follow established food-safety guidance for prepared desserts and avoid leaving perishable ingredients at room temperature for extended periods. The recipe includes wheat, eggs and dairy; check the chocolate and candy labels for additional allergens or cross-contact warnings.
Key Questions
How many brownies does the recipe make?
Kitchn lists a yield of eight brownies.
How long does the recipe take?
The listing gives 25 minutes of prep and 30 minutes of cooking. It also calls for about an hour of cooling and additional chilling time for the ganache to set, so the total elapsed time is longer.
What can replace rainbow candy-coated chocolate chips?
The report suggests mini M&M’s as the easiest alternative if the specialty chips are unavailable.
What allergens are present?
The listed ingredients include wheat, eggs and dairy, including butter and heavy cream. Chocolate and candy products may contain other allergens or carry cross-contact warnings, so check their packaging.
Does the recipe include a gluten-free version?
The supplied report begins to mention a gluten-free flour swap but cuts off before giving complete instructions. A reliable gluten-free version cannot be confirmed from the provided material.
