Ingredients

• 225g (1 cup) Unsalted Butter: Softened to room temperature (around 65°F/18°C).
• 400g (3 1/2 cups) Powdered Sugar: Sifted to ensure a silky, lump-free texture.
• 100g (1 cup) Oreo Cookies (about 10-12 cookies): Finely crushed into fine crumbs.

• 1.5g (1/4 tsp) Fine Salt: Cuts through the intense sweetness and balances flavor.

How to make

Phase 1: Preparing the Cookie Crumbs & Butter Base

1. Crush the Cookies: Place the Oreo cookies (wafers and cream filling included) into a food processor and pulse until they form ultra-fine crumbs. Alternatively, seal them in a zip-top bag and crush thoroughly with a rolling pin.
2. Whip the Butter: In a large mixing bowl or the bowl of a stand mixer fitted with the paddle attachment, beat the softened unsalted butter on medium-high speed for 4 to 5 minutes until it turns pale, creamy, and voluminous.

Phase 2: Mixing & Aerating the Frosting

3. Add Sugar & Liquids: Lower the mixer speed to low. Gradually add the sifted powdered sugar one cup at a time, alternating with tablespoons of heavy cream and vanilla extract.
4. Beat Until Fluffy: Once incorporated, add the salt, turn the mixer speed to medium-high, and whip for another 2 to 3 minutes until light and fluffy.
5. Fold in Cookies: Gently fold in the finely crushed Oreo crumbs using a silicone spatula or on the lowest mixer speed until evenly distributed throughout the buttercream.
6. Smooth Out Air Bubbles: Use a rubber spatula to hand-paddle the frosting against the sides of the bowl for 1 minute to push out large air pockets for smooth piping.

How To Serve

• Cupcake Swirls: Pair with rich dark chocolate, vanilla, or cookies-and-cream cupcakes using a wide piping tip (such as a 1M or 2A tip).
• Layer Cake Filling: Spread generously between cake layers, pairing seamlessly alongside our Oreo Frosting or silky Swiss Meringue Buttercream variations.
• Cookie Sandwich Filling: Pipe between two homemade chocolate chip or brownie cookies for an over-the-top sweet treat.

How To Store

• Room Temperature: Store in an airtight container in a cool room for up to 2 days.
• Refrigerator: Keep refrigerated in a sealed container for up to 2 weeks. Before using, bring to room temperature and re-whip for 1–2 minutes to restore fluffiness.
• Freezer: Freeze in a freezer-safe bag or container for up to 3 months. Thaw overnight in the fridge, bring to room temperature, and re-whip before piping.

FAQs

Why is my frosting clogging my piping tip?

If your cookie crumbs are too large, they will block small piping nozzles. Make sure to process your cookies into a fine, dust-like powder, or use large open star or round piping tips (like Wilton 1M or 2A).

Can I use Golden Oreos instead of classic chocolate Oreos?

Absolutley! Using Golden Oreos creates a delicious vanilla-forward cookies-and-cream buttercream with a lighter color profile.

How do I fix frosting that is too soft or too stiff?

If the frosting is too soft, chill it in the fridge for 10 to 15 minutes or beat in an extra 30g (1/4 cup) of powdered sugar. If it is too stiff, beat in an extra teaspoon of heavy cream at a time.

Note

• Do Not Remove Oreo Cream Filling: Leave the white cream filling inside the cookies when crushing them! It adds flavor and moisture directly into the buttercream.
• Room Temperature Butter is Key: Butter that is too cold will result in lumpy frosting, while melted butter will make the frosting greasy and runny.

Tips and Tricks

• Use Dutch-Process Cookie Crumbs: For an even deeper black cocoa look and flavor, mix in 1 teaspoon of dark cocoa powder alongside your crushed cookies.
• Sift Powdered Sugar: Always sift your powdered sugar before adding it to butter to eliminate clumps and guarantee a silky-smooth mouthfeel.
• Paddle Attachment Over Whisk: Use the paddle attachment on your stand mixer rather than the wire whip to keep unwanted large air bubbles out of your finished buttercream.
