    How to use this Oreo Frosting

    • Cupcakes: Pipe the frosting with a piping bag onto my favorite vanilla cupcakes or these moist chocolate cupcakes for a delightful Oreo twist on a classic treat.
    • Brownies: Frost a batch of rich chocolate brownies with Oreo buttercream for an indulgent dessert.
    • Cookies: Sandwich two cookies together with Oreo buttercream for homemade Oreo cookie sandwiches.
    • Dessert Bars: Use the frosting to top off dessert bars, like brownie bars or blondies, for an extra layer of flavor.
    • Cake Pops: Use the frosting to bind together my buttermilk chocolate cake and then dip them in chocolate for delightful Oreo cake pops.

    Tips for this recipe

    • Quality ingredients: Use quality ingredients for the best taste and texture.
    • Ingredient temperature: Make sure the butter is at room temperature before starting.
    • Clean, dry equipment: Before you start, make sure all your utensils and mixing bowl are clean and dry. Grease or water residues can compromise the texture of the buttercream.
    • Pasteurize the eggs: Melt the sugar and egg whites in a double boiler, stirring constantly until the sugar is completely dissolved. This will help eliminate any risk of bacterial contamination from the raw egg whites.
    • Beat until stiff: Beat the egg whites and sugar until they form stiff, glossy peaks. This may take several minutes, so please be patient.
    • Softening the mixture: Mix the buttercream for at least 2 minutes at a slow speed, using a paddle attachment or a rubber spatula to remove air bubbles and obtain a smooth frosting.

    Storage instructions

    In the fridge/room temperature: Leftover frosting can be stored in the fridge for up to 1 week in an airtight container. After refrigeration, allow the frosting to come back to room temperature or gently warm and re-whip it.

    Freezing: You can also store it in the freezer for up to 3 months in a freezer-safe container. Let it thaw slowly in the fridge.

    Variations & Substitutions

    • American Oreo Buttercream : To use the traditional American Buttercream recipe (butter and confectioners sugar) follow my recipe for whipped vanilla buttercream and add the same amount of oreo.
    • Mint Oreo Buttercream: Add a dash of mint extract to the frosting for a refreshing twist.
    • Peanut Butter Oreo Buttercream: Incorporate creamy peanut butter into the frosting for a rich and nutty flavor.
    • Oreo whipped cream frosting: For a lighter version try my recipe for Oreo frosting made with mascarpone cheese or cream cheese like this Oreo cream cheese frosting.
    • Caramel Oreo Buttercream: Drizzle caramel sauce into the frosting and mix until well combined for a sweet and gooey flavor like this salted caramel Swiss buttercream.
    • Hazelnut Oreo Buttercream: Add hazelnut spread (such as Nutella) to the frosting for a rich and nutty flavor.
    • Cookies and Cream Frosting: Fold crushed Oreos into the frosting perfect to use as oreo filling inside a cake and get the crunchy texture of crushed oreo cookies.
    • Nutella and Oreo Buttercream: Make a mix of this frosting and my Nutella buttercream recipe.
    • Replace Oreos: with other dried cookies of your choice, such as Biscoff cookies and some cookie butter spread.
