This Oreo Frosting is rich, creamy, and packed with real chocolate sandwich cookies, making it a go-to frosting for cakes, cupcakes, and sheet cakes alike. Made with cream cheese and butter for structure and flavor, it spreads smoothly and pipes beautifully.

Some frostings are nice to have in your back pocket, while others immediately prompt people to ask for the recipe. This Oreo frosting is firmly in the second category. It’s the kind of frosting that turns a simple chocolate cake into something special and makes vanilla cupcakes disappear faster than expected.

I’ve tested a lot of cookies-and-cream frostings over the years, and this one hits the balance I want every time. It’s not overly sweet, it tastes unmistakably like Oreo cookies, and it holds its shape without feeling stiff or dense. The cream cheese gives it structure and a subtle tang that keeps the sweetness in check, while butter adds richness and that familiar frosting flavor we all expect.

• Real Oreos for authentic cookies-and-cream flavor
• Cream cheese to keep the frosting balanced and not overly sweet
• Smooth enough to spread but sturdy enough to pipe
• Easy to scale up or down depending on what you’re baking
• Pairs perfectly with chocolate, vanilla, chocolate chip, or peanut butter cakes

This frosting is incredibly versatile. I use it on layer cakes, sheet cakes, brownies, and cupcakes, and it’s sturdy enough for piping as long as the cookies are crushed finely. It’s also forgiving – if it feels too thick, a splash of milk fixes it instantly, and if it’s too soft, a quick chill firms it right up.

Ingredients and Substitutions

Below is what you’ll need to make this perfect Oreo Frosting, along with some key ingredient notes and substitutions.

• Butter: Use unsalted butter at cool room temperature.
• Cream Cheese: Use a full-fat brick-style cream cheese, also at room temperature.
• Vanilla Extract
• Confectioners’ Sugar
• Oreos: Crush the Oreos very finely if you plan to pipe the frosting so the crumbs don’t clog the tip. If you’re going to spread the frosting with a spatula, the Oreo crumbs can be a little bigger to add texture.
• Heavy Cream: Used heavy cream, or whole milk, to loosen the frosting if it is too thick.

Gluten-Free Note: For gluten-free frostng, use gluten-free chocolate sandwich cookies. The rest of the frosting is naturally gluten-free.

Dairy-Free: Substitute plant-based butter and dairy-free cream cheese; the resulting frosting will be slightly softer.

How to Make Oreo Frosting

1. Cream the Base: Beat the butter and cream cheese together until completely smooth and lump-free. Mix in the vanilla extract
2. Sweetenen Gradually: Add the powdered sugar, a little at a time, beating well between additions.
3. Adjust Consistency: If the frosting feels too thick, beat in the heavy cream one tablespoon at a time.
4. Finish with Cookies: Fold in the finely crushed Oreos until evenly distributed.

Cream Cheese for the Best Texture

A lot of Oreo frostings are just American-style buttercream frosting with crushed Oreos. But I’ve found that once you add the cookie crumbs, these frostings often feel either greasy or unstable. The flavor is there, but the texture can slump and lose definition, especially after piping. So how do we fix this? With cream cheese!

Kitchen Chemistry

Cream cheese forms a protein-stabilized fat crystal network that holds water in place, creating a more rigid, cohesive structure than butter alone, which allows the frosting to support solid mix-ins (like cookie crumbs) without collapsing.

Buttercream relies almost entirely on fat and sugar for structure, which works beautifully on its own but becomes less reliable once solid particles are introduced. Cream cheese brings milk proteins and bound water into the system, reinforcing the fat network rather than weakening it. That extra structure is what keeps this frosting smooth, pipeable, and stable even with a very generous amount of crushed Oreos.

Not to mention that the frosting tastes even better, too!

How Much Frosting to Use

This recipe makes approximately 3 1/2 cups of frosting. That’s enough for:

• 12 cupcakes: Generously frosted with swirls.
• Sheet Cake: One batch of this recipe is enough for a 9 x 13-inch half sheet with a thick layer of frosting
• Two-layer cake: One batch is enough for an 8-inch or 9-inch cake.
• Three-layer cake: Double the frosting recipe for three-layer cakes with piped swirls.
• Bundt Cake or Brownies: To spread frosting across the top of a bundt cake or a batch of brownies, half of this recipe is sufficient.

Frosting amounts are always approximate. If you love extra-thick frosting or decorative piping, make more than you think you’ll need. It’s much easier to have a little extra frosting than to run out mid-cake!

Tips and Tricks for the Best Oreo Buttercream

1. Room Temperature Ingredients: Use room temperature butter and cream cheese to avoid lumps in the frosting.
2. Crush Oreos Finely: If you plan on piping the frosting, crush the Oreos finely to avoid clogging the piping tip (a food process works well for this).
3. Chill Briefly: If the frosting is a little too soft, chill for 10-15 minutes to firm.
4. Storage: Store frosting in an airtight container in the refrigerator for up to 5 days or freeze for up to 3 months. Bring the frosting up to room temperature and rewhip it before frosting.
