Oreo frosting is the ultimate treat for cookies and cream lovers. This luscious, creamy buttercream is studded with crushed Oreo cookies, making it perfect for topping cakes, cupcakes, brownies, or even as a decadent dip. The combination of smooth vanilla frosting and crunchy chocolate cookie bits creates a nostalgic flavor that’s always a crowd-pleaser.
Ingredients
- 1 cup (2 sticks) unsalted butter, room temperature
- 3 1/2 cups powdered sugar, sifted
- 2 tablespoons heavy cream (plus more as needed)
- 1 teaspoon pure vanilla extract
- 1/4 teaspoon fine sea salt
- 12 Oreo cookies (regular, not Double Stuf), finely crushed
Instructions
- Crush the Oreos: Place the Oreo cookies in a food processor and pulse until you have fine crumbs. Alternatively, put them in a zip-top bag and crush with a rolling pin. Set aside.
- Beat the butter: In a large mixing bowl, beat the softened butter with an electric mixer (stand or hand) on medium-high speed until smooth and creamy, about 2-3 minutes. Scrape down the sides as needed.
- Add powdered sugar: Gradually add the sifted powdered sugar, about 1 cup at a time, beating on low speed after each addition. Once incorporated, increase speed to medium and beat until fluffy, about 1 minute.
- Add cream, vanilla, and salt: Pour in the heavy cream, vanilla extract, and salt. Beat on medium-high for another 1-2 minutes, until light and smooth. If the frosting seems too thick, add a splash more cream (1 teaspoon at a time) until you reach a spreadable consistency.
- Fold in Oreo crumbs: Add the crushed Oreos and gently fold with a spatula until evenly distributed. Avoid overmixing, as this can turn the frosting gray.
- Use or store: Use immediately to frost cooled cakes or cupcakes, or cover and refrigerate until ready to use. If refrigerated, let it come to room temperature and re-whip briefly before using.
Tips
- Crushing Oreos: For the smoothest piping, pulse the cookies until they’re very fine crumbs. Larger chunks may clog piping tips.
- Substitutions: You can swap heavy cream for milk, but the frosting will be slightly less rich. Dairy-free? Use a vegan butter and plant-based milk.
- Consistent texture: Sift powdered sugar to avoid lumps, and ensure butter is truly room temperature for the creamiest result.
- Don’t overmix: After adding the Oreos, fold gently. Overmixing can cause the cookie crumbs to break down and tint the frosting grayish.
Serving Suggestions
- Classic cupcakes: Pipe tall swirls onto chocolate or vanilla cupcakes for a bakery-style look. Top with mini Oreos.
- Layer cakes: Spread generously between cake layers and over the outside for a cookies-and-cream cake.
- Brownie topping: Slather on cooled brownies for an extra-indulgent treat.
- Dessert dip: Serve as a dip for pretzels, graham crackers, or fresh fruit at parties.
- Ice cream sundaes: Dollop on top of sundaes or milkshakes for an Oreo twist.
Variations
- Chocolate Oreo Frosting: Add 1/4 cup unsweetened cocoa powder with the powdered sugar for a chocolatey base.
- Peanut Butter Oreo Frosting: Beat in 1/3 cup creamy peanut butter with the butter for a nutty upgrade.
- Mint Oreo Frosting: Use Mint Oreos and add 1/4 teaspoon peppermint extract for a refreshing flavor.
- Extra Cookies & Cream: Fold in additional chopped Oreos for more crunch and texture.
- Reduced Sugar: Use 2 1/2 cups powdered sugar for a less-sweet, slightly denser frosting. Add more cream to adjust consistency as needed.
Storage and Reheating
Store Oreo frosting in an airtight container in the refrigerator for up to 5 days. Before using, let it sit at room temperature for 30-45 minutes to soften. If the frosting is too firm, beat it briefly with a mixer to restore its creamy texture. For longer storage, freeze in a sealed freezer bag or container for up to 2 months. Thaw overnight in the fridge, then bring to room temperature and re-whip as needed. Do not microwave to soften, as this can melt the butter and ruin the texture.
Frequently Asked Questions
- Can I use Double Stuf or flavored Oreos in the frosting?
- Yes, you can use Double Stuf or any Oreo flavor you like. Double Stuf will make the frosting slightly sweeter and softer, so you may want to use a touch less cream. Flavored Oreos (like Golden, Mint, or Birthday Cake) will add their unique twist—just keep in mind the filling color may affect the final frosting hue.
- Can I make Oreo frosting ahead of time?
- Absolutely! Oreo frosting can be made up to 5 days in advance. Store it airtight in the fridge. For best texture, let it come to room temperature and re-whip before using, as the cookie crumbs can firm up the frosting when chilled.
- How do I make the frosting stiffer for piping?
- If you want a firmer frosting for piping tall swirls or decorative borders, add a bit more powdered sugar (1/4 cup at a time) until you reach the desired stiffness. Chill the frosting for 10-15 minutes before piping for extra structure, especially in warm kitchens.
- Is this frosting suitable for layer cakes?
- Yes, Oreo frosting is sturdy enough for filling and frosting layer cakes. Be sure to use finely crushed cookies to maintain a smooth texture for spreading and stacking. If you want extra stability, especially for taller cakes, add a bit more powdered sugar or chill the frosted cake briefly before serving.
- Can I color Oreo frosting with food coloring?
- Because Oreo crumbs create a speckled, grayish-tan effect, adding food coloring may not yield vibrant colors. Gel food coloring works best if you want a subtle tint, but the cookie bits will always show through. For bright colors, consider making a plain buttercream for the base and using Oreo frosting only as a filling or accent.
- Why does my Oreo frosting look gray?
- This can happen if the cookie crumbs are too finely ground or if the frosting is overmixed after adding them. To keep your frosting looking creamy white with distinct cookie specks, fold in the Oreos by hand and stop as soon as they’re distributed.
